For decades, India’s marketing calendar followed a predictable rhythm. Summer began in late March, peaked in April and May, and gradually gave way to monsoons. Campaigns, media spends, and retail cycles were meticulously aligned to this cadence. That certainty is now beginning to erode.
Now, summer shows up early, sometimes confused, often uneven. The North heats up before the South. Rain interrupts peak weeks. Winter seems to linger into what used to be ‘the summer build-up’. And for brands, this isn’t just a weather story; it’s a commercial one. Erratic weather patterns, early heatwave forecasts, and regional climate disparities are reshaping how brands approach one of the most critical consumption windows of the year. Summer is no longer a fixed quarter. It is a moving target. The result is a noticeable shift. Campaigns are going live weeks earlier. Budgets are being pushed forward. The idea of a neat ‘summer window’ is giving way to something far messier, and in real time.
A disrupted season
The most visible change is timing. Campaigns that traditionally launched in late March are now going live in February or early March; in a few heat-prone regions, even earlier.
As Dhiraj Sharma, Head of Marketing and PR, Panasonic Life Solutions India, puts it, “Summers are arriving earlier and consumers are starting their cooling purchase journey much sooner than they traditionally did. Keeping this in mind, we started our campaign rollout in February this year, ahead of the conventional summer window.” The company is also betting big on this shift. Panasonic is targeting 55 per cent revenue growth in its AC business for the January–June period, driven by last year’s demand slump and a planned 2.5 to 3x increase in marketing spends to capitalise on early-season demand.
Saurabh Shrivastava, Executive Vice President - Integrated Planning & Operations, Media, dentsu India, suggests that brands have advanced summer campaigns by two to three weeks, with categories such as air conditioners, beverages, personal care, and ice creams leading the shift. “Last year, it was a muted Summer AdEx due to unseasonal rains, especially in North India. This year will witness a strong recovery, and the Summer AdEx is expected to witness a 15-17 per cent growth YoY. The total brand budget is still broadly aligned with the annual marketing calendar. A significant portion of the budget will be towards the World Cup and IPL. At the same time, budgets are also channelised into retail media and quick commerce platforms, addressing the mid and bottom funnel. However, the recent geopolitical developments in the Middle East might also affect the summer AdEx this year. We will have more clarity about the situation in a couple of weeks.”
Front-loaded AdEx and a longer campaign tail
At Summercool Home Appliances, the shift is both aggressive and deliberate. Ashutosh Gupta, Director of Sales and Marketing, says, “Unpredictable heatwaves have pulled the cooling market nearly three to four weeks early. We’ve increased our AdEx this year by around 25 per cent, with greater emphasis on early visibility. We can’t afford to fall behind in this competitive market.” The brand’s decision to onboard Ajay Devgn as its ambassador is part of this early push, aimed at building visibility and trust before the market gets crowded. The results so far suggest introductory gains. “We are witnessing a sales spike of around 30 per cent, supported by increasing dealer inquiries and improved retail footfalls,” Gupta adds.
For many brands, while spending is getting front-loaded, overall annual budgets remain broadly aligned with marketing calendars, with brands reallocating more towards first-phase digital and performance channels.
Saheb Singh, Director, Strategy, AGENCY09, emphasises that India’s advertising market has been on an overall steady growth trajectory. “According to industry estimates such as MAGNA, India’s total AdEx crossed `1.27 lakh crore in 2024 and was projected to grow further in 2025, with digital continuing to drive a significant share of that growth.”
From fixed calendars to fluid windows
Perhaps the most profound shift is philosophical. Marketing is no longer being planned around fixed seasonal windows. Instead, brands are moving toward what industry experts describe as ‘climate-adaptive marketing.’ This approach relies on real-time data, weather forecasts, and regional demand signals to trigger campaigns dynamically.
At women’s fashion brand Shree, this shift is already embedded into planning. Amit Arora, CIO, explains that campaign calendars today are increasingly aligned with climate signals and demand forecasting rather than fixed seasonal dates. This reflects a broader shift from season-led to demand-led marketing. The brand launched its Summer ’26 campaign a couple of weeks earlier than last year to capture early consumer intent and reduce peak-season dependency, reflecting a stronger reliance on data-led decision-making.
This shift is also influencing how budgets are deployed. While overall spends remain broadly stable, with around 2 per cent of annual sales allocated to marketing, the allocation has changed significantly. Investments are being front-loaded into the early phase of campaigns to drive stronger early traction, improve ROI, and optimise CPR, before tapering later in the season.
Crucially, this approach is being driven by changing consumer behaviour. Customers are beginning their summer purchases earlier, clearly shifting the demand window forward and prompting brands to align launches, promotions, and messaging with this shift. As a result, early activation is delivering better-quality revenue. It’s also reducing reliance on heavy end-of-season discounting.
Girish Hingorani, VP, Marketing (Unitary Cooling Products) & Corporate Comm, Blue Star, highlights the growing unpredictability, “We are seeing troughs and spikes in weather patterns. Sometimes there is rain, sometimes it’s very hot. Marketers have to create campaigns that are flexible enough to change depending on the season.”
This has led to the rise of what he calls ‘micro-surgical strikes.’ “Certain markets may not be doing well, so it’s better to hold back. In markets that are heating up, you increase investments. Digital allows us to target those cities as soon as temperatures rise.” This hyper-local approach marks a departure from traditional mass media strategies, where campaigns were rolled out uniformly across the country. Now, the north, west, and south may each have different campaign timelines, depending on when the heat arrives.
Balancing media, inventory and retail readiness
Advancing campaigns is only one part of the equation. The real challenge lies in aligning media investments with supply chain readiness and retail stocking. If demand is generated but inventory is not in place, brands risk losing both sales and credibility.
Abhishek Shetty, Marketing Head, Swiggy Instamart & Pvt Brands notes, “Weather is no longer just a seasonal backdrop, it’s a real-time demand trigger. Consumers aren’t waiting for the calendar to signal summer, they’re responding to how it feels in the moment. For platforms like Instamart, that means anticipating micro-shifts in demand as it happens. Climate volatility is making consumption more fluid, and the real advantage lies in moving from seasonal planning to real-time relevance.”
Panasonic’s strategy reflects an integrated approach. “We look at this as an integrated go-to-market strategy where media deployment, retail preparedness, and supply chain planning move in tandem,” says Sharma. The company is combining ATL visibility with digital, e-commerce, and on-ground activations, ensuring that awareness translates into availability.
Digital takes the lead
In this new environment, digital and performance marketing are emerging as the backbone of summer strategies. Their ability to respond to real-time signals, dynamically optimise campaigns, and target specific geographies makes them indispensable in a volatile climate scenario. Dentsu notes that brands are increasingly using geo-targeting and dynamic creative optimisation to align messaging with local weather conditions. This is particularly relevant for categories like cooling appliances, where demand is highly temperature-sensitive.
Hingorani explains, “We are changing our digital campaigns based on cities that are getting hot. The moment temperatures rise, we target our advertising there.” At the same time, brands are being cautious about large-scale ATL investments until demand stabilises across regions. “We are still cautious until the entire country heats up. Right now, we are balancing digital, CTV, and performance marketing with front-end conversions at the store level,” he adds.
This cautious approach reflects the risks associated with unpredictable weather. A sudden drop in temperatures or unseasonal rain can derail demand, forcing brands to recalibrate spends.
The IPL factor
The Indian Premier League continues to dominate the summer advertising landscape. However, its role is evolving in the context of changing weather patterns. On one hand, IPL offers unmatched scale and reach, making it a powerful platform for brand visibility. On the other hand, the fragmentation of viewership across TV, CTV, and mobile is complicating media planning.
Hingorani points out, “IPL is becoming very complex. Earlier, you could plan for a certain frequency of ads per match. Now, with impression-based buying and multiple formats, it’s harder to control reach and frequency.”
Despite these challenges, IPL remains a key component of summer strategies, particularly for brands seeking rapid scale. However, not all brands can afford to participate at the same level. For others, the focus is on leveraging the IPL ecosystem creatively.
Does early advertising expand demand or just shift it?
One of the most debated questions is whether early campaigns actually grow the market or simply bring forward purchases. The answer is nuanced. From a performance perspective, early campaigns offer clear advantages. They allow brands to capture high-intent consumers before competition intensifies, often resulting in better conversion rates and lower acquisition costs. Dentsu notes that early campaigns can deliver stronger ROI in the initial phase, as they avoid peak-season bidding wars and allow for optimisation over a longer period. Sharma believes early engagement can expand the category. “Launching campaigns earlier allows brands to enter the consumer’s decision journey sooner and build awareness gradually. It helps expand the overall conversation around cooling rather than simply shifting purchase cycles,” he notes.
However, others are more cautious.
Navin Kathuria, Executive Vice President – Media Planning & Buying, Mudramax, suggests that the impact on ROI may be limited. “Early starters may gain visibility, but whether this meaningfully impacts ROI remains debatable. Campaigns still need to achieve their KPIs within the summer window.”
Hingorani echoes this pragmatism. “It’s better to focus your money in April and May, which are the safest bets. Though clutter is high, those are the periods when most parts of the country get hot.” The reality likely lies somewhere in between. Early campaigns can capture incremental demand, particularly from first-time buyers and upgrade- seekers, but they also risk spreading budgets too thin across an extended season.
Creative evolution
As weather patterns change, so does the nature of communication. Traditional summer advertising often relied on aspirational imagery, families enjoying cool comfort or refreshing beverages. Today, messaging is becoming more functional and urgency-driven, reflecting consumer concerns around heat, energy efficiency and reliability. Panasonic’s approach illustrates this shift.
“Consumers today are far more conscious of rising temperatures and energy efficiency. Communication increasingly highlights dependable cooling during extreme heat and intelligent features that enhance everyday living,” says Sharma. At the same time, brands are moving toward modular, adaptable creative frameworks that can evolve over the course of a longer season. This is essential to avoid creative fatigue, particularly as campaigns now run for four to five months instead of three.
The rise of commerce-led media
Another key trend is the integration of commerce into media strategies. With quick commerce players promoting seasonal bundles earlier, brands are aligning their media bursts with product availability on these platforms. This ensures that consumer intent can be converted immediately, without friction. Dentsu highlights the growing importance of retail media and quick commerce integrations, particularly for mid and bottom-funnel conversions. This convergence of media and commerce is redefining how ROI is measured, shifting the focus from reach and impressions to actual sales and conversion metrics.
The risk factor
Anticipating that early summers may present both opportunities and risks, a delayed or weak heatwave can lead to unsold inventory, reduced demand, and cutbacks in advertising spending.
Hingorani notes, “If the heat doesn’t go as per plan, advertisers will curtail campaigns. You have to look at your P&L and expected sales.” This uncertainty is forcing brands to build flexibility into their plans, allowing them to scale up or down based on real-time conditions. At the same time, committed spending on properties like IPL limits this flexibility, creating a delicate balancing act between fixed and variable investments.
When the heat cools and costs rise
According to media reports, rains across North India and inflation linked to the West Asia war have, over the past two weeks, reversed the robust early summer sales that beverage, air-conditioner, and refrigerator makers had been witnessing. This emerging volatility is forcing brands to recalibrate not just demand expectations but also cost structures and marketing strategies in real time.
Explaining the macro pressure, Raja Chakraborty, CMO, Continental Coffee, says “Global geopolitical tensions are beginning to ripple into summer marketing strategies, primarily through rising input costs. The war has increased pressure on petroleum by-products, which are key components in packaging, logistics, and production. This, in turn, is driving up manufacturing expenses and tightening gross margins.” He adds, “As a result, brands are likely to adopt a more cautious approach to marketing spends in Q1, prioritising efficiency over aggressive expansion. This could translate into sharper media planning, a shift towards performance-driven campaigns, and tighter ROI tracking. While consumer demand during summer remains strong, marketers will need to balance visibility with cost control, ensuring that every rupee spent delivers measurable impact amid an uncertain macroeconomic environment.”
Priyanka Verma, CMO, Danone India, said “Global uncertainty is making growth more uneven, even in a resilient market like India. It is fundamentally reshaping consumer behaviour. For brands, this means marketing can no longer rely on scale alone; it has to work harder on relevance, precision targeting, and demonstrating tangible value at every price point.”
A structural shift, not a temporary blip
Despite the challenges, most industry players agree that the shift toward advanced and more flexible summer marketing is here to stay. After three consecutive years of early heat onset, brands are beginning to institutionalise these changes. Sharma confirms, “We are now structurally building earlier activations into our core marketing calendar, while maintaining flexibility to recalibrate based on real-time demand signals.”
Similarly, Summercool sees early planning becoming the norm: “This shift toward early seasonal planning will increasingly become standard as climate patterns continue to evolve,” says Gupta. However, not everyone sees this shift as uniform across the country.
Pratik Shetty, VP, Marketing, Flipkart, offers a more measured view: “Summer typically picks up at different times across the country. In the south, it begins towards the end of February, while in the north, the uptick is usually seen by mid-March. This year has followed a similar pattern. Accordingly, we start earlier in the south, with campaigns going live in February, and then roll out across the rest of India by the second or third week of March. From a marketing standpoint, we haven’t seen any significant deviation from this timeline. It continues to operate within a fairly consistent window.” The lines between seasons have blurred. Marketing is no longer about planning for months. It is about planning for moments. And in a world where summer refuses to wait, the brands that move smartly will be the ones that stay cool under pressure.
