The monsoon is finally drenching Mumbai and other Indian cities, bringing relief from months of relentless heat. Across the country, food delivery apps are pushing hot chai and pakoras combo, ride-hailing platforms are reminding consumers to ‘beat the rain’, and fashion brands are promoting waterproof footwear. Brands are responding to changing skies as quickly as weather apps do.
But the memory of this year’s scorching summer still lingers—on grocery receipts and shopping carts.
Before the clouds rolled in, much of India was battling temperatures above 40 degrees Celsius, with parts of the northern plains and central India continuing to experience intense heat even as the monsoon advanced elsewhere. The prolonged summer quietly reshaped the way people shopped, snacked and spent.
For marketers, this unpredictability has created a new reality—the weather has become a media trigger. Whether it is a sudden downpour driving umbrella sales or a 43 degrees Celsius afternoon prompting consumers to order electrolyte drinks, portable fans or air conditioners on quick-commerce platforms, brands are learning to respond promptly to temperature changes.
Weather is emerging as one of retail’s most powerful demand signals, shaping not only what people buy but also the media they consume.
Jolene Fernandes Solanki, Chief Operating Officer, Madison Media elaborates, “Any significant weather event influences consumer behaviour and, in turn, media consumption patterns. As India experienced prolonged periods of extreme heat across many regions, it led to reduced mobility, more indoor time, increased device usage, and greater focus on immediate comfort needs such as hydration, cooling, convenience and delivery.”
As a result of this, she highlights, engagement with mobile, OTT and CTV, social media and e-commerce platforms would have increased, while outdoor activities and certain retail visits may have declined during peak heat hours. “Weather change does not just change where consumers are, it changes what they are thinking about and what needs they are prioritising.”
Every summer, for example, India experiences predictable spikes in categories like beverages, ice-cream and air conditioners. But as heatwaves become more intense and prolonged, the impact extends far beyond seasonal purchases. Higher temperatures change consumption occasions, accelerate impulse buying, influence where consumers shop and even alter how brands communicate.
Highlighting what consumers prioritised during extreme heat, a Flipkart spokesperson says, “As summer peaked this year, Flipkart Minutes saw a significant surge in consumer demand for summer essentials. There were spikes in categories such as hand fans (over 23x), umbrellas (10x), and refreshments like watermelon (7x), lassi (5x), buttermilk (3x), and juices (3x). In the personal care segment, Deos & Talc demand doubled (2x).” Together, these trends did not just reflect demand, but a deeper consumer shift towards comfort and convenience.
Similarly, during the monsoon, brands are looking beyond the obvious surge in demand for umbrellas and raincoats to understand how the season shapes consumer behaviour and emotions. Instead of simply selling rain-related products, they're tailoring their messaging to real-life moments—whether it is instant help apps acknowledging the frustration of househelps being unable to make it to work due to heavy rainfall, or streaming platforms curating playlists and watchlists for cozy weekends indoors. The weather acts as a cue for more relevant, empathetic communication.
As climate patterns become increasingly unpredictable, marketers are also recognising that weather is a real-time driver of commerce, and tailoring their brand messaging accordingly, signifying a broader shift towards contextual marketing. Prachal Joshie, Associate Creative Director, Wife adds, “Brands are increasingly moving from seasonal storytelling to problem-solving. During periods of extreme heat, we saw communication focus on comfort, convenience, hydration and relief rather than simply celebrating the season. I also see a lot of real-time temperature and location data being used to trigger contextual messaging, whether that is promoting certain products and offers, or serving creatives that are elevant to what consumers are experiencing in that moment.”
Janhavi Iyer, Vice President, Brand Communications, Gozoop Creative clarifies that this is not new, but it has gotten sharper. “Categories such as beverages, air conditioners and personal care have always followed the mercury. What has changed is the sophistication. Programmatic DOOH can now auto-trigger a cold drink ad, the moment temperatures cross a threshold, in a specific city, at a specific hour. Context has become a creative strategy. The infrastructure in India is still maturing, but the early movers are already seeing the returns,” she says.
Brands such as Coca Cola, for whom summer remains a defining season, are leveraging this insight. Greishma Singh, Vice President, Marketing, Coca-Cola India and Southwest Asia shares, “We have developed a more granular understanding of the different ways summer comes to life for our consumers, and AI now enables our brands to show up with far more contextually nuanced content. Our Sprite campaign, for instance, played on the variations between humid (chip‑chip) heat and dry heat. Through weather‑linked media buying and dynamic content, consumers now see creatives that most closely reflect the summer heat moments they are experiencing. Just as critical is ensuring our portfolio shows up when those moments happen.”
Marketers now respond to real-time weather patterns and devise strategies where weather data, location intelligence and consumer insights work together to determine not just what message consumers see, but when and where they see it. “Weather-triggered marketing is rapidly moving from an innovation-led tactic to a mainstream capability. Brands integrate weather APIs to trigger dynamic creatives, push notifications and location-specific offers,” Solanki says, further highlighting that the industry is gradually evolving from audience-based targeting to moment-based targeting. “As climate volatility increases, weather APIs are becoming an increasingly important data layer for delivering the right message, in the right location, at the right moment.”
Take, for example, Flipkart’s collaboration with Inshorts Group for a weather-triggered advertising campaign during the brand’s ‘Super Cooling Days’. The campaign used a 'Heat Trigger Weather Widget' that displayed offers on AC brands when temperatures exceeded 32 degrees Celsius. Or take quick commerce apps such as Zepto and Zomato that push rainy day messaging as soon as the first raindrops arrive.
This evolution is especially significant in India, where climatic diversity means consumer demand can vary dramatically across regions. Solanki says, “The strategic shift is from asking ‘who is the consumer’ to asking ‘what is the consumer experiencing right now’. Weather becomes a powerful hyperlocal signal that helps brands deliver more relevant communication, improve media efficiency and capture demand as it emerges.”
However, she advises to use hyperlocal targeting selectively when weather variation creates a meaningful difference in consumer intent or demand, not simply because the capability exists. This ensures brands benefit from relevance without sacrificing reach and efficiency.
On the other hand, Iyer maintains that the hyperlocal aspect exists even beyond weather-triggered messaging. “Summer is a convenient headline, but hyperlocal was already coming, driven by fragmentation, rising Tier-II and Tier-III purchasing power, and a growing need for brand relevance in a country that is really many markets wearing one name. That said, summer (and weather, in general) does sharpen the case. A 48°C Rajasthan summer and a humid Chennai one aren't the same consumer experience, or the same brief. Geography is strategy,” she says.
Even as monsoon showers cool much of the country, they reinforce the same lesson brands learnt during summer i.e., consumers don’t just shop according to the season anymore. They shop according to the weather. And for marketers, the forecast has become just as important as the consumer profile.
