We are only just past halfway through 2022. However, this year has already been extraordinary in many respects, one of which is the record breaking number of heatwaves we’ve seen so far across the world. For those interested, this Wikipedia page lists all the heatwaves in 2022 to date.
Impact on sales
A comparison of sales in the 12 weeks to 10 July 2022, to sales in the 12 weeks to 11 July 2021, shows mixed performance across grocery stores in the UK, with discounters gaining the most, due to consumers switching to them to minimise their grocery spend in light of soaring inflation.

However, despite current inflation rates, BRC-KPMG retail sales monitor for July 2022 showed that total sales increased by 2.3% during the month, bringing to an end three consecutive months of decline.
Ice cream, beer, water & barbecue ingredients sales benefitted the most from the heatwave, while sales of barbecue grills themselves rocketed during this time despite fire hazard warnings. Outdoor furniture sales also benefitted, as more people planned to spend time outdoors in August. Clothing retailers also benefitted during this time.
Gelato & ice cream brands and vendors benefitted all through Europe, as people consumed them in a bid to cool down.
US grocery sales, in the meantime, also benefitted from this, albeit in a different way. Online grocery sales saw the most increase at 17% vs prior year in July, as more consumers sought to avoid travelling outside during this time.

On the overall, US supermarkets benefitted from increased demand during this period, with Albertsons companies benefitting the least at 10% growth vs prior year.

However, some delayed impacts of these heatwaves are yet to come. Typically, for regions that have high humidity levels, heatwaves bring with them increased demand at a later date for anti mould and anti fungal products. Also, shampoo, conditioner, anti frizz hair products and shower gel sales increase following heatwaves as people use these more frequently during heatwaves than they usually do.
So how can you best prepare your store for these heatwaves?
Keep an eye on weather forecasts by reputable agencies. When a heatwave, storm, cold wave or any unusual weather event is expected, look at temperatures expected, humidity levels etc and consider how these, in combination, will impact human behaviour.
For instance, a heatwave is declared in the UK anytime the temperature rises above 25℃ or 26℃. When temperatures are between 26℃ & 32℃, people plan to and are likely to go out, and enjoy the warm weather outdoors. So sales of certain products like beer, wine, water, picnic essentials, barbecue ingredients etc are all likely to increase a few days ahead of these heatwaves. Sales of these products continue to stay elevated during the heatwave as some consumers maybe more impulse led than others. During this period, depending on humidity levels, sales of anti frizz hair products and brands may also increase.

However, when temperatures increase beyond 35℃, sales of these products may not increase as much, as some people may prefer staying indoors where it is cooler. Also, impulse sales will not be as high at stores, and may move to quick commerce channels, as more people want to avoid the heat outside.
When a heatwave is expected, looking at humidity and dust levels is important when considering what and how much to reorder as they impact demand for shampoos, conditioners, moisturisers, home cleaning products and laundry products.
Sound complex? That is because, it is
Impact of changes in weather can be difficult to predict when looking at things in isolation. So consider not just weather forecasts, but also the demographics of consumers around your store location. People from different countries behave differently when it comes to weather. So if your store is located in a cosmopolitan area, consider how people from different backgrounds may react differently to these changes.
