The weekly Weatherman email has been designed to help retailers "make the most of the profit opportunity when it comes to the bottled water category during hot weather spells ", according to Danone.
"Savvy retailers will already know the impact that weather has on their bottled water sales. Taking 14░C as a base, when the sun is shining and temperatures reach 20░C, sales will typically rise by 36% and when it reaches 25 ░C sales will increase by 78%. If the temperature tops 30 ░C bottled water sales will typically increase by a whopping 125%, making it imperative for retailers to keep an eye on the weather forecast," a spokesman said.
Trade communications manager Liz Forte added: "We always strongly recommend that retailers stock up when it becomes hot and sunny, but the Weatherman email service details exactly when that happens - and how much more water retailers can expect to sell as a result."
