A UK heatwave is forecast to bring temperatures above 30C across several regions, with tropical nights creating challenging indoor conditions. Energy experts recommend placing a bowl of cold water or ice on a windowsill near an open window to cool rooms by drawing heat from the air and circulating cooler vapour. Using a fan with the ice bowl enhances the effect at a far lower cost than air conditioning. The method is supported by LEAP Energy Advice and British Gas as an inexpensive way to manage indoor temperatures during extreme heat.
