Households across the UK face balmy spring weather, with temperatures peaking at 25C today, Friday, May 1, according to the Met Office. Saturday brings slightly cooler highs of 23C in London, yet it will feel 2C warmer due to reduced cloud cover.
Residents should keep windows, curtains, and blinds closed until Sunday to maintain cooler indoor spaces as the heat persists. This prevents hot air from entering, making it easier to manage temperatures when conditions ease.
Ideal Room Temperatures for Vulnerable Groups
NHS guidelines recommend keeping rooms for babies and young children between 16C and 20C. When outdoor temperatures exceed this range, preserving comfortable indoor levels becomes challenging, especially in homes insulated for winter rather than summer heat.
Effective Strategies to Cool Your Home
UK properties, particularly in England and Wales, trap heat effectively during prolonged sunshine. Experts advise closing windows and coverings during peak sun exposure, opening shaded-side windows for ventilation, and airing out fully in the evening with cooler night air.
OVO Energy guidance emphasizes: “Tempting as it is to fling open the windows at the first sign of summer, it’s not actually the best idea. To keep your house cool, you need to keep the hot air out. This means keeping windows closed during the day – particularly south-facing windows. Keep curtains, blinds and windows shut when the sun is shining directly on them, and when you’re out. Try opening windows on the most shaded side of your home, to avoid sunlight and hot air getting in.”
Smart Window Management Over Common Myths
Heating specialists at BOXT warn that popular tactics like using fans or opening all windows can backfire. Adam Knight, Lead Engineer at BOXT, states: “Getting rid of unwanted heat in your home can be difficult in the summer months, especially when most UK properties are built to retain heat. While grabbing a fan or opening up all your windows are often mentioned as effective ways to cool your home, these methods may not result in the desired results.”
He adds: “When temperatures are particularly warm, opening up all your windows will let more hot air into your home, heating up your home and making you feel warmer. Instead of opening all your windows, it is much better to strategically open windows to create cross breezes throughout the day and open your windows during the night to let cooler air in.”
