With Barnes forecast to reach 31°C again today — partly cloudy, UV index 8 and just a 5% chance of rain — Richmond upon Thames has issued updated guidance on staying safe during prolonged hot weather. Met Office forecast for Barnes, 10 July.
Anyone can feel unwell in the heat, but the council highlights that older adults, children under five, pregnant women, people with underlying health conditions, and those living alone face a higher risk. People working or exercising outdoors are also more vulnerable than they might expect.
Practical steps include keeping curtains or blinds closed on south-facing windows during the day, drinking water regularly even if you don't feel thirsty, and checking in on elderly or isolated neighbours — a simple knock or phone call can make a real difference during a sustained hot spell.
Homes most at risk of overheating include top-floor flats, properties with large sun-facing windows, and highly insulated buildings. If your home becomes uncomfortably hot overnight, the council advises opening windows once outside temperatures drop in the evening.
