Heatwaves (the second predicted so far, this year)

Here Comes the Heat: What You Need to Know About Heatwaves

After a grey and rainy spring, many of us welcome the sun with open arms. But when temperatures soar and the air feels heavy, it's no longer just a lovely summer's day--it's a heatwave.

What is a Heatwave?

A heatwave isn't just a hot day. It's a prolonged period of unusually high temperatures, often accompanied by humid conditions. In the UK, the Met Office defines a heatwave as three consecutive days where the daily maximum temperature meets or exceeds a specific threshold (which varies by region).

Why Should We Care?

While we might associate heatwaves with barbecues and beach trips, the reality can be more serious. High temperatures can affect health, particularly for the elderly, young children, and people with medical conditions. During the 2003 European heatwave, over 20,000 excess deaths were recorded across the continent. Heatwaves also stress our infrastructure, with transport delays, increased electricity demand, and even melting roads.

Staying Cool and Safe

Here are a few tips to help you keep your cool:

• Stay hydrated: Drink plenty of water, even if you don't feel thirsty.
• Avoid the sun during peak hours (11am-3pm): Seek shade and wear a wide-brimmed hat if you're out.
• Keep indoor spaces cool: Close curtains during the day, open windows at night, and use fans or damp cloths to cool your skin.
• Check on others: If you have elderly neighbours or friends who live alone, a quick check-in can make a big difference.

A Sign of the Times?

Experts say that as climate change continues, heatwaves are likely to become more frequent and intense. What was once a rare event might soon be a regular summer feature. This means adapting our homes, cities, and habits to cope with hotter, drier weather.
