The UK and central Europe are experiencing another extreme heatwave, with all-time records being broken in many places. Temperatures soared into the upper 30s and low 40s across the UK, Netherlands, France, Belgium, Germany, Italy, Switzerland and Spain on 24th July - and continued to rise. France (Châteauvillain) saw 42.1 °C, whilst Belgium (39.9 °C, Germany (40.5 °C), and the Netherlands (39.3 °C) all recorded their highest ever temperatures – a record that could today (25th July) be broken for the second time in two days. In the UK, yesterday saw a peak of 33.7 °C in Cavendish, Suffolk with 30 °C across much of the South East.

The heat is expected to peak today (25th July), with a larger area of the UK – including Scotland – seeing temperatures hitting 30 °C. There is also potential for the UK’s hottest ever temperature (39 °C) to be measured – the all-time high of 38.5 °C was recorded in August 2003.

Thunderstorms Triggered

Overnight on the 23rd - 24th July, large swathes of the UK experienced intense thunder and lightning moving up through Europe, with more than 40,000 strikes being recorded across the UK. Today’s heat could trigger further thunderstorms, with the Met Office issuing a yellow warning for large parts of England and Scotland, lasting from 15:00 BST today to 04:00 tomorrow.

Health Risks

There are very real risks to life during such heatwave events. The 2003 European heatwave killed more than 35,000 people during a two week period (many of these occurred in France). It is therefore important for everyone to understand how to cope during a heatwave, but especially vulnerable people; most of the deaths caused by such heatwaves are among the elderly, but it is noteworthy that more than 1,000 of the deaths during the 2003 heatwave were among people aged 35–64. Find out more about heat stress in our article >>

In May, Public Health England published a Heatwave Plan to raise awareness of the potential dangers to health from severe hot weather.

Climate Change

Blaming a single heatwave event on global warming is complicated, however it is possible to say that such extreme events are likely to happen more often, are hotter and are lasting longer due to human-induced climate change. Indeed, the five hottest European summers since 1500 have all occurred this century, and last year, a Met Office study concluded that heatwaves in the UK are lasting twice as long as they did 50 years ago.  France’s national weather agency has also said that the number of heatwaves in France has doubled in the past 34 years and this is expected to double again by 2050, while their intensity has also increased.
