The Met Office has declared 1 July as UK’s hottest July day in almost 10 years as the mercury reached 36.7C at Heathrow, a suburb of west London. It breaks the previous record of 36.5C set in Wisley Surrey on July 19, 2006.
The mini heatwave had been predicted for the start of July but its intensity triggered a level 3 alert for those vulnerable to excessive heat. Temperatures nudged over 30 Celsius in many parts of west London and the rest of the southeast. Wimbledon had its hottest day ever and Kew Gardens recorded 35.7 C. Temperatures will however drop slightly tomorrow before warming up again on Friday.

The Met Office attributed the unusual temperatures to tropical continental airmass across mainland Europe. Temperatures across Iberia and France have already reached the low 40 °C, with Paris expected to hit 40°C today.

Chief Meteorologist, Steve Willington said: “Both Tuesday and Wednesday nights are expected to be warm and humid temperatures remaining in the high teens in many places, possibly low 20s Celsius in parts of southeast England.
“The very warm air means there is a risk of us seeing thunderstorms on Wednesday or Thursday but the exact timing and location of those storms, if they happen, is uncertain at the moment. Check our five day forecast for the latest weather information”.

Most areas in the UK are forecast to see warmer tempartures again on Friday although it may well be cloudy at times with a risk of rain spreading from the south by the evening. While many people enjoy hot weather, high temperatures can be dangerous.
Dr Paul Cosford, director for health protection at Public Health England (PHE), said: “Older people and those with long-term illnesses are particularly vulnerable to the effects of very hot weather, so it’s important to look out for them, help them stay hydrated with plenty of cool drinks, and keep indoor areas as cool as possible.
“Try to keep bedroom and living spaces cool, by closing the curtains on windows that receive the sun and open your windows at cooler times of the day and overnight. A trip to a park where there’s lots of shade or a public building that is air conditioned, may help offer some relief from the heat for vulnerable people.”
