A 30C heatwave that sparked the first health heat alert of the year is set to scorch north London this weekend.

The UK Health Security Agency (UKHSA) warning covers London and is in place from 9am tomorrow (Friday June 9) until Monday morning.

Parts of the country are predicted to be hotter than Marbella, Ibiza and Tenerife over the weekend as a plume of warm air moves in from the south.

There will likely be some impacts across the health and social care sector if forecast temperatures are reached, the UKHSA said, with over-65s and those with pre-existing health conditions most at risk.

Dr Agostinho Sousa from the UKHSA said: “In the coming days we are likely to experience our first sustained period of hot weather of the year so far, so it’s important that everyone ensures they keep hydrated and cool while enjoying the sun.”

The Met Office has also issued a yellow warning for thunderstorms on Saturday, stating that heavy rain and hail is likely in some places during the afternoon.

Dan Harris, deputy chief meteorologist at the Met Office, said: “Temperatures over the weekend could peak (at) around 30C in some parts of England and remain well above average overnight through the weekend.

“Coupled with the rise in temperatures is an increase in the likelihood of some potentially heavy and thundery showers, which could bring some localised disruption for some from late on Friday and into the weekend.”
