BRITAIN is set to face its warmest night on record as temperatures are set to remain high overnight.

The Met Office is warning that temperatures through this evening and into Tuesday are set to remain in the low to mid-20s in isolated places and could break a 32-year-long record.

The current hottest overnight temperature was 23.9C, recorded in Brighton in August 1990.

It comes as Wales provisionally recorded its hottest day on record, with the mercury climbing to 37.1C in Hawarden in Flintshire, beating the previous record by almost two degrees.

Tomorrow could see Britain record its hottest ever temperature, with highs of 41C forecast for parts of central and southern England.

Met Office meteorologist Luke Miall said: “I’ve been a qualified meteorologist for ten years and telling people about 41C in the UK doesn’t seem real.

“It’s crazy how we are talking about these sorts of values, I’ve never seen the models coming up with these values.

“It’s been quite an eye-opener to climate change with all these temperatures in UK.”

Hot air from Europe is contributing to the extreme heat in Britain, with a searing heatwave baking much of the continent, fuelling fierce heatwaves in France and Spain.

The UK Health Security Agency has issued a Level 4 heat-health alert, described as an “emergency”.

Train services will see further disruption tomorrow, with trains running at reduced speeds to protect rails and with some routes seeing reduced services.

Climate change, which has pushed up global temperatures by 1.2C on pre-industrial levels, is making heatwaves longer, more intense and more likely.

Experts have warned of the need to adapt homes, cities and infrastructure in the UK for a future of more intense summer heat.
