Temperatures could reach record breaking highs this week as the country continues to bask in a summer heatwave.

The Met Office has warned of a possibility of all-time records being broken as temperatures are predicted to reach 38C in parts of the country tomorrow.

While the north west is expected to see figures reaching 35C, the south east of England id set to sizzle in temperatures of up to 39C.

The hottest day on record ever in Britain is 38.5C that was recorded in Faversham in August 2003.

The humid conditions are a result of warm air pushing its way up from the continent this week, the Met Office has said.

Tweeting today, senior meteorologist and BBC weatherman for Wales, Derek Brockway, said: "Hotter again tomorrow and humid with sunny spells and a few scattered heavy, thundery showers.

"Exceptionally hot in London tomorrow. 37 or 38°C would be a new UK record for July! Turning cooler and fresher on Friday with temps back to normal over the weekend. 22°C in Cardiff."

Temperatures are expected to return closer to normal throughout the weekend as more unsettled weather, with an increased chance of showers for many, is predicted.

The mercury hit 31C in Cardiff yesterday, beating the previous record for 2019 which was 30.2C and recorded on June 28 in Llanfairfechan.

However, it failed to beat the July record in Wales which was set in 2006 in Gogerddan, Ceredigion, when thermometers reached 34.6C.

Heatwaves are extreme weather events, but research shows with climate change, they are likely to become more common, perhaps occurring as regularly as every other year.

A Met Office study into the UK heatwave last summer showed that it was 30 times more likely to occur now than in 1750 because of the higher concentration of greenhouse gases in the atmosphere.

The Earth’s surface temperature has risen by 1°C since the pre-industrial period (1850-1900).

Bookmaker Coral is offering offs of 1-2 of a new temperature record being set.

John Hill, from the company, told the Mirror : "The betting suggests we are set for a record-breaking day in the UK with the previous high of 38.5C set to be broken.

"In what is certain to be sweltering conditions, the odds have been cut on 40C or higher being recorded, while we are being bombarded with bets on this being the hottest summer ever in the UK."
