The UK has seen one of its warmest April days on record, forecasters have said.

A temperature of 26.6C (79.9F) was recorded at Kew Gardens, southwest London, on Wednesday – making it the hottest day of 2026 so far, the Met Office said.

It was also the hottest day recorded in the first half of April since 1946.

Wednesday's temperature beat the 24.8C (76.64F) recorded in Mona on the island of Anglesey in Wales on Tuesday, which was the warmest 7 April on record.

It was also hotter than temperatures recorded in some popular holiday destinations, including Ibiza and Rome.

The current warm spell is "well above" the early April average of 12C to 15C (53.6F-59F), forecasters said.

In a post on social media, the Met Office said: "For context, temperatures above 26C are very uncommon in early April.

"Indeed, today has been the second warmest day on record during the first half of any April."

The warmth is due to southerly winds, but it will turn much cooler on Thursday as a more westerly wind develops behind a cold front.

Forecasters have also been warning people to be aware of high UV and pollen levels.

The Met Office said: "It's the peak of the tree pollen season and levels of ash and birch pollen will remain very high across parts of England and Wales through the rest of the week."

Many people have also been enjoying the weather for the school Easter holidays by heading to the coast.

Sky News weather producer Jo Robinson said: "This is likely to be the warmest early April spell since 2020.

"UV levels will be moderate - which may catch people out after the long winter, while the pollen count will be very high for most.

"On Thursday, temperatures will be much lower just about everywhere, but southeast England will hold onto the warmth with temperatures into the low twenties."

The Met Office said daytime temperatures could fall by around 10C between Wednesday and Thursday ahead of "more unsettled" conditions later in the week.

Despite the warm sunshine across many parts of England, there have been cooler conditions in Northern Ireland and northwest Scotland.

The Met Office said there could also be outbreaks of rain.
