UK weather: Hottest day of the year so far as temperatures hit 28.6C

The UK has recorded its hottest day of the year so far, with London's Heathrow Airport hitting 28.6C (83.48F).

The previous high was 28.3C (83F) in Northolt, west London, on 2 June.

The Met Office has warned people to be prepared when heading out and about due to high UV and pollen levels across much of England and Wales.

It is forecast to stay hot for the next few days before thunderstorms move in across England and temperatures become cooler.

Yellow weather warnings are in place for the eastern half of Wales and much of England from Wednesday until Friday, with the Met Office saying there is potential for travel disruption and flooding.

Meteorologist Dan Stroud said: "We're likely to become increasingly changeable towards the weekend.

"There is still the potential for some more settled spells and some warm weather is possible later in the month, but it is generally turning more changeable from this weekend".

Football fans cheering on Scotland north of the border had much cooler conditions.

While there was a high of 17C (62.6F) in Aberdeen, the temperature was a few degrees cooler still in Glasgow.

The city, where Scotland kicked off their Euro 2020 campaign against the Czech Republic at Hampden Park, reached only about 14C (57.2F).

Northern Ireland saw a high of 17C (62.6F) on Monday while Wales enjoyed a warm 24.4C (75.92F).

The Met Office had predicted Sunday would be the warmest day of the year but temperatures fell just shy, hitting 28C (82.4F) at Heathrow and St James's Park in London.
