The UK experienced its warmest day of the year twice over the weekend, with temperatures nearing 20°C in some areas, according to the Met Office.

On Sunday, Crosby in Merseyside recorded a high of 19.7°C, surpassing Saturday’s peak of 19.1°C in Cumbria. The unusually warm conditions made parts of the UK hotter than popular holiday destinations such as the Balearic Islands, Spain’s Costa del Sol, and Italy’s Amalfi Coast.

Met Office meteorologist Craig Snell noted that the warmth was widespread across both eastern and western regions, with Scotland and Northern Ireland also enjoying pleasant weather. He confirmed that Sunday marked the warmest day of 2025 so far.

However, temperatures are expected to gradually drop throughout the week, accompanied by spells of rain.

Snell explained that while the south might retain milder conditions on Monday, reaching around 17°C or 18°C under cloudier skies, the north will experience a noticeable cooldown with patchy rain spreading southward.

By Tuesday, cooler temperatures will be felt nationwide and are likely to persist for most of the week. Northern and eastern regions can expect scattered showers, with temperatures ranging from 6°C to 8°C in the north and 8°C to 9°C in the south.

Snell added that midweek temperatures would remain in single figures, making for a noticeably colder spell compared to the weekend. While there will still be plenty of dry periods, a persistent breeze will keep temperatures low.

The cooler trend is expected to continue from Friday into Saturday before temperatures begin to rise slightly heading into the following weekend.

Last year was the 11th time since the 1960s that UK temperatures reached 34.8°C, with six of those instances occurring in the past decade.
