On Monday, Britons saw the highest temperature of the year so far – 24.5°C recorded in St James’s Park, London, and temperatures are expected to continue to rise throughout the week.
But which areas will experience the warmest temperatures on the hottest week of the year so far? Here, The i Paper looks at all you need to know.
Met Office meteorologist Jonathan Vautrey said temperatures are likely to surge to around 25°C in the South East and London on Tuesday and highs of 27°C are expected on Wednesday.
Where the hottest temperatures will be be seen this week
Mr Vautrey said: “That corridor between the two cities could well see some of the top temperatures over the course of this hot spell. So it is quite a noticeable hot spell.”
He added Monday’s highest temperature “is a little bit of a moot point” because it will be surpasses ”essentially every day as we head towards Thursday” which is ”likely to be the peak of those temperatures”.
Will April’s record temperatures be broken?
The monthly records for April – 29.4°C and May’s record at 32.8°C are unlikely to be broken this week, according to Mr Vautrey.
What precautions should be taken when outside?
Warnings were issued over high levels of pollen and ultraviolet (UV) rays as the UK entered its warmest week of the year so far.
Prolonged exposure to UV rays, emitted by the sun, can lead to sunburn and an increased risk of skin cancer.

“It can lead to water inhalation and, in the worst cases, drowning. Be particularly careful near the water’s edge, it’s easy to slip and fall unexpectedly.
In the first quarter of 2025, LFB crews responded to 160 water-related incidents, averaging more than 13 per week compared with fewer than 11 a week in 2024, the LFB said.
