This upcoming bank holiday weekend (Friday 22-Monday 25 May) is set to be “very warm” with “plenty of sunshine,” the Met Office’s current forecast reads.
Per the BBC, some parts of the UK will see the mercury rise to 28°C on Thursday and Friday.
Though very high temperatures (hotter than the hottest day of the year so far, which was 26.6°C), those don’t necessarily mean we’ll be in an official heatwave.

Here’s where temperatures are expected to soar, what makes a heatwave a heatwave, and how long the conditions are expected to last.
Where is it expected to reach 31°C in the UK?
As of time of writing, The Met has forecast 28°C in the South-East, including London, on Saturday, 23 May, with temperatures reaching as high as 30°C on Sunday, 24 May.
And on Monday, the South-East (including London) will see a scorching 31°C, the Met’s interactive forecast map currently reads.
