Further details

Following very warm weather on Sunday, very high temperatures, accompanied by high humidity, are expected on Monday and especially Tuesday and will likely bring widespread impacts to people and infrastructure. In addition to high daytime maxima, temperatures overnight will remain very warm, especially in larger urban areas.

Temperatures are likely to reach the low to mid-30s Celsius in places on Monday and into the mid-30s Celsius more widely on Tuesday. Some places, particularly in urban areas, may see temperatures remain above 20 Celsius overnight.

The very high temperatures are likely to continue across parts of central and southern Britain further on into next week, albeit with some uncertainty in the extent and magnitude of this heat.

Further details

During the heatwave expected to affect a large part of England and Wales this week, the highlighted area now looks increasingly likely to see a two to three day period where maximum temperatures in the shade exceed 37 Celsius, perhaps rising to 38 to 40 Celsius in some places. The heat will be accompanied by high humidity, exacerbating the potential for discomfort and health impacts, with very warm and humid night times also reducing the ability for people to recover overnight.

Significant disruption to daily life is likely and the public should take every effort to make precautions and adapt their daily routines where possible to cope with these levels of heat, which up to now have been extremely rare for the UK.
