London's 5th heatwave: 36C peak Thursday, rain Aug 20

London is set to endure its fifth heatwave of the summer, with temperatures forecast to reach a scorching 36C on Thursday, August 13. The Met Office and BBC Weather both predict a peak of 34C, but forecasters told the Guardian that temperatures could climb as high as 36C. A yellow heat health alert is currently in place, warning of risks to vulnerable people, and is expected to be extended if the heat persists.

Heatwave duration and peak days

The current heatwave began on August 9 and is expected to last until August 15, according to forecasters. The hottest day is likely to be Thursday, August 13, when the mercury could hit 36C in the capital. This follows a summer of relentless high temperatures, with parks and green spaces across London dried out and a hosepipe ban in effect.

Residents are advised to seek refuge in air-conditioned museums, book a spot at a lido, or indulge in ice cream to cope with the heat. The yellow heat health alert, which signifies a risk to vulnerable people, is in force until 9pm on August 11, but may be extended or escalated as the heat continues.

Rain forecast and impact

According to BBC Weather, the only rain expected in the next couple of weeks will be on Thursday, August 20. However, this forecast is subject to change. The prolonged dry spell has exacerbated the drought conditions, with the capital already under a hosepipe ban.
