London is due for a mini-heatwave on Friday, July 19, with weather maps turning bright red. According to WXCharts temperatures will reach 28.6C in the afternoon of Friday and the rest of the working week is going to be getting hotter and hotter until then.
There is no rain predicted throughout the working week either. Today (Wednesday, July 17) and Thursday (July 18) are also looking to be pretty warm.
Today London will see highs of 23.1C at 1pm and lows of 14.2 during the night. Thursday will be slightly hotter still with highs of 25.3 rolling in at 4pm and lows of 15.2 during the early morning.

Friday is the peak of this hot and sunny spell with baking highs of 28.6C due to come on at about 4pm. The lows will be 18.7 in the early morning. The nights will be fairly warm this week so it might be an idea to dig out that thinner duvet once again.
Sadly the mini heatwave is keeping very true to its name as it is predicted to gradually fall away over the weekend. Saturday, just one day after the peak, sees a significant reduction in temperature. The highs will be over just 21.9 at 7pm and lows will be 17.8 in the early hours.
Sunday does not seem much better with highs of 21.4 at 1pm and lows of 14.4 during the night.
What does the Met Office say?
The Met office backs up WXChart’s weather map, showing the working week to be getting hotter. However, they believe that the heatwave will not die off so suddenly over the weekend.
They say Friday itself will be even hotter with highs of 31C and lows of 19C. They agree that the hottest point will be at 4pm and predict there will be almost no cloud cover with just pure sunrays shining on the city. The lows will be during the early hours of the morning.
They warn that there is a significant level of UV radiation coming from all this sunny weather, particularly around 1 o’clock when there will be level 8 UV level which is very high. This means suncream is a necessity.
Today (Wednesday, July 17) is due to be pleasantly sunny too with highs of 25C and lows of 15C. The temperature will peak from 4pm until 6pm. Thankfully we have already had the coldest of it this morning. There is due to be partial cloud cover all day. There are also relatively high UV levels today with level 7 radiation during the morning.
Tomorrow (Thursday, July 18) will be slightly warmer, the Met Office agrees. Here there will be highs of 28C and lows of 19C. The temperature will be at its hottest from 4pm until 6pm, similarly to today’s forecast. The lows will be during the early morning.
Unlike WXCharts, the Met Office does not report the heatwave to die off so quickly over the weekend. They predict that Saturday will bring healthy highs of 28C and lows of 17C – much higher than WXCharts’ highs of 21.9. The hottest part of the day is again to be the later afternoon with the lows coming in the early morning.
Sunday will see a reduction in temperature but again no as drastic as WXCharts’ predictions. The Met Office say there will be highs of 24C and lows of 15C. Temperatures are due to fall through till next Wednesday when cloudy weather will resume, the Met Office say.
