A new record was set for the hottest start of all May recorded Thursday, with temperatures reaching 29.3 ° C (84.7F) in London.
This top, which was recorded in Kew Gardens, broke the previous record of 27.4C (81.3F), which was established in Lossiemouth, Scotland in 1990, said the Met Office.
A large part of the United Kingdom rushed into the heat well above the average for the period of the year, although the conditions are cooler in Scotland and Northern Ireland.
The hot time spell was triggered by a high pressure area which had become blocked in the United Kingdom, leading to a southeast southeast air flow providing hot conditions.
Thursday was also the hottest day of the year so far, beating the previous summit of 26.7 ° C recorded in Wisley, Surrey earlier this week.
Temperatures in London have climbed above several European cities, including Athens and Rome.
The capital was also warmer than Cairo (27C), Marrakech (27C) and Los Angeles (21C).
Although I do not know the same type of peaks as Thursday, temperatures are on the right track to stay high for many on Friday.
However, conditions should come back closer to seasonal averages throughout the holiday weekend.
Temperatures are expected to reach the low years in the twenties in the south of England, the summits reaching only the middle of adolescence further north and in Scotland.
What feeds this sunny spell?
When we see heat registers called into question in the United Kingdom, there is often an influence of air from Iberia or North Africa involved.
This is not the case this week – instead, we saw a large high pressure area seated across the United Kingdom.

High pressure is essentially an enormous area in the atmosphere where air descends towards the ground and warming when it goes to us, which occurred cumulatively over several days.
There are a number of other factors at stake that have contributed to this record day.
The high pressure zone also came with a clear and sunny sky, which helps warm the ground.
A lack of rain has left the ground very dry, which means that it can warm up more quickly.
To break this warming cycle, the United Kingdom will need strong winds, a change of direction of the wind or the arrival of clouds and rain.
Although it seems to remain dry for the vast majority of the United Kingdom throughout the holiday weekend, we expect to see these wind conditions change, which will lower temperatures.
