UK likely to temperatures approach 100F the next few days, with all-time records possible in central and eastern Europe this weekend

Jun 23, 2026

France’s national meteorological agency Meteo France reported that the nation’s average temperature today was the hottest ever recorded, as numerous sites in the country saw high temperatures at or above 100F (37.8C).

Many locations, particularly in western France, set their all-time record maximum temperature. Bordeaux (Paulin) reached an insane 44.6C (112F) per Meteociel and climatologist M. Herrera. Daily and monthly record high temperatures were common across much of western Europe. French Prime Minister Sébastien Lecornu reported that 40 people have died in country from drowning while attempting to cool off in lakes and rivers.

Unfortunately, this heatwave will only persist and gradually expand north and east through the remainder of the work week. England and Wales will see many locations reach high temperatures well above 90F the next few days with a few locations potentially reaching 100F. By this weekend, some relief will begin to spread into the continent from the west, but the extreme heat will also build east into central and eastern Europe with temperatures of 40C (104F) expected to overspread much of Germany, Poland and nearby countries.

The European model shows Berlin reaching 41C (106F) on Sunday, which would be a new all-time record high there. The heat across much of the continent is also being accompanied by unusual humidity which is making health concerns even greater. The humidity is also keeping morning low temperatures at record warm levels. The morning low in Berlin on Sunday is forecast to be 24.8C (77F), which would also be near an all-time record.

In the United States, hot temperatures with a few records have been building across the West the last few days — but by this weekend into next week an unusually strong area of high pressure aloft is expected to build across the eastern half of the country and bring increasing and potentially record heat to many areas. Humidity and overnight low temperatures will be elevated, resulting in extreme heat stress in many areas.

The upper level high pressure area will be developing downstream of an evolving trough of low pressure across the western United States. This weather pattern will result in increasing winds across much of the west. These winds coming after a period of hot and dry conditions and with extreme drought in many locations will result in a period of active to potentially extreme fire danger conditions for parts of the West in the coming week.

This is particularly concerning given that there has already been a significant increase in wildfire activity in the last several days, with numerous large wildfires now burning across the Great Basin and Southwest. In addition to the direct threat from wildfires, wildfire smoke will likely become an increasing issue across at least the western half of the country as fires expand and smoke is transported well downstream.
