The current major heat wave in parts of Europe, notably centered in Western and Central Europe, has been ongoing through mid-August 2025. According to recent meteorological updates, the peak of this heat dome and extreme heat will continue with temperatures 8-10°C above average at least until the third week of August (around August 21). The heat wave is expected to start easing after this period with cooler conditions likely following the heat dome's shift north and east.
For example, in the Netherlands, the national heatwave plan became inactive from August 15, indicating an official end to alert status though heat remains elevated. Spain experienced a heatwave that ended on August 18 followed by cooler-than-normal temperatures.
In summary, the intense heat wave in Europe is very likely to continue through the third week of August 2025 , with signs of abating by the end of August. Exact local conditions may vary, but the major heat dome blocking pattern is expected to weaken after August 21, bringing relief from extreme heat.
