The heat wave in Europe in August 2025 is expected to last through mid-August, with intense heat and high temperatures persisting for several more days. The heat dome causing the heat wave will remain strong and expand across Western, Central, and Eastern Europe until at least mid-August. Temperatures are forecast to reach the low 40s °C in several countries, with the heatwave potentially extending even longer in some areas. This long-lasting heat wave is causing severe drought conditions and increasing wildfire risks in affected regions.
In the United States, a significant heat wave in central and eastern regions has been expected to persist well into the following week from late June, with daily highs in the 90s and oppressive humidity.
Overall, heat waves like these typically last from several days up to two weeks or more, and this particular European heat wave is anticipated to continue into at least the middle of August 2025.
Thus, the current heat wave is expected to last at least until mid-August 2025, with possible variations based on region and evolving weather patterns.
