Paris Hits Unusual 26 Degrees in April 2025

Extreme temperature anomalies in Europe are increasingly impacting urban infrastructure and public services, as evidenced by record-breaking heat recorded in Paris and across the continent during 2025. On April 5, 2025, Paris recorded a maximum temperature of 25.9°C, the warmest temperature ever recorded for that specific date.

This temperature was recorded at the Montsouris station, marking it as one of the four earliest occurrences of temperatures exceeding 25°C since 1950. In the broader region, Mussy-Sur-Seine recorded a higher temperature of 26.9°C on the same date.

Impact on Tourism and Public Infrastructure

The trend of unseasonably high temperatures progressed into a series of severe heatwaves from April to September 2025, causing significant operational disruptions for major European landmarks and educational institutions.

By July 1, 2025, the extreme heat forced the closure of the summit of the Eiffel Tower in Paris to visitors. Simultaneously, hundreds of French schools were closed on a Tuesday in June 2025 as the region experienced a major heatwave.

Forecasts during this period indicated that temperatures in Paris could reach 104 degrees Fahrenheit (40 degrees Celsius), while unusually high temperatures persisted in Belgium and the Netherlands.

Continental Scale and Economic Consequences

The 2025 heatwaves affected a wide array of European nations, including France, Germany, Spain, Italy, the United Kingdom and several Eastern European countries. The environmental and human cost was substantial, with an estimated 16,500 deaths attributed to climate change during the summer by September 18, 2025.

Specific death tolls reported include:

• Italy: 4,597 deaths
• France: 2,842 deaths
• Spain: 2,841 deaths
• Germany: 1,477 deaths
• United Kingdom: 1,147 deaths

Beyond the loss of life, the heatwaves fueled numerous wildfires across Europe, resulting in damage to property, ecosystems, and air quality.

Regional Temperature Records

Several countries broke national and regional temperature records during the 2025 cycle. Portugal and Spain both broke national records for the maximum June temperature, with readings surpassing 46°C (115°F).

In Spain, the national weather agency announced in September 2025 that the summer—defined as the period between June 1 and August 31—was the hottest on record, with an average temperature of 24.2°C (75.6°F).

Barcelona experienced its hottest June in more than a century. The Fabra Observatory reported an average temperature for June 2025 of 78.8°F (26°C), breaking the previous record of 78.08°F (25.6°C) set in 2003. A single-day high of 100°F (37.8°C) was recorded in Barcelona on a Monday in June.

In Eastern Europe, Albania experienced unseasonably warm temperatures in mid-April 2025, with Tirana forecasted to reach 28°C (82°F). Later, on June 9, 2025, Tirana recorded a temperature of 37.6°C (99.7°F).

The peak temperature for the 2025 European heatwaves was recorded at 50.5°C (122.9°F) in Silopi, Turkey, on July 27, 2025.
