In a stark testament to an accelerating climate crisis, France has officially recorded its hottest month in over a century. Météo-France confirmed on Tuesday, August 4, that July 2026 surpassed all previous records, etching a new and alarming benchmark in the nation’s meteorological history since measurements began in 1900.
The national average temperature soared to a blistering 24.9°C, eclipsing the tragic heatwave of August 2003 (24.8°C) and the previous July record set in 2006 (.4°C). This figure represents a staggering anomaly of +3.8°C above the 1991-2020 normals, a period already significantly warmed by human activity. This marks the second-highest monthly anomaly ever recorded, trailing only February 1990.
A Relentless Onslaught of Heatwaves
The historic month was forged by two distinct and punishing heatwaves. The first, stretching from July 4 to 19, was described by the forecaster as “remarkable for its duration,” becoming the third-longest heatwave ever to grip the country. A second wave began on July 28 and is still ongoing, offering no respite.
The peak of the heat was registered on July 12, with a 24-hour average national temperature of 28.1°C. This relentless heat has been a fixture since late spring, with July marking the fourth episode of extreme temperatures. Looking ahead, Météo-France’s climate trends for August through October indicate that hotter-than-normal conditions remain the “privileged” scenario, though this does not guarantee further heatwaves.
A Nation Parched: Record-Level Soil Drought
The extraordinary heat was compounded by a near-total absence of rain. July 2026 recorded a rainfall deficit of nearly 70%, making it the third-driest July on record and dramatically worsening the superficial soil drought that has plagued the country for two months. By the end of the month, soils were drier than during the same period in the historic drought years of 2022 and 2025, reaching levels equivalent to the all-time lows of August 2022.
This record parchedness has had severe consequences for agriculture and created a tinderbox environment for wildfires. The conditions fueled a devastating megafire in Gironde at the end of July, which ravaged thousands of hectares and destroyed homes. Rain was virtually absent north of the Seine, around Nantes, in Occitanie, and across the French Riviera and Corsica.
An “Overwhelming” Sun Aggravates the Crisis
Adding to the misery, an “overwhelming sun” dominated the country, with a national average sunshine excess of 35%. This ranks July 2026 as the second-sunniest July on record, just behind July 2022. Météo-France highlighted this as a critical “aggravating factor” for the drought, explaining that the combination of zero precipitation, intense solar radiation, and scorching temperatures dramatically accelerates soil drying and increases water demand from vegetation.
The cascade of shattered records—from peak temperatures to soil aridity—paints a clear picture of a climate system under duress, turning a summer month into a prolonged national emergency.
