Intense heat and low precipitation: IPMA records hottest September since 1931

The Portuguese Sea and Atmosphere Institute (IPMA) reported that September 2026 was the hottest September in mainland Portugal since 1931, with average temperatures 2.91°C above the 1991-2020 reference period. The month was marked by two heatwaves—one affecting the interior North from September 2nd to 7th, and a widespread second wave from September 18th to 27th—and was the fifth driest September since 2000, with rainfall reaching only 30% of normal levels.

Why it matters

While this is historical climate data, the record heat and lack of rainfall highlight ongoing drought conditions that can impact water usage restrictions and wildfire risk in the coming months.
