February 2026 in mainland Portugal was classified as very warm and extremely wet.

The mean air temperature reached 11.66 °C, 1.79 °C above the 1991–2020 climatological average, making it the 7th warmest February on record. The mean maximum temperature was 15.62 °C, about 0.91 °C above normal, while the mean minimum temperature reached 7.70 °C, corresponding to an anomaly of +2.67 °C relative to the climatological value.

Regarding precipitation, the month ranked as the 5th wettest since records began and the wettest in the last 47 years. Across much of the country, monthly totals reached three to four times the 1991–2020 average, exceeding five times the normal value in some locations, including Mora, Barreiro (Lavradio) and Alvalade do Sado.

During the first half of the month, intense rainfall was associated with the continued passage of successive low-pressure systems, accompanied by the transport of large amounts of moisture in the form of atmospheric rivers. Notable systems included Leonardo and Marta (4–7 February) and the frontal systems associated with Nils and Oriana (10–13 February), which contributed to persistent precipitation episodes.

As a consequence, the 2025/2026 hydrological year, by 28 February 2026, had accumulated 924 mm of precipitation, corresponding to around 1.8 times the average value, making it the wettest in the last 30 years and the 6th wettest since 1931.

This situation was also reflected in the high soil moisture content, with values between 60% and 100% across all municipalities. In several areas of the North, the central interior and the interior of Alto Alentejo, soils were already saturated, while in north-eastern Trás-os-Montes they were approaching supersaturation conditions.
