dataClima
Dataclima is an interactive digital platform that provides access to modeled and observed climate indicators for the Portugal mainland and island regions. The modeled climate indicators are made available since 1981, for the various territorial units and aims to support the most relevant activity sectors.
March 2026
March 2026 in Mainland Portugal was classified as warm and dry.
The mean air temperature reached 12.99°C, +0.62°C above the 1991–2020 climatological average, making it the 5th warmest March since 2000. The mean maximum temperature was 18.42°C, around +0.85°C above normal, while the mean minimum temperature was 7.57°C, corresponding to a deviation of +0.39°C from the climatological value.
In terms of precipitation, the month was the 8th driest since 2000, with a total of 42.1 mm, below the 1991–2020 normal, corresponding to 54% of average. In the Northern region, Central Portugal and in Alto Alentejo region, rainfall was less than half of the normal March value.
Soil water content decreased significantly due to the warm and dry conditions observed in March. Soil moisture values below 60% were recorded across much of the territory, dropping below 40% in some municipalities in the districts of Leiria, Santarém and Beja.

Exceptionally wet period between November 2025 and February 2026
Between November 2025 and February 2026, mainland Portugal experienced one of the rainiest periods of the last decades, ranking as the 6th wettest period since 1931 and the wettest since 1996. The 2025/26 hydrological year recorded values around 2x above normal in most river basins, with several regions already approaching the average annual total.
February 2026 was particularly anomalous in terms of precipitation, ranking as the wettest Fabruary in 47 years, with rainfall ranging from 300% to 400% of the average across much of the country.
This situation resulted from the persistence of westerly circulation and the southward displacement of the Azores High, which favoured a “train of storms” moving towards the mainland. Several successive depressions, including Storms Leonardo and Joseph, as well as Storm Kristin, which intensified through explosive cyclogenesis, producing gusts exceeding 150 km/h, caused persistent rainfall, floods, inundations, and landslides in various regions of the country.
