Weather in the second half of September in Portugal: here's what to expect from rain and temperatures until the end of the month

Meteored Portugal14 September 2026 at 07:03

The temperatures and precipitation in Portugal will show values deviating from the reference climatological normal in the last two weeks of September. This month has been hot, with temperatures above average in most of the country, and the last few days and coming hours will still record values close to 40°C in some locations, especially along the interior strip and in the south of the country.

From an atmospheric perspective, stability has dominated the scene due to the presence of an anticyclone that remains over the Portuguese geography, acting as a barrier that prevents the occurrence of precipitation. The dry and warm weather trend could continue in the coming weeks, although the forecast is not fully confirmed.

September is thus being characterized by typical summer meteorological conditions, with intense heat and absence of rain, raising the question of whether this trend will extend until the end of the month or if there will be significant changes in the weather pattern.

Why this matters

Readers in Portugal will face two more weeks of above-average heat, with temperatures that can reach 40°C in the interior and south of the country. The absence of rain will persist due to the anticyclone blocking low-pressure systems, potentially affecting outdoor activities, water consumption, and agricultural conditions.

Anti-rain dome in Portugal for 7 days: "there is an explanation"

Portugal should face seven days practically without rain, between September 14 and 21, despite the passage of deep depressions over the North Atlantic. This situation, described as an "anti-rain dome," results from a specific atmospheric configuration: an upper-level ridge extends from the subtropical Atlantic to the Iberian Peninsula, favoring the descent of air and atmospheric stability, which makes it difficult for clouds to form and for significant precipitation to occur across most of the territory.
