Heavy rain, thunderstorms and dust: bad weather on this day comes with temperature drops in these regions

Postal do Algarve6 September 2026 at 10:20

The weather conditions will change this Sunday in several regions of the country, after days of intense heat. The Portuguese Institute for the Sea and the Atmosphere (IPMA) forecasts a drop in temperatures on the mainland, especially in the North and Centre, in the Porto region and on the coast. In Greater Lisbon, the decrease will be smaller. Suspended dust will continue to be present in mainland Portugal, including in the Lisbon and Porto regions.

In the Azores, the scenario will be more adverse. IPMA issued a yellow warning for the Western Group due to the possibility of heavy rain or strong showers accompanied by thunderstorms. Rain is expected, sometimes heavy during the early morning and beginning of the morning, returning during the night, with wind that may have gusts up to 50 km/h. In the Central and Eastern Groups, rain is expected during the early morning and morning, followed by showers.

On the mainland, Sunday should be marked by few clouds or clear skies, although the North and Centre coast may have periods of greater cloudiness, with the possibility of mist or fog during the morning. The wind will generally be light from the west quadrant, becoming temporarily moderate on the western coastal strip and in the highlands.

In Madeira, the weather will be calmer, with periods of very cloudy skies but with good clear spells on the southern slope. In the Funchal region, the sky should remain generally few clouds and the wind will be light.
