A strong North wind is coming bringing dust and cooler weather

Observador15 September 2026 at 16:25

Temperatures are dropping sharply across the country, bringing with them an air mass from the North that carries dust and lower quality air. The wind will blow with significant intensity in several regions, contributing to a cooler thermal sensation.

This meteorological change affects air quality, which should show lower levels of purity due to the presence of dust brought by the north wind. It is recommended that the population take precautions, especially people with respiratory problems.

However, this situation of cooler and windier weather will be temporary. An Azores anticyclone, favorably positioned, should return and bring back the heat in the coming days, reversing this downward temperature trend.

Why this matters

This weather event directly affects daily life for people across Portugal, as the strong winds and dust will impact outdoor activities, air quality, and health, particularly for those with respiratory conditions. The temperature drop will require wardrobe adjustments, while the forecast return of heat offers a glimpse of relief ahead.

Portugal contradicts European drought with dams at 77% and the Algarve is among the examples of recovery

Portuguese dams present an average storage of 77%, placing Portugal in a more favorable situation than various European Union countries, which face serious drought problems. The president of APA, Pimenta Machado, guaranteed that the country is well prepared for next year, thanks to the rainy winter that allowed the recovery of water reserves. The Algarve, a region particularly affected by water scarcity in recent years, is presented as a positive example of this recovery, with the Bravura reservoir reaching 99% capacity in May.
