North African Air Mass Brings Dust and Degrades Air Quality

Postal do Algarve4 September 2026 at 09:48

The Directorate-General for Health (DGS) issued an alert regarding the degradation of air quality in mainland Portugal, due to the presence of suspended dust from North Africa in the atmosphere. According to the Portuguese Institute of the Sea and the Atmosphere (IPMA), the phenomenon, which already occurred on Thursday, is expected to continue until Saturday.

An air mass from the North African deserts, carrying dust particles, is crossing mainland Portugal, affecting a large part of the national territory, especially the Centre and South regions. The situation is causing an increase in concentrations of inhalable particles of natural origin (PM10) in the air.

The DGS recommends that the most vulnerable population — children, elderly people, patients with chronic respiratory problems such as asthma, and cardiovascular patients — remain indoors with windows closed. The health authority advises that everyone should avoid prolonged exertion, limit outdoor physical activity, and avoid exposure to risk factors such as tobacco smoke.

Chronic patients should continue their ongoing medical treatments during this period. If symptoms worsen, the DGS recommends contacting the Saúde 24 Hotline (808 24 24 24) or seeking care at a health facility.

Weekend marked by strong instability: thunderstorms intensify in the North and Centre from Saturday afternoon

Mainland Portugal faces a weekend of strong atmospheric instability, with intense thunderstorms forecast for the North and Centre regions from Saturday afternoon (starting at 3pm), caused by the thermal contrast between extreme heat at the surface and a cold air mass at altitude, which enhances the formation of convective cells with heavy rainfall, lightning and possible hail. Simultaneously, 14 districts remain under yellow warning due to high temperatures, with maximums ranging between 27°C on the coast and 38°C in the Alentejo. However, the storm episode will be short-lived, with substantial improvement expected by Sunday, when the sky will clear and temperatures will drop generally, especially on the coastal strip.

The ECMWF model maps forecast an atmospheric blocking trend for the second half of September

The European ECMWF model maps predict an atmospheric blocking pattern in the North Atlantic for the second half of September, with a higher probability of the Atlantic Ridge regime occurring. This blocking could close the Atlantic to storms, allowing high pressures to dominate much of the ocean. In Portugal, this configuration should translate into more stable, dry weather and above-average temperatures for the season.
