How is air quality in Cape Verde in 2026?

North-east trades and surrounding ocean dilute local traffic and generator exhaust for most of the year. Praia has more cars and construction dust than a quiet Santo Antão ridge, yet the baseline still differs from large industrial metros: Living in Praia. Santa Maria and Mindelo weeks often feel clearer between events when the trades keep blowing: Living in Santa Maria and Living in Mindelo.

Saharan dust on East or East-Northeast flows creates dry haze that national climate documents call bruma seca. Peer-reviewed work on Cape Verde notes strong surface-level dust into Praia from about October through March, with hourly PM10 that can spike sharply during thick events. Tourism climate pages describe warm sandy Harmattan-style pulses that often clear within a day or so, though multi-day haze also happens. During thick events, sensitive groups should limit outdoor exertion: Healthcare costs and Outdoor recreation.

Keep a simple indoor plan: closed windows where cooling allows, extra water, and postponed ridge hikes when the horizon disappears. Dust can stack with warm sticky nights in late summer or with sharp winter trades: Summer heat, Dry season and Wind. UV still burns through thin haze: UV.

If asthma or other respiratory limits are a veto, treat dust season as seriously as rent when you pick an island. Sal’s open sand and Praia’s basin traffic feel different during the same plume: Best climate and Humidity.
