September Weather in Cabo Verde
Is September Right for You?
Advantages
- September sits between the summer peak and winter trade-winds, so you get glassy morning seas perfect for swimming with sea turtles around Santa Maria pier - something locals do daily but tourists miss because they assume it's 'off-season'
- The harmattan dust that blankets Cape Verde from December to March hasn't arrived yet, meaning the volcanic peaks of Fogo and Santo Antão photograph in crisp detail against deep blue skies - landscape photographers plan entire trips around this window
- Hotel rates on Sal drop 30-40% after August but the water temperature stays at 27°C (81°F) - you get peak-season ocean conditions at shoulder-season prices
- This is when the tuna fishing fleet returns to Mindelo harbor at dawn - the docks come alive with mackerel-scented chaos as crews unload 200-kilo bluefin while musicians play morna songs that echo off the warehouse walls
Considerations
- The Atlantic gets restless by mid-September - boat operators on São Vicente cancel 40% of excursions to Santo Antão when swells exceed 2 meters (6.5 feet), so island-hopping plans need built-in flexibility
- September marks the tail of Cape Verde's 'rainy' season (though 'rainy' here means brief afternoon showers), but when storms do hit Sal's flat landscape, flash floods can temporarily close the road between Santa Maria and Espargos for 2-3 hours
- Music festival season doesn't kick off until October, so Mindelo's famous live-music bars feel half-asleep - the Thursday night jam sessions at Café Musique where Cesária Évoria got discovered won't resume until tourist numbers pick up
Best Activities in September
Volcano crater hiking tours
September's 70% humidity feels brutal at sea level, but climb 1,200 meters (3,900 feet) into Fogo's crater and the temperature drops to a comfortable 18°C (64°F) - perfect for the 6-hour round-trip to the 2014 lava flow where the rock is still warm to touch. Morning starts (6 AM) beat both the heat and the afternoon clouds that obscure the crater views by 2 PM.
Sea turtle snorkeling excursions
The loggerhead turtles that nest on Sal's eastern beaches finish laying by September, meaning juveniles crowd the bay at Santa Maria pier for easy snorkeling - morning low tides (8-10 AM) offer 10-meter (33-foot) visibility when the usually rough Atlantic calms. Local fishermen know the exact spots where turtles feed on seagrass beds invisible from shore.
Moroccan quarter food walks
Mindelo's Rua de Lisboa transforms at dusk when September's cooling trade winds draw locals outdoors - the scent of grilled lobster mingles with cumin from tagine pots as Cape Verdean-Moroccan families serve dishes their grandparents brought from Rabat in the 1940s. The 7 PM timing catches vendors before they sell out of pastel de milho (corn cakes) that disappear by 8:30 PM.
Submerged shipwreck diving
September's 27°C (81°F) water temperature means 3mm wetsuits suffice for exploring Sal's deliberately-sunk Spanish cargo ship at 12 meters (39 feet) - the Atlantic's September clarity reveals the entire 40-meter (130-foot) vessel from the surface. The wreck teems with barracuda that circle divers like silver ghosts against the white-sand bottom.
Coffee plantation village tours
Santo Antão's 1,000-meter (3,300-foot) highlands harvest coffee through September - the smell of fresh beans drying on banana leaves drifts through Fontainhas' cobblestone streets where 19th-century Portuguese colonists built stone terraces. The 2-hour mule trek from Ponta do Sol climbs through cloud forest where temperature drops to 15°C (59°F) and hummingbirds feed on wild ginger.
September Events & Festivals
Festival de Mar
Sal's fishermen celebrate the end of tuna season with dawn-to-dusk beach parties at Santa Maria - families roast whole wahoo over driftwood fires while musicians play coladeira rhythms on overturned fishing boats. The informal nature means no tickets or schedules - just follow the smoke and music to the main beach around 4 PM when crews return with their final catches.
