São Vicente island, Cape Verde Weather: Best Time to Visit

São Vicente Weather: Wind, Seasons & Best Time to Visit

What the weather is like on São Vicente through the year, how the wind shapes the island, and the best months for your trip.

São Vicente is warm, dry, and sunny for most of the year, with very little rain. What changes most through the seasons isn't the temperature, which stays pleasant year-round, but the wind. Understanding when it blows, and where on the island it blows hardest, is the key to choosing when to come and where to swim.

At a Glance: Quick Overview

Climate: Dry and semi-arid, warm all year, with little rainfall.

Temperatures: Roughly 22°C in winter to around 30°C in late summer.

Windiest: Roughly January to April, with the strongest trade winds.

Calmest: Roughly May to July, the best overall window for beaches.

Rainiest: August and September, though rain is still limited.

Best for Carnival: February or March.

Section 1: The Climate in Brief

A dry island in the path of the trade winds.

Dry & Warm. São Vicente has a dry, semi-arid climate. Rain is scarce for most of the year, the landscape is volcanic and largely bare, and the sun shines on most days.

The Wind. The island sits in the Barlavento, or Windward, group of the Cape Verde islands, directly in the path of the northeast trade winds. They blow for much of the year, keeping the heat comfortable but making exposed beaches breezy and the sea choppy, especially in winter.

Year-Round Warmth. Daytime temperatures typically range from around 22°C in the coolest months to around 30°C at the end of summer, so it's never truly cold, although evenings can feel cool in the wind.

Section 2: The Seasons

Four distinct periods, each with its own character.

May to July: Calm & Warm

Conditions. Pleasant, warm weather, with the gentlest winds of the year.

Temperatures. Daytime highs of roughly 25°C–27°C.

Best For. Swimming at Laginha, boat trips, and clear days for sightseeing around the island. This is the best overall window for a beach-and-culture trip.

August to September: Hot, Humid & Occasionally Rainy

Conditions. The hottest and most humid months, when the island gets most of its limited rainfall, usually as short showers rather than long wet spells. The sea is at its warmest.

Temperatures. Daytime highs of roughly 29°C–30°C.

Things to Know. Occasional heavy showers can briefly disrupt roads and local transport. August also brings the Baía das Gatas music festival, traditionally around the August full moon, when the island is busy and accommodation fills up.

October to December: The Sweet Spot

Conditions. Warm sea, low rainfall, generally clear skies, and moderate breezes before the winter winds pick up.

Temperatures. Around 27°C on average.

Best For. Swimming, snorkelling, diving, hiking, and island excursions, including crossing to Santo Antão. Many regular visitors consider this the best time of year.

January to April: Windy & Cooler

Conditions. The strongest trade winds of the year, lower humidity, and cooler evenings. Occasionally, a dry easterly wind carries fine Saharan dust, making the sky hazy.

Temperatures. Daytime highs of roughly 22°C–24°C, with noticeably cooler nights. Bring a light jacket or sweater.

Best For. Windsurfing and kitesurfing, and Mindelo's carnival in February or March. Beaches are breezier, and the sea can be rough.

Section 3: Wind, Waves & Microclimates

The weather varies more across the island than you might expect.

Windy Spots. São Pedro, near the airport, and Salamansa, on the northeast coast, take the full force of the wind and waves. They're famous for windsurfing and kitesurfing, and less reliable for a relaxed swim.

Sheltered Spots. Laginha, Mindelo's city beach, and Baía das Gatas, a lagoon protected by a reef, are the calmest places to swim on the island.

Monte Verde. At around 750 metres, the island's highest point catches moisture from the trade winds, so it's often wrapped in cloud and mist while the coast is sunny. It's noticeably cooler and windier than Mindelo, and greener than the rest of the island. Go early for the clearest views, and bring a warm layer.

The Ferry Crossing. The channel between São Vicente and Santo Antão is often choppy, and more so in the windy winter months. If you're prone to seasickness, take tablets before boarding.

Section 4: Best Time to Visit by Activity

Match the month to what you've come for.

Beaches & Sightseeing: May to July. Calm seas, warm days, and the least wind.

Swimming, Diving & Island Trips: October to December. Warm water, clear skies, and moderate winds.

Carnival: February or March. Mindelo's carnival follows the same calendar as Brazil's, so the date changes each year.

Windsurfing & Kitesurfing: January to April. The strongest and most consistent winds, at São Pedro and Salamansa.

Music Festival: August. The Baía das Gatas festival, around the full moon.

Hiking & Santo Antão: October to December. Comfortable temperatures, clearer mountain views, and generally calmer crossings than in winter.

Sea Turtles. Turtles can be seen off São Pedro through much of the year, while the nesting season on Cape Verde's beaches runs roughly from July to October. Our guide to Swimming with Turtles at São Pedro explains how to see them responsibly.

Section 5: What to Pack

A few items make the difference in São Vicente's climate.

Wind Protection. A light windbreaker or fleece for breezy evenings, the ferry, and Monte Verde, especially from January to April.

Sun Protection. The constant breeze makes the sun feel weaker than it is. Pack high-SPF sunscreen, sunglasses, a hat, and lip balm.

Water. Carry bottled water on day trips, since the island is dry and shade can be scarce.

For Rainy Months. A light rain jacket in August and September, though you may never need it.
