The Barlavento Islands are the northern arc of the Cape Verde archipelago, a volcanic chain rising from the Atlantic roughly 350 miles off the West African coast. Six inhabited islands make up the group, and the contrasts between them are striking: Sal and Boa Vista are flat and sun-scorched, fringed by white-sand beaches and turquoise shallows, while Santo Antão and São Nicolau are mountainous and dramatically green, laced with terraced valleys and cobblestone hiking trails that drop thousands of feet to the sea. Mindelo, the cultural capital on São Vicente, pulses with live morna and funaná music spilling from harbor-front bars most evenings, and the Creole food scene here revolves around cachupa, a slow-cooked stew of corn, beans, and fish that changes from kitchen to kitchen.
Your best window runs from early December through early June, when dry trade winds keep skies clear, temperatures stay comfortable, and the islands are at their most versatile. Winter months from December through February deliver prime kitesurfing conditions on Sal and Boa Vista, and the Mindelo Carnival, typically falling in February or early March, fills the streets with Brazilian-influenced parades and live music. Spring extends the sweet spot with humpback whale watching off Boa Vista from March through May and ideal conditions for hiking the green valleys of Santo Antão. If you prefer fewer crowds and lower accommodation costs, the shoulder months of March and April offer the best balance of good weather and thinner tourist numbers.
Spring in Barlavento Islands, Cape Verde
Spring is when the Barlavento Islands shift from wind-sport playground to wildlife stage. Humpback whales migrate through Cape Verdean waters from March to May, and Boa Vista is one of only two breeding sites for these animals in the entire North Atlantic. Boat tours depart from the island's western coast, and sightings are most reliable in March and April. On land, the trade winds begin to ease, and Santo Antão's mountain trails become more pleasant for long hikes; the coastal path from Ponta do Sol to Cruzinha, with its views of the cliffside village of Fontainhas perched among terraced fields, is one of the most photographed routes in all of Cape Verde. Afternoon highs average 78.6°F (25.9°C), warm enough for a full day outdoors without the intensity that summer brings.
Morning lows of 67.7°F (19.8°C) keep early starts comfortable, so you can hit the trails at dawn without layering up heavily. Rain is essentially nonexistent across these three months, with showers appearing on just one to three days total during the entire season. The persistent breeze does pick up through May, when gusts can reach fresh-breeze levels, so pack a light windbreaker if you plan to be on exposed ridgelines or open boats. This is also when Boa Vista hosts the Pidróna Festival in early May, a community street celebration in Rabil featuring traditional games and drumming.
Tourism picks up in May but remains fairly moderate compared to the winter peak. Accommodation prices stay reasonable, making spring one of the better value windows for island-hopping. If you want to pair whale-watching excursions with unhurried beach days on Sal's Santa Maria beach, this is the season to do it.
Summer in Barlavento Islands, Cape Verde
Summer transforms the Barlavento Islands into their liveliest season. This is the busiest period for tourism, driven partly by European school holidays and partly by two major draws: loggerhead turtle nesting and the archipelago's biggest music festivals. On Sal and Boa Vista, thousands of loggerhead turtles come ashore to nest from July through the end of the season, and guided nighttime excursions let you watch these ancient animals dig nests and lay eggs on moonlit beaches. On São Vicente, the Baía das Gatas Music Festival takes over a beach lagoon during the August full moon weekend, drawing tens of thousands of people for one of West Africa's largest outdoor music events.
The weather shifts noticeably warmer, with seasonal highs averaging 83.5°F (28.6°C) and lows settling around 73.4°F (23°C). Humidity climbs into the low 70s, and the trade winds that define winter and spring drop off considerably, making the sea calmer for swimming but the air thicker on shore. Rain remains rare in June and July, though August sees a slight uptick to about two days of precipitation. The Kavala Fresk Festival, a food-focused celebration in Mindelo, typically falls in mid-July and gives you a chance to taste Cape Verdean dishes from grilled fish to cachupa alongside local grogue, the islands' sugarcane spirit.
Expect accommodation prices to climb, especially on Sal and around festival dates on São Vicente. Book well ahead if your trip overlaps with the Baía das Gatas weekend. A wide-brimmed hat, reef-safe sunscreen, and water shoes for rocky beach entries are essentials for this stretch of the year.
Fall in Barlavento Islands, Cape Verde
Fall is the quietest and cheapest time to visit the Barlavento Islands. Tourist volumes drop sharply, with October being the least-visited month across the archipelago. If you are after solitude on Boa Vista's wide beaches or want Santo Antão's trails largely to yourself, this is the window. The Santa Maria Music Festival on Sal, typically held in mid-September, brings international artists to the beach town for a lively weekend of live music, and the MindelAct international theatre festival fills Mindelo's stages around the same time.
Temperatures reach their annual peak during this season, with highs averaging 85.5°F (29.7°C) and lows of 75.1°F (23.9°C). Late September pushes to the hottest stretch of the year, when highs hit 87.9°F (31.1°C) and overnight temperatures stay around 77.2°F (25.1°C). September is also the one month with meaningful rain, seeing wet days roughly 12% of the time, though showers tend to be short bursts rather than all-day downpours. On the mountainous islands, those rains turn valleys green and occasionally swell the ribeiras, the seasonal riverbeds that thread through Santo Antão's gorges.
Accommodation is priced at its most affordable, and you will have little trouble finding availability without advance booking. Turtle nesting continues into early October on Sal and Boa Vista, so late-season wildlife viewing is still possible. Bring lightweight, breathable clothing and stay hydrated; the combination of heat and humidity is at its most intense during September.
Winter in Barlavento Islands, Cape Verde
Winter is when the Barlavento Islands are at their most magnetic. The Mindelo Carnival, typically held on Shrove Tuesday in February, is the cultural highlight of the year on São Vicente. Colorful parades wind through Mindelo's streets, samba-influenced floats compete for attention, and the energy carries through a full week of pre-Carnival parties and music. This is also prime season for kitesurfing and windsurfing on Sal and Boa Vista, where steady trade winds create world-class conditions from December through February. Winds regularly reach 17 to 18 knots, and surf schools along Santa Maria and Kite Beach cater to all skill levels.
The weather is as close to perfect as the tropics get. Highs average 77.8°F (25.4°C) with lows dipping to a pleasant 67.2°F (19.6°C), and humidity sits in the low 60s. Rain is virtually absent; you can count on clear skies for your entire trip. December draws a surge of visitors escaping northern European winters, and the New Year's Eve celebrations across the islands are festive and oceanside. January sees the crowd thin slightly, making it a smart pick if you want winter weather without December's price premium.
This is the second-busiest tourism season, so booking accommodation early is wise, especially on Sal and around Carnival on São Vicente. A light hoodie or windbreaker earns its place in your bag for breezy evenings and open-water boat crossings. The sun sits lower in the sky, but it is still strong at this latitude; SPF protection remains non-negotiable even on overcast days.

Travel Tips & Safety for Barlavento Islands, Cape Verde
Getting between islands requires either short inter-island flights or ferry crossings. The ferry from Mindelo (São Vicente) to Porto Novo (Santo Antão) runs multiple times daily and takes about an hour. For Sal and Boa Vista, internal flights are the fastest option, and booking ahead through local carriers secures better availability. The official language is Portuguese, but Cape Verdean Creole is what you will hear most often in daily life; English is spoken at hotels and tour operators on the more touristic islands. Tap water is not recommended for drinking, so stick to bottled or filtered water throughout your stay.
Cape Verde is generally considered safe for visitors. Keep standard precautions with valuables on busy beaches and in town centers, particularly in Santa Maria on Sal and in Mindelo. Ocean currents can be strong on exposed Atlantic-facing beaches, so swim at sheltered bays or spots where locals swim. The equatorial sun is intense year-round; a high-SPF sunscreen, hat, and plenty of water should travel with you daily.
