Santo Antão in July

Santo Antão's hiking season runs from November through May, when temperatures stay comfortable and rain transforms the landscape into something magical. But timing your visit right can make the difference between good hiking and absolutely epic hiking. December through February offers perfect conditions. Daytime temperatures hover around 24°C, nights cool down to 18°C, and the harmattan winds from the Sahara stay away. This is peak season, so book accommodation early and expect higher prices. The Christmas period gets especially busy with Cape Verdean diaspora returning home. March and April might be the sweet spot. Weather remains ideal, crowds thin out, and the landscape reaches peak greenness from winter rains. Wildflowers bloom in the valleys, and waterfalls that were dry in November start flowing again. Hotel rates drop slightly, and you'll have trails mostly to yourself. May brings warmer temperatures but still excellent hiking conditions. The trade winds pick up, providing natural air conditioning during climbs. This is when local farmers harvest sugarcane, so you'll see traditional processing methods in action throughout the valleys. June through October is hot and humid, with temperatures reaching 30°C and occasional tropical storms. Serious hikers can still manage early morning and late afternoon adventures, but midday becomes unbearable. Accommodation prices drop significantly, and you'll experience the island with almost no other tourists. The harmattan winds blow from December through March, bringing dust from the Sahara that can limit visibility and irritate sensitive throats. But they also create some of the most dramatic sunsets you'll ever see. Rain patterns are unpredictable. Some years bring abundant rainfall that turns the island emerald green. Others stay dry, leaving the landscape brown and stark. Check recent weather reports before booking, especially if green valleys are important to your experience.
