מזג האוויר בBoa Vista באוקטובר

Boa Vista's forum describes January as reliably warm and sunny for sunbathing, typically around 25C with the odd cloudy day, though multiple posters flagged the wind as genuinely chilly at times even under clear skies - it's the kind of place where a cardigan for the evening is worth packing despite the warm days. The pool and sea were described as too cold for comfortable swimming by some visitors, matching the island's relatively cool January water. An occasional Saharan dust event can roll through for a few days and, in rare cases, disrupt flights.

Forum posters call July technically the start of the rainy season but say you'd be unlucky to see more than a quick, short shower - high-20sC temperatures with plenty of sun are the norm. One repeat visitor who's been to Boa Vista in July and August many times reports never experiencing bad weather, describing it as very hot by day with a lovely, welcoming breeze that keeps things comfortable despite the heat - though that same breeze can mask sun exposure, so posters stress applying sunscreen generously regardless of how pleasant it feels. Wind itself is actually strongest in winter, not July, making midsummer comparatively calmer on that front.
