HotWeather in Boa Vista in November
Yes - November is a good time to visit Boa Vista if you want hot days, warm sea swimming and little rain. Daytime highs average 28°C, nights stay around 23°C and the sea is about 26°C. For a UK traveller, that means summer-weight clothing rather than autumn layers. The catch is that dry weather does not mean uninterrupted sunshine, and the humidity can make the warmth feel less comfortable if you plan to be active around midday.

Hot enough for a beach holiday, warm after dark
November suits travellers who want reliable warmth without choosing Boa Vista's hottest month. Days reach 25°C almost all the time, while 30°C is reached on 10% of days, so expect hot afternoons rather than assume intense heat throughout your stay. With humidity at 72%, loose, breathable clothing is a sensible choice, especially if you find humid heat tiring. Put more active plans earlier in the day and leave room for shade around midday. Average night-time lows of 23°C mean evenings offer only modest relief from the warmth. Pack mainly light clothes; this is not a month to choose if cool nights are important for comfortable sleep.
Good swimming weather, but not sunshine all day
The sea is a strong reason to go in November: at around 26°C, it is warm enough for swimming rather than a bracing dip. Rain is unlikely to dominate your plans, with about 1 rainy day during the month, though a dry monthly average is not a promise for every stay. Sunshine needs a more measured expectation. There are about 5.3 hours of sunshine within 11.2 hours of daylight, so allow for cloudy spells rather than expecting clear skies from morning to evening. That balance suits a relaxed holiday built around swimming and time outdoors, provided you are happy with warmth even when the sun is not out.
