Boa Vista or Sal: choose your level of heat
Choose Boa Vista if hotter afternoons are a priority: its average daytime temperature is 29°C, compared with 27°C on Sal. That makes Sal the better fit if you want warmth with a little less daytime heat, rather than genuinely cool conditions. The distinction largely disappears after sunset, as both destinations average 25°C at night. Both also have sea temperatures of 27°C and average 2 rainy days, so neither has an advantage on those measures. For a swimming-focused holiday, either fits the brief. Let your tolerance for daytime heat guide the choice rather than expecting a different kind of October weather on each island.
What the weather means for your day
Pack light, breathable clothes and plan for evenings that remain warm rather than providing much relief from the daytime heat. With a country daytime average of 28°C, it makes sense to leave more energetic plans for the cooler parts of the day and take shade breaks around midday. Sun protection belongs in your daily routine, even when the sky is not clear throughout. Average sunshine is 6.3 hours a day, so do not read the warmth as a promise of uninterrupted blue skies. If warm bedrooms make sleep difficult for you, checking the cooling arrangements before booking matters more than packing extra evening layers.
