Warm seas, sticky days and little cooling overnight

The heat is consistent rather than extreme: days reaching 30°C account for just 3% of the month, but humidity averages 79%, so even ordinary afternoons can feel sticky. Loose, breathable clothing makes more sense than anything heavy, and it is sensible to keep midday plans gentle. Nights average 25.9°C, so do not expect much relief after sunset; prioritise a room where you can cool down comfortably. The sea is a strong reason to choose October, averaging 28.8°C and comfortably warm for swimming. This suits travellers who dislike a chilly dip, though the water will offer less of a cooling contrast to the air.

Plan for rain, not a washout or guaranteed sunshine

October is a wet choice, so leave room to rearrange outdoor plans rather than building each day around dry weather. About 19 days have measurable rain, making waterproof protection for your belongings and a light rain layer sensible packing choices. That does not tell you how long rain will last on any particular day, so neither uninterrupted sunshine nor an all-day washout is a safe assumption. Average sunshine is about 5.2 hours within 11.6 hours of daylight: there is sunshine to enjoy, but daylight is not the same as clear skies. If weather reliability drives your decision, March, February and April are the better-rated months here.
