Hot days, warm seas and little evening cooling

The heat is dependable: days reach 25°C throughout October, although 30°C is less routine. Humidity averages 84%, so loose, breathable clothing is a better choice than anything heavy or close-fitting. Keep more active plans flexible and leave room for a rest around midday, particularly if muggy weather tires you out. Nights average 24.6°C, so evenings offer limited cooling rather than a crisp break from the day. The sea is a strong reason to come, averaging 28.8°C: comfortably warm for swimming on temperature alone. Pack light clothes for evenings as well as daytime, and choose accommodation where you can cool down comfortably.

Rain is the main compromise

With about 20 rainy days, October is a poor match for anyone whose holiday depends on consistently dry outdoor time. That figure does not mean every wet day is a washout, but it does make a flexible itinerary more sensible than a tightly packed schedule. Sunshine averages about 4.6 hours within 11.5 hours of daylight, so do not picture uninterrupted blue skies. Bring a light waterproof and keep an indoor alternative in mind for plans that depend on dry weather. October works best if you value warmth more than sunshine reliability and can accept changing plans. If rain would spoil the trip for you, choose another month rather than relying on a dry spell.
