Warm days without dependable heat
Valletta in October suits travellers who prefer being outdoors in warmth without making strong heat the point of the holiday. Daytime highs average 23.1°C, while only 15% of days reach 25°C, so this is not the month to choose for reliably hot afternoons. Humidity averages 74%, which can make the warmth feel more noticeable, particularly when walking around at midday. Light clothing is a sensible starting point, with a light layer for later. Nights average 20.2°C, although the colder nights can fall to 17.8°C or below. Plan for mild evenings, but do not pack as though every evening will feel summery.
A warm sea, but leave room for rain
The sea is a strong reason to consider October: at 23.8°C on average, it remains warm enough for swimming rather than just a quick, bracing dip. That makes a trip combining time outdoors with swims a reasonable choice, provided you can adjust your plans to the weather. There are about 6 rainy days during the month, so a light waterproof deserves space in your bag. Sunshine averages about 6.5 hours within 11.1 hours of daylight, leaving scope for time outside without promising clear skies throughout the day. Keep swimming plans flexible and use the brighter spells when they arrive, rather than relying on every afternoon being suitable.
