Warm rather than hot

Mellieha's average daytime high is 8.2°C warmer than London's in October, so the change should feel noticeable without bringing the usual demands of very hot weather. Light clothes are a sensible starting point for daytime, with a layer to add when you feel cooler. Days reaching 25°C account for just 10%, so this is not the month to choose if that level of warmth is essential. Midday is a sensible time to aim for the warmer part of your day outdoors. October suits travellers who prefer comfortable warmth for getting about over heat that dictates their plans.

The sea is a strong reason to go

At an average 23.8°C, the sea is warm enough for swimming and is a stronger reason to choose October than the prospect of hot afternoons. The year-to-year range of 23°C to 25°C also supports that judgement, though personal tolerance still matters. Pack swimwear, but do not make every day's plans depend on sitting beside the water in sunshine. There are about 6.5 hours of sunshine within 11.1 hours of daylight, leaving useful time outdoors without promising clear skies throughout. This is a good fit if swimming matters to you more than reliably hot weather on land.

Allow for rain rather than ruling October out

About 7 days receive measurable rain, so October needs a more flexible approach than a trip built entirely around dry weather. That does not tell you how long any shower will last, and it is not a reason to assume those days are lost. A light waterproof is a practical addition to your packing, and it helps to keep your outdoor plans movable. Choose Mellieha then if you can accept some weather interruptions in return for warmth and a swimmable sea. If guaranteed dry days are your deciding factor, the October averages do not offer that reassurance.
