Expect heat that lasts into the evening

This is Mellieha's warmest month, and the warmth is dependable: 98% of days reach 25°C. That makes light, breathable clothing more useful than layers, but it also means there is little prospect of a cool day for more energetic plans. Humidity averages 75%, so conditions can feel muggy, particularly when you are moving around. Keep longer walks for the morning or later in the day, and leave room for shade and a slower pace around midday. Nights remain warm rather than offering a sharp cooldown, so air conditioning is worth prioritising when choosing accommodation. For travellers who struggle to sleep in heat, that is a more important consideration than packing a jacket.

Warm swimming water, with little need for a rain plan

The sea is firmly in comfortable swimming territory, making August a good fit if time in the water is central to your holiday. Its year-to-year range of 26°C to 28°C suggests you should not expect a chilly dip, though it may offer less of a cooling contrast than you would like on a hot afternoon. Sunshine averages about 12.4 hours a day, leaving plenty of scope to swim outside the strongest midday heat. Pack sun protection and something to cover your skin between swims. With about 1 rainy day during the month, a flexible outdoor plan makes more sense than organising the trip around wet-weather alternatives.
