Warm rather than reliably hot
Mellieha in June suits travellers who want warmth without making very hot weather the point of the trip. Days reach 25°C around 31% of the time, while 30°C is reached on just 1% of days. That makes daytime exploring and eating outdoors a reasonable plan, though shade is still sensible around midday. Humidity averages 77%, so the air can feel muggy rather than crisply dry. Pack mainly light, breathable clothing, with a light layer for evenings: the coldest 10% of nights fall to 17.5°C or below. If your priority is consistent high heat, June may feel milder than you expect.
Dry days with plenty of time outside
Rain is unlikely to dominate a June holiday: there is about 1 rainy day during the month, so wet-weather plans can stay in reserve rather than shape the trip. Around 12.2 hours of sunshine within 14.4 hours of daylight give you room to move longer walks away from midday and leave swimming for whichever part of the day feels comfortable. Sun protection matters even when the temperature feels moderate. The sea averages 22.2°C, which puts it in the swimming range, although it may feel cool when you first get in. This combination suits a holiday split between time in the water and time outdoors, rather than a trip built around very hot afternoons.
