Daytime and night-time in January
The typical January day in Mellieha peaks at 14.2°C, but that is an average: the warmest 10% of days reach 16.3°C or more. Days over 25°C are rare. Nights average 11.6°C; one night in ten drops to 8.9°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest January day here reached 18.7°C (2010-01-01) and the coldest night 5.9°C (2002-01-02).

Wet (more than 8 rainy days): about 9 days with 1 mm or more, 56 mm in total. Year to year it varies a lot - the wettest January was 2006 with 189 mm, the driest 2007 with 5 mm. Humidity averages 70%.

Milder than London, but still cool
The daytime high is 6.8°C above London's January average, so Mellieha offers a meaningful change without delivering summer warmth. Walking and spending time outdoors are more realistic priorities than lying in the sun. Pack trousers, tops you can layer and a jacket that can stay with you into the evening. Average night temperatures of 11.6°C sound fairly mild, but the coldest nights can drop to 8.9°C or below, so do not pack only for the average. Warmer days reach 16.3°C or more, which may feel pleasant in sunshine, but midday heat is not the concern here. This suits travellers who prefer cool conditions and do not need beach weather to enjoy a holiday.
Make the most of daylight and keep plans flexible
Expect about 9 rainy days, making a waterproof outer layer a more useful packing choice than relying on an umbrella alone. Keep outdoor plans flexible rather than committing every day to being outside. There are about 5.2 hours of sunshine within 9.8 hours of daylight, so January is not without bright spells, but sunshine should be treated as a welcome part of the trip rather than a promise. Put outdoor time into the brighter parts of the forecast and have an indoor alternative ready for wetter weather. With limited daylight and cooler evenings, it makes sense to start daytime plans promptly rather than leaving most of your time outside until late afternoon.
