Your January weather guide
CoolWeather in Valletta in January
January suits a Valletta city break if you want milder days rather than winter heat. Average daytime highs are 14.6°C, nights average 11.9°C, and the sea is cold at 16°C. For a UK traveller, that means time outdoors can be comfortable with layers, but this is not a reliable beach holiday. Go if you are happy to work around showers and spend evenings in a jacket; choose another month if warmth is the main reason for travelling.

Daytime and night-time in January

Nights average 11.9°C; one night in ten drops to 9.5°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 18.8°C (2010-01-01) and the coldest night 6.2°C (2015-01-01).

Milder than London, but pack for cool weather
Valletta's average January daytime high is 7.2°C above London's 7.4°C, so the difference should be useful for a break spent walking around. Still, mild is the right expectation, not hot: even the warmest 10% of days reach only 16.7°C or more. Plan on trousers, comfortable closed shoes and layers you can adjust during the day. A jacket remains useful after dark, and the coldest 10% of nights fall to 9.5°C or below. January sits near the cool end of Valletta's year, so it suits travellers who prefer being active without summer heat more than those hoping to sit outside in light clothing all evening.
Leave room for rain in your plans
Rain is the main catch: January has about 9 rainy days, so a rigid outdoor itinerary is less sensible than plans you can rearrange. Pack a waterproof outer layer and shoes you would be happy wearing on wet streets. There is still useful daylight, with about 5.2 hours of sunshine out of 9.8 hours of daylight, but that does not promise clear skies throughout your stay. Put weather-dependent plans into the brighter spells and keep indoor time flexible. With daylight limited, it makes sense to start outdoor days promptly rather than leave most of your walking until late afternoon.
