Your January weather guide
CoolWeather in Dalaman in January
Dalaman in January suits a trip for mild daytime weather, not a beach holiday. Average highs are around 14°C, nights fall to around 7°C, and about 11 days have rain.

Daytime and night-time in January

Nights average 6.8°C; one night in ten drops to 3.4°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 19.3°C (1998-01-13) and the coldest night -3.2°C (2015-01-08).

Wet (more than 8 rainy days): about 11 days with 1 mm or more, 168 mm in total. Year to year it varies a lot - the wettest January was 2019 with 379 mm, the driest 1992 with 2 mm. Humidity averages 73%.

Is January a good time to visit Dalaman?
January is not the strongest month here: cool days and frequent rain. The best months for Dalaman on our scoring are September, June, October; months averaging 25°C or more: Jun, Jul, Aug, Sep, Oct.
Comfortable for walking, too cool for beach days
January is Dalaman's coolest month, so think light jumper and jacket rather than summer clothes. The warmer days reach 16.4°C or more, which can make walking pleasant, but that is not dependable sunbathing weather. Evenings need warmer layers: the average night is cool, and the coldest nights fall to 3.4°C or below. The sea averages 17.9°C, putting it in the cold category rather than comfortable holiday-swimming territory. If you enjoy a brief cold dip, that may be acceptable, but do not build the trip around relaxed swims. This month is a better fit for travellers who prefer being active outdoors to lying on the beach.
Leave room for rain in your plans
Rain is the main catch. With about 11 rainy days and 168.0 mm across the month, a waterproof jacket and shoes that cope with wet ground are sensible packing choices. Keep outdoor plans flexible rather than relying on a dry run of days. There is still useful daylight: January averages about 5.0 hours of sunshine within 9.7 hours of daylight, so wet weather does not mean constant gloom. Make use of dry spells for longer walks, and keep something indoors in reserve. The shorter daylight window also favours getting out earlier rather than leaving your main outdoor plans until late afternoon.
