Weather in Antalya in December

A good month. December works. It is not the peak, but nothing about it fights you. Highs average 16.3 °C, lows 7.9 °C, and rain falls on 11 days — nothing in the month is working against you.

December ranks 8 of 12 in Antalya: past the worst of the year but short of April, which is the month to book if the dates are open.

The rain arrives in bursts — 5 of the 11 wet days are heavy ones. Mornings tend to hold; build the outdoor half of each day before lunch and keep the afternoon flexible. Pack for 16.3 °C days and 7.9 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest December day reached 24.6 °C and the coldest night fell to -1.7 °C, and the wettest single day dropped 87 mm — roughly 50% of the month's rain in one day.

December is moderately variable: 14 mm in the driest year against 442 mm in the wettest, around an average of 174 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.

Wind is light at 8.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.

How December sits in the year

The month is on the way down: 5.5 °C cooler than November, with January dropping another 2 °C. The first week and the last are not the same trip.

Daylight in December

December sits at the dark end of Antalya's year — 9.7 hours of daylight against 14.7 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 19.2 °C in December — swimmable, but it takes a moment to commit. The sea peaks at 28.9 °C in August and bottoms out at 16.9 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

December in Antalya versus nearby

If Antalya is one option among several, the nearby comparison is worth making. Konya is the weaker option in December — 8.4 °C cooler, 1 day less rain. Ródos is close enough to be a coin toss — within a degree on temperature, 2 days more rain.

So: December is a compromise. April is 22 points better and is what Antalya is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
