Weather in Pátra in December

Shoulder season. December is shoulder season in Pátra — cheaper, quieter, and a genuine gamble. Highs sit at 14.3 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

December ranks 9 of 12 in Pátra: past the worst of the year but short of May, which is the month to book if the dates are open.

Rain on 14 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 14.3 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

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 23.2 °C and the coldest night fell to -2.8 °C, and the wettest single day dropped 42 mm — roughly 36% of the month's rain in one day.

December is moderately variable: 9 mm in the driest year against 197 mm in the wettest, around an average of 117 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.

Wind is light at 9.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 87%, which at 14.3 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How December sits in the year

Temperatures hold steady either side: 19.3 °C in November, 14.3 here, 12.8 in January. Nothing about the timing within the month matters much.

Daylight in December

December sits at the dark end of Pátra's year — 9.5 hours of daylight against 14.8 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 18.3 °C in December — swimmable, but it takes a moment to commit. The sea peaks at 26.6 °C in August and bottoms out at 15.5 °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

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

December in Pátra versus nearby

If Pátra is one option among several, the nearby comparison is worth making. Kalamata is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Volos is close enough to be a coin toss — within a degree on temperature, 4 days less rain.

So: December is a compromise. May is 35 points better and is what Pátra is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
