Weather in Limón in December

Shoulder season. December sits in between. You will get good days and you will lose some. You should expect rain on 23 days of the month, which is more days wet than dry.

Limón barely has seasons. December scores 54 out of 100 against a best of 64 in February — a gap small enough that the month you choose matters far less here than the week you choose.

Rain on 23 of the month's 31 days, 6 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 87% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average December reaches 30 °C; the day barely swings — 3.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest December day reached 29.8 °C and the coldest night fell to 22.5 °C, and the wettest single day dropped 153 mm — roughly 69% of the month's rain in one day.

December is moderately variable: 49 mm in the driest year against 633 mm in the wettest, around an average of 222 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.

Wind is light at 5.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 87% is the real story though — it is the number that decides how the day feels, not the 28.1 °C.

How December sits in the year

Temperatures hold steady either side: 28.2 °C in November, 28.1 here, 27.7 in January. Nothing about the timing within the month matters much. Rain is the thing that moves: January brings 6 days less of it, so pushing the dates later buys drier weather.

Daylight in December

Limón sits close enough to the equator that daylight barely moves all year — 11.5 hours in December, against a range of just 1.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 27.9 °C in December — warm enough that the water offers no relief from the heat. The sea peaks at 29.1 °C in September and bottoms out at 27.3 °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

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

December in Limón versus nearby

If Limón is one option among several, the nearby comparison is worth making. San Isidro is close enough to be a coin toss — 2 °C cooler, 4 days less rain. San José is a better bet in December — 4.4 °C cooler, 9 days less rain.

So: December works, with February the better month by 10 points if the dates can move. If they cannot, nothing here should stop you booking.
