Weather in Limón in August

Shoulder season. August sits in between. You will get good days and you will lose some. You should expect rain on 29 days of the month, which is more days wet than dry.

Limón barely has seasons. August scores 50 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 29 of the month's 31 days, 8 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 88% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 3.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest August day reached 31 °C and the coldest night fell to 23.3 °C, and the wettest single day dropped 101 mm — roughly 40% of the month's rain in one day.

August is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest August on record still delivered 432 mm against 122 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 254 mm average is a reasonable planning figure, not a promise.

Wind is light at 3.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 88% is the real story though — it is the number that decides how the day feels, not the 28.7 °C.

How August sits in the year

Temperatures hold steady either side: 28.5 °C in July, 28.7 here, 28.9 in September. Nothing about the timing within the month matters much.

Daylight in August

Limón sits close enough to the equator that daylight barely moves all year — 12.5 hours in August, 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 28.6 °C in August — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

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.

August 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 — 2.2 °C cooler, 3 days less rain. San José is a better bet in August — 4.8 °C cooler, 5 days less rain.

So: August works, with February the better month by 14 points if the dates can move. If they cannot, nothing here should stop you booking.
