Weather in Liberia in October
Costa Rica · 20-year averages, October
Shoulder season. October sits in between. You will get good days and you will lose some. You should expect rain on 27 days of the month, which is more days wet than dry.
October ranks 5 of 12 in Liberia: past the worst of the year but short of December, which is the month to book if the dates are open.
Rain on 27 of the month's 31 days, 11 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: 4 days top 30 °C — hot spells arrive, but they break; the day barely swings — 4.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest October day reached 33.3 °C and the coldest night fell to 21.7 °C, and the wettest single day dropped 157 mm — roughly 44% of the month's rain in one day.
October is moderately variable: 106 mm in the driest year against 653 mm in the wettest, around an average of 359 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.
Wind is light at 7.3 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 28.5 °C.
How October sits in the year
Temperatures hold steady either side: 29.4 °C in September, 28.5 here, 28.8 in November. Nothing about the timing within the month matters much. Rain is the thing that moves: November brings 12 days less of it, so pushing the dates later buys drier weather.
Daylight in October
Liberia sits close enough to the equator that daylight barely moves all year — 11.9 hours in October, against a range of just 1.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
An inland climate
Despite being inland, the year stays fairly even: 12.7 °C between the year's warmest afternoons and coldest nights.
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.
October in Liberia versus nearby
If Liberia is one option among several, the nearby comparison is worth making. Puntarenas is close enough to be a coin toss — within a degree on temperature, 2 days less rain. San José is a better bet in October — 5.9 °C cooler, 1 day less rain.
So: October is a compromise. December is 29 points better and is what Liberia is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
