Weather in Liberia in January
Costa Rica · 20-year averages, January
A good month. January works. It is not the peak, but nothing about it fights you. Highs average 32.1 °C, lows 22.8 °C, and rain falls on 1 days — nothing in the month is working against you.
January ranks 2 of 12 in Liberia. Only December scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain falls on only 1 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 32.1 °C days and 22.8 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: 27 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest January day reached 35.6 °C and the coldest night fell to 19.7 °C.
January is dependably dry, and that reliability is the point: across the twenty years measured, the wettest January on record still only managed 21 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Januarys brought 4 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.
Wind is light at 15.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 69%.
How January sits in the year
The month is on the way up: 2 °C warmer than December, and February adds another 1.7 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in January
Liberia sits close enough to the equator that daylight barely moves all year — 11.6 hours in January, 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
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.
January 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, 3 days more rain. San José is a better bet in January — 7.7 °C cooler, 8 days more rain.
So: January is effectively as good as it gets here — 6 points behind December, which is inside the margin where the weather stops being the deciding factor and price starts being it.
