Weather in Liberia in June
Costa Rica · 20-year averages, June
Shoulder season. June sits in between. You will get good days and you will lose some. You should expect rain on 25 days of the month, which is more days wet than dry.
June ranks 7 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 25 of the month's 30 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 83% nothing dries, including you.
What the averages hide
Averages flatten a month, and this one hides a few things: 12 days top 30 °C — hot spells arrive, but they break; the day barely swings — 5.2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 35.1 °C and the coldest night fell to 22.3 °C, and the wettest single day dropped 74 mm — roughly 33% of the month's rain in one day.
June is moderately variable: 76 mm in the driest year against 393 mm in the wettest, around an average of 226 mm. Roughly two Junes in three land near that average, and the third does something else entirely.
Wind is light at 7.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.
How June sits in the year
Temperatures hold steady either side: 32.6 °C in May, 29.8 here, 30.2 in July. Nothing about the timing within the month matters much.
Daylight in June
Liberia sits close enough to the equator that daylight barely moves all year — 12.7 hours in June, 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
Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
June 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 June — 5.9 °C cooler, the same number of rain days.
So: June is a compromise. December is 31 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.
