Weather in Liberia in July
Costa Rica · 20-year averages, July
A hard month. July asks something of you. Go in knowing what. You should expect rain on 23 days of the month, which is more days wet than dry.
July ranks 8 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 23 of the month's 31 days, 5 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 82% nothing dries, including you.
What the averages hide
Averages flatten a month, and this one hides a few things: 16 days top 30 °C — hot spells arrive, but they break; the day barely swings — 5.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 34.7 °C and the coldest night fell to 22.4 °C, and the wettest single day dropped 56 mm — roughly 34% of the month's rain in one day.
July is moderately variable: 17 mm in the driest year against 424 mm in the wettest, around an average of 165 mm. Roughly two Julys in three land near that average, and the third does something else entirely.
Wind is light at 8.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, high enough to notice on the warm days without dominating them.
How July sits in the year
Temperatures hold steady either side: 29.8 °C in June, 30.2 here, 30.4 in August. Nothing about the timing within the month matters much.
Daylight in July
Liberia sits close enough to the equator that daylight barely moves all year — 12.7 hours in July, 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.
July 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 July — 6.3 °C cooler, 1 day more rain.
So: July is a compromise. December is 32 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.
