Guanacaste weather by month: the year at a glanceMonth by monthJanuaryFebruaryMarchAprilMayJuneJulyAugustSeptemberOctoberNovemberDecemberWildlife seasons at a glanceCosta Rican public holidays in 2027Months to be careful withFrequently asked questionsGuanacaste’s year splits cleanly. December to March is almost rainless, April and November are transition months, and May to October is the rainy season, with a dip in July and the heaviest rain in September and October. At Liberia airport, October averages 339 mm of rain over 23 days; February averages half a millimeter. Crowds follow Costa Rican holidays as much as the weather, so Christmas–New Year and Holy Week (21–28 March 2027) are the busiest weeks.
How to read this calendar
Rain and temperature figures are averages for 2005–2025 from the national weather service (IMN) station at Liberia’s Daniel Oduber airport, which sits inland; beach towns can differ, and any single year can be wetter or drier. Wildlife seasons are windows, not guarantees. Tour prices are “from” prices per person in our catalog in September 2026 and change. Still choosing between the dry and green seasons? Start with the best time to visit Guanacaste.

Month by month
January
Peak dry season: 1.1 mm of rain on about 1 day, highs of 35.2 °C (95 °F) and lows of 17.1 °C (63 °F). January to March is the windiest stretch, with afternoon winds averaging over 15 knots and gusts near 31. On windy Papagayo days the sea gets rougher, so check conditions before swimming or boating.
Crowds: the Christmas–New Year peak lasts into the first week of January, and Costa Rican schools are still on their long break.
Events: Santa Cruz’s Fiestas Típicas Nacionales, honoring the Santo Cristo de Esquipulas, ran 14–18 January in 2026, with a bull tope, montaderas and marimbas.
Wildlife: northern humpbacks (November–April) and giant mantas at the Catalina Islands (November–April).
Sunset: about 5:39pm.
Book: snorkeling at the Catalina Islands (5 hours, from $115 per person) or the family-friendly Tom Cat II catamaran (from $103).
February
The driest month on the record: 0.5 mm on about 1 day, with highs of 36.4 °C (98 °F) and lows of 17.0 °C (63 °F). Average wind speed peaks this month at about 14 knots. Stormrider’s surf guide notes that Tamarindo is at its best in the dry season, with clean, offshore conditions.
Crowds: high season. In 2026 public-school classes didn’t start until 23 February, so the school holidays cover most of the month.
Wildlife: Palo Verde’s wetlands shrink through the dry season, and from about December to March waterbirds gather in the remaining lagoons, where bare trees make them easier to see.
Sunset: about 5:51pm.
Book: surf lessons in Tamarindo (90 minutes, board and rash guard included, from $69) or a Palo Verde boat tour through the Tempisque wetlands with a family-style meal (from $90).
March
Hot and still dry: 4.9 mm on about 1 day, with highs of 37.2 °C (99 °F). Clear skies are most frequent this month, and the strong winds continue.
Crowds: Holy Week 2027 runs from 21 March (Palm Sunday) to 28 March (Easter Sunday), with public holidays on 25 and 26 March. Beach hotels fill up that week, so book early.
Events: Liberia’s Fiestas Cívicas — bull riding plus free concerts and dances in Parque Mario Cañas Ruiz — ended on 8 March in 2026. Check the 2027 program.
Wildlife: night tours from Tamarindo look for nesting olive ridley and green turtles; the operator’s season is mid-November to mid-April.
Sunset: about 5:54pm.
Book: the night turtle nesting tour from Tamarindo (4 hours, from $46). Guides use red light only, no flash, and no children under 5.
April
A transition month and, on average, the hottest: highs of 37.9 °C (100 °F). Light rain returns, with 46.5 mm on about 4 days, and winds ease to a moderate 10–12 knots.
Crowds: high season tails off after early April. Juan Santamaría Day (11 April) is a public holiday; in 2027 it falls on a Sunday.
Wildlife: the last month of the northern humpback and manta windows; the Tamarindo turtle-tour season ends in mid-April.
Parks: at Rincón de la Vieja’s Las Pailas sector, the waterfall trail admits hikers from 8am to noon in the dry season. The sector is closed on Mondays, and tickets are sold only online through SINAC’s booking system.
Sunset: about 5:54pm.
Book: the Rincón de la Vieja volcano hike, waterfall swim and hot springs combo (full day, park fees, lunch and hotel pickup included, from $125). The swim is at the Oropéndola waterfall on private land next to the park, not on the park’s own trails.
May
The rains arrive: 192.7 mm on about 15 days. Highs still average 37.0 °C (99 °F), and nights warm to 20.5 °C (69 °F). Rain falls mostly in the afternoon and evening, and from May to November average winds drop to about 7 knots. One Guanacaste catamaran operator recommends morning trips in the rainy season for calm water and better snorkeling visibility.
Crowds: school is in session, and the only public holiday is Labour Day (1 May, a Saturday in 2027).
Wildlife: Ostional’s olive ridley arribadas happen almost every month; from December to June they’re smaller, typically tens of thousands of turtles.
Sunset: about 5:58pm.
Book: the Tamarindo estuary boat safari (2 hours, from $52) through the mangroves of Las Baulas National Park, looking for monkeys, crocodiles and birds.
June
The first rainfall peak: 235.8 mm on about 19 days, with thunderstorms at their first maximum. Highs average 34.4 °C (94 °F) and lows 21.3 °C (70 °F), the warmest nights of the year. Mist and low cloud that cut visibility are most common in June and October.
Crowds: school term, with no public holidays.
Roads: from now through November, Stormrider’s guide calls a 4x4 essential, and SINAC says one is preferable on the road into Palo Verde.
Sunset: about 6:06pm.
Book: family surf lessons in Playa Sámara, where the instructors are certified lifeguards (from $80), or a morning safari float on the Nosara River (2 hours, from $70).
July
Rainfall dips to 119.6 mm on about 13 days: the “veranillo” or canícula, a mid-year lull IMN links to stronger trade winds. Visit Costa Rica places it in July and August; at the airport the dip is mainly in July. Highs average 34.8 °C (95 °F).
Crowds: mid-year school holidays (6–17 July in 2026; the 2026 calendar was published in December 2025).
Events: 25 July is the Día de la Anexión del Partido de Nicoya, often called Guanacaste Day, a public holiday marking the 1824 annexation to Costa Rica. In 2026 Nicoya led the celebrations with parades, concerts, folk dancing and montaderas. In 2027 it’s a Sunday.
Wildlife: southern humpbacks (July–November) and the start of Ostional’s bigger arribadas.
Sunset: about 6:10pm, among the latest of the year.
Book: the catamaran snorkel and sunset sail from Playa Hermosa (4.5 hours, open bar and meal, from $132); whales possible, never guaranteed.
August
The rain comes back: 198.1 mm on about 18 days, with highs of 35.3 °C (96 °F). Afternoon winds start swinging to the south and southwest, a pattern that strengthens in September and October.
Crowds: three public holidays — 2 August (Our Lady of the Angels), 15 August (Mother’s Day) and 31 August (Day of the Black Person and Afro-Costa Rican Culture). In 2027 they fall on a Monday, Sunday and Tuesday.
Wildlife: Ostional’s biggest arribadas come between July and November. During an arribada you must enter with an accredited local guide (paid separately), and SINAC asks for no flash and no reflective clothing at night.
Getting there: the road to Ostional is unpaved; use a 4x4 in the rainy season.
Sunset: about 6:02pm.
Book: base yourself in Nosara and add a guided hiking and birdwatching walk (1.5 hours, binoculars and telescope provided, from $65).
September
The wet season builds: 241.3 mm on about 22 days, with highs of 34.5 °C (94 °F). Winds are the lightest of the year, averaging under 6 knots in September and October, and showers and storms favor the afternoon.
Crowds and prices: low season, with fewer foreign visitors and hotel promotions common in September and October.
Events: Independence Day, 15 September, is a public holiday (a Wednesday in 2027).
Wildlife: Nosara’s Wildlife Conservation Association says the largest arribadas come in September and October.
Sunset: about 5:44pm.
Book: keep a rainy afternoon free for a cooking class in Nosara (2 hours, lunch included, from $65), cooking on a wood-fire stove with a local chef.
October
The wettest month: 338.7 mm on about 23 days, with highs of 33.6 °C (92 °F). Winds stay light and often blow from the southwest in the afternoon, rain is most frequent later in the day, and poor visibility peaks again.
Crowds: low season, with no public holidays.
Wildlife: peak arribada season at Ostional and Southern Hemisphere humpbacks offshore. Leatherback nesting season officially opens at Las Baulas, but read the note on leatherbacks below before you plan around it.
Parks and roads: Las Pailas may restrict access in heavy rain, and the unpaved coastal road to Nosara isn’t recommended from May to November.
Sunset: about 5:26pm.
Book: a short visit to the Diamante animal sanctuary near Playa Hermosa (3 hours, from $55), which cares for animals that can’t be released to the wild.
November
Another transition month: rain falls to 154.7 mm on about 12 days, and highs average 33.4 °C (92 °F), the lowest of the year. Winds stay light until the dry-season winds build in December.
Crowds: the high-season window, as Costa Rica’s airport operators and tourism press describe it, runs from November through early April.
Wildlife: northern humpbacks and giant mantas return (both roughly November–April), and the Tamarindo turtle-tour season starts in mid-November.
Sunset: about 5:17pm, the earliest of the year. Plan drives to finish before dark.
Book: the Playa Flamingo sunset catamaran (4 hours, snorkeling, kayaks and drinks, from $95). Boarding starts at 1:30pm, which suits November’s early sunsets.
December
The dry season returns: 12.0 mm on about 3 days, with highs of 34.5 °C (94 °F). Winds pick up in the last days of the month as the Papagayo season (roughly December–April) begins.
Crowds: the busiest time of year. Hotels fill up over Christmas and New Year, so book rooms, tours and park tickets early.
Holidays: 1 December (Abolition of the Army) and 25 December (Christmas). In 2026 the school year ends on 9 December.
Wildlife: humpbacks, mantas and the Tamarindo turtle tours are all in season.
Sunset: about 5:23pm.
Book: the full-day Río Celeste, sloth sanctuary and Llanos de Cortés tour (from $122), with national park fees, lunch and hotel pickup included.

A note on leatherback turtles
Las Baulas National Park was created to protect nesting leatherbacks, and their nesting season there runs from about October to February. Numbers have collapsed: only eight nesting leatherbacks were identified in the park in the 2021–22 season, and the park suspended guided leatherback viewing shortly before the pandemic. SINAC’s park page currently says there is no turtle observation. Treat a leatherback sighting as very unlikely, and on any turtle tour, follow your guide’s rules on lights and never use flash.

Months to be careful with
September and October: the wettest months, with rain on 22–23 days on average and more low cloud and mist. Build in buffer days and plan boat trips and hikes for the morning.
Rainy-season roads (May–November): the coastal Route 160 to Nosara is mostly unpaved, with two river crossings, and isn’t recommended in these months — rental-car insurance won’t cover water damage. Use a 4x4 for Ostional and the road into Palo Verde. Our guide to getting around Guanacaste covers the options.
Rincón de la Vieja in heavy rain: from May to November, the park can restrict access to Las Pailas when it rains hard. The crater trail is closed because of volcanic activity, the sector is closed on Mondays, and tickets are sold online only. See our Rincón de la Vieja guide.
Holiday peaks: Christmas–New Year and Holy Week fill hotels. Book rooms, cars, tours and park tickets early for late December to early January and for 21–28 March 2027.
January to March winds and April heat: gusts near 31 knots can make the sea rough, and April highs average 37.9 °C (100 °F). Start outdoor plans early.
Wet years and dry years
IMN notes that El Niño years tend to bring less rain to Guanacaste — sometimes drought — while La Niña years raise the odds of above-normal rain. Averages tell you the pattern; check IMN’s outlook in the weeks before you travel.

Frequently asked questions
What is the rainiest month in Guanacaste?
October. At Liberia airport it averages 338.7 mm of rain over about 23 days (IMN, 2005–2025), followed by September at 241.3 mm over 22 days. February is the driest, at 0.5 mm.
Is December a good time to visit Guanacaste?
For weather, yes — December averages 12 mm of rain on about 3 days, and the dry season settles in. It’s also the busiest time of year, so book rooms, tours and park tickets early, and expect windier seas late in the month.
What is Guanacaste like in July?
July brings the veranillo, a mid-year dip in rain (119.6 mm on about 13 days at Liberia airport, versus 235.8 mm in June). It’s also Costa Rica’s mid-year school holiday, Guanacaste Day falls on 25 July, and Southern Hemisphere humpbacks are in the area from July to November.
When is turtle season in Guanacaste?
It depends on the beach. Olive ridley arribadas at Ostional happen year-round, with the largest from July to November. Guided tours from Tamarindo for olive ridley and green turtles run roughly mid-November to mid-April. Leatherback nesting season at Las Baulas runs about October to February, but leatherbacks are now very rare and guided viewing there is suspended.
What is the best month to visit Guanacaste?
For the most reliable dry weather, January to March — each averages under 5 mm of rain — but avoid Holy Week and the New Year period if you want fewer people. If you prefer lower prices and don’t mind rain, September and October are low season, with fewer foreign visitors and hotel deals — but they’re also the wettest months. Our dry vs. green season guide helps you decide.
When is Semana Santa in 2027?
Holy Week 2027 runs from Palm Sunday, 21 March, to Easter Sunday, 28 March. Holy Thursday (25 March) and Good Friday (26 March) are public holidays. Beach hotels fill up that week, so book early.
