- Envision Festival (Feb-Mar)
- Tope Nacional (Dec 26)

When to Visit by Travel Goal
- Best weather: Visit during December-April (dry season). Comfortable temperatures, low rainfall, manageable crowds.
- Lowest prices: May-November (green season). Hotels and flights cut 30-50%. Trade weather for savings.
- Fewest crowds: Just outside peak season — first 2 weeks before peak begins or last 2 weeks after peak ends.
- Festivals & culture: See the events list above. Book 3-6 months ahead for major dates.
- Outdoor activities: Avoid peak rain/hurricane months. December-April (dry season) is generally optimal.
- Budget travelers: Mid-week flights in off-season offer the best deals. Set Google Flights alerts 6-8 weeks ahead.
What to Avoid
- Peak crowds: December-February brings 2-3x the visitors. Major sites require ticket reservations weeks ahead.
- Major holidays: Local school holidays and religious festivals drive domestic travel surges — popular spots fill up.
- Closures: Some sights and restaurants close during deep off-season. Verify business hours before booking.
Booking Tips
- Book flights 8-12 weeks ahead for peak season; 4-6 weeks for off-season usually works.
- Set Google Flights price alerts for your target dates.
- Watch shoulder weeks: the week just before/after peak season often has near-peak weather at 30% lower prices.
- Check local school holidays — these spike domestic travel and crowd major sites.
- Travel insurance is wise for any peak-season trip given high prices and harder-to-rebook flights.
The Catch the Calendar Hides: Why September and October Split Costa Rica in Two
The dry-season-versus-green-season split is real, but it quietly assumes you are heading to the Pacific. Costa Rica has two opposing weather clocks, and reading the wrong one is how people book the rainiest fortnight of the year by accident. September and October are the soggiest stretch on the Pacific side, when westerly storms known as the temporales del Pacifico can park over the southern coast and the Osa Peninsula for days, and some remote lodges and tour operators simply close until November.
Cross to the Caribbean in those same weeks and the pattern flips. The Talamanca mountains wring the moisture out before it reaches Puerto Viejo, Cahuita and Manzanillo, so late September into October is the sunniest, calmest window of their year, with coastal highs around 80 to 88 degrees Fahrenheit and stretches of rain-free days. It is the closest thing to a secret high season the country has.
Two more timing notes worth banking:
- A short dry break called the veranillo, or little summer, often interrupts the rains across the Pacific in July and into August, giving green-season prices with drier afternoons.
- For the classic Pacific itinerary, May and November remain the shoulder sweet spot; if your heart is set on the Caribbean, invert that and aim for September and October instead.
