Best Time to Visit Costa Rica: Month by Month

Costa Rica is one of those places where the month you pick matters more than the destination itself. Go in February and you get wall-to-wall sunshine on the Pacific coast. Go in October and half the country is getting drenched while the other half is having its best weather of the year. The country runs on two seasons, not four, and once you understand how they work the whole calendar makes sense. Here is what every month actually looks like for weather, crowds, prices, and wildlife, so you can match the timing to the trip you want.

The short answer: when is the best time to visit Costa Rica?

The best time to visit Costa Rica is the dry season, which runs from mid-December through April. This is when you get reliable sunshine, the easiest road conditions, and the best beach weather on the popular Pacific coast. It is also the busiest and most expensive stretch of the year.

If you want the sweet spot between good weather and good value, aim for the shoulder months: late November to mid-December, and May to early June. You trade a few afternoon showers for lower prices and far thinner crowds.

Costa Rica's two seasons, explained

Costa Rica has a dry season and a green season, not the four seasons you are used to.

• Dry season (December to April): Locals call it verano, or summer. Sunny days, low rainfall on the Pacific side, dusty roads, and peak tourism. This is high season.
• Green season (May to November): Locals call it invierno, or winter. Mornings are often clear and sunny, then rain rolls in during the afternoon or evening. The landscape turns brilliant green, waterfalls run full, and prices drop. This is also called the rainy or low season.

One important wrinkle: the Caribbean coast (Puerto Viejo, Cahuita, Tortuguero) runs on a different rhythm. It sees more rain during the Pacific dry season and often enjoys a drier, sunnier spell in September and October, exactly when the Pacific side is at its wettest. If you are set on visiting during September or October, the Caribbean coast is frequently the smarter call.

Month-by-month breakdown

January

Peak dry season. Bright, sunny days on the Pacific coast and comfortable temperatures. Crowds and prices stay high after the holiday rush, but the weather is about as reliable as it gets. Great for first-timers who want guaranteed sunshine.

February

Statistically one of the driest, sunniest months of the year. This is prime beach and adventure weather across the Pacific coast and Central Valley. Book early, because it is one of the most popular months for international visitors.

March

Still solidly dry and sunny, with rising temperatures and very green-free, golden landscapes in Guanacaste. Spring break traffic picks up, so beaches and top lodges fill fast. Excellent conditions, high demand.

April

The tail end of the dry season and often the hottest, driest month. Prices spike around Easter week (Semana Santa), when Costa Ricans travel domestically and beaches get crowded. Book well ahead if your dates land near the holiday. Late April can be a quiet, warm value window as the first green-season showers begin.

May

The green season begins. Expect sunny mornings and short afternoon showers rather than all-day rain. The countryside turns lush, waterfalls swell, and prices fall noticeably from the peak. May is one of the best value months of the year.

June

Green season in full swing, with reliable morning sun and afternoon rain. Landscapes are gorgeous and crowds are light. A strong pick for budget-minded travelers who do not mind planning activities for the first half of the day.

July

Many years bring a brief drier spell mid-season, sometimes called the veranillo, or little summer. Rain eases up for a couple of weeks, making July a surprisingly good month. It is also a popular time for North American families, so expect a modest uptick in visitors.

August

Green season continues with afternoon downpours. This is when humpback whales arrive along the southern Pacific coast near Marino Ballena National Park, and whale watching gets excellent. Mornings are often clear, and prices stay friendly.

September

The wettest month on the Pacific coast, and the quietest and cheapest for tourism. If you want the Pacific side, this is a gamble. But the Caribbean coast is often at its sunniest and driest right now, so shift east and you can have a beautiful, uncrowded, low-cost trip.

October

Along with September, the wettest stretch on the Pacific side. Some remote lodges and roads can be affected by heavy rain. The upside is rock-bottom prices and lush scenery, plus green sea turtle nesting season winding down at Tortuguero on the Caribbean coast, which stays comparatively dry and pleasant.

November

The rains taper off, especially in the second half of the month. Prices are still low, crowds are thin, and the country is at its greenest. Late November is one of the best value windows on the whole calendar: near-dry-season weather at green-season prices.

December

The dry season returns, usually by mid-month. Early December is a fantastic mix of good weather and lower prices before the holidays. From about December 20 onward, prices and crowds surge for Christmas and New Year, so book that stretch far in advance.

Best time to visit for what you care about

Front-loading the answer by trip type:

• Cheapest trip: September and October, when Pacific-side rain drives prices to their annual low. Consider the Caribbean coast for better weather at the same price.
• Best weather, any price: January through March, the heart of the dry season.
• Best value (weather plus price): late November to mid-December, and the month of May.
• Whale watching: the southern Pacific coast sees humpbacks roughly August to October, with another window December to March.
• Sea turtle nesting: Tortuguero on the Caribbean coast is a major green turtle nesting site, broadly July to October.
• Surfing: the Pacific coast has consistent swell year-round, with the biggest, most reliable waves during the green season (May to November).

How Costa Rica timing compares to a Caribbean beach trip

Costa Rica's green season overlaps almost exactly with Caribbean hurricane season, roughly June through November. The difference is that Costa Rica's rain is usually predictable afternoon showers rather than storm systems, and the country sits outside the main hurricane belt. If you are choosing between the two for a fall trip, our Caribbean hurricane season guide and our cheapest time to visit the Caribbean breakdown are useful companions for comparing the risk and the pricing side by side.

FAQ

What is the best month to visit Costa Rica?

February is often considered the single best month, with the driest, sunniest weather of the year on the Pacific coast. For the best mix of weather and value, late November and May are hard to beat.

Costa Rica's rainy (green) season runs from May through November, with September and October being the wettest months on the Pacific coast. Rain typically falls in the afternoon and evening, leaving mornings clear.

The Bottom Line

The best time to visit Costa Rica is the dry season, December to April, if reliable Pacific-coast sunshine is your top priority. If you care about value, target May or late November to mid-December for near-dry-season weather without peak pricing. And if your only open dates are September or October, lean toward the Caribbean coast, where the weather often flips to its sunniest just as the Pacific side gets soaked.
