Check the live forecast above for your travel window, then plan around Costa Rica’s two distinct seasons: the dry season (December to April) is best for beach trips and wildlife viewing, while the green season (May to November) offers lower rates and fewer crowds.

What is the best time to visit Costa Rica for Canadian travellers?

The dry season, from mid-December through April, aligns perfectly with March break and snowbird travel. This is when you’ll find the most reliable sunshine on the Pacific coast, in Guanacaste, and around Santa Teresa. For inland destinations like La Fortuna and Monteverde, the dry season also means clearer views of volcanoes and cloud forests. If you’re flexible, the shoulder months of November and May deliver good weather and better value on flights and lodging.

What should I pack for Costa Rica’s weather?

Pack for both heat and rain, regardless of season. Lightweight, quick-dry clothing, a rain jacket, and sturdy walking shoes are essentials. In the highlands—Monteverde and the Central Valley—temperatures can drop to 15°C, so bring a fleece or sweater. For the coast and lowlands, expect 27°C to 32°C year-round. Sunscreen, insect repellent, and a reusable water bottle will serve you well from San José to the beaches.

Frequently asked questions about Costa Rica weather

What is the weather in Costa Rica like in March?

March falls in the heart of the dry season. Expect sunny days across most regions, with coastal highs near 32°C and cooler evenings in Monteverde and La Fortuna. It’s a top month for Canadian March-break travellers.

Does it rain every day in the green season?

Not every day, but afternoon showers are common, especially from September to November. Mornings are often clear, making it a good time for hiking or wildlife tours. The Caribbean coast tends to be wetter year-round.

How accurate are 14-day Costa Rica weather forecasts?

For a destination with microclimates, a 14-day forecast gives a general trend rather than precise daily conditions. Check the live forecast above and a reliable 10-day outlook closer to your trip for the most useful guidance.
