The short answer to when to visit Costa Rica is the dry season — broadly January–April, December. That’s when the rain holds off, the trails dry out, and the adventure, nature, beach side of Costa Rica shows up most consistently. The longer answer is more nuanced: there are sweet spots inside the dry months (shoulder weeks before peak hit) and there are individual rainy-season weeks where the trade-off works in your favour — fewer crowds, lower prices, and the kind of green-everywhere photography you only get when the wet season has just broken.

Sweet Spots
If you’re optimizing for the trade-off between weather, crowds, and price, the strongest weeks tend to be at the edges of the best-month window — the first half of January and the last weeks of December. Peak weather is locked in but the Costa Rica of those bookend weeks isn’t yet (or no longer) at full tourist capacity. Local festivals and the post-rain green-everywhere window are bonus signals to chase.
When to Avoid (and the Exceptions)
If you can flex your dates, the months that consistently disappoint most Costa Rica travellers are May–July. That said, off-season has its compensations — the obvious one is price (accommodation can drop 30–50%), the subtle one is what locals call the ‘real’ version of the place: no queues, no tour buses, and everyday life running at its actual pace.
