In Brief
When is the best time to visit Costa Rica?
The best time to visit Costa Rica is the dry season, roughly mid-December to April, when the Pacific coast and northern lowlands are sunny and rainfall is lowest - ideal for beaches and wildlife spotting. This is also the busiest and priciest window, especially around Christmas-New Year and Easter (Semana Santa). For lush scenery, thinner crowds and lower prices, come in the green season (May to mid-November), with May-June and November offering the best balance of decent weather and value.
Key takeaways
- Best weather: mid-December to April - dry, sunny days across the Pacific and Central Valley.
- Cheapest months: May, June and November, when green-season rates and low crowds return.
- Highlight: humpback whales off the south Pacific roughly July to October, plus turtle nesting on both coasts.
- Avoid (for beaches): September and October are the wettest on the Pacific, though the Caribbean side stays drier.

Costa Rica month by month
Every month rated for weather, crowds and price, so you can match the trip to the month.
| Month | Weather | Crowds | Price | What it's like |
|---|---|---|---|---|
| Jan | 21–31°C, dry, sunny | Peak | $$$ | Prime dry-season weather with sunny days and low humidity; crowds and prices stay high after the New Year holiday. |
| Feb | 21–32°C, dry | High | $$$ | One of the driest, sunniest months - excellent for beaches and wildlife, and still firmly in peak season. |
| Mar | 22–33°C, dry, hot | High | $$$ | Hot and dry, with the Pacific at its driest; Easter week (Semana Santa) can fall late in the month and spikes domestic travel. |
| Apr | 22–33°C, dry, warm | Moderate | $$ | The dry season winds down and the first rains may arrive late; early April is great value once Easter passes. |
| May | 22–31°C, afternoon rain | Low | $ | The green season begins with lush landscapes and mostly sunny mornings; prices drop and crowds thin - strong value. |
| Jun | 21–30°C, afternoon rain | Low | $ | Wet afternoons but bright mornings and vivid greenery; low prices make this one of the best-value months. |
| Jul | 21–30°C, mixed | Moderate | $$ | A brief drier spell (veranillo) often lifts the Pacific mid-summer, and humpback whales start arriving in the south. |
| Aug | 21–30°C, afternoon rain | Moderate | $$ | Green and warm with regular afternoon showers; whale watching continues off the south Pacific coast. |
| Sep | 21–29°C, wet | Low | $ | The wettest month on the Pacific and Central Valley - but the Caribbean side is often drier and sunnier now. |
| Oct | 21–29°C, wettest | Low | $ | Peak rains on the Pacific with some roads and tours affected; the Caribbean coast is a notable dry-weather exception. |
| Nov | 21–30°C, easing rain | Low | $ | Rains taper off through the month as the dry season returns; lush scenery with low crowds and prices - excellent value. |
| Dec | 21–31°C, drying out | Low then Peak | $$ | Early December is dry and quiet; crowds and prices surge from around Dec 20 for the Christmas-New Year peak. |
When to book Costa Rica
On the table above, May, Jun, Sep, Oct and Nov sit in the bottom price band and Jan, Feb and Mar in the top one. Find the row that sounds like your trip.
| If you want | Months | Why |
|---|---|---|
| The best trip for the money | Apr, Jul and Dec | Rated good above without hitting the top price band, so you are not paying peak rates for the conditions. |
| The lowest price, whatever the weather | May, Jun, Sep, Oct and Nov | The bottom price band. Check the weather column first, because some of these are cheap for a reason. |
| Peak season anyway | Jan, Feb and Mar | Busiest and dearest. This is the window where booking early changes the price, not just what is left. |
| To know what to skip | Sep and Oct | Rated off-peak here. The low price is the compensation, not a bargain. |
