When is the best time to visit Costa Rica?
There's no bad month in the tropics — only different kinds of magic. Here's an honest, local's breakdown of the seasons, the weather by region, and how to match your travel dates to the trip you're dreaming of.
- Dec–Apr — Dry Season
- May–Nov — Green Season
- 70–90°F — Year-round
The short answer
The best time to visit Costa Rica is the dry season, from mid-December through April, when sunshine, calm seas and easy road conditions make it ideal for beaches, surfing and family travel. The green season (May–November) trades occasional afternoon rain for lush, emerald landscapes, dramatic waterfalls, thinner crowds and noticeably lower prices — making it the smart choice for budget-minded travelers, nature lovers and photographers. Wildlife is exceptional year-round.
Dry season vs. green season
Costa Rica doesn't have summer and winter — it has dry and green. Understanding the trade-off between them is the single most useful thing for planning your trip.
Dry Season · Mid-Dec to April
- Reliable sunshine and blue skies, especially on the Pacific coast
- Best conditions for beaches, snorkeling and catamaran days
- Easy driving — dirt roads to remote lodges stay firm
- Peak wildlife visibility as animals gather near water
- The liveliest atmosphere; festivals and high-season energy
Trade-off: highest prices and busiest beaches — book 4–6 months ahead, especially Dec 20–Jan 5 and Easter week.
Green Season · May to November
- Landscapes at their most lush — rainforests glow emerald
- Waterfalls and rivers run full and spectacular
- Fewer travelers; you'll have trails and beaches to yourself
- Lower lodging and tour prices — better value across the board
- Mornings are typically bright; rain often comes as a warm afternoon shower
Trade-off: September–October are the wettest on the Pacific (but prime for the Caribbean & turtle nesting).

Bright mornings, afternoon showers. Turtle nesting starts on the Caribbean coast.
The "little summer" — a sunny dry spell mid-season. A local secret for great weather and value.
Lush and lively. Humpback whales peak in the South Pacific around Uvita.
Wettest on the Pacific, but the Caribbean shines — and turtle nesting is at its height.
Quietest month. Dramatic skies, roaring waterfalls, lowest prices — a photographer's dream.

Weather by region
Costa Rica fits a dozen microclimates into one small country. The "rainy season" looks completely different depending on which coast you're standing on.
| Region | Driest & best | Wettest | Why go |
|---|---|---|---|
| Guanacaste & North Pacific | Dec–Apr | Sep–Oct | Most reliable sunshine and the country's best beaches |
| Central Pacific (Manuel Antonio) | Dec–Apr | Sep–Oct | Beaches + rainforest + easy wildlife, close to San José |
| Arenal & Northern Plains | Feb–Apr | Sep–Nov | Volcano, hot springs and waterfalls — green almost year-round |
| Monteverde Cloud Forest | Jan–Apr | Sep–Oct | Misty, cool and magical — bring a light layer any month |
| Caribbean (Tortuguero, Puerto Viejo) | Feb–Mar & Sep–Oct | Nov–Jan | Bucks the trend — driest when the Pacific is wettest |
| South Pacific (Osa, Corcovado) | Dec–Apr | Sep–Nov | Wildest rainforest and humpback whale season |
Local tip: Heading out in September or October? Pair a lush Arenal–Monteverde route with the Caribbean coast, which enjoys some of its best weather exactly then.

Best-time FAQs
What is the cheapest time to visit Costa Rica?
The green season — especially May, June, September and October — offers the lowest prices on flights, hotels and tours. September and October are the quietest and most affordable, with discounts of 20–40% common at many lodges compared to the December–April peak.
Does it rain all day during the green season?
Rarely. Most green-season days start bright and sunny, with rain arriving as a warm, refreshing shower in the afternoon or evening — often over in an hour or two. You can comfortably plan morning tours and beach time around it. The far wetter stretch is September–October on the Pacific side.
When is the best time to visit for wildlife?
Honestly, any time. The dry season (December–April) concentrates animals around rivers and waterholes, making them easier to spot, while the green season brings turtle nesting, whale watching and lush conditions for frogs, insects and birds. Tell us what you most want to see and we'll time your trip around it.
What is the rainiest month in Costa Rica?
October is generally the wettest month on the Pacific and Central regions. The Caribbean coast, however, is an exception — it often enjoys some of its driest, sunniest weather in September and October.
When should I book to get the best dates?
For dry-season travel (December–April), book 4–6 months ahead — and even earlier for the Christmas/New Year and Easter weeks, when the best lodges sell out first. Green-season trips can often be arranged with much shorter notice.
