That’s why we created this guide. Here you’ll find tips on choosing the right time to visit Arenal based on what you want to see, do, and experience.
When Is the Best Time to Visit Arenal, Costa Rica?
The best time to visit Arenal, Costa Rica, depends on what you want from your trip, but in general, the dry season from December to April is considered the best time to go. During these months, you’ll usually find clearer skies, better views of the Arenal volcano, and more reliable conditions for outdoor activities.
That said, the rainy season from May to November can still be a great time to visit. You’ll see greener landscapes, fewer crowds, and more active wildlife, even if you get some afternoon rain.
How Is Arenal’s Weather Really Like?
The weather in Arenal is more predictable than it might seem at first, but it doesn’t always match what people expect from a typical “dry” or “rainy” season. Arenal sits in Costa Rica’s northern lowlands, which play a big role in how weather patterns develop here. Conditions can also change throughout the day, and understanding how each season behaves will help you plan your time better.
Here’s how the weather changes throughout the year in Arenal:
Dry Season
In the dry season (December through April), Arenal tends to have drier and more stable weather. Days are usually sunny or partly cloudy, with less frequent rainfall and clearer skies in the morning. Temperatures stay warm, and humidity is lower compared to the rest of the year. It’s common to have long stretches of dry days, especially in the earlier months of the season.
Rainy Season
In Arenal’s rainy season (May through November), rainfall becomes more frequent, but it rarely lasts all day. Mornings often start with clear or partly cloudy skies, followed by rain in the afternoon or evening. The landscape becomes noticeably greener, and humidity levels rise. Showers can vary from light rain to heavier downpours, especially in the peak months of September and October.

When to Visit Arenal, Costa Rica for Different Activities
When it comes to activities, the best time to visit Arenal can change depending on what you want to do while you’re here. Weather is an important factor, but so are things like visibility, wildlife activity, and how busy certain places feel throughout the year.
Check out the best times to plan your visit based on the experiences you’re looking for:
Best Time for Clear Volcano Views
If clear views of the volcano are part of your plans, early mornings are your best window any time of year. Skies tend to be clearer before clouds build up later in the day.
The dry season usually brings more consistent visibility, especially from January through April. That said, Arenal Volcano visibility depends on cloud cover, not just the season. Even during drier months, clouds can roll in quickly, while some mornings in the rainy season still offer clear views.
Best Time for Wildlife and Rainforest Experiences

If you’re hoping to see more wildlife and spend time out on the hiking trails, the rainy or green season is when the forest feels most active. From May through November, regular rain brings thicker vegetation and more movement throughout the forest, with more chances to spot monkeys moving through the trees, birds overhead, and frogs near the trails.
These months also bring the most vibrant scenery, with deeper greens and more activity across the rainforest. Walking through areas like Mistico Arenal Hanging Bridges Park during this time gives you a closer look at how the rainforest changes throughout the year.
Best Time for Fewer Crowds
If you’re looking for a quieter experience, the rainy season is usually the best time to plan your visit. Months like May, June, September, and October tend to be less busy across the area.
Try to avoid major holidays and peak travel periods, like Christmas, New Year’s, and Easter week, when Arenal sees more visitors regardless of the season.
Best Time for Lower Prices
If you’re looking to spend less during your trip, the green season is usually the best time to visit. September and October tend to have the lowest prices across hotels and tours, and natural hot springs in the area.
You’ll also find more availability during these months, which makes it easier to book places to stay and plan activities without needing to reserve everything too far in advance.
