Is Visiting Arenal in July & August a Good Idea?

As hosts, one of the most common questions we get is about visiting during Costa Rica's green season. We love this time of year, and we're always excited to share just how special it can be.

Yes, visiting Arenal in July and August is a fantastic idea, especially if you love lush landscapes and fewer people. You can expect bright, sunny mornings perfect for hiking and exploring, followed by afternoon showers that cool everything down and create a cozy atmosphere for relaxing in a hot spring or enjoying a coffee on a covered deck.

What is the "Green Season" in Arenal?

First, let's clear up a common misconception. The "green season" (roughly May through November) isn't a non-stop, weeks-long monsoon. Here in the Arenal area, it’s more of a predictable daily pattern. The landscape transforms into an impossible shade of green, fed by these life-giving rains. It’s a sensory experience—the smell of wet earth, the sound of rain on the roof, the jungle buzzing with life.

July and August often bring a delightful quirk known as the veranillo de San Juan, or "little summer." This is a period of a few weeks when the rains can lessen, giving us a welcome spell of drier weather right in the middle of the green season. There's no guarantee, but it’s a pleasant surprise when it happens.

Here’s a quick comparison to help you decide:

Green Season (July & August)	Dry Season (December - April)
Vibrant, lush green landscapes. Waterfalls are full and powerful.	Drier, browner landscapes. Some smaller waterfalls may be reduced to a trickle.
Predictable pattern: sunny mornings, afternoon showers.	Mostly sunny all day, with less chance of rain.
Fewer visitors on trails and at attractions. A more tranquil experience.	Peak tourist season. Can be crowded at popular spots.
Wildlife is very active, especially amphibians, reptiles, and insects.	Wildlife can be concentrated around remaining water sources, which can be good for spotting.
Volcano views are most likely in the early morning before clouds roll in.	Generally clearer skies offer more consistent volcano views throughout the day.

A Typical Day's Weather in July & August

Understanding the daily rhythm is the key to loving a green season visit. While every day is different, a typical day in July or August near Arenal unfolds like this:

• 6:00 AM - 12:00 PM: The sun is out, the sky is often blue, and the air is fresh. This is the prime time for your big adventures: hiking in Arenal Volcano National Park, crossing the Mistico Arenal Hanging Bridges Park, or going for a horseback ride.
• 12:00 PM - 2:00 PM: You’ll notice clouds starting to gather around the volcano's peak and over the hills. The humidity builds. This is a great time to be finishing your morning activity and heading for lunch at a local soda.
• 2:00 PM - 5:00 PM: The rain arrives. It might be a short, intense downpour or a steady, gentle rain that lasts a few hours. This is your cue to switch to relaxation mode or a rain-friendly activity.
• 5:00 PM onwards: Often, the rain clears up by late afternoon, leaving behind a cool, fresh evening perfect for dinner and listening to the chorus of frogs.

Our Favorite Green Season Activities

The beauty of the green season is that it doesn't stop you from doing things; it just encourages a different pace. We always tell our guests to plan their biggest outdoor activities for the morning and save the afternoons for things that are even better with a little rain.

Morning Adventures (7 AM - 1 PM)

• Hanging Bridges: Walking through the rainforest canopy at a place like Mistico Arenal Hanging Bridges Park or Sky Adventures Arenal Park is magical in the morning light. The forest is misty and alive with birds. For a detailed comparison, check out our family guide to Arenal's hanging bridges.
• Volcano Hiking: The trails at Arenal 1968 or within the national park offer the best chance of seeing the volcano's peak before the afternoon clouds arrive.
• La Fortuna Waterfall: Go early to beat the crowds and enjoy the powerful cascade, which is at its most impressive during the rainy months.

Rainy Afternoon Delights (2 PM onwards)

• Hot Springs: This is the absolute best rainy-day activity. Soaking in naturally heated mineral water while cool raindrops fall around you is pure bliss. From the luxurious The Springs Resort & Spa to the more rustic Ecotermales Fortuna, there's a hot spring for every budget. We have a whole guide to the area's hot springs.
• Caving: The weather above ground is irrelevant when you're exploring the ancient, subterranean world of the Venado Caves. It's a short drive from the Venado area and a perfect adventure for a wet afternoon.
• Farm & Food Experiences: Rainy afternoons are ideal for hands-on cultural activities. We can help arrange a visit to a nearby family farm where you can learn to make cheese or press your own tortillas. It’s a wonderful, authentic experience and a great activity for families.

Celebrating Guanacaste Day (July 25th)

If your visit falls in late July, you're in for a treat. July 25th is Guanacaste Day, a national holiday celebrating the day the Guanacaste province chose to become part of Costa Rica. While the main festivities are in that province, the spirit of celebration spreads across the country.

In towns like La Fortuna, you might encounter:

• Parades: Schoolchildren in traditional outfits, colorfully decorated ox-carts, and local marching bands.
• Music & Dancing: Traditional folk music and dancing in the town square.
• Rodeos & Horse Parades: Known as topes, these are a huge part of local culture.
• Special Foods: Look for street vendors selling traditional corn-based treats and other festival foods.

It’s a vibrant, noisy, and joyful glimpse into local Tico culture that most tourists miss.

What to Pack for Arenal in July & August

Packing smart makes all the difference for a green season trip. The key is layers and quick-drying materials. You can find more detail in our guide on what to pack for Costa Rica's green season, but here are the essentials.

• A good rain jacket: Non-negotiable. Make it a lightweight, breathable, and truly waterproof one.
• Quick-drying clothes: Synthetic fabrics or merino wool are better than cotton, which stays wet forever. Think hiking pants, not jeans.
• Waterproof footwear: A pair of hiking shoes with good grip that can handle mud. A second pair of open-toed, waterproof sandals (like Keens or Chacos) is also a great idea.
• A warm layer: A fleece or light sweater for cool, rainy evenings on the deck.
• Insect repellent: Mosquitoes are more present after the rains.
• A dry bag: A small waterproof bag is invaluable for protecting your phone, camera, and passport during downpours or on boat tours.

The Honest Downsides (and How to Embrace Them)

We believe in setting realistic expectations. So, are there any downsides? Of course, but they are all manageable with the right mindset.

• The Rain: It will rain. If you see rain as a trip-ruiner, the dry season is a better fit. But if you see it as part of the authentic rainforest experience, you'll have a wonderful time. It’s an excuse to slow down. Check out our favorite rainy day activities for more inspiration.
• Cloudy Volcano: The iconic cone of Arenal Volcano may be shy, especially in the afternoons. Your best bet for a clear view is to wake up early. The view from our deck at Casa Venado is ever-changing, and watching the clouds swirl around the peak is its own kind of beautiful.
• Mud: Trails can be muddy. This is part of the adventure! Just bring the right shoes and be prepared to get a little dirty.
• Driving: Roads can be slick. We always advise guests to drive cautiously, allow extra time, and rely on Waze for navigation. A 4x4 isn't strictly necessary for main highways, but it provides much better peace of mind for exploring. We break it all down in our guide to renting a car in Costa Rica.

So, is visiting Arenal in July or August a good idea? For the traveler who appreciates nature in its most vibrant state, who enjoys a bit of quiet, and who sees an afternoon rain shower as a chance to relax rather than a canceled plan, the answer is a resounding yes.

It’s a time to see Costa Rica breathe. If that sounds like your kind of adventure, we’d love to welcome you. We’re always here to help you plan the perfect green season itinerary.
