La Fortuna in July (2026): The Veranillo, Green Season Rain & Family Crowds

⭐ Best July window: roughly July 10 to 24. This is when the veranillo most often lands, and it usually falls just before the Guanacaste Day weekend of July 25 adds domestic travellers to the mix. Book flexible activities so you can chase a clear morning if one arrives.

💰 Average July hotel prices (La Fortuna town, mid-range):
~$110–160/night across the month, firming slightly around the Guanacaste Day weekend (July 25)
Rough mid-range estimates; rates vary by property and booking lead time.

July is the month that refuses to sit neatly in either season. On paper it is deep green season: 345mm of rain, the second-wettest month of the year, with Arenal spending much of its time under a cloud cap. In practice it also hosts the veranillo, the "little summer," a mid-month interruption to the rains that can deliver a week or two of brighter, drier days. In our view that combination makes July more of a gamble than either the dry season or the reliably soaked months of September and October.

The other thing that sets July apart is who is here. June is quiet and cheap; July is neither, because northern-hemisphere school holidays bring families back. So you pay more than June and get more rain, which sounds like a poor deal until you see what the rain does: the La Fortuna Waterfall at full roar, rivers high enough to make rafting genuinely exciting, and rainforest so saturated with green it barely photographs. We'd book July if the waterfall, wildlife and adventure side of La Fortuna matters more to you than a clean postcard of the cone. Our La Fortuna Waterfall guide and rafting guide cover the two experiences July serves best.

Temperature and Humidity

Temperature is the least interesting part of a La Fortuna July, and that is genuinely good news. Days sit around 30°C (86°F) and nights near 21°C (71°F), essentially the same as January, so you pack the same clothes whatever month you come. What changes is humidity, which is high through the green season and makes 30°C feel warmer and stickier than the identical number in February. Quick-dry fabrics matter more than warm ones. The UV index stays very high even on grey days, so sunscreen is not optional just because the sky is overcast.

Rain Pattern

July averages around 345mm of rain, more than double January and second only to October. The pattern is the classic green-season shape: mornings that begin dry or lightly clouded, building heat through late morning, and rain arriving from early to mid-afternoon, sometimes as a heavy hour-long burst and sometimes as a long steady soak into the evening. Most guests find that the mornings are the usable half of the day almost regardless of how wet the month feels overall. Build your itinerary around that and July works far better than the rainfall total suggests.

The Veranillo

The veranillo, literally "little summer," is a well-known break in the Costa Rican rainy season that typically falls somewhere in mid-July. During it, the trade wind pattern shifts enough to suppress the usual afternoon convection, and you can get several consecutive days of bright mornings, lighter or absent afternoon rain, and better volcano visibility than the month's average would imply. Be clear-eyed about it: the veranillo is a tendency, not a scheduled event. Some years it is pronounced and lasts two weeks; some years it barely registers or arrives early or late. The biggest difference between a great July trip and an average one is often just whether your dates happened to intersect it.

Volcano Visibility and Trail Conditions

Arenal sits under cloud far more often in July than in the dry months, and we would call visibility fair rather than good. The reliable window is still sunrise to mid-morning, before daytime heating builds the cloud cap, with an occasional second clearing near sunset. Trails are a different story: the lava field, waterfall staircase and hanging-bridge circuits are all wetter and more slippery than in dry season. None of them become impassable, but proper footwear with grip stops being a nicety and starts being the difference between a good day and a nervous one.

Here is July's genuine oddity: it is wetter than June and also busier and more expensive. That combination catches a lot of travellers out.

• July 1 to 9: the northern-hemisphere school holidays are ramping up and family bookings start to fill the popular tours. Rates have already stepped above June levels, but availability is still comfortable a few days out.
• July 10 to 24: the busiest stretch of the month, and also the window where the veranillo most often lands. Book hotels and headline tours ahead rather than on arrival.
• July 25 to 31 (Guanacaste Day onward): the July 25 holiday adds Costa Rican domestic travellers to the international mix for the long weekend, then the month tails off.

Mid-range hotels in La Fortuna town run roughly $110 to $160 a night through July. That is meaningfully above the $95 to $140 of June and well under the $130 to $200 of a settled January, so July sits squarely in the middle of the year for value while sitting near the top for rainfall. Our take: if your dates are flexible and the school calendar does not bind you, June gives you nearly the same rainforest experience for less money and with fewer people. If you are travelling with school-age children, July is your window and it is a perfectly good one, provided you plan mornings hard.

Our June guide and August guide lay out the two months either side if you have room to move your dates.

Arenal is the reason most people come to La Fortuna, and July is not the month it performs best. We rate visibility fair, around 6 out of 10: better than the September and October low point, considerably short of the near-guaranteed clear mornings of January through March. The volcano generates its own weather, and in a month with 345mm of rain the summit spends a lot of its time wrapped in cloud.

The pattern is still worth planning around. Sunrise to mid-morning is your best window, before the day's heating drives cloud up around the cone. There is often a second, briefer clearing near sunset. What typically happens in July is a partial reveal rather than a clean postcard: the base and mid-slopes visible with the summit in cloud, which is atmospheric in its own right but not what the brochures show. We'd lean toward giving the volcano three separate early mornings across a July stay rather than the two we would suggest in dry season, simply because the odds per attempt are lower.

If the veranillo lands during your trip, this is where you feel it most: a run of clear mornings in mid-July can look a lot like February. Chase it if it arrives, and keep at least one flexible morning in the itinerary so you can move the volcano hike to a clear day. Note that Arenal has been in a resting phase since 2010, so there is no visible lava at night in any month. Our Arenal Volcano hike guide compares the trails and viewpoints, and the hanging bridges offer the other main open vantage point.

A lot, and it is worth being direct about that. July averages roughly 345mm, more than double January's 150mm and behind only October's 375mm across the whole year. La Fortuna sits on the Caribbean-facing slope, where trade winds push moisture against the mountains year-round, and in green season that mechanism runs at full tilt. Anyone telling you July is a dry month has confused it with the Pacific coast a few hours away.

What that number does not tell you is the shape of the day. July rain concentrates in the afternoon and evening. Mornings are frequently dry or only lightly clouded, and that is when nearly every outdoor activity in La Fortuna should happen. Add the veranillo, which can flatten the afternoon rain for a week or two mid-month, and the practical experience of July is much better than 345mm sounds. We think the tradeoff is straightforward: you accept losing most afternoons to rain, and in return you get the waterfall at full volume, high rivers, and a rainforest that is genuinely spectacular rather than merely green.

Three practical consequences. First, pack seriously for wet: a proper rain jacket, quick-dry clothing, a dry bag for camera and phone, and shoes with real grip for the waterfall stairs and muddy trails. Second, front-load everything outdoor into the morning and reserve afternoons for hot springs, coffee tours and cooking classes, all of which are unaffected by rain. Third, build one buffer day into your stay if you can, so a washed-out afternoon does not cost you the activity you cared about most.

The single most useful thing to understand about La Fortuna's climate is that temperature barely moves all year, while rainfall swings roughly fivefold. Daytime highs sit between 29 and 32°C every month and nights hover around 21°C, so you pack the same clothes in January as in July. What actually changes your trip is how much rain falls, and when.

Full Month-by-Month Figures

What the Numbers Actually Mean

Three things stand out. First, March and April are the driest months by a wide margin, at roughly 70 to 75mm, which is why the dry season peaks then rather than in December. Second, October is the wettest at around 375mm, five times March, with September close behind. Third, the shoulder months do most of the work for value travelers: May and November sit between the extremes, offering greener rainforest and lower prices without the full weight of the wet season.

The temperature column is almost a flat line, and that is the point. Most people don't realize that choosing when to visit La Fortuna is a decision about rain and cloud, not about heat. If you want the volcano visible and the trails firm, come in the dry season. If you want thundering waterfalls, fuller rivers, and lower rates, the green season delivers, and you accept afternoon rain as the price.

ℹ️ Figures are rounded monthly averages from a single climate dataset and are indicative rather than exact. Published figures for La Fortuna vary noticeably between sources and weather stations, particularly for rainfall totals and rain-day counts, because the town sits on the Caribbean slope where conditions shift over short distances. Treat these as the shape of the year rather than a forecast.

Beyond the headline tours, July's wet, green conditions favour a particular set of smaller outings:

• Free hot springs at the Tabacón river bridge, thermal water running under the road, and a soak that only improves when it is raining on you.
• Frog and butterfly gardens, small sheltered wildlife stops that are at their liveliest in the wet season and make ideal afternoon fillers.
• Birdwatching around the Peñas Blancas river valley, quieter than in dry season but rewarding in the early morning before the rain.
• Lake Arenal viewpoints and the dam road, a self-drive that still works under cloud, with dramatic moody skies over the water.
• El Salto rope swing, the local river swimming hole, running high and fast in July; check conditions and skip it after heavy rain.
• La Fortuna central park and church, an easy evening stroll between showers, with cafés and sodas to duck into.
• Chocolate and cacao workshops, indoor, hands-on and completely immune to the forecast.

July has one fixed national date and one weather event that behaves like an event.

• Guanacaste Day (July 25): a national public holiday marking the 1824 annexation of the Guanacaste province, celebrated most vividly in Guanacaste itself with parades, folk dancing and rodeos. In La Fortuna the effect is indirect but real: Costa Rican families travel over the long weekend, so roads, hotels and popular tours are busier than the surrounding weeks.
• The veranillo (roughly mid-July): not a holiday, but the month's defining feature. This short dry spell can hand you several consecutive bright mornings in the middle of green season. Its timing and strength vary considerably from year to year, so plan for rain and treat clear days as a bonus.
• Northern-hemisphere school holidays: also not an event, but the reason July feels busier and costs more than June despite the extra rain.

None of this needs to change your itinerary, but if your dates straddle July 25, book accommodation and any headline tour earlier than you otherwise would.

• Do everything outdoors in the morning. July rain concentrates in the afternoon and evening, so a 7 AM start is not about beating crowds here, it is about beating the weather.
• Do not build your trip around the veranillo. The mid-July dry spell is a tendency, not a guarantee, and its dates shift every year. Plan for a wet month and enjoy the clear run if it arrives.
• Keep one flexible morning for the volcano. Visibility is only fair in July, so give Arenal three separate early attempts across your stay rather than pinning it to a single booked day.
• Pack real rain gear. A proper jacket, quick-dry layers, a dry bag for electronics, and shoes with genuine grip. The waterfall staircase is about 500 steps each way and slick in green season.
• Book ahead around July 25. Guanacaste Day brings domestic travellers, and combined with school-holiday visitors it makes the last week the tightest of the month for availability.
• Lean into the water. The waterfall, rafting and canyoning are all better now than in dry season. If you are going to get wet regardless, choose the activities that reward it.
• Save hot springs, coffee tours and cooking classes for afternoons. They are effectively rain-proof and pair perfectly with a morning outdoors.
• Check Rio Celeste conditions before you drive. Heavy rain can dull the river's famous blue, and it is a long round trip from town.
• Add a buffer day. One extra day in La Fortuna gives you a second shot at anything a storm ruins, which matters more in July than in February.
• Visiting at a different time of year? See our La Fortuna in June guide for a quieter, cheaper green-season month, and our La Fortuna in August guide for the month that follows with similar crowds and slightly less rain.
