Drive into Atenas, Costa Rica, and the claim is unavoidable. It’s painted across the back of local buses, printed on billboards, and even lends its name to a restaurant in town: “Visite Atenas, el mejor clima del mundo,” visit Atenas, the best climate in the world. For a town of roughly 25,000 people tucked into the western edge of the Central Valley, that’s a bold thing to put on a bus. But talk to almost anyone who has spent time there, resident or visitor, and the claim tends to hold up better than most tourism slogans.
Atenas sits in Alajuela province, about 30 minutes from Juan Santamaría International Airport and 45 minutes from downtown San José, at an elevation that puts it in a sweet spot most of atenas Costa Rica’s coastal towns can’t touch: warm enough for shorts and sandals year-round, cool enough that air conditioning is rarely necessary. That combination, along with a walkable town center, a strong expat community, and a surprising range of day trips nearby, has turned Atenas into one of the most talked-about small towns in the country, whether the person talking about it is a retiree comparing it to the Canary Islands or a first-time visitor just passing through on the way to the coast.
This article covers where the “best climate in the world” claim actually comes from, what Atenas’s weather is really like month to month, what there is to do in town and nearby, and the practical details worth knowing before a visit or a move.
Where the “Best Climate in the World” Claim Comes From
The story most commonly repeated is that National Geographic once declared Atenas home to the best climate on Earth. It’s a good story, and it’s the one printed on the buses. The problem is that National Geographic has confirmed it never published any such claim, and no original article naming Atenas as the world’s best climate has ever surfaced.
The more credible origin traces back to the mid-1990s, when a atenas Costa government marketing committee, working to promote the country’s smaller towns, is believed to have coined or popularized the phrase as part of a tourism campaign. Somewhere along the way, the marketing slogan picked up a National Geographic attribution that stuck, repeated so often over three decades that it now reads as established fact.
Whatever its true origin, the phrase has outlived the debate over its source. Locals use it without irony, real estate listings lean on it constantly, and most visitors who spend a few days in Atenas come away agreeing the climate earns the reputation, magazine citation or not.

What Atenas’s Climate Is Actually Like
Setting the marketing claim aside, Atenas’s weather is genuinely unusual for atenas Costa rica , and the explanation comes down to geography. The town sits at an elevation between roughly 600 and 1,200 meters (1,960 to 3,930 feet), positioned at a kind of atmospheric crossroads between Pacific moisture and the volcanic ridges that frame the Central Valley. That setup creates a stable microclimate that avoids the extremes found elsewhere in the country.
Daytime highs typically run 75°F to 85°F (24°C to 29°C) year-round, while nights cool down to a comfortable 60°F to 68°F (16°C to 20°C), cool enough for a light blanket but rarely cold enough to need heating. Compare that to atenas Costa rica Pacific coast, where daytime temperatures regularly push into the 90s°F with humid nights in the high 70s, and the appeal becomes obvious. Atenas also benefits from lower relative humidity than coastal towns, generally in the 60% to 70% range, which makes the heat feel noticeably more comfortable even on the warmest afternoons.
The town follows Costa Rica’s typical two-season pattern: a dry season from December to April, locally called “summer,” bringing consistent sunshine and gentle mountain breezes, and a green season from May to November, with afternoon or evening rain that keeps the surrounding hillsides lush without disrupting daily life.
Unlike many parts of the country, residents describe both seasons as pleasant, since Atenas rarely sees the kind of prolonged downpours or extreme heat that make other regions genuinely uncomfortable during their off-season. The area is sometimes described locally as the sun belt of the Central Valley, sunny enough for pool days most of the year while staying cool enough overnight that a light blanket, not a fan or heater, is all anyone really needs.
Why the Climate Has Made Atenas a Magnet for Expats
Atenas is now the second most expat-populated town in atenas Costa rica, trailing only the San José suburb of Escazú, and roughly 8% of its residents were born abroad. The climate is the headline reason, but it’s rarely the only one. Zero-cooling-cost living is a genuine financial draw, since homes in Atenas rarely need air conditioning, while coastal properties can rack up electricity bills exceeding $400 a month running AC constantly. Atenas has also been named among the world’s best retirement destinations by organizations including International Living and AARP, citing the climate alongside the town’s manageable size, healthcare access, and proximity to San José.
Retirees and remote workers make up a large share of the expat population, drawn by a combination of comfortable year-round weather, a walkable town center, and an easy 30-minute drive to the airport, meaning international flights don’t require the multi-hour drive that many other atenas Costa rica towns do. Real estate in the area has grown steadily as a result, with properties ranging from modest in-town homes to larger hillside estates in developments that trade on the same climate reputation, often citing lower long-term utility costs as part of the pitch to buyers coming from hotter, more humid parts of the country.
Things to Do in Atenas
Atenas rewards travelers who like small-town exploration over packed itineraries, though there’s more to do nearby than the sleepy reputation suggests.
Atenas Central Park anchors the town, lined with Royal palm trees and facing the Parroquia San Rafael Arcángel church, a well-preserved piece of the town’s architectural heritage. It’s a common gathering spot, especially in the evenings, and often hosts free live music, festivals, or dancing.
Coffee farm tours are a signature Atenas activity, since the surrounding hills are dense with coffee plantations. Local farms offer full tours from bean to cup, often ending with a tasting of freshly roasted coffee grown on-site.
Zoo Ave, a non-profit wildlife rescue and rehabilitation center just outside town, cares for more than 130 native species, offering a way to see toucans, macaws, and other Costa Rican wildlife up close in a conservation-focused setting rather than a traditional zoo.
La Garita’s Botanical Orchid Garden showcases a wide variety of native orchid species alongside colorful, indigenous birds, and doubles as a quiet, educational stop for anyone interested in the region’s plant life.
Las Minas Waterfalls, a lesser-known natural spot near an old abandoned gold mine, offers a quieter alternative to Costa Rica’s more crowded waterfall destinations.
The weekly farmer’s market, held Thursday afternoons and Friday mornings, is a good way to sample local produce, street food, and handmade crafts alongside residents doing their regular shopping.
The annual Atenas Fiesta, typically held in April, celebrates the town’s heritage with a roughly four-day festival featuring atenas Costa rica iconic hand-painted oxcarts (carretas), a UNESCO-recognized cultural symbol, along with traditional music, dance, and vendor stalls filling the central park.
Day Trips from Atenas
Atenas’s location in the western Central Valley makes it a convenient base for exploring further afield. The Doka Estate and other nearby coffee plantations offer more in-depth farm tours beyond what’s available in town itself, walking visitors through the full process from picking to roasting. Pacific beaches sit roughly an hour away via Route 27, a modern highway that connects Atenas directly to the coast, San José, and the airport without the winding mountain roads common elsewhere in the country
Poás Volcano and La Paz Waterfall Gardens are also within reach for a full-day excursion, and nearby towns like Grecia and Sarchí, known for their oxcart factories and craft traditions, make for an easy half-day detour. This makes Atenas a workable home base for travelers who want easy access to both the coast and the volcanic highlands without relocating hotels mid-trip.
Is Atenas Worth Visiting or Living In
For travelers, Atenas works best as either a short stopover, given its proximity to the airport, or a slower-paced base for exploring the Central Valley without the crowds found in more heavily touristed towns like La Fortuna or Manuel Antonio. It’s not a beach destination and doesn’t try to be one; the appeal is the climate, the walkability, and the easy day-trip access to everywhere else, which makes it a sensible first or last stop on a longer atenas Costa rica itinerary, especially for travelers with an early flight who’d rather not drive hours from the coast on departure day.
For those considering a longer stay or relocation, Atenas offers a rare combination in Costa Rica: comfortable temperatures without coastal humidity, a manageable cost of living relative to more built-up expat hubs like Escazú, and enough existing English-speaking infrastructure, thanks to the established expat community, that the transition tends to be smoother than in more remote parts of the country.
