Nosara is a laid-back surf and yoga town on Costa Rica's Nicoya Peninsula, one of only five Blue Zones on the planet where locals routinely live past 100. The pace here moves with the tide: mornings start with sunrise yoga in open-air shalas overlooking the jungle, afternoons center on Playa Guiones and its mile-long crescent of ivory sand where surfers of every level catch consistent breaks year-round. Just 20 minutes up the coast, the Ostional National Wildlife Refuge hosts one of Earth's most extraordinary spectacles, the olive ridley sea turtle arribada, when hundreds of thousands of turtles crawl ashore to nest. Between the wildlife sanctuaries, the mangrove kayaking, the farm-to-table restaurants like La Luna perched above the beach, and the community's Saturday morning farmers market, Nosara rewards travelers who want to slow down and connect with nature rather than check off a highlight reel.
The best time to visit Nosara is late November through late April, when dry skies, warm temperatures, and the full calendar of cultural events align. This window covers the heart of the dry season, meaning virtually no rain from December through March, comfortable humidity, and the liveliest stretch of the year for music festivals, yoga retreats, and the Fiestas Patronales celebration in January. If you want to witness the massive olive ridley turtle arribadas at Ostional, plan for September or October instead, accepting heavier rain in exchange for a once-in-a-lifetime wildlife experience. Budget-conscious travelers will find May and November offer shoulder-season pricing with tolerable weather on the edges of the rainy season.
Spring in Nosara, Costa Rica
April in Nosara still carries the tail end of dry season energy. Highs climb to 95.2°F (35.1°C), making this one of the hottest stretches of the year, but steady ocean breezes along Playa Guiones keep beach time enjoyable. Mid-April brings peak heat, with highs reaching 97.1°F (36.2°C) and overnight lows around 72.4°F (22.4°C), so plan surf sessions and hikes in the Nosara Biological Reserve for early morning before the sun intensifies. The mid-April holiday of Juan Santamaría Day and Easter week (Semana Santa) draw local vacationers to the coast, so book accommodations in advance if your trip overlaps.
By May, the landscape begins to transform. Rain chances jump to around 26%, mostly as afternoon showers that leave mornings clear. Lows settle to a comfortable 72.1°F (22.3°C), and the jungle greens up almost overnight. Surf conditions actually improve as southern swells pick up, making this a rewarding month for wave riders who don't mind dodging a thunderstorm. Crowds thin noticeably after Easter, and you'll find more availability at popular yoga studios like Bodhi Tree and the Harmony Hotel. Pack a light rain jacket alongside your reef-safe sunscreen, and plan outdoor adventures for the morning hours when skies are clearest.
Summer in Nosara, Costa Rica
The green season settles in fully from June through August, and Nosara transforms into a lush, quieter version of itself. Highs average 91.1°F (32.8°C) with lows around 73.4°F (23°C), and humidity climbs into the 60s and high 60s. Afternoon rain becomes a regular pattern, with roughly 3 to 5 significant rain days per month, but mornings typically stay clear enough for a sunrise surf session or a kayak through the mangroves along the Nosara River, where you can spot crocodiles, herons, and howler monkeys in the canopy overhead.
This is when surfers take over. Consistent swells from the south produce some of the best waves of the year at Playa Guiones, and the lineups are far less crowded than in winter. Tourism slows considerably, and accommodation prices dip, making it an appealing window for budget-minded travelers. Late July brings the Annexation of Guanacaste celebration on July 25, a regional holiday marked by marimba music, traditional dances, and parades in the nearby towns. Turtle nesting season also begins ramping up at Ostional, with smaller arribadas starting in July and growing through August. Pack quick-dry clothing and waterproof bags for your electronics, and embrace the rhythm of sunny mornings followed by dramatic tropical downpours.
Fall in Nosara, Costa Rica
Fall is the quietest and wettest stretch in Nosara. September is the rainiest month, with significant precipitation on roughly half the days, and October follows close behind at 46%. Highs ease to 89°F (31.7°C) and lows sit at 71.9°F (22.2°C), a modest relief from the heat of spring. Humidity peaks in October, so expect muggy conditions, especially in the afternoons. Some unpaved roads on the Nicoya Peninsula can become challenging during heavy rains, so a 4x4 rental is advisable if you plan to explore beyond town.
The payoff for braving the rain is extraordinary wildlife. September and October bring the largest olive ridley arribadas at Ostional, when hundreds of thousands of turtles crawl ashore to nest over the span of a few days, typically around the new moon. It's one of the most dramatic wildlife spectacles on the planet, and seeing it from just 20 minutes outside Nosara justifies the soggy conditions. Costa Rica's Independence Day falls in mid-September, which you may notice through closures and local celebrations. By November, the rains begin to taper, dropping to around 16% chance of significant precipitation. The landscape is at peak green, waterfalls like Mala Noche are running strong, and you'll practically have the yoga studios and beach restaurants to yourself. Accommodation prices sit at their lowest, and you can often book last-minute without trouble.
Winter in Nosara, Costa Rica
December through March is Nosara's marquee season. Dry skies return, with January, February, and March recording virtually 0% chance of significant rain. Highs average 92.4°F (33.6°C) and lows dip to 69.8°F (21°C), making evenings pleasant enough to linger at beachside spots like La Luna, where sunset dinner on the sand is a local ritual. The steady trade winds that blow through January and February (peaking near 12.6 mph) keep the heat manageable and add texture to the surf at Playa Guiones.
This is when Nosara's social calendar hits its peak. January kicks off with the Fiestas Patronales, a weeklong celebration of bull riding, marimba music, parades, and food stalls that draws the entire community together. The Nosara Music Festival follows around January or February, an open-air gathering near Playa Guiones featuring Latin jazz, reggae, and world music alongside food vendors and yoga sessions. The Saturday morning farmers market is at its liveliest, with organic tropical fruit, fresh bread, artisanal crafts, and live music under the trees. Wildlife sanctuaries like Sibu and International Animal Rescue run regular tours, and the Nosara Biological Reserve is ideal for early morning bird walks through the dry tropical forest, home to over 270 species.
The tradeoff is crowds. March is the busiest month, and December and February are close behind, so book well in advance, especially during Christmas week and Semana Santa. Restaurants like the Gilded Iguana, known for live music evenings, fill up quickly, and yoga retreat spaces at Bodhi Tree and Harmony Hotel sell out weeks ahead. Bring light, breathable clothing, a good hat, and reef-safe sunscreen; you'll spend most of your time outdoors.

Travel Tips & Safety for Nosara, Costa Rica
Most visitors fly into Guanacaste Airport in Liberia (LIR), about two and a half hours from Nosara by car. The regional airline Sansa also operates short flights directly to Nosara's small airstrip, cutting travel time to roughly 30 minutes. Renting a car gives you freedom to explore the peninsula, but a 4x4 is strongly recommended, as the roads leading into Nosara are unpaved and can be rough, especially in the rainy months. If you're staying in the main Guiones area, you can get around on foot or by golf cart, a popular local option.
Nosara is generally a safe destination, but take standard precautions: don't leave valuables unattended on the beach, use hotel safes, and be cautious driving at night on unlit rural roads where animals sometimes cross. Ocean currents at Playa Guiones can be strong, so swim near other people and heed local advice about rip currents, particularly during the rainy season when swells increase. Tap water is safe to drink throughout Costa Rica.
