Quepos Costa Rica Weather: Climate Guide for Manuel Antonio
Quepos is the gateway town to Manuel Antonio National Park on Costa Rica's Central Pacific coast. Located at sea level about 3 hours south of San José, Quepos enjoys a warm tropical climate year-round with temperatures averaging 82–90°F (28–32°C). The area has a clear dry season from December through April and a pronounced rainy season from May through November, but thanks to its lush surrounding rainforest, Quepos stays green and vibrant in every season.
Quepos and Manuel Antonio Climate Overview
Quepos sits on Costa Rica's Central Pacific coast in a zone that receives significantly more rainfall than Guanacaste to the north but less than the Southern Pacific's Osa Peninsula. Annual rainfall averages 140–160 inches (3,556–4,064 mm), making Quepos one of the wetter locations on the Pacific coast. Despite this total annual rainfall, the dry season (December–April) brings a marked reduction with 1–4 inches per month rather than 15–25 inches during peak rainy season months.
The climate around Quepos is influenced by its position near the transition zone between the drier Central Pacific and the wetter Southern Pacific. Mountains rising immediately inland trap moisture, producing the lush rainforest that makes Manuel Antonio National Park so biologically diverse. The park itself is one of the smallest national parks in Costa Rica but ranks among the world's most biodiverse areas per square kilometer.
Year-round temperatures at Quepos are consistently warm. Daytime highs range from 84–90°F (29–32°C), with the hottest temperatures in March and April and the slightly cooler—though still warm—months being September through November. Overnight lows range from 73–77°F (23–25°C), making the heat the dominant weather experience regardless of season.
Quepos Town vs. Manuel Antonio Beach
Quepos town and Manuel Antonio (the park area) are about 7 kilometers apart, connected by a winding road through the hills. Hotel and residential areas along this road experience slightly different microclimates than the beach level at the park. The hills between Quepos and the park can capture clouds and fog, sometimes producing light rain even on otherwise dry days. Quepos town at sea level is typically slightly drier than the park itself, which sits in a more sheltered position surrounded by forest.
Dry Season Weather in Quepos
December through April brings the most reliably sunny weather to Quepos and Manuel Antonio. While Quepos is never as dry as Guanacaste during this period, the dry season here still means clear mornings, warm temperatures, and significantly reduced afternoon rain probability. January and February are the driest months, averaging 2–4 inches (51–102 mm) for the month—much less than the 15–25 inches of the wet season peak.
The dry season makes Manuel Antonio National Park's trails significantly more navigable. The 0.8-mile (1.3 km) Punta Catedral loop trail, the beach circuits, and the inland forested paths all become drier and less muddy, making wildlife spotting easier and the hiking experience more comfortable. The park's famous beaches—Playa Manuel Antonio, Playa Espadilla Sur, and Playa Biesanz—are calmer and cleaner during the dry season with reduced river runoff.
Ocean conditions at Manuel Antonio's beaches improve significantly in the dry season. Playa Biesanz, a small protected cove within the park accessible only by trail, offers excellent snorkeling in January–April with notably better visibility than the rainy season. The main Playa Manuel Antonio beach has calm waters ideal for swimming, snorkeling near the rocky headlands, and kayaking.
Scarlet Macaws in Dry Season
The dry season is the prime time to observe scarlet macaws near Quepos. These iconic red-and-blue parrots nest in tall trees along the Central Pacific coast from February through June, and the Quepos–Manuel Antonio area is one of the best locations in Costa Rica for macaw viewing. They are most vocal and active in the early morning, and their brilliant plumage is especially visible in the dry season's clear light. Listen for their harsh squawking calls and look for pairs flying in tandem over the forest canopy.
Rainy Season Weather in Quepos
The rainy season (May through November) brings significant rainfall to the Quepos area. Monthly rainfall ranges from 14 inches (356 mm) in May to over 25 inches (635 mm) in September and October—among the heaviest rainfall concentrations on the Pacific coast. However, the area's abundant rainfall is precisely what creates the lush, spectacularly green landscape that makes Manuel Antonio so visually stunning.
Even during the rainiest months, mornings are frequently clear and sunny. The classic pattern—sunny until 10 AM, clouds building by noon, thunderstorms from 2–5 PM, clearing by 6 PM—applies reliably to Quepos in June through August. September and October can see longer-lasting and more intense rain events, sometimes including overnight rain and cloudy days. However, full-sun days still occur regularly even in September.
The rainy season brings remarkable benefits to the Quepos area. Waterfall trails in the surrounding hills and at Nauyaca Waterfalls (one of Costa Rica's most spectacular waterfall destinations, accessible from Dominical with horse or hiking tour) reach their most impressive flow June through October. River kayaking and whitewater rafting on the Naranjo River are most exciting during the rainy season. Wildlife activity in Manuel Antonio peaks during this period, with sloths, monkeys, and tropical birds highly active.
Nauyaca Waterfalls in Rainy Season
The Nauyaca Waterfalls—a stunning double waterfall about an hour from Quepos near Dominical—are at their most spectacular during the rainy season. The 150-foot (46-meter) lower falls and the upper cascade reach peak flow in July through October, creating a thunderous display. The trails to the falls become muddier in the rainy season, so wear waterproof shoes and consider taking a horseback tour (operators run from Dominical). The swimming hole at the base of the falls remains swimmable throughout the rainy season.

Annual Rainfall Summary
Quepos receives approximately 155 inches (3,937 mm) of rain annually—distributed across all months but heavily concentrated in May–November. The average annual temperature is around 86°F (30°C). Even the driest months (January–February) see 2–2.5 inches of rain, which is why the Quepos area maintains its lush, jungle character year-round unlike the browner dry landscapes of Guanacaste in dry season.
Manuel Antonio National Park by Season
Manuel Antonio National Park is worth visiting in any season, but the experience differs significantly between dry and rainy season. The park is one of the top wildlife viewing locations in all of Central America, and its compact size (6.8 sq miles/17.5 sq km) packs extraordinary biodiversity.
Dry season (December–April): Trails are drier and more navigable. Wildlife is easy to spot as animals concentrate around water sources. The beaches within the park (Playa Manuel Antonio and Playa Espadilla Sur) are calmer and cleaner. Snorkeling around the rocky headlands is at its best. The park is busiest on dry season weekends and during spring break—arrive by 7 AM to beat crowds and see the most wildlife before the heat of the day.
Rainy season (May–November): Trails are muddier but still navigable. Wildlife is extraordinarily active—troops of squirrel monkeys, capuchins, and howler monkeys are vocal and visible. Sloths seem to be in every third tree. The forest is vibrantly green and photogenic. The beaches are less crowded. The park closes on Tuesdays year-round. Arriving early is still the best strategy—mornings are often clear even in the rainy season.
Wildlife You'll See
Manuel Antonio reliably delivers sightings of: three-toed sloths (in cecropia trees near the park entrance), two-toed sloths (also present), white-faced capuchin monkeys (bold and numerous), mantled howler monkeys (heard more than seen—their roar carries for miles), Central American squirrel monkeys (endangered; Manuel Antonio is one of few places to see them), scarlet macaws, rainbow-billed toucans, and Jesus Christ lizards (basilisks that run on water). Raccoons, agoutis, coatis, and numerous bird species complete the cast.
Best Time to Visit Quepos
January through April offers the best combination of weather and wildlife for most visitors. The dry season brings reliable sunshine to Manuel Antonio's beaches, clear trails in the national park, and excellent conditions for all activities. February and March are particularly good: very low rainfall, warm temperatures, scarlet macaws nesting, and peak wildlife activity in the park.
However, don't discount the rainy season. May through August offers a wonderful balance of lower prices (30–40% less than peak season), still-manageable rain patterns (sunny mornings, afternoon showers), and spectacularly green and active wildlife in the park. The Quepos fishing fleet operates year-round, and sport fishing is actually particularly good in July–October when offshore billfish are abundant.
The least recommended period for Quepos beach vacations is September and October, when rainfall reaches its peak at 20–25 inches per month. Even these months have sunny days, and the region's waterfalls are spectacular, but the probability of rain interrupting beach plans is at its highest.
Fishing in Quepos
Quepos is known as one of the best sport fishing ports on the Pacific coast of the Americas. The town has a thriving sport fishing fleet targeting Pacific sailfish, marlin, roosterfish, dorado (mahi-mahi), wahoo, and yellowfin tuna. Fishing is productive year-round, but the peak season varies: sailfish and marlin are most abundant November through April; dorado peaks May through September; roosterfish are present year-round near inshore structure. Quepos Marina is the hub for charter fishing operations.
What to Expect at Quepos Beaches
The main beach at Quepos town (Playa Boca Vieja) is used primarily by local fishing and water sports operators rather than for swimming—this working harbor area is not a typical tourist beach. The best beaches near Quepos are within Manuel Antonio National Park (Playa Manuel Antonio and Playa Espadilla Sur) or just outside the park (Playa Espadilla Norte, a popular surf and bodyboard beach).
Playa Manuel Antonio inside the park is one of the most consistently calm and swimmable beaches on the Central Pacific coast. The sheltered bay with clear tropical water is excellent for swimming, bodyboarding, and snorkeling near the rocky points. During peak dry season (January–March), the beach can become crowded by 10 AM—arrive early for a full beach day with shade trees and fewer people.
Ocean Temperature and Conditions
Pacific Ocean water temperatures near Quepos average 80–84°F (27–29°C) year-round. The warmest water typically occurs during the rainy season (September–October), and the coolest during the dry season peak when upwelling events can temporarily reduce surface temperatures to 75–78°F (24–26°C). Even at the cooler end of this range, the water is warm enough for comfortable swimming and snorkeling without a wetsuit. Snorkeling visibility is best in the dry season at 15–30 feet (5–9 meters).
