Costa Rica Weather in January

January is right in the middle of Costa Rica’s dry season, so it’s one of the best times to visit if you’re after sunshine and clear skies. Most of the country sees warm days, low humidity, and barely any rain—especially on the Pacific side. That said, even though it’s the dry season, you might still get the occasional shower depending on where you are, especially in more remote or tropical areas. Here's our guide to the weather in Costa Rica in January.

What is the weather like in Costa Rica in January?

The weather in Costa Rica in January is pretty ideal. It’s part of the dry season (which runs from November through April), so you can expect plenty of sunshine, clear skies, and minimal rain. This makes it a great time for outdoor activities like hiking, beach days, or wildlife watching. Rain is rare, usually just around 0.5-1 inch (12-25mm), compared to the much heavier rainfall in the wet season. The Pacific coast stays the driest, though the Caribbean might get a quick shower every now and then.

Average daily temperatures in January

In terms of temperatures, it’s generally warm and comfortable, but it does vary depending on where you are. You’ll get sunny days with low humidity, and nights are typically warm, especially at lower elevations. If you’re heading up into the mountains like Monteverde, expect it to cool down a bit, so it’s worth bringing a light jacket. 

The ocean along the Pacific coast sits around 84°F (29°C), which is fantastic for swimming or other water activities. With about 11.5 hours of daylight, you’ll have plenty of time to enjoy your day. For more tips, see our guide to how to plan a trip to Costa Rica.

Guanacaste (Northern Pacific)

This is a great spot for beach weather in January. Temperatures range from 75-90°F (24-32°C), with almost no rain. Beaches like Tamarindo, Flamingo, and the Papagayo Peninsula get plenty of sunshine and a nice breeze. 

The dry season turns the tropical dry forests a golden color, which gives the landscape a different feel compared to the usual green.  It’s also a good time for wildlife viewing, as animals tend to gather around the few water sources available.

Central Pacific (Manuel Antonio/Jacó)

The weather here is warm, with temperatures between 75-88°F (24-31°C) and little rain. Manuel Antonio National Park is at its best, with dry trails that make it easier to spot sloths, monkeys, and tropical birds. The calm ocean is perfect for swimming and snorkeling. The towns of Jacó and Manuel Antonio have a lively atmosphere, with all the tours and services up and running.  

Central Highlands (San José/Monteverde)

Temperatures in the Central Highlands are a bit cooler, around 65-80°F (18-27°C). Nights can get chilly, so bring a light sweater. The cloud forests in Monteverde and the areas around San José are mostly clear in the mornings, with some clouds rolling in later in the day. Rain is rare during this time, and the dry conditions make it easier to explore the trails, hanging bridges, and ziplines without the usual mist.

Is January a good time to visit Costa Rica?

Yes, January is actually one of the best months to visit Costa Rica. It’s right in the middle of the dry season, so you can expect plenty of sunshine and clear skies across most of the country. The weather is great for outdoor activities, whether you’re planning on hiking through national parks, spotting wildlife, or relaxing on the beach. With minimal rainfall, you’ll have great conditions for swimming, surfing, and snorkeling—especially along the Pacific coast. This month can also be good for seniors; see our guide to Costa Rica senior tours.

What about the crowd & cost?

January is definitely high season in Costa Rica, especially in the first half of the month when vacation travelers are still around.  Manuel Antonio, Tamarindo, and Arenal tend to be pretty busy, with beaches and national parks drawing large crowds. This popularity also brings higher prices, so expect accommodations to cost quite a bit more than other months. To get the best options, it’s a good idea to book tours and lodging in advance.

If you want similar weather but fewer tourists, consider visiting in the latter half of February or early March. The dry conditions will still be in place, but the crowds from the vacations will have started to thin out. Alternatively, April offers dry weather too, but the high season is winding down, so you’ll see fewer tourists and potentially lower prices.

Where to go in Costa Rica in January

Dry season is in full swing—ideal for beach days, wildlife, and exploring national parks.  

Poás Volcano National Park

Poás is easier to see in January since there’s usually less cloud cover. The main trail is short and paved—just about a kilometer—so it’s not a tough walk. At the viewpoint, you’ll see a wide crater with a bright, mineral-rich lake and steam vents. It’s worth going early in the morning for the clearest views, since clouds tend to build up as the day goes on. Around the volcano, there are a few other trails through the cloud forest where you can spot birds and check out some of the high-altitude plants that grow in the area.

Monteverde Cloud Forest Reserve

Monteverde usually sees less rain in January, which makes the trails easier to hike. It’s also when Resplendent Quetzals start showing up more often—they’re easier to spot during mating season, especially in the early mornings. The trails here run through thick cloud forest full of moss, orchids, and tall trees. If you’re up for more activity, this is a good time to try the hanging bridges or a canopy tour. Night walks are also worth doing—there’s a good chance of seeing animals like kinkajous, snakes, and insects that only come out after dark. See more about Costa Rica wildlife

Cahuita National Park

Cahuita is on the Caribbean side, and January usually brings calm water and good visibility, so snorkeling is at its best. The reef is close to shore, and there’s a coastal trail that takes you through forest and along the beach. You’ll probably see monkeys, sloths, and maybe even some brightly colored frogs along the way. The whole area has a slower pace compared to the Pacific side, and there’s a strong Afro-Caribbean influence in the local food and music.

What to do in Costa Rica in January

The dry season means sunny days and clear skies, which is ideal for everything from wildlife watching to adventure sports. The animals tend to gather around water sources, so it’s a good time to see them up close. For those into outdoor adventures like zipper lining or surfing, the weather stays reliable, and you won’t have to worry about interruptions from rain.

Visit local festivals

If you’re in Costa Rica in January, you’ll find a number of local festivals, especially in smaller towns like Santa Cruz in Guanacaste. These traditional fiestas are a great way to experience local culture, with bullfights (where the bull isn’t harmed), horse parades (topes), live music, dancing, and food stalls with local dishes. It’s a nice chance to dive into Costa Rican traditions, especially the cowboy culture, and mingle with locals in a more relaxed setting, away from the big tourist spots. This is a great thing to do in Costa Rica with kids.

Sea turtle nesting

January is a prime time for witnessing the mass nesting of olive ridley sea turtles at beaches like Ostional on the Nicoya Peninsula. If you’re lucky, you’ll see hundreds of turtles emerge from the ocean to lay their eggs under the moonlight. It’s an amazing wildlife experience that you won’t forget. There are guided tours that make sure you watch the turtles without disturbing them, which is key to protecting these endangered creatures. Some beaches even start seeing leatherback turtles begin their nesting season in January. See our favorite Costa Rica rainforest tour.

Explore San José

While many travelers head straight for the beaches and rainforests, Costa Rica’s capital, San José, is worth checking out in January, especially with the cooler weather. The city comes alive with outdoor events like art exhibitions and concerts in parks. You can also visit museums like the Pre-Columbian Gold Museum, the Jade Museum, or the National Museum to learn about the country’s history and indigenous cultures. 

San José’s food scene is another highlight, with everything from bustling local markets to modern restaurants focused on fresh, local ingredients. The comfortable temperatures and the mail-vacation energy in the air make January a great time to explore the city.

Planning your trip to Costa Rica in January

Some Costa Rica travel tips to help you plan your trip:

What to pack

You’ll mostly live in light, breathable clothes—shorts, t-shirts, sundresses, whatever feels good in the heat. Toss in a light jacket or sweatshirt for the mountains, where nights can surprise you with a chill. If you’re planning to hike, proper shoes make a big difference. A swimsuit is essential—between beaches, hot springs, and hotel pools, you’ll use it more than once. Sun protection is non-negotiable: high-SPF sunscreen, sunglasses, and a decent hat with a brim. 

Planning your itinerary

If you're getting ready to visit Costa Rica in January, starting with a sample itinerary can be a smart way to get organized. It gives you a solid idea of what your trip could look like. Here are a few that might work for you:

  • Costa Rica itinerary 5 days: Spend a day or two in San José exploring the city, then head to La Fortuna for rainforest trails and waterfalls. You can check out Arenal Volcano and its hiking paths, plus enjoy the hot springs. End your trip in Monteverde, where you’ll find misty cloud forests and hanging bridges, and make time for a coffee farm tour back in San José.
  • Costa Rica itinerary 7 days: Start in San José, then head to Manuel Antonio to enjoy its beaches and rainforests for a few days. Next, zipper-line through the Monteverde Cloud Forest and check out the hanging bridges. Finish your trip in La Fortuna with a visit to Arenal Volcano for trails, waterfalls, and some time to relax in hot springs.
  • Costa Rica itinerary 10 days: Begin in San José, then explore Tortuguero’s wildlife-filled canals before making your way to La Fortuna and Arenal Volcano. Spend some time at Manuel Antonio National Park, known for its beautiful beaches and diverse wildlife. Finally, wrap up at Jaco Beach for some surfing and stunning sunsets.
  • Costa Rica itinerary 14 days: This one covers a lot of ground. Start in San José, then explore Tortuguero’s canals, Puerto Viejo’s Caribbean culture, and Cahuita’s coral reefs. From there, visit La Fortuna and Arenal Volcano, followed by Monteverde’s cloud forests, and finish in Manuel Antonio with its beaches and wildlife.

When to book

January is one of the busiest times to visit Costa Rica. The weather’s great, and a lot of people come to escape winter, especially around New Year’s. Places like the Central Pacific and Guanacaste get crowded fast. If you're heading to the beach, try to book your hotel three or four months ahead. Flights fill early too, so it's worth locking those in as soon as you can. Tours—like zipper-lining, visiting Arenal, or heading into Manuel Antonio National Park—usually need to be reserved a few weeks in advance.

Emergency weather information

January usually means good weather, but if you’re near the Pacific coast, keep an eye out for Papagayo winds. These gusts can stir up strong rip currents, especially around beaches in the north. Before swimming, check signs posted at the beach or ask someone local—hotel staff are usually in the know. It’s also smart to carry a whistle when you’re in the water, just in case.

If you’re heading into the mountains, quick electrical storms can roll in. Know where the closest shelters are along your route. The National Meteorological Institute (IMN) has a handy app for real-time updates. 911 works countrywide, and it’s worth keeping waterproof copies of your ID and important docs in case you need to leave in a hurry.
