In October, the afternoon sky over Uvita turns the color of slate, the first heavy drops hit the tin roofs, and the rainforest behind the town seems to breathe out. Out past the surf, a humpback may still slap its tail on the water while the whale’s-tail sandbar at Marino Ballena slowly appears at low tide. This is the green, quiet, deeply tropical side of the southern Pacific coast, for travelers who like their beaches uncrowded and their jungle dripping.
What is the weather like in Uvita in October?
In Uvita, October brings heat, heavy humidity, and plenty of rain, falling on nearly every day of the month, while the ocean stays as warm as bathwater.
| Month | Average high (°F) | Average low (°F) | Rain days | Sea (°F) |
|---|---|---|---|---|
| September | 80.8 | 72.9 | 29.6 | 85.8 |
| October | 80.0 | 72.8 | 30.7 | 85.1 |
| November | 79.9 | 72.3 | 29.2 | 83.0 |
Mornings are the gift of the month. Warm, damp air and soft light greet you, and the sky usually stays clear long enough for a beach walk, bird-watching, or a boat trip before clouds roll in. Plan anything outdoors for the first half of the day and treat the afternoon as flexible.
Afternoon and evening are when the rain usually shows up, frequently in the form of a heavy downpour lasting hours and at times stretching into the night. Some days bring a few steady showers rather than one big storm, and a good number of days in the month deliver an inch or more. Trails turn muddy, rivers rise and the road to waterfalls can be slick, so keep the schedule loose.
Nights stay warm enough for short sleeves, though a light rain jacket is the layer you will actually use. The temperature barely moves between day and night, so the real variable is the sky. Between showers the forest is intensely green and the air smells of wet earth and flowers.
Can you swim in Uvita in October?
Sure, you can linger in that warm water for as long as you want, but what’s happening at the beach counts for more than how hot it is.
The Pacific off Uvita is usually soft and inviting in the morning, with the surf often picking up later in the day and after heavy rain. The long beach at Marino Ballena National Park frames the whale’s-tail sandbar at low tide. Rain upstream can send brown water and debris into the sea, so a day after a big storm is not the day for snorkeling.
Rip currents, which pose a serious threat, claim the lives of several U.S. tourists here every year. Since lifeguards are rare on these shores and danger notices are often missing, check with locals about today’s water, swim near other bathers, and avoid the sea when surf runs high.
Families with small children and nervous swimmers do best with a calm morning and a spot close to shore. Bring a rash guard, a dry bag and a reusable water bottle.
What to do in Uvita in October
The headline of October is the tail end of the second humpback whale season. Twice a year humpbacks come to this coast, about December through April and again about July through October, giving it one of the globe’s longest stretches for whale watching. October is the closing stretch of the second window, so sightings are a chance rather than a promise, and a morning boat trip is the best way to improve those odds.
The month has no big local festival in town. Elsewhere in the country, October 12 is the Day of the Cultures, and Limon holds its Carnival around that date, with parades, music and Afro-Caribbean food. Dates can shift from year to year, and Limon is on the other coast, so it is a trip for those who want to cross the country rather than a side trip from Uvita.
Marino Ballena National Park and the whale’s tail
Uvita draws most of its visitors because of the park. A whale’s tail shaped sandbar reaches out from the beach, and at low tide you can walk its length with water on both sides. Go early, when the light is gentle and the sky is most likely to be clear, and leave before the afternoon clouds close in.
The park sits right at the edge of town, so getting there takes a short ride or walk from most hotels. Almost anyone will find it a good fit, from photographers to families, and the ideal time depends on the tide, so check with your hotel about when low tide arrives that day.
Whale-watching and boat trips
Boat trips search for humpbacks off the coast of Uvita. Mothers with calves are the classic sight in this region, and dolphins and seabirds often turn up on the same trip. Mornings are better than afternoons in October, because the squalls build later in the day.
Expect to see the animals only if luck is with you, and expect to get a little wet. Bring a rain jacket, sunscreen and a hat, and take motion-sickness tablets if you are prone to it. October is the closing stretch of the second humpback season, so sightings are a chance rather than a promise.
Rainforest, waterfalls and birds
Behind the coast, the hills rise into dense, wet forest, and October is when it looks its most lush. Most visitors spot creatures like monkeys, toucans and, if they are lucky, sloths on guided walks. The rain keeps the creeks running and the canopy loud with frogs and insects at dusk.
Head out early and put on footwear that grips, since the paths and stones turn slick. Head out early and put on footwear that grips, since the paths and stones turn slick. In the heat of the day, a cold fruit juice at a roadside soda is a fine reward.
In town, the casado is the center of the table, a plate of rice, beans, plantain, salad and your choice of fish, chicken or beef, along with whole fresh fish grilled over coals down by the coast. Gallo pinto, the rice-and-bean mix, shows up at breakfast with eggs and fresh fruit. A bowl of ceviche or a coconut water on a wet afternoon is the right kind of comfort.
The mood in the streets is slow and unhurried. Many visitors are off-season travelers who came for nature rather than nightlife, so evenings are quiet, with dinner, a drink and an early night before a dawn start. Rainy afternoons suit a hammock, a book, a long lunch or a visit to a local chocolate or coffee farm.
A two-day itinerary for Uvita in October
Day 1 belongs to the sea. Start at first light, since the day is about twelve hours long and the best weather is early. Have breakfast of gallo pinto and fruit, then head out on a morning whale-watching boat while the water is calm. Back on land, have a late lunch of grilled fish at a seaside restaurant and rest through the hottest part of the day.
In the afternoon, as the clouds arrive, drive or walk to the edge of Marino Ballena and walk the sandbar if the tide is out. If the rain starts, shelter under a beach restaurant roof and watch the squall roll across the water. Dinner is simple, at a casual place in town, with an early night.
Day 2 goes inland. Set out early for a guided rainforest walk in the foothills, looking for birds, monkeys and waterfalls while the morning light is still clear. Stop for a juice and a casado at a roadside soda afterward.
If the afternoon turns wet, make it a slow one: a chocolate or coffee farm tour, a long lunch under a tin roof, or a book in a hammock. When the rain eases, take a short walk along the shore to catch the last light, then finish with dinner at a family restaurant in town.
Is Uvita busy in October?
No, October is one of the quieter months here, with a relaxed pace on the beaches and in town.
The rain keeps the crowds thin. Those who come are mostly nature lovers, whale-watchers, surfers and long-stay travelers, so rooms are usually easy to find and restaurants rarely fill.
Booking early matters most for the holiday weeks from December onward, when rain comes in short showers between sunny stretches.
Because it is so quiet, a few small spots cut back their hours or shut down for a rest during the year’s wettest stretch. Ask your hotel which restaurants and tour operators are running that week, and keep a second plan for any outing that depends on the weather.
What to pack for Uvita in October
Bring quick-drying clothing plus gear that shields you from sun and mud, since October means warmth, damp air and rain every day.
- A lightweight rain jacket, because afternoon downpours are the rule.
- Pack fast-drying shirts and shorts, because in this humidity everything dries quickly.
- Sandals and shoes with good grip for wet trails and rocks.
- Sunscreen and a hat for the clear mornings on the water.
- A dry bag for phone, camera and passport on boat trips.
- Insect repellent for dawn and dusk in the forest.
Good to know before you go
The U.S. State Department rates Costa Rica Level 2, ‘Exercise increased caution,’ due to crime; it says petty crime is common throughout Costa Rica and that violent crime also affects tourists, including armed robbery, homicide and sexual assault.
October lands in the Atlantic hurricane season, and even though Uvita is on the Pacific side, days of hard rain can still hit roads and plans. Allow slack in your schedule, keep flights flexible if you can, and drive in daylight when roads are wet. Book a whale-watching boat and your first night’s room before everything else.
Uvita in October vs September and November
Moving a month earlier brings you to September, which is almost identical in temperature, with a slightly warmer sea and the whales still in the middle of their second visit. It is the more reliable month for sightings, and the rain is just as persistent.
Moving a month later puts you in November, when the sea cools a little, the whale window has closed and any dry stretch is still weeks away, with rain arriving as short showers and the odd wetter spell. Some businesses start to reopen and prepare for the high season, and the mood begins to shift from empty to expectant.
If whales matter most, choose September or early October. If you want the quietest beaches and do not mind a gray afternoon, October is fine. If you prefer to wait for the drier months and the busier calendar, December onward is a better fit.
Is October a good time to visit Uvita?
Yes, for travelers who love green forest, warm water and empty beaches and who accept that the afternoons belong to the rain.
It will suit whale-watchers, birders, photographers and anyone happy to plan around the weather, with mornings for the outdoors and afternoons for a long lunch. Travelers who crave dependable sunshine, a buzzing night scene, or whole days with nothing planned on the sand will find it a poor match.
On arrival, settle in, ask your hotel when low tide falls and book your boat trip for the first clear morning. Then enjoy what only this month gives: the last humpbacks of the season off a wet, quiet, intensely green coast.
