Is January Right for You?
Weigh the advantages and considerations before booking
- + January is Costa Rica's driest month coast to coast, expect 8, 10 hours of unbroken sun and afternoon showers that rarely outstay twenty minutes, giving you clean skies for zip-lines, surf sessions, and volcano hikes without weather derailing the plan.
- + Wildlife is easier to spot now than at any other time: humpback whales cruise the Pacific, green sea turtles lay eggs on Playa Grande, and shrinking waterholes in the parks draw tapirs, coatis, and deer into tight, camera-ready clusters.
- + You'll feel the real pura vida in January, Christmas stress is behind the Ticos, local families colonise the sand, and the soundtrack switches from tour-group chatter to kids playing soccer between fishing boats.
- + Every corner of the country is open for business: the Pacific beaches glow, Monteverde's clouds lift by mid-morning, and even the normally sodden Caribbean lowlands post their lowest rainfall figures of the year.
- − Peak-season pricing kicks in, lodging costs jump 40, 60 % over September rates, and most beach hotels insist on 3, 4-night minimums during the first half of the month.
- − Manuel Antonio and Arenal fill to their legal limits. Rangers close the gates once the head-count is reached, usually before 8 a.m., so roll up after 7 a.m. and you'll be staring at the ticket line instead of sloths.
- − Rental fleets empty fast, agencies lease every 4WD first, leaving sedans that bottom out on the 15 km of washboard leading into Monteverde's cloud forest.
Best Activities in January
Top things to do during your visit
January overlaps both humpback migrations, California animals heading south and Antarctic whales heading north, creating the planet's only double congregation. Dry-season swells top out at 2 m instead of the usual 4 m Pacific monsters, so even easy-to-queasy passengers stay comfortable. Morning launches from Marino Ballena National Park log 8, 12 whales, with mothers coaching calves through mid-air breaches.
Guanacaste's dry forest is built for January zip-lines, cables stay dry, visibility stretches 30 km across the canopy, and shade temperatures hold under 32 °C. Sparse leaves make it simple to pick out howler monkeys, coatis, and the occasional margay. Early thermals add 15, 20 % to ride length, so the first runs feel like flying.
Clear January skies turn the cloud forest into a planetarium between breaks in the canopy. Night temperatures drop to 18 °C, nudging kinkajous and porcupines downhill, and the dry season knocks leech numbers down 80 % so you can touch mossy trunks without the blood donation. Night walks that start at 5:30 p.m. catch the hand-over between diurnal and nocturnal casts.
January is prime time for 2-m-long leatherbacks. The giants waddle ashore between 8 p.m. and 2 a.m.; the new-moon window around 11 January gives the darkest stage for watching 400-kg mothers excavate nests while surf thunders beside them. Only one in five wet-season visitors gets a show.
The harvest winds down in January, San Ramón and Naranjo smell like caramel as mills process the last red cherries. You pluck fruit alongside three-generation crews, learning to judge ripeness by squeeze, then taste the same beans processed five different ways. Dry slopes mean you keep your footing on 30-degree inclines.
Steady 15-knot trades blow warm enough for swim breaks yet strong enough to heel a boat. Dust in the dry-season sky paints sunset orange into lipstick red. Dolphins sprint the bow wave, and the gulf's protection caps waves at 1 m instead of the 3 m rollers outside the headland.
January Events & Festivals
What's happening during your visit
Palmares throws the country's biggest bash, two weeks of rodeos, concerts, and harmless bull-tagging in the ring. The tope parades 3,000 sabanero-clad riders through town, carnival lights spin overhead, and vendors keep the chicharrón and Imperial beer coming.
Tens of thousands walk the 22-km pilgrimage from Cartago to Basílica de Nuestra Señora de los Ángeles overnight on 14 January, some on bloodied knees, singing hymns beneath the Interamericana's streetlights.
