The January Reality: Two Coasts, One Country, and Peak-Season Math
The big thing the calendar hides: January is not one climate, it is two. The Pacific northwest around Guanacaste runs bone-dry, with daytime highs commonly near 30-35C and barely a few millimetres of rain all month. The catch nobody warns you about is the Papagayo winds, the offshore gusts that funnel down the Pacific coast from roughly November through April and can spike past 100 kph. Surfers near places like Tamarindo love the resulting offshore lines; anyone planning a small-boat tour or a calm beach day should check forecasts, because the wind can flatten plans without warning.
Meanwhile the Caribbean side around Limon stays genuinely wet in January, often somewhere around 200-300mm, so the postcard sunshine you booked for does not always reach Puerto Viejo or Tortuguero.
What is actually worth timing for January:
- Fiestas Palmares in the town of Palmares (running January 15-26 in 2026), a two-week ranching festival with concerts, horse parades and bull events.
- Northern-hemisphere humpbacks, present but harder to spot than the August-September peak.
The honest cost: this is high season, so expect the priciest rooms of the year and book two to three months out.
