Costa Rica December — Arenal Volcano towering over lush green fields as the Pacific dry season returns to San Carlos

December

#11 of 12 months

Strong option

Dry season returns to the Pacific — Christmas week is the single most crowded and expensive period in Costa Rica.

  • ↑Pacific coast dries out rapidly through December: by mid-month, Guanacaste beaches are back to dry-season reliability, and the timing coincides with the start of peak visitor season
  • ↑Christmas and New Year are festive throughout Costa Rica — San José's Plaza de la Cultura and beach towns like Tamarindo and Manuel Antonio have a genuinely celebratory atmosphere through the holidays
Costa Rica July — golden sunset over the Pacific at Marino Ballena National Park, Uvita — home of the humpback whale watching season

July

#1 of 12 months

Best match

Humpback whales arrive off the Pacific coast and sea turtles begin nesting at Tortuguero.

  • ↑Humpback whale watching season opens off the Pacific south coast (Marino Ballena National Park, Drake Bay) — the July–October migration of humpbacks from Antarctica is one of the world's great wildlife spectacles, viewable on day boats
  • ↑Green turtle nesting begins at Tortuguero National Park on the Caribbean coast — guided night beach walks to watch turtles lay eggs are among the most extraordinary wildlife experiences in Central America

December trade-offs

  • ↓Christmas week (Dec 23–Jan 2) is the single most expensive and crowded period in Costa Rica's calendar: hotels near beaches and national parks are booked months ahead, prices hit annual peaks
  • ↓Domestic travel surges over the holidays as Costa Ricans join international visitors at the coast; roads to popular beaches are congested and parking at national parks reaches capacity by 7am
  • ↓Early December (before the 20th) is a genuine sweet spot with improving weather and pre-peak pricing — arriving mid-December or later requires exceptional advance planning and budget

July trade-offs

  • ↓Pacific rainfall continues at 211mm: the morning-clear, afternoon-wet pattern holds, and planning activities for early morning is essential
  • ↓Tortuguero turtle tours require advance booking through licensed operators — only a limited number of visitors allowed on the beach each night; reserve weeks ahead
  • ↓Still low season pricing which means infrastructure is quieter; some upscale lodges and tour operators work at reduced capacity
