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
Costa Rica January — aerial view of the Pacific coastline in Guanacaste with turquoise water and green hills

January

#12 of 12 months

Strong option

Pacific coast at its absolute driest — Guanacaste beaches are perfect, but expect peak crowds and prices.

  • ↑Guanacaste and the Pacific North are in full dry season: Tamarindo, Nosara, and Playa Conchal deliver reliably sunny days, calm seas, and ideal beach conditions
  • ↑Best month for spotting dry-forest wildlife in Guanacaste — without leaf cover, animals including howler monkeys, iguanas, and coatis are far easier to see

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

January trade-offs

  • ↓Peak prices across the board — accommodation, flights, tours, and rental cars are at annual highs; January is the most expensive month after Christmas week
  • ↓Most popular national parks (Manuel Antonio, Arenal, Corcovado) are at their busiest; advance booking essential for accommodation and park entry
  • ↓Caribbean coast (Puerto Viejo, Tortuguero) is in its rainy season — if the Caribbean is your goal, this is not the right month
