Costa Rica March — Arenal Volcano rising through cloud above lush green forest in San Carlos

March

#9 of 12 months

Strong option

Hot, dry Pacific coast with spring break arrivals — excellent conditions but prices stay high.

  • ↑Pacific coast conditions remain excellent through March: minimal rainfall, warm temperatures, and calm enough seas for snorkelling at Caño Island and Isla del Caño
  • ↑Spring break (US and European) brings energy to beach towns; Tamarindo and Santa Teresa have a lively atmosphere without being overwhelmed
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

March trade-offs

  • ↓Prices remain near-peak through mid-March; spring break weeks push accommodation in beach towns to high-season levels
  • ↓Temperatures hit their hottest of the dry season — 27°C with growing humidity as the transition approaches; beach afternoons can feel intense
  • ↓End of March signals the first rains arriving on the Pacific; some years the green season arrives early and April showers begin in the final days of March

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
