Good to know
Good to Know
- Puerto Viejo receives significantly more rainfall than most of Costa Rica, with every month exceeding 160 mm. Pack quality rain gear and water-resistant clothing regardless of season.
- The Caribbean coast experiences rain differently than the Pacific: while the Pacific has defined wet/dry seasons, Caribbean rainfall is spread year-round. When the Pacific is dry (August–October), Puerto Viejo remains relatively drier, making it an alternative to crowded Pacific beach destinations.
- Surfers should note that January through April offer the best waves at Salsa Brava, though this period carries heavier rainfall (especially December–January). Plan indoor backup activities.
- September and October are the most reliably dry months for beach activities, though expect afternoon showers. Tourism is slower during this period, potentially offering better accommodation rates.
- Humidity stays above 85% year-round and peaks at 89–92% in July, making the climate feel consistently warm and tropical. Quick, heavy bursts of rain are typical rather than all-day downpours.
- Daylight hours vary slightly (11.6 hours in January to 12.7 hours in June), but the location does not observe daylight saving time.
