- Weather: Warm days with afternoon rain. Sep–Oct bring the heaviest showers on the Pacific; the Caribbean often sees more sun.

Shoulder Seasons (May–June, September–November)
Shoulder months offer a balance between sunshine and value. Early green season (May–June) is a sweet spot: bright mornings, blooming landscapes, greener forests, and lower prices than the peak months. Sep–Nov can be wetter on the Pacific, but prices remain favorable for those flexible with plans.
El Niño & La Niña Effects
Large-scale climate patterns sometimes nudge Costa Rica’s weather.
- El Niño: Tends to bring hotter, drier conditions, especially on the Pacific side.
- La Niña: Tends to bring wetter conditions, with stronger rains in some regions.
You don’t need to plan your entire trip around these cycles, but being aware of them helps set expectations, especially if you’re targeting off-road adventures or remote lodges.
Regional Weather at a Glance
- Pacific Coast (Guanacaste, Nicoya, Central & South Pacific): Pronounced dry season from Dec–Apr; wettest around Sep–Oct. Hottest, sunniest beaches in dry season—think Playa Flamingo, Tamarindo, Playas del Coco.
- Caribbean Coast (Puerto Viejo, Cahuita, Tortuguero): Wetter overall but with frequent Sep–Oct sunshine. Great for turtle nesting and mellow surf windows.
- Central Valley & Highlands (San José, Alajuela, Heredia, Monteverde): Mild temperatures year-round thanks to elevation; expect afternoon showers in green season.
