Santa Teresa (Malpais) sää — toukokuu

Monteverde-forum threads asking if the rainy season is tolerable get a consistent yes, posters describing rain as far less disruptive inside the cloud forest reserve itself, where the dense canopy offers real cover from all but the heaviest downpours. Evenings are called genuinely cool, into the 50s Fahrenheit, and posters are consistent that damp plus cool at elevation feels noticeably colder than the number alone suggests, a fleece under a proper rain shell the standard combination. Big downpours are real and worth planning for, ponchos recommended over umbrellas given the wind that often comes with heavier systems. Regulars call May a genuine transition month - greener, mistier and quieter than the sunnier high-season peak, with forest wildlife activity several posters call noticeably better once the rains properly return. The record: 25.1C days feeling like a punishing 28C, 18.4C nights, an extraordinarily high 251mm across over 23 days and 83 percent humidity.

Santa Teresa forum threads describe August as genuinely rainy country-wide, with the typical pattern being sunny mornings, a real chance of afternoon rain, and possibly wet overnight stretches too - posters called mid-August 'nice and wet' rather than a washout. The consistent advice was to front-load activities for the morning and treat the area as a place to slow down and relax in the afternoons. Multiple threads flagged that the heaviest rainy season here doesn't really start until the very end of August into September/October, when some restaurants and hotels close for the slow season, meaning earlier August still runs noticeably better than what follows it.

Forum posters place February and March inside Guanacaste/Nicoya's dry season - genuinely dry and dusty by Costa Rican standards, a sharp contrast to the wetter months later in the year. The typical pattern posters describe even in the dry season: sun and partly cloudy skies dominate, with any rain that does show up more likely arriving late afternoon or at night rather than disrupting daytime plans - the standard advice is to schedule surfing, beach time and outdoor activities for the morning and early afternoon regardless of month. Posters consistently name this Pacific Nicoya Peninsula stretch (Santa Teresa included) as one of the more reliably dry corners of Costa Rica during the dry season months.
