อากาศSanta Teresa (Malpais) เดือนพฤศจิกายน

November here is the rainy season's last real month, and regulars describe a specific daily shape to it: clear days with thunderstorms arriving reliably around six each evening, rather than rain spread evenly through the day. Our row carries the season's tail at 280.2mm across 25.5 days, still substantial, at 87.6 percent humidity - air reads 29.1C but as a real 35C, over 24.6C nights. The board's honest caveat is that Costa Rica has a dozen microclimates, so rain elsewhere on a given day says little about here. A four-wheel-drive is worth having for the last of the season's soft roads. The foliage is at its greenest now, before the dry months bleach it back. The sea is 28.7C. The record: 9.1 hours of sun, a 10.8 kph wind and one of this project's cleanest air readings at AQI 22.

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.
