Santa Teresa (Malpais) 12月 天气

Regulars are specific this area reads as genuinely drier than areas further south along the same coast, where the rainy season doesn't properly end until mid-to-late December, though conditions here have shifted from the old reputation of reliably rain-free North winds - even the tail end of the month can now bring real rain some years. Our row backs that hot, genuinely wet read, 27.6C reading as a scorching 33C, over 24C nights feeling 29C, with a substantial 278.6mm of rain across 28.5 days and humidity at 86 percent. Regulars are consistent Costa Rica's weather is genuinely location-dependent given how many separate weather systems affect the country, no single verdict applying evenly countrywide. The sea sits at a bath-warm 29.1C. The record: 9.9 hours of sun, a 9.7 kph wind and AQI 32.

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.
