Погода: Nosara, май

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.

Regulars are specific it genuinely rains most days here this month, though showers typically stay brief, around 15 minutes, sandwiched between mostly sunny, hot mornings and afternoons and a cooler evening. Our row backs that hot, genuinely wet read, 29.9C reading as a scorching 37C, over 25.2C nights feeling 31C, with a substantial 321.2mm of rain across 27.9 days and humidity at 88 percent. Regulars are consistent long-term residents specifically call this arguably the best time of year on the Pacific coast despite the daily rain, the Guanacaste region itself running meaningfully drier than the rest of Costa Rica, surfing and diving trips still genuinely doable around the showers. The sea sits at a bath-warm 30.2C. The record: 9.2 hours of sun, a 9.7 kph wind and AQI 24.

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.

April is the end of the dry season here and regulars rate it: much drier than May or June, if not quite as dry as February and March. Our row looks like a flat contradiction at 126.2mm across 19.2 precipitation days - until the second half of their answer, which is that the first rains usually begin later in the month. The monthly total is back-loaded, so early April is the dry part and the average is really two different halves added together. Heat is what they actually warn about: hot, hotter, and sand too hot to cross barefoot between the chair and the water. Our 32.8C over 25.8C nights reads as 39C and 30C. The record: humidity 75 percent, 11 hours of sun, a 30C sea and AQI 33.

The rains usually finish in November, so December catches Guanacaste in its best state - dry, but with the foliage still green before the long brown months set in. Our row is a shade wetter than the regulars' 'very little to no rain', at 64.3mm across 10.6 precipitation days, which is the turn rather than the dry season proper. December to March is also when North Americans arrive to escape their winter, so the town fills. For surfers the draw is consistency: Playa Guiones is among the most reliable breaks in the country and a typical season runs knee to head high from November to March, which is why the surf and yoga crowd is here now. The sea is 28.9C. The record: 30.5C reading as 36C, 24.5C nights, 10.3 hours of sun and AQI 24.
