Været i Tamarindo i april

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.

Tamarindo's forum consistently rates July as one of the better rainy-season months - genuinely the driest stretch of the wet season here, with sunny mornings, clouding over by early afternoon, and a shower or thunderstorm that clears out again rather than lingering. Locals reportedly call this the 'little summer of San Juan,' a real break within the rainy season that feels more like a dry-season week. Daytime temperatures stay in the high 80s F, and forum regulars were clear this counts as a genuinely good month to visit, not a compromise pick.

Forum posters describe January as dry and beautiful, squarely inside Guanacaste's dry season - daytime highs commonly in the low 30sC with bright sun essentially every day, evenings cooling to a comfortable high-20sC. The landscape stays green early in the dry season, though posters note the strong 'December winds' (part of the broader Papagayo/Guanacaste wind pattern) can already be drying things out fast. Beaches generally aren't too windy through most of January, though the very start of the month - the wet-to-dry season transition - can see a stronger, gustier stretch. Overall, posters consistently rate January among the most reliable months here for classic sunny beach weather.
