Het weer in Tamarindo, Costa Rica in februari

Forum posters describe late January into February around Nosara as typically bringing daytime highs in the low 30sC with evenings around 27-28C, squarely within Guanacaste's dry season and generally favorable conditions. Posters consistently rate the water at Nosara's main beach, Playa Guiones, as warm and clear this time of year, while flagging that wave size there can get large enough to require some caution for less experienced swimmers or surfers. Posters generally rate February as one of the more reliably dry, pleasant months to visit Nosara, with the dry-season heat as the main thing to plan around rather than any real rain risk.

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.
