Traveller notes on Tamarindo in July
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.
Other months in Tamarindo
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.
