The best time to go to Ostuacán is during the dry season, which runs from November to April.
During these months, you'll experience pleasant, warm weather with minimal rainfall, making it ideal for exploring the region's natural beauty and outdoor activities. The days are typically sunny, with average temperatures in the mid-20s Celsius, great for hiking, visiting archaeological sites, and enjoying the local culture without the humidity and heavy downpours of the rainy season.
Travellers looking for a comfortable and active holiday will find this period particularly appealing. The clear skies and accessible trails make it easy to plan excursions to nearby waterfalls or explore the lush landscapes. It's also a good time for those interested in local festivals, as many are scheduled during the drier months.
While the wet season (May to October) brings lush greenery, it also comes with higher humidity and frequent heavy rains, which can sometimes disrupt travel plans and make outdoor activities less enjoyable.
