San Vito sits at around 1,000 metres above sea level, which gives it a markedly cooler and fresher climate than the coastal lowlands. Temperatures are pleasant year-round — rarely hot, rarely cold — but the difference between wet and dry seasons is significant.
Dry season (December to April) is the most comfortable time to visit. Days are clear, trails are passable, and the journey in by road is straightforward. This is the best time for birding at the Wilson Gardens, when visibility is good and the forest is active. It also coincides with coffee harvest season (November to February), when the farms are busy and the smell of processing beans fills the air.
Wet season (May to November) brings heavy afternoon rains, sometimes all day. The roads can become difficult, particularly the unpaved approaches to Parque Internacional La Amistad. The Wilson Gardens, however, are at their most lush — palms dripping, every shade of green intensified, and the plant collection in full extravagant growth. Serious botanists often prefer this period for exactly this reason. Birding continues to be excellent; many migratory species pass through in October and November.
There are no major festivals or events that would drive travel timing. San Vito is a working agricultural town, and the rhythms that matter are agricultural rather than touristic.
