Costa Rica in August

August typically feels very humid with a mix of sunshine and daily cloud build-up that often collapses into heavy late-afternoon storms; road conditions can deteriorate quickly on rural routes.

Bring quick-drying clothing, insect repellent, and flexible plans - mornings are the most reliable time for outdoor adventures.

Bring waterproof cases for cameras and footwear with good grip for muddy trails.
