Guyana has a tropical climate with warm temperatures year-round, averaging 24°C to 31°C (75°F to 88°F).
There are two rainy seasons: May to August and November to January, which can make travel challenging due to flooding.
The best time to visit is between February to April and September to October, when rainfall is minimal, and wildlife viewing is excellent. Birdwatchers and adventure seekers should aim for dry seasons to explore rainforests and waterfalls without disruption.
