Best Time to Visit
The best time to visit French Guiana depends on what you're looking to see and do. The dry season, which runs from July to November, is the best time to visit if you're looking to explore the rainforest and see the wildlife. The weather is less humid and the visibility is better, making it easier to spot the animals and birds.
The rainy season, which runs from December to June, is the best time to visit if you're looking to see the waterfalls and enjoy the lush green landscape. This is also the best time to visit the beaches, as the water is warmer and the sea is calmer.
Overall, French Guiana can be visited all year round, but it is important to keep in mind that the weather can be unpredictable and can change quickly, so visitors should be prepared for all eventualities.
