When to go
The best time to visit French Guiana is
from mid-August to mid-November, and in particular, the months of September and October, which are the least rainy and the sunniest, especially on the eastern part of the country. This is also the hottest period, but it is not as humid as the rest of the year, and in any case, what matters most is to avoid the heavy rains.
What to pack
Throughout the year: bring
lightweight clothing of natural fibers, possibly with long sleeves for mosquitoes, a light sweatshirt for the rain showers or the sea breeze, a sun hat, and an umbrella (though it can be useless for heavy showers) or a lightweight and breathable raincoat.
From December to March, you can add a sweatshirt for the evening.
