When Is the Best Time To Visit French Guiana?
The answer to the question of what is the best month to visit French Guiana depends on what you are interested in doing during your stay. Here you can see an overview of each month and its typical weather conditions.
Tourist Season in French Guiana
The best time to visit French Guiana includes the months of the dry season from August to December. It's warm and sunny, and the occasional fleeting rains don't hamper your visit. This is the ideal time for beachcombing, sightseeing and trekking.
When organizing a trip during the rainy season, which lasts from January to July, one must take into account the difficulties caused by increased rainfall. They can cause traffic problems; many roads and trails are impassable then, and local flooding restricts tourists' access to some areas. Difficulties may also affect those relaxing on beaches and enjoying the sea.
