Where should you go in French Guyana in may when it comes to the weather?
Remember:
The climate in French Guyana in may ranges from tolerable to very bad depending on the region and city.
That month is not the best month to visit French Guiana. The weather in Saint-Laurent-du-Maroni and Awala-Yalimapo is OK but just acceptable. The sun is not there all the time and you may be faced the rain regularly. Nevertheless, if you don't plan a pool & relaxation travel in French Guiana but rather sightseeing or hiking, this climate may be enough. In addition, there are definitely fewer tourists during this period.
But it gets worse: in Maripasoula, Sinnamary, Kourou, Roura and Cayenne and surrounding areas where the climate is very bad. We really do not recommend you to visit these areas this month.
