Remember:
The climate in French Guyana in march ranges from tolerable to bad depending on the region and city.
March is not the best month to visit French Guiana. The weather in Saint-Laurent-du-Maroni, Sinnamary, Kourou, Roura, Awala-Yalimapo and Cayenne is just ok. The sun is not there all the time and you risk you to be soaked by rain frequently. Nevertheless, if you don't plan a beach and relaxation travel but rather discovery of heritage, this climate may be enough. In addition, there are definitely fewer tourists during this period.
It's much worse in Maripasoula and surrounding area where the climate is very bad. It is really not advisable to go to this area in march.
