French Guiana
This is a matter of language use in non-French speaking countries. It is probably that way to avoid confusion with the other Guianas (there were five separate colonies from different European countries). To the French, French Guiana is simply La Guyane.
Because the weather is more consistent in French Guiana.
The Guianas is a term that is used for the countries of Suriname, Guyana and French Guiana.Specifically, Suriname is the former Dutch Guiana, from its colonial years under the European Kingdom of the Netherlands. Guyana is the former British Guiana, from its colonial years under the British. French Guiana alone is not yet independent since it retains its status as overseas department of France.

Along with Suriname (Dutch Guiana), they are on the Caribbean (NE) coast of South America.Guyana is east of Venezuela, followed by Suriname and French Guiana, with Brazil to their south and east. They are the remaining three of five Guiana colonies established by the European countries Spain, Portugal, Britain, France, and the Netherlands.(French Guiana is not a country; it remains part of France)
The three countries are: Guyana (ex British Guiana) Suriname ( Ex Dutch Guiana) and French Guiana (not independent).
