Weather uncertainties 2023 to go to Cayenne ?

Stormy risks under tropics

Risks of tropical rains and showers
In the tropics, these storm or rain pictograms indicate that tropical showers or stormy weather are possible. It is difficult to predict the exact local weather in the tropics. This is especially true by the sea and the beach. Consider that more than 180 mm of rain per month is the limit to enjoy the beach on vacation. So check this data provided for each month on the preferred destinations of this site.

When traveling in the tropics as a seaside, rain is not welcome. If you see this indicator, with possible storms, that does not mean that it will rain all day long. When we observe the local rainfall, it is either really zero or very weak. Meteorologists prefer to be pessimistic. So observe below, the skies photographed during a week announced stormy in Asia. It did not rain once. I invite you to integrate this parameter before going to Cayenne for a good trip to the sun!
