The average temperature and sunshine deviations between summer and winter are 25%. This small gap means that the temperature at sea does not really vary and that the sea remains warm enough in summer and winter. The air is also hot all year round without great thermal amplitude.

Weather uncertainties 2024 to go to San Juan ?
![Stormy risks under tropics](images/meteo-11d.png)
![Risks of tropical rains and showers](images/meteo-10d.png)
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 San Juan for a good trip to the sun!
