Located amongst the beautiful vicinity of the Caribbean; Sosua experiences very little seasonal variation in both temperature and rainfall.

The tropical climate of Sosua is dominated by the north-east trade winds that blow almost endlessly all year round. Sosua is an exceptionally hot resort with average daytime temperatures nearing 31°C. In this region the sun shines for the majority of the day and due to this, warm and sunny conditions experienced can be expected nearly all year round.

Rainfall and Hurricane Season
Alike any region there is of course a period of time where rainfall is common. This takes place from May to August and although the rain is placid it is enough to keep much of the island green and fertile. A little rain can also occur throughout the months of November and December, yet in these months the climate of Sosua is very Romantic. Similar to many tropical climates it is also common for this region to experience an occasional hurricane. There have been cases with dates over fifty years old that have been quite devastating. The Caribbean hurricane season lasts from June and ends in November. But because the north coast is sheltered by numerous hilled ranges, the harsh storms will commonly bypass Sosua as the hurricane passes directly over the island.
