The Virgin Islands does not have a rainy season, however there are month to month differences. The rainiest months in the Virgin Islands are November, October, September, August and May. Rainy months does not mean that there is continuous rainfall every day all month long, in fact most daily rainfall reports are below .10 inches. Rain showers are often short and typically occur early in the morning or at night. On a truly rainy day, it will rain off and on for the entire day. All day downpours over numerous days are not common. The driest months are typically February and March.
As mentioned being inundated with rain is not common, but it does happen. In November 2003 the islands experienced record breaking rainfall. St. Thomas experienced 18.39 inches of rain and St. John 18.91 inches. St. Croix’s highest rainfall was in September 1979 with an amazing 21.39 inches. Droughts are a larger problem because the islands are dependent on rain as a source of water.
July to October is our hurricane season. Whilst many people are concerned to charter during this time, there really is a very low chance of a hurricane affecting your vacation.
In the unusual event of a hurricane heading directly for the islands, we may need to call the boat back in. We will help you to find a hotel, at your expense, and you will be refunded, or offered credit, for lost time on the boat during the period we have recalled the boat. Circumstances permitting, once the storm has passed you will be able to continue your charter as normal.
