Rainy Months in Vieques, Puerto Rico

The months of May, October and November are usually the months with the most rain.  Most showers occur early afternoon and they’re short in duration. At times rain pours for a few minutes and the sun shines again.  If you’re visiting during the rainy months or see rain in the forecast, just get up early and head to the beach.  Again, rain typically comes early afternoon. 

When it rains, that’s a great time to visit the museums and shops in town. 

Here’s an old wive’s tale in Puerto Rico:  If you happen to be in Puerto Rico during the FIRST rain in May, get out and get soaked.  Supposedly the first water in May keeps you looking younger. 

Hurricane Season Vieques, Puerto Rico

Official hurricane season in Vieques and Puerto Rico begins on June 10th and ends on November 30th.  Historically, most hurricanes hit the island in the months of August and September. 

If you choose to travel during hurricane season, we highly recommend you purchase trip insurance to protect funds invested in your vacation in case you need to cancel or require emergency care.

One great question to ask the management of the Vieques hotel or vacation rental before booking is whether they have a water reservoir and back up electricity generator and a satellite phone for emergencies.  If you happen to be on the island during a hurricane you will be glad you asked these questions before booking.  

In September 20th, 2017, Vieques, Culebra, and Puerto Rico were hit by Hurricane Maria causing major devastation to the infrastructure, destroying homes and many businesses.  Previous to Hurricane Maria was Hurricane George on September of 1998 which caused around 2 million dollars in damages.
