St. Croix is surrounded by the beautiful Caribbean Sea, which accounts for our consistent year round temperatures. However, with the ocean air comes a lot of humidity, which can make the temperature feel much hotter at times. The relative humidity typically ranges from 58% to 90% over the course of the year, rarely dropping below 49% and reaching as high as 97%. For those of you who may not be familiar with the feel of humidity, under 50% humidity is generally considered comfortable and over 85% is considered very humid. In addition to affecting the feel of temperature, humidity is an indicator of the likelihood of precipitation – the higher the humidity the more likely there will be rainfall.
If you are planning a trip and trying to determine the most comfortable time of the year to be on St. Croix, the air is driest around mid-February, at which time the relative humidity drops below 62% an average of three days out of four. It is most humid around mid-November, exceeding 86% and average of three days out of four.
