Average Daily Temperatures
St. Croix exists in a perpetual state of Summer, due to it’s proximity to the equator and being surrounded by the Caribbean Sea. Over the course of the average year the temperature typically varies from 73°F to 88°F, and is rarely below 69°F or above 91°F (although it can feel much hotter when the humidity is high). While it does tend to feel like Summer year round, there is still a definite temperature shift that can be felt between locals would consider the“warm season” and the “cool season”.
