How to read this

These are NOAA’s official 1991–2020 climate normals for one weather station, not a model of the whole park. The station is the one with complete temperature and precipitation normals nearest to a visitor center. Highs and lows are daily averages for the month; “wet days” are days with at least 0.01 inch of precipitation. Mountain parks can be 10–20 °F cooler at their high points than at the station, and the NPS weather page for Virgin Islands is the place for current conditions and seasonal closures.

Sunrise and sunset are computed with the NOAA solar equations for the park’s coordinates and shown in America/St Thomas time for the 15th of each month of 2027; they are accurate to about a minute.
