Virginia Key is a small island east of downtown Miami, north of Key Biscayne, and south of Miami Beach. The east side faces the Atlantic Ocean and the west side faces Biscayne Bay. It has a tropical monsoon climate, with temperatures strongly moderated by the warm water and two seasons: hot/wet and warm/dry. Coastal areas experience semidiurnal tides with an average seasonal peak in late summer into mid-autumn.
Meteorological and oceanographic instruments were installed on the dock at the UM Rosenstiel School campus in 1994, and as an official NOAA CO-OPS station, water level measurements are verified and calibrated. The air and water temperature data are not verified and should be used with caution. These charts and tables utilize all available six-minute data and are updated daily. In order to be counted, a day is allowed up to 3 hours of data to be missing, and a month is allowed up to 2 days of data to be missing.
