The village has its own fire, police and public elementary and middle school. The millage tax rate remains one of the lowest of any municipality in Miami-Dade County. In 2004, the village completed the construction of a civic center including fire, police and administration buildings and a recreation and community center with indoor multi use courts, outdoor swimming pool and a renowned musical theater program. Climate Key Biscayne has a tropical monsoon climate (Am). Key Biscayne experiences hot, humid summers and warm, dry winters. The island is in USDA plant zone 11a. Due to its island location, Key Biscayne is subject to cooler highs than Miami year-round. Hurricanes threaten the island occasionally, though landfalls are rare. Precipitation is lower than that of Miami, as the Atlantic Ocean inhibits summer thunderstorm convection.
