context_page_description: Key West is an island in the Straits of Florida, within the U.S. state of Florida. Together with all or parts of the separate islands of Dredgers Key, Fleming Key, Sunset Key, and the northern part of Stock Island, it constitutes the City of Key West.
  The Island of Key West is about 4 miles long and 1 mile wide, with a total land area of 4.2 square miles. It lies at the southernmost end of U.S. Route 1, the longest north–south road in the United States. Key West is about 95 miles north of Cuba at their closest points. It is also 130 miles southwest of Miami by air, about 165 miles by road, and 106 miles north-northeast of Havana.
  The City of Key West is the county seat of Monroe County, which includes all of the Florida Keys and part of the Everglades. The total land area of the city is 5.6 square miles. The official city motto is "One Human Family".
  Key West is the southernmost city in the contiguous United States and the westernmost island connected by highway in the Florida Keys. Duval Street, its main street, is 1.1 miles in length in its 14-block-long crossing from the Gulf of Mexico to the Straits of Florida and the Atlantic Ocean. Key West is the southern terminus of U.S.
context_section_description: Key West has a tropical savanna climate (Köppen Aw, similar to the Caribbean islands). Like most tropical climates, Key West has only a small difference in monthly mean temperatures between the coolest month (January) and the warmest month (July) – with the annual range of monthly mean temperatures around 15 °F (8.3 °C). According to the National Weather Service, the Florida Keys and Miami Beach are the only places within the contiguous United States to have never recorded a frost or freeze. The lowest recorded temperature in Key West is 41 °F (5 °C) on January 12, 1886, and January 13, 1981. Key West is located in USDA zone 11b (the warmest zone in the contiguous United States). According to the National Weather Service in Key West, low temperatures below 50 F (10 C) occur on average four times per decade.
  Prevailing easterly tradewinds and sea breezes suppress the usual summertime heating, with temperatures rarely reaching 95 °F (35 °C). There are 55 days per year with 90 °F (32 °C) or greater highs, with the average window for such readings June 10 through September 22, shorter than almost the entire southeastern U.S. Low temperatures often remain above 80 °F (27 °C), however. The all-time record high temperature is 97 °F (36 °C) on July 19, 1880, and August 29, 1956.
