Climate
Miami has a tropical climate, with warm, humid summers, and mild winters by most standards. The city does experience cold fronts from November through March, however most of the year is warm and humid, and the summers are reminiscent of a true tropical climate. In addition, the city sees most of its rain in the summer (wet season) and is mainly dry in winter (dry season). The wet season, which is hot and humid, lasts from May to September, when it gives way to the dry season, which features mild temperatures with some invasions of colder air, which is when the little winter rainfall occurs — with the passing of a front. The hurricane season largely coincides with the wet season.
In addition to its sea-level elevation, coastal location and position just above the Tropic of Cancer, the area owes its warm, humid climate to the Gulf Stream, which moderates climate year-round. A typical summer day does not see temperatures below 75 ºF (24 ºC). Temperatures in the high 80s to low 90s (30-35 °C) accompanied by high humidity are often relieved by afternoon thunderstorms or a sea breeze that develops off the Atlantic Ocean, which then allow lower temperatures, although conditions still remain very muggy. During winter, humidity is significantly lower, allowing for cooler weather to develop. Average minimum temperatures during that time are around 59 ºF (15 ºC), rarely dipping below 40 ºF (4 ºC), and the equivalent maxima usually range between 65 and 75 °F (18-24 °C).
Officially, Miami has only once recorded a triple-digit temperature, the all-time maximum being 100 ºF (37.8 ºC), set on July 21, 1942. However, extreme summer humidity often boosts the heat index to around 110 ºF (43 °C). The coldest temperature ever recorded in the city of Miami was 28 °F (-2 °C) on January 27, 1940. Miami has only once recorded snowfall, on January 20, 1977. Weather conditions for the area around Miami were recorded sporadically from 1839 until 1900, with many years-long gaps. A cooperative temperature and rainfall recording site was established in what is now downtown Miami in December, 1900. An official Weather Bureau Office was opened in Miami in June, 1911.
Miami receives abundant rainfall, one of the highest among major U.S. cities. Most of this rainfall occurs from mid-May through early October. It receives annual rainfall of 58.6 inches (1488 mm) , whereas nearby Fort Lauderdale and Miami Beach receive 63.8 in (1621 mm) and 48.3 in (1227 mm), respectively, which demonstrates the high local variability in rainfall rates. Hurricane season officially runs from June 1 through November 30, although hurricanes can develop beyond those dates. The most likely time for Miami to be hit is during the peak of the Cape Verde season which is mid August through the end of September. Due to its location between two major bodies of water known for tropical activity, Miami is also statistically the most likely major city in the world to be struck by a hurricane, trailed closely by Nassau, Bahamas, and Havana, Cuba. Despite this, the city has been fortunate in not having a direct hit by a hurricane since Hurricane Cleo in 1964. However, many other hurricanes have affected the city, including Betsy in 1965, Andrew in 1992, Irene in 1999, and Hurricanes Katrina and Wilma in 2005. In addition, a tropical depression in October of 2000 passed over the city, causing record rainfall and flooding. Locally, the storm is credited as the No Name Storm of 2000, though the depression went on to become Tropical Storm Leslie upon entering the Atlantic Ocean.
