Weather Overview — Fort Lauderdale, Florida

Fort Lauderdale sits on Florida's southeastern Atlantic coast at the mouth of the New River, approximately 25 miles north of Miami, as Encyclopaedia Britannica documents. The city's position within Broward County, at elevations near sea level along the Atlantic Coastal Ridge, makes its weather patterns characteristic of the broader South Florida climate regime. The National Weather Service Miami/South Florida Forecast Office classifies Fort Lauderdale's climate as humid subtropical — a transition between the Köppen Af and Cfa designations — marked by warm temperatures throughout the year, high humidity, and a sharply defined wet season.

Instrumental weather records for Fort Lauderdale extend to 1912, giving the NWS climatological record more than a century of continuous observations. The current climate normals baseline used by the NWS for South Florida is the 1991–2020 period, replacing the earlier 1981–2010 normals, as the NWS Miami climate page notes. These normals establish the statistical expectations against which individual years and events are measured.

Fort Lauderdale's year divides into two climatologically distinct periods: a wet season spanning roughly June through September and a drier period from November through April, as described by the National Weather Service Miami/South Florida Forecast Office. May and October function as transitional months, with May showing increasing convective activity and October marking the gradual retreat of moisture.

During the wet season, daily afternoon and evening thunderstorms are the dominant weather pattern, driven by sea-breeze convergence between the Atlantic Ocean to the east and the Gulf of Mexico circulation to the west. These convective cells can produce heavy localized rainfall, frequent lightning, and brief but intense winds in a short period. The Atlantic hurricane season, which runs officially from June 1 through November 30, overlaps substantially with Fort Lauderdale's wet season, making the city periodically subject to tropical cyclone threats.

The dry season, November through April, is characterized by lower humidity, reduced rainfall, and milder temperatures. Frontal passages associated with mid-latitude weather systems occasionally penetrate South Florida during December through February, temporarily dropping temperatures into the 50s or lower and producing brief dry northwest winds. These fronts rarely bring the sustained cold that characterizes winter climates further north, and the NWS daily climatological reports for Fort Lauderdale show that freezing temperatures are historically rare within the city proper.

The NWS Climatological Report for Fort Lauderdale documents climate normals for the 1991–2020 baseline period and maintains an extremes record extending from 1912 through 2026. The normals indicate an average maximum temperature of 82°F in early April, consistent with the characteristically mild late-dry-season conditions the city experiences before summer heat builds. Summer maximum temperatures regularly reach into the low-to-mid 90s°F, with heat index values commonly exceeding those readings due to high relative humidity.

Annual precipitation is substantial, with the wet season months accounting for the majority of the yearly total. The NWS Fort Lauderdale-Hollywood Climate Plots provide graphical representations of monthly and annual precipitation against the long-term record, allowing year-to-year variation to be assessed against the 1912-onward baseline. Individual monthly totals during the wet season can reach or exceed ten inches in years with active tropical or convective patterns, while dry-season months may record fewer than two inches.

Fort Lauderdale's near-sea-level topography and extensive canal network make the city particularly vulnerable to flooding during high-rainfall events. The city's most documented recent extreme weather event occurred in April 2023, when more than 25 inches of rain fell in approximately 24 hours, as reported by the National Weather Service Miami/South Florida Forecast Office. The event caused widespread inundation of roads, Fort Lauderdale-Hollywood International Airport, and residential areas throughout the city. In the event's aftermath, Broward County and city officials initiated assessments of stormwater infrastructure capacity and resilience planning, according to the research brief sourced from NWS reporting.

Tropical cyclones represent a recurring hazard class. Fort Lauderdale's location on Broward County's Atlantic coast places it within the cone of potential impact for storms that develop in both the Atlantic basin and the Caribbean Sea. The city's recorded weather history, documented by the NWS historical records archive, spans more than a century of hurricane seasons. The Atlantic hurricane season's official June 1 through November 30 period encompasses the entirety of Fort Lauderdale's wet season. Outside of tropical systems, the city is also subject to severe thunderstorm events, waterspouts over nearshore Atlantic waters, and occasional rip current advisories affecting the approximately seven-mile Atlantic beachfront.

Flooding risk is amplified by the city's flat topography and the prevalence of impervious surfaces across developed urban areas. The April 2023 event was widely described by meteorologists as a historic outlier in the instrumental record, and it accelerated local dialogue about infrastructure resilience in the context of changing precipitation patterns.

The primary federal authority for weather forecasting and climate data in Fort Lauderdale is the National Weather Service Miami/South Florida Forecast Office, designated WFO MFL. This office issues all official forecasts, watches, warnings, and advisories for Broward County, and maintains the authoritative climate record for the Fort Lauderdale station. The office publishes daily climatological reports under the station identifier FLL, as well as the Fort Lauderdale-Hollywood Climate Plots that visualize the city's historical temperature and precipitation data against the 1991–2020 normals.

The NWS daily climatological report for Fort Lauderdale documents observed high and low temperatures, precipitation totals, and comparisons to the 1991–2020 normal values and to the all-time records extending back to 1912. These reports constitute the official public record of daily weather conditions at the Fort Lauderdale station. Broward County's emergency management operations also draw on NWS data when activating local warning protocols during tropical weather events and severe thunderstorm outbreaks.

Fort Lauderdale's weather patterns are broadly shared with neighboring municipalities across Broward County and the wider South Florida metropolitan region. The cities of Hollywood to the south, Oakland Park and Lauderdale-by-the-Sea to the north, and Davie and Plantation to the west all fall within the same NWS Miami/South Florida Forecast Office coverage area and experience comparable seasonal rainfall cycles, hurricane exposure, and temperature regimes. Miami-Dade County, directly to the south, and Palm Beach County, to the north, are served by the same NWS forecast office and share the humid subtropical climate classification.

The city's geography, particularly the 165 miles of navigable inland canals documented by the City of Fort Lauderdale and the proximity of Port Everglades — one of the busiest cruise and cargo ports on the southeastern U.S. coast — means that weather events carry economic dimensions beyond residential impacts. Storm surge associated with tropical cyclones is a recognized threat for low-lying coastal and waterway-adjacent properties. The April 2023 flooding event demonstrated that even non-tropical precipitation extremes, when sufficiently intense, can disrupt airport operations, major road corridors, and neighborhoods across a city where virtually no terrain rises significantly above sea level, as noted in the Encyclopaedia Britannica description of the city's Atlantic Coastal Ridge topography.
