The 1921 Tampa Bay Hurricane — Tampa, Florida

The 1921 Tampa Bay hurricane came ashore near Tarpon Springs on Tuesday, October 25, 1921. The National Weather Service Tampa Bay office calls it the most destructive hurricane to hit the area since 1848. Its storm statistics list storm dates of October 20 to 30, 1921, a peak of 140 mph while the hurricane was a Category 4 over open water, and landfall winds of 120 mph, which made it a Category 3 at the coast.

Inside Tampa the wind was weaker than the water. The NWS records that the Tampa Weather Office at the time reported a peak wind of 75 mph with the storm, and its table lists 8.53 inches of rain at the Tampa Weather Bureau against 11.73 inches at St. Leo. The same table gives a maximum Tampa Bay storm surge of about 10.5 feet, and the surge, not the wind, did most of the damage along Hillsborough Bay.

The storm began over the western Caribbean. Bay News 9 reports that on October 23 an air pressure of 27.80 inches (941 mb) was observed in the Yucatan Channel, and that the hurricane is estimated to have been a Category 4 as it passed west of Cuba on October 24. From there it turned toward the Pinellas County coast, where the NWS places landfall near Tarpon Springs, north of the mouth of Tampa Bay.

Forecasting in 1921 rested on ship reports and memory. According to the NWS, most hurricane forecasts of the era were based on climatology, which suggested that cyclones moving over the Gulf tended to pass well north of Tampa. Tampa Historical notes that cable and radio made the 1921 hurricane one of the first in which residents received early notice, with the Associated Press relaying Washington weather bureau reports days ahead, yet no mandatory evacuation orders were given in Hillsborough County or anywhere else on the coast.

The newspapers of landfall morning show the gap. ABC Action News found that the St. Petersburg Times printed the headline City Escapes Big Hurricane on the day the storm arrived, and hours later downtown Tampa was flooded. Reporters researching the 2021 anniversary read the coverage on microfilm at the John F. Germany Public Library in downtown Tampa.

Bay News 9 reports that the surge inundated downtown Tampa with 10.5 feet of water, while parts of northern Pinellas County saw up to 11 feet. The most severe flooding from the storm surge took place in Palmetto Beach, Edgewater Park and Desoto Park, where the water rose to the second story of buildings. Breaking waves riding on top of the surge knocked down many structures in those East Tampa waterfront neighborhoods.

The port took a direct blow. The NWS names the steamer Favorite and the Thomas B. Garland among vessels smashed against the docks, describes boats moored in the Ybor Channel battered against the wharves, and reports that some vessels floated inland and were left beached as the water fell. The agency also states that waves from the Bay were almost breaking in the streets of Ybor City, and that water made its way into homes and businesses from Hyde Park, to Downtown Tampa, and into the fringes of Ybor City.

Street travel stopped. ABC Action News summarized the NWS surge map in 2021 with the line that city streets in Tampa became only navigable by boat. Bay News 9 adds that so much water piled into Tampa Bay that it crossed Pinellas County along the low bayou from Feather Sound toward the Gulf, briefly turning part of the county into an island.

Bayshore Boulevard was the most photographed casualty. In its seawall history, Hillsborough County records that developers began the first 1 mile of seawall, roadway and streetlights between Swann Avenue and Rome Avenue in 1907, and that the county added 2.3 more miles in 1912. The 1921 hurricane destroyed homes, brick road, trolley tracks, and the seawalls along the Hillsborough Bay, and a storm surge of 10 to 12 feet flooded Bayshore Boulevard and many houses in the Hyde Park neighborhood.

WFLA reported in 2023 that the resulting surge destroyed most of the seawall and sent water spilling over onto Bayshore Boulevard in Tampa, with coastal roads and trolley tracks left impassable; one of the archive photos it republished shows the Ballast Point trolley line. Rodney Kite-Powell of the Tampa Bay History Center told Bay News 9 that Bayshore did not have a unified seawall before the storm, and that the uniform look came only after the hurricane.

The rebuilding gave Bayshore its present shape. Hillsborough County states that the seawall was repaired and in some areas completely rebuilt, and that in 1926 Hillsborough County honored the completion of the southern end of the seawall with a historical marker. The same county timeline dates the seawall and balustrade from Howard Avenue to Gandy Boulevard to 1926, five years after the surge.

Electric service failed early. Tampa Historical cites a St. Petersburg Times report that water had flooded the ground floor of the Tampa Electric powerhouse by noon on October 25, and that utility workers shut down electricity to the entire county. The NWS photo record shows downed poles and trolley wires across Ybor City and notes that large trees were ripped out of the ground, including some in front of the Tampa Bay Hotel.

Losses reached farms as well as the waterfront. The NWS reports that the citrus industry was hard hit, and that salt water pushed inland by the surge kept some fields around Tampa Bay from producing in later seasons. Bay News 9 puts damage above $10 million in 1921 dollars, roughly $120 million in its 2022 estimate.

The NWS lists eight confirmed fatalities across the region, nearly half from drowning. Bay News 9 reports that two of those deaths were in Tampa, where people drowned in the surge.

The storm hit during the Florida land boom, and Tampa leaders worried about the city's image. Tampa Historical records that a campaign was initiated to minimize the earlier reports and to assure land investors and tourists that Tampa Bay was a year round destination. Bay News 9 reports that government officials and business leaders in Tampa turned down help offered by organizations and other cities, and Kite-Powell explained that boosters did not want the city seen as vulnerable to disasters.

The headlines that did run were blunt. ABC Action News lists Tampa City of Ruins and Bayshore Swept Clean among the post storm banners, and reports that on October 27, 1921, a report in the Tampa Daily Times quoted local weatherman W. J. Bennet saying a similar storm was not probable in Tampa again. Tampa Historical cautions that the boosterism makes the true local toll harder to reconstruct from the period newspapers.

The record survives in public archives in Hillsborough County. ABC Action News reports that the Burgert Brothers Photographic Collection at the Hillsborough County Public Library Cooperative holds the largest set of photographs of the storm, including the washed out Bayshore trolley line and flooded homes in Hyde Park. The NWS Preserve America pages explain that the Tampa Bay office, working with the University of South Florida, scanned two leather bound Weather Bureau books dating to 1890 and lists October 25, 1921 among its benchmark hurricanes.

Forecasters have also rerun the storm. Ahead of the 100th anniversary, the National Weather Service in Ruskin simulated the hurricane with the Weather Research and Forecasting model started from the NOAA Twentieth Century Reanalysis, and the NWS reports that the model storm made landfall on the correct date at the correct location near Tarpon Springs. NWS Meteorologist in Charge Brian LaMarre told ABC Action News in 2021 that the October 25, 1921 storm is the signature storm for the Tampa Bay area.
