caption_attribution_description: English: This map shows the tracks of all tropical cyclones in the 1921 Atlantic hurricane season. The points show the location of each storm at 6-hour intervals. The colour represents the storm's maximum sustained wind speeds as classified in the Saffir-Simpson Hurricane Scale (see below), and the shape of the data points represent the nature of the storm.

context_page_description: The 1921 Atlantic hurricane season featured the most recent major hurricane to strike the Tampa Bay Area in Florida. Although no "hurricane season" was defined at the time, the present-day delineation of such is June 1 to November 30. The first system, a tropical depression, developed on June 1, while the last, a tropical storm, dissipated on November 25. Of note, three of the twelve cyclones co-existed with another tropical cyclone during the season.
  Of the season's twelve tropical cyclones, seven became tropical storms and five strengthened into hurricanes. Furthermore, two of these strengthened into a major hurricane—Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale—the most since the 1917 season. The strongest hurricane of the season, Hurricane Six, peaked as a low-end Category 4 with winds of 140 mph. Throughout Florida, the hurricane left about $10 million in damage and eight deaths. Two other cyclones left extensive impacts. Although not a tropical cyclone at the time, the remnants of the second hurricane contributed to a devastating flood in the Greater San Antonio area of Texas, which resulted in $19 million in damage and 215 fatalities.

  Of the season's twelve tropical cyclones, seven became tropical storms and five strengthened into hurricanes. Furthermore, two of these strengthened into a major hurricane—Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale—the most since the 1917 season. The strongest hurricane of the season, Hurricane Six, peaked as a low-end Category 4 with winds of 140 mph (230 km/h). Throughout Florida, the hurricane left about $10 million (1921 USD) in damage and eight deaths. Two other cyclones left extensive impacts. Although not a tropical cyclone at the time, the remnants of the second hurricane contributed to a devastating flood in the Greater San Antonio area of Texas, which resulted in $19 million in damage and 215 fatalities. The third hurricane left thousands homeless in the Lesser Antilles and caused at least 81 deaths.
  The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 87. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. It is only calculated for full advisories on tropical systems at or exceeding 39 mph (63 km/h), which is tropical storm strength.
