caption_attribution_description: English: This map shows the tracks of all tropical cyclones in the 1933 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 1933 Atlantic hurricane season was the second-most active Atlantic hurricane season on record, behind only the 2005 season, with 20 storms forming in the northwest Atlantic Ocean, breaking the record set by 1887. The season also produced the highest Accumulated Cyclone Energy on record in the Atlantic basin, with a total of 259. The season ran through the summer and the first half of fall in 1933, with activity as early as May and as late as November. A tropical cyclone was active for all but 13 days from June 28 to October 7. The year was surpassed in total number of tropical cyclones by the 2005 season, which broke the record with 28 storms. Tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Because technologies such as satellite monitoring were not available until the 1960s, historical data on tropical cyclones from this period are often not reliable. Compensating for the lack of comprehensive observation, one hurricane researcher estimates the season could have produced 24 tropical cyclones.
  Of the 20 storms during the season, 11 attained hurricane status.

  Of the 20 storms during the season, 11 attained hurricane status. Six of those were major hurricanes, with sustained winds of over 111 mph (179 km/h). Two of the hurricanes reached winds of 160 mph (260 km/h), which is a Category 5–the highest of 5– on the modern Saffir-Simpson Hurricane Scale. The season produced several deadly storms, with eight storms killing more than 20 people. All but 3 of the 20 known storms affected land at some point during their durations.
