The 1851 Atlantic hurricane season is the first season to be listed in the HURDAT archives, so it is the first officially listed season in the archives here. The official bounds of the season ran from June 15 to November 15, and the storms listed here are done so based off observations. Therefore, the data is incomplete, and relies on reports from significantly populated areas, or ships that rode out the storms as a result. Other storms have their peak intensities estimated, using the wind-pressure relationship, or the damage they caused if they made landfall in a populated area.
