This is a list of all known or suspected Atlantic hurricanes before 1600. Although most storms likely went unrecorded, and many records have been lost, recollections of hurricane occurrences survive from some sufficiently populated coastal areas, and rarely, ships at sea that survived the tempests. Using sediment samples from Puerto Rico, the Gulf coast and the Atlantic coast from Florida to New England, Michael E. Mann et al. (2009) found consistent evidence of a peak in Atlantic tropical cyclone activity during the Medieval Warm Period followed by a subsequent lull in activity.
