Of the 32 hurricanes NOAA records in South Carolina since 1851, 32 arrived in months our season rule marks as in the water at Columbia (Apr, May, Jun, Jul, Aug, Sep and Oct). At Charleston the count is 32 in months in the water. 5 have come since 2000 and 5 were Category 3 or stronger.
In NOAA's record, South Carolina impacts fall most often in September (13), August (10) and October (5). A boat at Columbia is in the water in all three by our season rule, and in the water in 5 of the 6 season months overall, so settle storage before June 1.
