September 9th, 2017, after 11 years without hurricanes, Anna Maria Island was in the western wind field of Hurricane Irma, out of the storm surge quadrant but suffering downed trees and power outages. The Anna Maria City Pier was damaged beyond repair and is still not open to the public after 3 years of rebuilding, and unlet to a commercial tenant.

Anna Maria beach
A wide beach of accumulated sand and dunes resists storm erosion.

Currently the beaches of Anna Maria Island; Bradenton Beach, Holmes Beach and Anna Maria City, are in good shape, with increasing dunes of sea oats and wide sand deposits, which bodes well for resisting storm erosion and protection of turtle nesting.
