Hurricane Activity
Grand Cayman, Cayman Islands (MWCR)

Analyses of tropical systems passing within 60nm (= 60mi.) of the island per five year period. Used latitude/longitude coordinates (19.28N,81.35W) might not be the center of the island. Often the location of the island weather station was used, which is normally at the airport.
In the graphs below the number of tropical systems passing by are plotted for each 5 year period since 1851 and since 1945. This can show if there are more storms lately or which 5 year period in the last 150+ years was most active. Note that the last 'five year period' only consists of one year (2010). Those tropical systems reaching hurricane strength are in red, and the 'big ones' (severe hurricanes, or category 3 and up) in purple. A summary below the graph shows which 5 year period was most active, with the number of storms during that period between brackets.
See how this compares to all Atlantic storms, or for the Eastern Caribbean, Western Caribbean or the Bahamas/Turks&Caicos regions.

A separate part of the climatology section contains the actual storm tracks (all or per decade) and a weekly analysis to find out the peak of the hurricane season for Grand Cayman. See also how Grand Cayman ranks among other islands.
