ENSO and North Atlantic Hurricanes

Annual Cycle of Atlantic Hurricanes

The peak of the Atlantic hurricane season happens during the months of August to September, as seen in Figure 1, which shows the average number of hurricanes in the Atlantic per month from 1950-2001. The official hurricane season is defined from June to November, but hurricanes  occasionally form in other months.
