The Atlantic Hurricane Season peaks between August and October, which places September right in the middle, and it is the one with an exceptional amount of activity. In fact, the Peak Day of the Atlantic Hurricane Season falls in September, on the 10th day.
So, why September? Well, two of the most noteworthy factors is wind shear and warm waters. As summer goes on, the variation of wind’s speed and direction weakens; and, water temperature rises. Not to mention, air temperatures are high, and moisture is in the atmosphere. Together, these create the perfect environment for strong, gusty storms.
Case in point: In 2018, 46% of the year’s named storms were alive in September. And two were making noise on September 10 – hurricanes Helene and Isaac.
