Peak of Hurricane Season

MYRTLE BEACH, SC (WMBF) – Although the Atlantic Hurricane Season technically lasts from June 1 to November 30, there is historically a pronounced peak in tropical activity in the Atlantic around September 10.

September 10 is typically the peak of Hurricane Season for several reasons. First, ocean temperatures in the topics tend to reach their peak in early to mid September, after the water has been warmed all summer. Second, the African easterly jet reaches its peak intensity in early September and generates tropical waves off the west coast of Africa, which is where tropical systems tend to get their start in the Atlantic. Third, the deep-layer wind shear that typically disrupts systems during early hurricane season tends to weaken, which otherwise tends to disrupt the core of thunderstorms around an area of low pressure, keeping systems from developing or from becoming significant.

During this time, the most common area of development is the Atlantic Basin, from the west coast of Africa to the Gulf of Mexico.

On average, another five named storms, three of which are hurricanes (and one major hurricane) will develop after the September 10 peak. All together, about 61 percent of all named storms in the Atlantic since 1950 have occurred in either August or September.
