The last month of hurricane season tends to not be very active, but some storms can develop. 

What You Need To Know

  • Cooler water temperatures and more shear lead to less activity

  • The Caribbean sees the best chances of development in November

  • The Central North Atlantic can also see some development

Water temperatures cool down rapidly in November, especially in the Gulf of Mexico.

However, the Caribbean stays warmer for longer, and that is where development is most likely late in the season, particularly in western portions. 

Thanks to the Gulf Stream, tropical development can also favor areas of the Atlantic off the southeastern United States coast. 

The central North Atlantic is another spot where late season development is possible.

The cooler water is not the only thing that suppresses tropical development late in the year. We can also blame shear.

High shear refers to faster upper-level winds, and this can affect tropical storm and hurricane formation.

Troughs and fronts will dip farther south into the tropics this time of year and they will typically bring a lot of shear along with it. 

Conditions can become favorable ahead and south of these fronts, but these will often steer hurricanes away from the United States late in the season. 

Hurricane season statistics

November is the last month of the hurricane season and you can see that tropical activity drops off significantly in the graph below.

However, it is not impossible to see activity outside of the season. It's just very infrequent.
