Tropical Cyclone Climatology

The official hurricane season for the Atlantic Basin (the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico) is from June 1st to November 30th.

The peak of the season is from mid-August to late October. However, deadly hurricanes can occur anytime in the hurricane season.

National Data Buoy Center

NDBC provides hourly observations from a network of about 90 buoys and 60 Coastal Marine Automated Network stations. All stations measure wind (speed/direction/gust) and barometric pressure and air temperature.

Storm Surge

Along the coast, storm surge is often the greatest threat to life and property from a hurricane. The size of a storm surge for a particular location depends on a number of factors. Storm surge is very sensitive to the shape of the coast, and to changes in storm track, intensity, forward speed, and size. Tidal height at the time of maximum storm surge is an important factor.
