The 1975 Atlantic Hurricane Season was 50 years ago. This season was average due a La Nina. In fact, this was the same La Nina from 1973-1976. The La Nina peaked in 1975. Normally, a La Nina would favor above average seasons. However, 1975 is when the ASO was negative. In simple terms it was part of the cooling phase in the Atlantic Basin which was from 1970-1994. Thus, the La Nina allowed this season to be average.

Overall, there was 9 named storms, 6 became hurricanes, and 3 became major hurricanes. In 1975 an average season would have 9-10 named storms, 6 hurricanes, and 2 major hurricanes. Here is a list of all the known storms. *Beside a hurricanes name means the hurricane was a major hurricane category 3, 4, and 5.

Known storms from 1975.

TS Amy (6/27-7/4) pressure 981 millibars 70 mph. Amy was a typical June storm as it developed off the US Southeast Coast around the Gulf Stream. While Amy stayed out to sea it did get close to North Carolina where the storm caused a drowning due to rip currents.

Hurricane Blanche (7/24-7/28) Pressure 980 millibars 85 mph winds category 1 hurricane. Blanche formed around the Gulf Stream and moved northward. The Hurricane made landfall in Canada as a category 1 hurricane causing $6.2 million in damages.

*Hurricane Caroline (8/24-9/1) pressure 963 millibars, 115 mph winds category 3 hurricane. Carolina developed in the Gulf and made landfall in Mexico at peak intensity. Mexico reported 3 deaths from the storm but overall damage is unknown.

Hurricane Doris (8/28-9/4) pressure 965 millibars 110 mph winds category 2 hurricane. Doris developed in the Central Atlantic and stayed out to sea.

*Hurricane Eloise (9/13-9/24) pressure 955 millibars 125 mph winds category 3 hurricane. Eloise made landfall in the Dominican Republic as a category 1 hurricane. However, Eloise did almost all of its damage in the United States. Eloise made landfall in Florida at peak intensity. Eloise caused 80 deaths and $680 million in damages.

Hurricane Faye (9/18-9/19) pressure 969 millibars 105 mph winds category 2 hurricane. Faye developed in the far Atlantic and stayed out to sea.

*Hurricane Gladys (9/22-10/3) pressure 939 millibars 140 mph winds category 4 hurricane. Gladys developed in the far Atlantic and steadily intensified. The hurricane reached its peak in the Central Atlantic. The powerful hurricane stayed out to sea and caused no known impacts

Tropical Storm Hallie 1002 millibars 50 mph winds. Hallie formed off the South Carolina Coastline and stayed out to sea.

Sub Tropical Storm One (12/9-12/13) pressure 985 millibars 70 mph. An unnamed sub tropical storm developed in December. A subtropical storm is a storm that has some tropical storm characteristics but also resembles a non tropical low. Basically its a hybrid between a non tropical low and a tropical storm. This one stayed out to sea.

Overall the 1975 season caused around 90 lives and caused $700 million in damages. Most of the damage was from Eloise which caused almost all of the damage and deaths for the year. As stated the season was average due to a La Nina despite this being in the cooling phase.

The name Eloise was retired the following year due to its severe impacts in the state of Florida. While Eloise has been passed by other and stronger hurricanes. At the time Eloise was considered the worst hurricane to strike the Florida Panhandle in over 10 years. Also, Eloise is still talked about to this day.

The 1975 season was a huge technology advance year. Computer Models started to be used on a regular basis. This lead to more storms being detected and improved the accuracy of hurricane forecasting. Since then the models have become even more advanced. Therefore, the 1975 season allowed for better warning systems. It is hard to believe that this season was 50 years ago.
