What Is the Bermuda High?


Many times, Meteorologist concentrate on areas of low pressure; however, the Bermuda High Pressure affects the weather tremendously in the southeast United States.

The Bermuda High, according to the National Weather Service, is “a semi-permanent, subtropical area of high pressure in the North Atlantic Ocean off the East Coast of North America that migrates east and west with varying central pressure.”

The Bermuda High is responsible for those hot and humid days across the southeast. Since we are predominately on the west side of the Bermuda High, winds are coming from the south, pushing warm air from the tropics northward. This also allows for scattered afternoon showers and storms.

The Bermuda High will sometimes slide to the west and center over the southeast, bringing extremely hot and dry conditions.

When the Bermuda High slides eastward, cold fronts can push into the area, bringing stronger showers and storms. Once the front clears the area, cooler and drier air will infiltrate from the west.

So, as you can see, the Bermuda High is very important for weather in the southeast during the summer time. It can bringing very hot and humid conditions, and it can allow cooler and drier air to move in.
