Factors Affecting Saint Simons Island Weather

The Saint Simons Island weather is influenced by several key factors:

Proximity to the Atlantic Ocean

Being a coastal island, the Atlantic Ocean significantly moderates temperatures. It keeps the island from experiencing extreme cold in winter and extreme heat in summer compared to inland locations. However, it also contributes to the high humidity levels, especially during warmer months.

Gulf Stream

The nearby Gulf Stream Current also plays a role, bringing warmer waters that contribute to the mild winters and humid summers. This oceanic influence is a primary driver of the subtropical climate. — Canelo Fight Time: Get Ready For The Main Event!
