Meteorological Overview of Myrtle Beach in March

March marks the official meteorological and astronomical transition from winter to spring along the South Carolina coast. Located at approximately 33.68 degrees North latitude, Myrtle Beach experiences a humid subtropical climate. During March 2026, day length increases significantly, providing roughly 12 hours of daylight by the end of the month.

Atmospheric pressure systems begin to shift during this period. Continental polar air masses that dominate January and February weaken, allowing maritime tropical air from the Atlantic Ocean and the Gulf of Mexico to exert more influence. However, cold fronts still occasionally sweep down from the northern interior of the United States, producing rapid temperature drops and gusty winds before milder air returns.

Temperature Ranges and Daily Averages
