Georgia's Wettest Region: The Northeastern Mountains and Piedmont

Where Does Georgia Get the Most Rain?

The northeastern part of Georgia—including the Blue Ridge Mountains and the northern Piedmont—receives the highest annual rainfall in the state: 50 to 70 inches, with some spots exceeding 80 inches.

Why This Region?

• Orographic Lift: Moist air from the Gulf of Mexico and Atlantic is forced up the mountains, cooling and condensing into heavy precipitation.
• Prevailing Winds: Consistently bring moisture inland.
• Proximity to Moisture Sources: Both the Gulf and Atlantic feed humid air masses.

This abundant rainfall supports lush forests, numerous waterfalls, and the headwaters of major rivers like the Chattahoochee and Savannah.
