Climate & Weather in Augusta
Augusta has a humid subtropical climate with hot, humid summers and mild winters. Aggregated climate data reviewed this session cites a January average high around 58°F and low around 36°F, and a July average high around 93°F and low around 72°F -- squarely the hot, long-summer pattern typical of inland Georgia, without the moderating coastal influence Savannah gets from the Atlantic.

Learn moreSummer: Hot, Humid, and Long
Augusta's warm season runs roughly May through September, with July the hottest month -- average highs around 93°F and lows around 72°F per climate data reviewed this session. Humidity is a real, year-round factor in daily comfort and air-conditioning costs, consistent with the broader inland-Southeast pattern, though Augusta lacks the direct coastal humidity moderation Savannah experiences.
Winter: Genuinely Mild, With Occasional Cold Snaps
January, Augusta's coolest month, averages a high around 58°F and a low around 36°F -- mild by national standards, though inland Georgia's winters run measurably cooler than coastal Savannah's in this same batch, and occasional hard freezes are real, if infrequent.
Severe Weather Season Overlaps Spring and Hurricane Season
As detailed on the flood-hurricane-risk topic page, Augusta's peak severe-thunderstorm and tornado season runs roughly March through May, with a secondary risk window during Atlantic hurricane season (June 1-November 30) when tropical-system-spawned tornadoes and, occasionally, direct tropical-storm impact (as with Hurricane Helene in September 2024) are possible even this far inland.
Humidity as a Year-Round Factor
Augusta's humidity moderates somewhat in the comparatively drier winter months but is a real, present factor across most of the calendar -- a genuine adjustment for anyone relocating from a drier or more northern climate, and a real driver of air-conditioning costs (see the cost-of-living topic page).
