You've probably heard that Georgia winters are basically a joke. People joke about the "pollen season" being the only real change, but if you're looking at the Augusta GA 30 day forecast right now, you know that's not exactly true. It's mid-January 2026, and the Garden City is acting a bit moody.
Honestly, planning a month out in the South is sorta like betting on a coin toss that’s currently mid-air. We are coming off a fairly wet start to the year—back on January 3rd, we already saw over half an inch of rain and some thick mist that made the morning commute feel like a scene from a noir film.
But what's actually coming up?

If you're looking at the stretch from late January into mid-February, you need to prepare for a bit of a seesaw. The National Weather Service and the Climate Prediction Center are tracking some serious Arctic air incursions that could dip further south than usual.
The Reality of the Augusta GA 30 Day Forecast
Most people think Augusta is just humid and hot. That’s the summer. In the winter, the "CSRA" (Central Savannah River Area) deals with a high-pressure tug-of-war.
Right now, the models are diverging. That’s a fancy way of saying meteorologists are low-key arguing. The GEFS and ECMWF models—the big heavy hitters in weather tech—can’t quite agree on how far that cold air is going to push. One model shows a "moderate risk" of much-below-normal temperatures for the northern tier of the US, but those 20% "cold push" probabilities are creeping down toward the Southern Plains and the Mississippi Valley.
For us in Augusta, that usually means a few things.
Expect a lot of "sunny but biting" days. Historically, our coldest day of the year is actually right around now, January 17th. Average highs sit near 57°F, but the lows? They average 38°F.
If that Arctic air wins the fight, don’t be surprised if those nighttime lows flirt with the mid-20s by the final week of January.
Rain, Clouds, and the Humidity Factor
One thing you can’t escape here is the moisture. Even when it’s cold, Augusta stays humid. We're talking an average relative humidity of 83% in January.
It makes the cold feel wetter. Heavier.

We are entering the wettest part of the year. While January starts with about a 26% chance of a "wet day," that climbs to 29% by the end of the month. February is actually statistically wetter. If you have outdoor plans for early February—maybe checking out the events at the Miller Theater or the Bell Auditorium—you’ll want to have a backup plan for rain.
Why the "Winter 2026" Outlook Matters
We are currently in a weak La Niña cycle. Usually, that means "warmer and drier" for the Southeast.
But "usually" is the keyword.
Climate Central has noted that Augusta’s winter average temperatures have actually risen by about 4.3°F since 1970. We have ten fewer freezing nights a year than our grandparents did. However, that warming also means the atmosphere holds more water. When it does rain, it pours. We're seeing an 18% increase in hourly rainfall intensity.
So, your 30-day outlook looks something like this:
- Late January: Highs in the mid-50s, but keep an eye on a potential cold snap around Jan 24-26. If the trough of low pressure from Canada digs deep enough, we’ll see those 20-degree nights.
- Early February: Temperatures likely to rebound into the low 60s. This is when the "Pine Straw" crowd starts getting restless.
- Precipitation: Expect at least 8 to 11 days of measurable rain over the next month.
What This Means for Your Calendar
If you’re heading to the Augusta Symphony Gala on January 24th, the forecast is currently leaning toward "chilly and potentially damp." You'll want a heavy coat for the walk from the parking deck to the Miller Theater.
For the Muscadine Bloodline fans hitting the Bell Auditorium on February 7th, the transition into February usually brings a slight "warm-up" (if you call 60 degrees warm), but that’s also when the Gulf moisture starts pumping back in.
Actionable Tips for the Next 30 Days
Don't just look at the "high" temperature on your phone and think you're good.
- Check the "Dew Point" over the humidity. If the dew point is in the 20s, it's going to be a "dry" cold that cracks your skin. If it's in the 50s during January, it's going to feel like a damp basement outside.
- Layers are non-negotiable. The temp can swing 30 degrees between 7:00 AM and 2:00 PM. A light shell over a fleece is the standard Augusta uniform for a reason.
- Watch the "Jan 24-30" window. This is the current "hazard" window for the eastern US. Even if we don't get the snow the North gets, we often get the high winds and the "wedge" of cold air that gets stuck against the Appalachian mountains.
The most important thing to remember? Augusta weather is inconsistent. We’ve had years where it’s 80 degrees in February and years where we have an ice storm that shuts down Washington Road for three days. Stay tuned to the local KAGS airport reports for the most granular data.
