Savannah in January is a bit of a tease. Honestly, you've probably heard the rumors about the "Hostess City of the South" having mild winters, but if you’re looking at the weather this week in Savannah GA, you’ll quickly realize that "mild" is a relative term that changes by the hour. One minute you're sipping a honey-lavender latte in a sundress, and the next you’re clutching a wool coat because a breeze rolled off the Savannah River and cut right through your soul.
It's weird.
Currently, as of Saturday evening, January 17, 2026, we’re sitting at a comfortable but humid 57°F. It's cloudy. A quiet 5 mph wind is coming out of the south, making the air feel a bit heavier than you’d expect for mid-January. If you’re out on River Street tonight, it’s actually pretty decent, but don't get used to it. The atmosphere is shifting, and the next few days are going to be a wild ride of plummeting temperatures and localized rain.
The Sunday Slump: Rain and a Reality Check
Tomorrow, Sunday, January 18, is where things get messy. Basically, if you had plans for a picnic in Forsyth Park, you might want to pivot to an indoor plan—maybe the American Prohibition Museum or a long lunch at The Olde Pink House.
We’re looking at a high of only 47°F. That’s a massive drop from today's high of 65°F.

The rain chance is sitting at a heavy 75% during the day. While some parts of Georgia are actually buzzing about a potential winter storm—yes, even the "S-word" (snow)—Savannah is expected to stay on the liquid side of that line. Meteorologists like Melissa Feito have been tracking this system closely, and while the Florida Panhandle and central Georgia might see some flakes, Savannah's "Lowcountry" status usually acts as a shield against the white stuff. Expect a cold, gray soaking instead.
By Sunday night, the rain clears out, but the thermometer keeps diving. We're hitting a low of 32°F. That’s freezing. Literally.
Early Week Chill: Sunny but Sharp
Monday, January 19, brings the sun back, but it’s a bit of a "fake out" sun. You’ll look out your window at those beautiful moss-draped oaks and think it looks warm. It won't be. The high is only 51°F, and with a 10 mph wind coming from the west, that "sunny" day is going to feel sharp.
Interestingly, there's a 0% chance of snow during the day, though the overnight lows continue to hover right at that 32°F mark. It's the kind of weather where the humidity makes the cold feel wetter and deeper than the dry cold you get out West.
Tuesday and Wednesday (January 20-21) keep us in that "winter-lite" pocket:
- Tuesday: Mostly cloudy, high of 52°F, low of 34°F.
- Wednesday: Fully cloudy, high of 57°F, low of 35°F.
Humidity starts creeping back up by mid-week, hitting around 72% on Wednesday. This is that classic Savannah dampness that makes 57°F feel like 45°F. Pack your scarves. Seriously.

The Weekend Warm-Up (The Savannah Seesaw)
If you can make it to Thursday, the reward begins. The weather this week in Savannah GA is characterized by these dramatic swings. Thursday hits 61°F, and by Friday, January 23, we’re back to a gorgeous, sunny 64°F.
But the real kicker? Saturday, January 24.
We are currently forecasting a high of 71°F for next Saturday. That is a 24-degree difference from the previous Sunday. This is why locals don't pack away their summer clothes in January; they just bury them under a couple of sweaters for three days at a time.
Why the Forecast Keeps Changing
If you’re checking your phone every two hours and seeing different numbers, don’t blame the app. Savannah is a coastal city. We have the Atlantic Ocean to our east and a whole lot of swampy river basin around us. These act as thermal buffers that drive local weather stations crazy.
According to historical data from the Savannah International Airport (KSAV), January is technically our coldest month, with average highs of 60°F. But "average" is just a math trick. In reality, we spend half the month at 45°F and the other half at 75°F.
Actionable Advice for the Next 7 Days
- Sunday is for Interiors: If you're a visitor, book your museum tickets for Sunday now. The Telfair Academy or the Jepson Center are perfect refuges from the 75% rain chance.
- The "Three-Layer" Rule: For Monday through Wednesday, you need a base layer, a warm mid-layer (fleece or wool), and a wind-blocking outer shell. The wind speed will be around 10-13 mph, which is enough to make the squares feel like wind tunnels.
- Protect Your Plants Sunday Night: With a low of 32°F, those tropical patio plants you bought during the warm spell last week need to come inside or be covered.
- Tybee Island Warning: If you're heading out to the coast, subtract about 5 degrees from the city forecast and add 10 mph to the wind speed. It will be bracing, to say the least.
The bottom line for the weather this week in Savannah GA is to prepare for a soggy Sunday followed by a crisp, cold start to the work week. By next weekend, you'll be back to outdoor dining and wondering why you were so worried about the cold in the first place.
Keep a close eye on the Sunday morning transition. If that rain lingers as the temperature drops, the bridges (especially the Talmadge Memorial Bridge) can get slippery, even if we don't see actual snow accumulation. Stay safe, stay dry, and keep a jacket in the trunk of your car—you're definitely going to need it before Friday.
