You’re driving down Highway 82, the sun is beating against the windshield, and you’re pretty sure you could fry an egg on the dashboard. That’s just a Tuesday in Brantley County during July. People think they know the South, but the weather for Nahunta Georgia is its own kind of beast. It’s not just "hot"—it’s a swampy, thick, 92-degree blanket that feels like a physical weight on your shoulders. Honestly, if you aren't prepared for the specific quirks of this corner of Georgia, you’re going to have a rough time.
I’ve spent enough time looking at the data—and feeling the humidity—to tell you that Nahunta doesn't play by the rules you might find in Atlanta or even Savannah. We are tucked inland just enough to lose the coastal breeze but close enough to the coast to get hammered by the moisture. It’s a delicate, sweaty balance.
The Reality of the Nahunta Summer (It’s Not Just the Heat)
Most folks look at a forecast and see 93°F and think, "I can handle that." In Nahunta, 93 degrees is a lie. Because of our proximity to the Satilla River and the surrounding wetlands, the dew point here regularly sits in the 70s during the peak of summer.
When the dew point hits 72°F or 73°F, your sweat doesn't evaporate. It just stays there. You’re basically wearing your own personal sauna.
From late May through mid-September, the "hot season" is relentless. July is statistically the peak, with average highs of 92°F, but the overnight "lows" rarely dip below 71°F. That means the ground never really cools off. You wake up at 6:00 AM, and it’s already muggy.
- The Afternoon Monsoon: If you’re planning a cookout between June and August, do it early or late. Between 2:00 PM and 5:00 PM, the heat builds up so much energy that the sky just gives up. You’ll get these massive, 20-minute downpours that drop an inch of rain and then vanish, leaving the air even steamier than before.
- The "Comfort" Window: If you want to actually enjoy being outside without needing a second shower, aim for late March to May. The humidity hasn't quite ramped up yet, and the highs sit in that sweet spot between 72°F and 80°F.
Why Winter in Nahunta is Sneaky
Don't let the "Short Winter" label fool you. While our cold season only lasts about three months (roughly the end of November to late February), it can get surprisingly crisp. January is the coldest month, and while the average high is a pleasant 63°F, the nights will drop to 41°F or even lower.
We rarely see snow—in fact, the annual average is basically zero—but we do get hard freezes.

The last freeze usually happens sometime in March. For the gardeners around here, that’s the date that matters. If you put your tomatoes in the ground too early because you had one 80-degree day in February, a late-season frost will wipe you out.
The Hurricane Factor and Severe Storms
Nahunta sits about 40 miles inland from the Atlantic. We aren't on the front lines like Brunswick or St. Simons, but that doesn't mean we're safe. Actually, being inland can be weirder. When a tropical system moves in, it often slows down.
August and September are the months to watch. August is actually our wettest month, averaging over 7 inches of rain. A lot of that comes from tropical moisture. While the coast gets the storm surge, Nahunta gets the flooding and the wind. Because we have so many tall pines and oaks in the area, a 50-mph gust—which is "minor" for a hurricane—can still knock out your power for three days by dropping a limb on a line.
Honestly, the bigger threat is often the tornadoes spawned by these systems. They pop up in the outer rain bands with almost zero warning. It’s why every house in Brantley County should have a weather radio that works when the Wi-Fi dies.

January starts the year with highs around 63°F. It’s often gray and a bit damp. By March, things are waking up, and you’re looking at 72°F highs. This is arguably the best month of the year.
Once you hit May, the mercury jumps to 86°F. By June, you’re at 90°F, and you stay there until September. October brings a massive relief—the temperature drops back to 79°F, and the humidity finally breaks.
- Rainfall: We get about 52 to 53 inches of rain a year. That’s a lot. Most of it comes in the summer "thumpers" and late-summer tropical systems.
- Sunshine: We get nearly 3,000 hours of sunshine a year. It sounds lovely until you’re the one mowing the grass in July.
- Cloud Cover: October is our clearest month. If you’re into stargazing or just want a clear blue sky, that’s your window. July is actually the cloudiest, mostly because of all that rising moisture forming afternoon thunderheads.
Survival Tips for the Brantley County Climate
If you're moving here or just visiting, there are a few things you have to do differently.
First, the sun is stronger than you think. We aren't that far north of the Florida line. You can get a sunburn in February if you stay out long enough.
Second, the "Pollen Apocalypse" is real. In late February and March, everything in Nahunta turns a sickly shade of neon yellow. The pine pollen is so thick it looks like smoke when the wind blows. If you have allergies, keep your windows shut and your AC filters clean.

Lastly, watch the Satilla River levels. When we get heavy rains up-state, the river can rise even if it hasn't rained a drop in Nahunta. Local flooding on dirt roads is common during the wet season.
Actionable Steps for Dealing with Nahunta Weather
- Check your AC early: Don't wait until the first 90-degree day in May to see if your unit works. Every HVAC tech in the county will be booked solid. Test it in late March.
- Tree Maintenance: Given our susceptibility to tropical wind and summer squalls, trim any branches hanging over your roof. Pine trees love to snap in high winds.
- Hydration is non-negotiable: If you’re working outside in the summer, you need to drink twice as much water as you think. The humidity prevents your body from cooling itself efficiently.
- Monitor the Frost: If you’re planting, wait until after the third week of March to be safe, or keep some frost blankets handy for those surprise 30-degree nights.
- Emergency Kit: Since power outages are common during storm season, keep a kit with at least three days of water, flashlights (not candles), and a battery-powered fan. Trust me, you do not want to be in a Nahunta house in August with no power and no fan.
Basically, the weather here is a test of endurance in the summer and a beautiful, mild gift in the spring and fall. Just don't let the "winter" fool you into thinking you won't need a heavy coat at least a few times a year. Stay hydrated, keep an eye on the radar, and enjoy those rare, breezy October afternoons when they finally arrive.
