You’re driving down Highway 278, windows down, thinking you’ve got the Georgia climate all figured out. Then the humidity hits you like a wet wool blanket. Or maybe it’s mid-January, and you’re scraping a surprisingly thick layer of frost off your windshield while the thermometer mocks you with a brisk 26 degrees. Most folks think of Georgia as a land of perpetual peach-fuzz warmth, but the weather in Union Point GA has a personality that’s a bit more... temperamental.
Honestly, it’s a town of 1,600 people that lives and breathes by the sky. Whether you're here for the history or just passing through Greene County, understanding the local atmosphere isn't just about packing a jacket; it’s about surviving the "dog days" and knowing why October is the real MVP of the calendar year.
The "Hottest Month" Myth and the July Reality
People love to complain about August, but if we’re looking at the hard data, July is the real heavyweight champion of heat here. We’re talking about an average daily high of 91°F, but that number is a liar. It doesn't account for the "feels like" factor. Because Union Point is tucked into the Piedmont region, the moisture trapped in the air can push the heat index well into the triple digits.
During these weeks, the air feels thick. Stationary.
You’ve probably heard the term "muggy," but in July, Union Point reaches "oppressive" levels of humidity about 89% of the time. It’s the kind of weather where you walk from your front door to your car and somehow end up needing a second shower. If you’re planning a visit, this is the time to embrace the "porch life"—find a fan, grab some iced tea, and don't even think about moving between 2:00 PM and 6:00 PM.
Why July is the Wettest (and Weirdest)
Surprisingly, the heat brings the rain. July is actually the month with the most wet days, averaging about 12.6 days of precipitation.

But don't expect a cozy, all-day drizzle.
These are those classic Southern "pop-up" thunderstorms. One minute the sun is scorching the asphalt, and the next, the sky turns a bruised purple and dumps two inches of rain in twenty minutes. By the time you find your umbrella, it’s over, and the sun is back out, turning the puddles into steam. It’s a cycle.
Winter in Greene County: It’s Colder Than You Think
If you come from the North, you might laugh at a Georgia winter. Until you spend a night in Union Point in January.
The average low sits around 38°F, but it’s the humidity that makes it bite. It’s a "wet cold" that gets into your bones. While snowfall is rare—officially averaging near 0 inches most years—we do get the occasional dusting or, more dangerously, ice storms.
"The coldest day of the year usually hits around January 17th," notes local climate tracking data. On those nights, temperatures can dip into the 20s.

It’s not uncommon to see a "Dense Fog Advisory" on a January morning. The National Weather Service often warns of visibility dropping to less than a quarter mile. If you're driving near the Oconee National Forest early in the morning, that fog is no joke. It's thick, gray, and hides deer like a professional magician.
Spring and Fall: The Golden Windows
If you want to see the weather in Union Point GA at its absolute best, you have two very specific windows.
- Late April to early June: This is when the dogwoods and azaleas are showing off. The highs are in the comfortable 70s and low 80s.
- Late August to late October: This is the local favorite.
Specifically, October is arguably the most perfect month in East Georgia. The sky is clear about 65% of the time—the clearest it gets all year. The humidity finally breaks, the mosquitoes pack their bags, and you get those crisp 55-degree mornings followed by 75-degree afternoons. It’s peak "football weather."
The Gardening Clock
For the green thumbs, this weather dictates everything. According to the UGA Cooperative Extension, you’ve basically got two seasons. You plant your tomatoes and peppers in late March or early April (once that last frost risk dies down), and then you do it all over again in late July for a fall harvest.
But watch out. If you plant your fall crops later than July 20th, you’re gambling with the first frost, which usually creeps in by mid-November.

Severe Weather: The Stuff Nobody Talks About
We can't talk about Georgia weather without mentioning the sirens. Greene County, including Union Point, sits in a zone where severe thunderstorms are a regular part of life.
In the last year alone, the Greensboro/Union Point area has been under severe weather warnings dozens of times. We're talking 60 mph wind gusts that can peel shingles off a roof or drop a century-old oak tree across a power line.
- Hail: It happens more than you’d think. Radar has detected hail in the vicinity over 60 times in a single year.
- Tornadoes: While not "Tornado Alley," the spring months (March through May) bring a legitimate risk. These storms move fast—sometimes at 75 mph—so having a weather app with push notifications isn't just a good idea; it's a necessity.
A Month-by-Month Cheat Sheet
To keep it simple, here’s how the year actually feels on the ground in Union Point:
- January: Gray, damp, and chilly. Expect highs of 56°F and lots of morning fog.
- February: The wettest month for actual rainfall volume (4.3 inches). It’s muddy and unpredictable.
- March: Windy. Like, 11 mph average wind speeds. It’s the "transitional" month where you’ll wear a coat at 8 AM and shorts at 2 PM.
- April: Perfection begins. Highs around 75°F. Pollen becomes a literal yellow blanket on every car.
- May: Getting warmer (82°F). The last "safe" month before the humidity turns into a monster.
- June: Summer is here. Highs of 88°F. The afternoon storms start to become a daily ritual.
- July: The peak. 91°F highs, 71°F lows. Stay inside.
- August: Just as hot as July, but slightly drier. The "Dog Days" are real.
- September: A slow cooling. 84°F. You can finally breathe again.
- October: The sweet spot. 75°F and clear blue skies. If you're visiting, come now.
- November: Brisk. 66°F. The leaves turn, and the air gets thin and sharp.
- December: Back to the 50s. It’s "moderately chilly" and humid.
Actionable Tips for Navigating Union Point’s Climate
If you’re moving to the area or just visiting, don't rely on a generic national forecast. The microclimate here is real.
First, invest in a high-quality dehumidifier if you’re living in an older home. The Greene County humidity is relentless and will find its way into your closets. Second, keep a "car kit" that includes both an umbrella and a scraper. You’ll likely use both in the same week during March. Third, if you're planning outdoor events, always have a "Plan B" for the hours between 4:00 PM and 6:00 PM in the summer—those lightning storms don't care about your barbecue.
Finally, bookmark the National Weather Service's Peachtree City station. They handle the Greene County forecasts and are far more accurate for our specific slice of Georgia than the big national apps. Knowing whether that cloud is a 20-minute shower or a 60-mph wind event makes all the difference when you're out on the porch.
