You think you know Texas heat. You've seen the memes of mailboxes melting and steering wheels requiring oven mitts. But the temperature in Georgetown Texas is its own specific brand of chaos. It’s not just "hot." It’s a rhythmic, sometimes punishing, and occasionally confusing atmospheric dance that can see you wearing a heavy coat at 7:00 AM and short sleeves by lunch.
Georgetown sits right on the edge of the Texas Hill Country. This means we get the humid breath of the Gulf of Mexico clashing with the dry, sweeping winds from the West.
Honestly, the numbers on your weather app rarely tell the whole story. If the screen says 98°F, your skin is screaming 110°F because of the humidity. We call it "The Wall." You step outside, and the air just hits you. It’s thick. It’s heavy.
The Brutal Reality of August
August is the undisputed heavyweight champion of misery here. The average high technically sits around 95°F or 97°F, but that’s a bit of a lie. In reality, Georgetown frequently clocks weeks where the mercury stays north of 100°F.
Historically, we’ve seen some wild spikes. Did you know the record high for this area hit a staggering 113°F? That happened back in June 1980, but modern summers feel like they're constantly trying to beat that record.
When the temperature in Georgetown Texas stays triple-digit for ten days straight, the ground starts to crack. The limestone under our soil holds onto that heat. Even after the sun goes down, the radiation from the pavement keeps the "lows" at a stifling 75°F or 80°F. You never truly get a break.
Winter is a Wildcard
People move here from the North and laugh at our "winters." Then February hits.
Central Texas weather is famous for the "Blue Norther." This is a cold front that moves so fast it looks like a blue wall on the horizon. I’ve seen the temperature drop 40 degrees in two hours. You’ll be sitting at Blue Hole Park enjoying a 75°F afternoon, and by the time you drive home to Sun City, it’s 35°F and sleeting.
January is officially the coldest month. The average low is about 39°F. But averages are boring. The real story is the occasional Arctic blast. In 1949, Georgetown dropped to a bone-chilling -2°F. More recently, the 2021 freeze proved that our infrastructure isn't always ready for the "Short, Cold, and Windy" season. We don't get much snow—maybe an inch or two if we're "lucky"—but we get ice.
Spring and Fall: The "Goldilocks" Zones
If you’re visiting, aim for April or October.
April is spectacular. Highs hover around 79°F. The bluebonnets are out along Highway 29, and the air is actually breathable. It’s the sweet spot before the "Muggy Season" starts in June.

October is even better. The humidity finally breaks. The temperature in Georgetown Texas during October averages a perfect 80°F high and 59°F low. It’s patio weather. It’s the time of year when everyone in the Historic Square finally looks happy again instead of just sweaty.
Humidity: The Invisible Factor
We have to talk about the dew point.
Temperature is just a number; the dew point is a feeling. In the summer, Georgetown frequently sees dew points in the 70s. That is "oppressive" territory. When the air is that saturated, your sweat doesn't evaporate. You don't cool down.
- Under 55: Delightful. Dry. Rare in summer.
- 60 to 65: Noticeable. You'll feel the "Texas weight" on the air.
- Over 70: Tropical. Your hair will frizz instantly.
- 75+: Miserable. Just stay inside.
Survival Tips for the Georgetown Climate
If you're new here or just passing through, don't try to fight the weather. You will lose.

- Hydrate like it's your job. By the time you feel thirsty in a Georgetown July, you're already behind.
- The "10 to 4" Rule. Stay indoors between 10:00 AM and 4:00 PM during the summer. This is when the UV index is high enough to fry an egg on a Cedar Park sidewalk.
- Check the cedar count. In winter, "Mountain Cedar" pollen explodes when the temperature drops and the wind picks up. It’s called Cedar Fever, and it feels like a flu brought on by the weather.
- Dress in layers. Even in January, you might need a jacket for the morning commute and sunglasses for the drive home.
Basically, Georgetown weather is a test of patience. We pay for those gorgeous, mild spring days with a few months of feeling like we live on the surface of the sun. But hey, that’s why we have the San Gabriel River.
Actionable Next Steps: Check the local National Weather Service (NWS) Austin/San Antonio station for real-time "feels like" temperatures before planning outdoor hikes. If you are moving here, ensure your HVAC system is serviced in March; you do not want to find out it’s broken during the first 100-degree day in June. Lastly, keep a "winter kit" in your car—fleece blankets and water—because when a freeze hits Georgetown, the roads turn into ice rinks almost instantly.
