If you’re moving to the Central Savannah River Area (CSRA) or just passing through, you’ve probably heard the rumors. People say Georgia is just one giant, humid swamp from May to October. Honestly? That’s only half the story. The weather in Martinez Georgia is a bit of a shapeshifter. It’s a place where you can experience a crisp, frost-covered lawn at 7:00 AM and be reconsidering your life choices in a t-shirt by noon.
Martinez sits right on the edge of Augusta, and its climate is technically "humid subtropical." But "technical" definitions don't tell you why your power bill spikes in August or why everyone panics when a single snowflake drifts past a streetlight.
The Summer Reality Check
Let’s not sugarcoat it: summer here is intense. From late May through mid-September, the air doesn't just sit there; it clings to you. July is officially the hottest month, with average highs hovering around 92°F or 93°F. That sounds manageable until you factor in the dew point.
In Martinez, the humidity often pushes the "feels like" temperature—the heat index—well into the 100s. It's the kind of heat that makes the steering wheel of your car feel like a stovetop burner.

Why the Rain Doesn't Always Help
You might think a summer afternoon thunderstorm would cool things down. Usually, it just turns the neighborhood into a giant sauna. These "pop-up" storms are a staple of Martinez life. One minute you’re looking at a clear blue sky, and the next, the bottom drops out.
- August is actually the wettest month on average, seeing about 6.23 inches of rain.
- June follows closely behind.
- The storms are often brief but violent, sometimes packing enough wind to knock down the pine limbs that loom over every driveway in Columbia County.
If you’re planning to do yard work or go for a run at Reed Creek Park, do it before 10:00 AM. Seriously. After that, you’re just swimming through the air.
When Martinez Actually Becomes Paradise
There is a window of time—short, but glorious—where the weather in Martinez Georgia is arguably the best in the country. This usually happens from mid-April to early June, and again from late September through October.
October is the "secret" best month. It’s the driest time of the year, with only about 2.5 inches of rain. The sky turns a deep, piercing blue that you just don't see in the hazy summer months. The highs sit in the comfortable 70s, and the nights finally drop back into the 50s. It’s perfect for the Columbia County Fair or just sitting out on a deck without getting eaten alive by mosquitoes.
The Spring Pollen "Snow"
Spring is beautiful but comes with a yellow price tag. Around March, the temperature starts hitting the high 60s, which is lovely. However, Martinez is densely packed with loblolly pines. For about three weeks, everything—your car, your dog, your lungs—will be coated in a thick layer of chartreuse pollen.
If you have allergies, March and April are your "indoor months." Even if the thermometer says it’s 72°F and perfect, the air quality index might tell a different story.
Winter: Short, Weird, and Occasionally Frozen
Winter in Martinez is a bit of a joke to people from the North, but it has its own quirks. January is the coldest month, with average highs of 58°F and lows around 38°F. You’ll get plenty of nights where it drops below freezing, but it rarely stays there during the day.
Snow? It’s a rare event. Usually, we get "wintry mix," which is just a fancy way of saying "cold rain that might make the bridges slippery." But when it does snow—even an inch—the town effectively shuts down. It’s not because people are scared; it’s because we don’t have the infrastructure (like salt trucks) to handle ice on the hilly roads leading toward Evans or Appling.
Staying Prepared: Actionable Insights for Martinez Residents
If you're living here, the weather isn't just something you check on your phone; it's something you manage. Here is how to actually handle the climate in this corner of Georgia:
- HVAC is King: Don't wait until June to service your AC. The high humidity in Martinez puts an incredible strain on cooling systems. If your unit isn't dehumidifying properly, you’ll end up with "sweating" windows and potentially mold in your attic or crawlspace.
- The "Two-Season" Wardrobe: You don't really need a heavy parka unless you're traveling. A medium-weight jacket and a collection of "light layers" will get you through 90% of a Martinez winter.
- Hydration is Non-Negotiable: If you're working outdoors in July, the humidity prevents your sweat from evaporating efficiently. This means your body can't cool itself down as well as it would in a dry heat. Drink more water than you think you need.
- Tree Maintenance: Given the frequency of severe thunderstorms and the occasional tropical remnant (like when Hurricane Michael blew through in 2018), keep your pines trimmed. A dead limb over your roof is a liability you don't want when a 50 mph gust hits.
- Timing Your Visit: If you are coming to visit family, target the "shoulder seasons." Late October or early May will give you the most "breathable" air and the best chance of clear skies for outdoor activities.
The weather in Martinez Georgia is a mix of southern hospitality and subtropical intensity. It’s a place where you’ll learn to appreciate a ceiling fan more than a fireplace and where "it’s not the heat, it’s the humidity" becomes your daily mantra. Keep an eye on the barometer, keep your umbrella in the car, and you’ll do just fine.
