Cross Hill is a tiny spot on the map in Laurens County, but if you’ve lived here or even just passed through on your way to Lake Greenwood, you know the climate is its own beast. People assume South Carolina is just "hot" and "hotter." That's a mistake. Honestly, the weather in Cross Hill SC is a moody mix of swampy humidity, sudden spring thunderstorms, and winters that can actually bite when you aren't looking.
It’s a humid subtropical climate. Basically, that means you’re going to sweat through your shirt in July, but you might also see a dusting of snow in January—even if it’s only an inch.

The Summer Slog and the "Dew Point" Trap
July in Cross Hill is heavy. There’s no other way to put it. You’ll see average highs hitting around 91°F, but that number is a liar. It doesn't account for the moisture coming off the nearby lake or the general South Carolina "funk."
Dew points regularly climb above 65°F during the peak of summer. When that happens, your sweat just... stays there. It won't evaporate. You feel like you're walking through a warm, wet blanket. Nighttime doesn't offer a massive escape either, with lows hovering near 69°F or 70°F. If you’re planning a move here, make sure your HVAC system is in top shape before June hits. You'll need it.
Why the Weather in Cross Hill SC Makes Spring and Fall So Sweet
If summer is the tax you pay to live here, spring and autumn are the refund. Mid-March to May and late September through October are, quite frankly, the only times you’ll want to be outside for more than ten minutes.
- The Spring Transition: Temperatures jump from the 50s to the 70s quickly. By April, you’re looking at gorgeous 74°F days. But watch out. This is also when the atmosphere gets "angry."
- The Severe Threat: We aren't in "Tornado Alley," but Laurens County gets its fair share of severe thunderstorm warnings. In March and April, cold fronts from the northwest clash with that warm, moist air from the Gulf. Result? Big hail and the occasional spin-up.
- The October Sweet Spot: October is statistically the driest month. It’s crisp. Highs are around 74°F, and the humidity finally takes a hike. It's the best time to hit the water at Lake Greenwood without feeling like you're being steamed alive.
Winter: More Than Just "Chilly"
Don’t let the southern location fool you into thinking you won't need a real coat. January is the coldest month. Highs average 54°F, which sounds fine, but the lows dip to 32°F or 33°F. It’s a damp cold. It gets into your bones.
Snow is rare. We get about an inch a year on average. Usually, it's that "sneaky" winter weather—freezing rain or sleet—that causes more trouble than actual snow. Because the ground doesn't stay frozen, we get a lot of "black ice" on the backroads around Cross Hill. If the forecast mentions "wintry mix," locals generally stay off the roads. It's just safer.
Rain Patterns and the Garden Factor
We get about 46 inches of rain a year. It’s pretty well-distributed, though December and March tend to be the wettest. For gardeners in the 29332 zip code, the frost dates are the real "bible."
Usually, your last spring frost happens around late March or early April. If you plant your tomatoes before April 15th, you’re gambling. I've seen many "eager beaver" gardeners lose an entire flat of peppers to a rogue frost in the first week of April. On the flip side, the first fall frost usually doesn't hit until late October or early November. This gives us a massive growing season—roughly 220 days.
Survival Tips for Cross Hill Weather
If you’re new to the area or just visiting, keep a few things in mind. The sun here is intense. Even on a 75-degree day in May, you’ll burn faster than you think.
- Check the Radar: Afternoon "pop-up" storms are a staple of Cross Hill summers. They aren't always forecasted, but they’ll drop two inches of rain in twenty minutes and then disappear.
- Hydrate: This sounds like a cliché until you're lightheaded at a backyard BBQ.
- Watch the Lake: If you’re out on Lake Greenwood, keep an eye on the horizon. Storms can move in fast over the water.
The weather in Cross Hill SC defines the rhythm of life here. You learn to embrace the slow, sticky afternoons of August because you know those perfect, golden October days are right around the corner.
Next Steps for Staying Weather-Ready:
Start by checking your home’s insulation and HVAC filters now, especially if you're heading into the humid summer months or the damp January chill. If you’re a gardener, mark April 15th on your calendar as your "safe" planting date to avoid the heartbreak of a late-season frost.
