If you’ve ever spent more than five minutes in Stone County, you know the weather in Perkinston MS isn't just a topic of conversation—it's basically a local sport. One day you’re wearing a light jacket to grab coffee, and by 2:00 PM, you’re looking for a swimming pool because the humidity decided to show up uninvited. It's South Mississippi, after all.
Honestly, people from out of state usually get it wrong. They think "South" and assume it's just tropical paradise vibes year-round. It’s not. Perkinston has its own rhythm, dictated by the Piney Woods and the lingering breath of the Gulf of Mexico just a few miles south. It is a place where you learn to respect the sky.
The Reality of Perkinston Temperatures
Let's talk numbers, but keep it real. Perkinston doesn't usually do "extreme" cold, but the humidity makes 40°F feel like it’s biting through your bones. On the flip side, a 93°F day in July isn't just 93 degrees. It’s a thick, wet heat that sits on your shoulders.
January is officially the coldest month here. You’re looking at highs around 60°F and lows that hover near 41°F. That sounds mild, right? Tell that to the local gardener whose citrus trees just got hit by a surprise frost.
Then there’s July. July is a beast. The average high hits about 93°F, but with a 72% relative humidity level, the "feels like" temperature—the heat index—frequently storms past 105°F. It’s the kind of weather where you move from one air-conditioned box to another and hope for the best.

A Quick Breakdown of the Seasons
Winter usually feels like a series of cold fronts. One day it’s 70, the next it’s 35. Spring is gorgeous but short. By May, the heat is already revving its engine. Summer doesn't really leave until late October. That’s when the "Second Spring" or "False Fall" happens, which is arguably the best time to be outside.
Why the Rain in Perkinston MS is Different
You can't talk about weather in Perkinston MS without mentioning the rain. Perkinston gets a lot of it. We’re talking roughly 60+ inches a year. For context, that’s significantly more than the national average.
July is the wettest month. Why? Because of the "pop-up" thunderstorm. These aren't your typical all-day drizzles. These are violent, 30-minute deluges that turn the sky black, drop two inches of rain, and then vanish, leaving the sun to steam-cook the pavement.
Rain Averages You’ll Actually Notice
- March: Often the rainiest month in terms of volume (about 5.4 inches).
- July: The month with the most individual rainy days—usually around 17 days of rain.
- October: The hero of the calendar. This is the driest month, averaging only 3.2 inches. It’s the sweet spot for weddings and outdoor festivals.
Severe Weather: Beyond the Forecast
Living in Perkinston means keeping one eye on the National Weather Service in New Orleans/Baton Rouge. Because we are inland but close to the coast, we get the "best" of both worlds: hurricanes and tornadoes.

March, April, and May are the primary months for severe thunderstorms and tornadoes. There’s also a "second season" in November. Unlike the flat plains of Kansas, Perkinston is heavily wooded. This makes tornadoes particularly dangerous because you often can't see them coming over the tree line.
Then there’s hurricane season (June 1 to November 30). Perkinston is far enough inland to avoid the worst of the storm surge that hits Biloxi or Gulfport, but it’s right in the path for wind damage and inland flooding. Hurricane Katrina in 2005 proved that even 30 miles north of the beach, the weather can be catastrophic.
Planting and Growing in the Piney Woods
If you’re moving here and want to plant something, pay attention to the USDA Hardiness Zones. Perkinston sits in Zone 8b/9a. This is a transitional spot.
You’ve got a long growing season—nearly 250 days. You can grow tomatoes until Thanksgiving if you're lucky, but you also have to deal with fungal diseases that love the humidity. Native plants like Southern Magnolias, Azaleas, and Crepe Myrtles thrive here because they’ve evolved to handle the "wet feet" and the July bake-off.

Tips for Local Gardeners
- Mulch is your best friend. It keeps the roots cool when the sun is trying to turn your garden into a Crock-Pot.
- Water early. If you water at noon, you’re mostly just losing it to evaporation. If you water at night, you’re inviting mold.
- Watch the frost. Don't let a warm February fool you. There is almost always one last "Blackberry Winter" chill in March that will kill your tender seedlings.
What Most People Get Wrong
People think Perkinston is "always" sunny. Actually, July has the shortest amount of cloud-free hours. Between the humidity haze and the daily afternoon thunderstorms, the sky is often a milky white or a bruised grey during the height of summer.
Another misconception is that it never snows. It does—sorta. Maybe once every four or five years, we get a "dusting." It’s usually gone by noon, but it’s enough to shut down the schools and clear out the bread aisle at the local grocery store.
Actionable Insights for Handling Perkinston Weather
Knowing the weather in Perkinston MS is one thing; living with it is another. Here is how you actually navigate the climate without losing your mind:
- Invest in a Dehumidifier: Your AC works hard, but in a Perkinston summer, your indoor air can still feel heavy. A standalone dehumidifier makes a massive difference in comfort.
- The "Two-Shirt" Rule: If you’re working outside between June and September, you’re going to sweat through your first shirt by 10:00 AM. Bring a spare.
- Check Your Tires: Because it rains so hard and so fast, hydroplaning is a real risk on Highway 49. Make sure your tread is deep.
- Download a Radar App: Don't just check the "percent chance of rain." Look at the actual radar. If you see a cell forming over Wiggins, you’ve got about 15 minutes to get your car under a carport before the hail or heavy rain hits.
- Prepare for "The Big One": Keep a hurricane kit ready by May. This isn't being paranoid; it's just being a Mississippian. Water, batteries, and a way to cook without power are essentials.
To stay ahead of the curve, start tracking the local dew point rather than just the temperature. When the dew point hits 70°F, you’ll know it’s officially "sticky" season. If you're planning a visit or an outdoor event, aim for the last two weeks of October—it's the one time of year when the weather in Perkinston MS is almost guaranteed to be perfect.
