If you’ve spent more than five minutes in DeSoto County, you already know the deal. The sky can go from a clear, crisp blue to a bruised purple in about the time it takes to grab a sweet tea at McAlister’s. People check the olive branch ms weather forecast like it’s a full-time job because, honestly, the atmosphere here is incredibly moody. We are sitting right in that sweet spot—or maybe sour spot, depending on your perspective—where the humid air from the Gulf of Mexico decides to pick a fight with the cold fronts sweeping down from the Great Plains. It makes for some interesting Tuesdays.
You’re basically living in a transition zone.
Geographically, Olive Branch is tucked into the extreme northwest corner of Mississippi. It’s part of the Memphis metropolitan area, which means we share that classic Mid-South climate: humid subtropical. But because Olive Branch sits just a bit higher and more "in the country" than downtown Memphis, you’ll often see a degree or two of difference. It’s enough to make a difference when you're deciding whether to cover your hydrangeas or leave them to the elements.
The Reality of Spring: More Than Just Pollen
Spring in Olive Branch is gorgeous. It’s also stressful.
Around late March, the Bradford Pears start blooming and everyone starts sneezing. But the real story with olive branch ms weather in the spring is the volatility. This is peak severe weather season. We are located in what some meteorologists call "Dixie Alley." Unlike the traditional Tornado Alley in the Plains, our storms often happen at night and can be wrapped in heavy rain, making them harder to spot.
Local experts like those at the National Weather Service in Memphis frequently point out that the confluence of warm, moist air and strong atmospheric shear creates a playground for supercells. You have to stay weather-aware. It’s not just a buzzword here; it’s a lifestyle. Most locals have at least two different weather apps—usually a mix of a major outlet and a local favorite like MemphisWeather.net—plus a physical NOAA weather radio.
- March: Highs average in the mid-60s, but it's the wettest month of the year.
- April: The "sweet spot" before the humidity turns into a physical weight. Highs jump to the low 70s.
- May: This is when you start feeling the first real "heats." Expect highs in the 80s and the occasional 90-degree day that catches you off guard.
Don’t let the sunshine fool you. A morning that starts at 65°F can end with a siren at 6:00 PM. It’s the price we pay for the lush green lawns and the blooming azaleas that make the Old Towne area look like a postcard.
Survival Guide for an Olive Branch Summer
If you aren't from the South, "humidity" is just a word. If you live here, it’s a sentient being that wants to ruin your hair and melt your makeup.
By late June, the olive branch ms weather settles into a predictable, sweltering rhythm. We’re talking highs consistently in the 90s. But the "real feel" or heat index? That’s the number that actually matters. When the humidity hits 70% and the temperature is 95°F, it feels like you're breathing through a warm, damp washcloth. It’s intense.
Actually, the heat isn't even the weirdest part. It’s the "pop-up" storms. On a typical July afternoon, the sun will be screaming, and then, around 3:00 PM, the sky turns black. You get a thirty-minute deluge that feels like a monsoon, and then—poof—it’s gone. The sun comes back out, and now the world is basically a giant sauna because all that rain is evaporating off the hot asphalt.
- Drink more water than you think you need.
- If you're doing yard work, do it before 8:00 AM or after 7:00 PM.
- Check your AC filters monthly; those units work overtime in Mississippi.
Is There Actually a Fall?
Locals often joke that we have two weeks of fall, and they usually happen on a random Tuesday in October.
While the calendar says September is autumn, the olive branch ms weather usually says otherwise. September is frequently one of the driest months, but it stays hot. We call it "False Fall" when we get that first cool breeze in mid-September, only for the temperature to spike back to 92°F three days later.
True relief usually arrives in mid-October. This is the best time of year in Olive Branch. The humidity finally breaks, the mosquitoes stop being so aggressive, and the nights get crisp. If you’re heading to a high school football game at Olive Branch High or Center Hill, you’ll actually need that light jacket. Average highs drop to the 70s in October and the 60s in November.

It’s the season of bonfire weather and outdoor festivals. The air feels thinner, cleaner. But keep an eye on the Gulf. Late summer and early fall are also hurricane season. While we are too far inland for the catastrophic winds of the coast, Olive Branch often catches the remnants of tropical systems. This usually means several days of "gray-out" rain and occasional gusty winds that can knock down limbs from our massive oak trees.
The Winter Wildcard: Ice Over Snow
Snow in Olive Branch is a rare, magical event that usually results in the entire city shutting down.
Seriously. If there is even a rumor of a snowflake in the olive branch ms weather forecast, the Kroger on Goodman Road will be cleared of milk and bread within two hours. It’s a regional tradition.
But the real threat in North Mississippi isn't snow—it's ice. Because we’re right on that line where freezing air meets moisture, we often get "wintry mixes." A quarter-inch of ice is way more dangerous than three inches of snow. It weighs down the power lines and turns Hwy 78 (I-22) into a skating rink.
- December: A coin flip. Sometimes it's 70°F on Christmas; sometimes it's 30°F.
- January: The coldest month. Lows average in the 30s, but we can see "Arctic plunges" that drop us into the single digits.
- February: The gloomiest month. It's gray, it's wet, and everyone is ready for spring.
What Most People Get Wrong About the Climate Here
One of the biggest misconceptions is that it's "always hot" because we're in Mississippi.
The reality is that our winters are surprisingly biting. It’s a "wet cold." That dampness in the air cuts right through a wool coat in a way that a dry cold in Colorado just doesn't. You'll see people from up north move here and laugh at us for wearing parkas in 40-degree weather, but three months later, they’re the ones shivering because that humidity makes the cold feel like it's settled into your bones.
Another thing? The wind. Because Olive Branch is relatively flat compared to the hills further south, the wind can really whip across the landscape, especially in the late fall and early spring.
Actionable Insights for Olive Branch Residents
Living with olive branch ms weather requires a bit of strategy. You can't just wing it.

First, invest in a high-quality "smart" thermostat. With the way temperatures swing 30 degrees in a single day, having a system that can automatically switch between heat and air (or at least be controlled from your phone) is a lifesaver.
Second, pay attention to your home's drainage. We get a lot of rain—roughly 54 inches a year. That’s significantly higher than the national average. Make sure your gutters are clear, especially before the spring rains hit, to avoid foundation issues which are common in our clay-heavy soil.
Third, get a "go-bag" for severe weather. It sounds dramatic until the sirens go off. Have your chargers, some water, a flashlight, and your important documents in a spot where you can grab them and get to an interior room or storm shelter in under sixty seconds.
Finally, enjoy the porch days. For all the drama of the storms and the intensity of the heat, there are those perfect Mississippi evenings where the temperature sits at 72°F, the cicadas are buzzing, and the sunset looks like a painting. Those are the moments that make the rest of the year's weather worth it.
To stay truly prepared, keep a close watch on the local radar rather than just the "percentage chance of rain" on your phone. In Olive Branch, a 20% chance of rain often means a 100% chance of a downpour on your specific house while your neighbor stays dry. It’s just how the Mid-South rolls.
Be sure to check your tire pressure when those first cold snaps hit in November. The sudden drop in temperature is notorious for triggering every "low tire" light in the city simultaneously. Also, if you’re planting a garden, wait until after April 15. We almost always get one "Easter snap" freeze that kills off the early tomatoes of anyone who got too impatient.
Basically, respect the weather here, and it’ll respect you. Keep your umbrella in the car, your flashlight charged, and your sense of humor intact. You're going to need all three.
