Honestly, if you’re heading toward Parke County, you probably have a mental image of quiet covered bridges and the smell of fried tenderloin. It’s a vibe. But let’s talk about the thing that actually dictates whether your weekend at Turkey Run is legendary or a literal washout: the Marshall Indiana weather.
People treat Midwestern weather like a monolith. They assume if it’s snowing in Indy, it’s snowing in Marshall. Not quite. Tucked away in that western pocket of the state, Marshall sits in a unique spot where the terrain starts to roll a bit more than the flat northern plains, and the wind—man, the wind—tells a different story.

Right now, as we sit in mid-January 2026, the town is currently shivering through a typical winter night. It's about 22°F outside, but with a 11 mph wind coming off the south, it actually feels closer to 10°F. If you’re planning to step out tonight, don’t let the "balmy" 20s fool you. The humidity is sitting at 48%, and the sky is just a flat, cloudy blanket. There's about a 10% chance of snow, which in Marshall usually means a light dusting that makes the gravel roads look like powdered sugar.
The 2025 Reality Check: Why We’re All a Bit Wary
You can’t talk about the weather here without mentioning the wild ride we had in 2025. Last year was... a lot.
We saw things move from record cold to a fairly terrifying spring. On March 15, 2025, a potent low-pressure system tore through the area. Most people remember it for the widespread power outages, but for those of us watching the radar, the tornado that touched down in Parke County was the real headline. It wasn't just a one-off, either. By April 2nd, a massive line of storms swept in after sunset, bringing winds between 60 and 80 mph.
It’s that "after sunset" part that gets you in a small town. When the sirens go off and it's pitch black, the Marshall Indiana weather stops being a conversation starter and starts being a survival plan.

Breaking Down the Seasons (The Stuff the Charts Miss)
Most "expert" guides will tell you the best time to visit is October. They aren't wrong, but they're missing the nuances.
Winter: The Long Chill
January is officially the coldest month in Marshall. We usually see highs around 35°F and lows dipping to 20°F, but 2026 has been throwing some curveballs. For instance, looking at the forecast for the next few days, we’re seeing a high of 38°F today (Friday, January 16) with snow showers likely. But then, look at Tuesday—the low is expected to hit a bone-chilling 7°F.
Snowfall averages about 3.7 inches in January, but it’s the "clipper" systems that really define our winters. These fast-moving storms can drop three inches of snow in two hours and then vanish, leaving the sun to glare off the white-out while the temperature stays in the single digits.

Spring: The Great Transition
Spring here is basically a giant wrestling match between Gulf moisture and Canadian cold. April is historically the windiest month, averaging about 17.4 mph. It’s breezy, sure, but it’s also when the flooding risk peaks. In early April 2025, some parts of central Indiana saw over 8 inches of rain in a week. The Big Blue River saw levels we haven't seen in decades. If you're planning on hiking the ravines at Turkey Run in April, check the river gauges first. Seriously.
Summer: The Muggy Reality
July is the hottest, with an average high of 85°F. But that doesn’t tell you about the "muggy days." By mid-July, we usually hit about 19.5 days a month that feel genuinely gross. The humidity in Marshall can hit 92% in the mornings before the sun starts baking the cornfields.
Autumn: The Golden Ticket
September is actually the clearest month. You get about 15 hours of sunshine a day and the humidity drops to its lowest point of the year—around 67%. This is the "Goldilocks" zone.
What to Pack: A Marshall Survival Guide
If you're coming to visit, don't be that person who brings a light windbreaker and thinks they're set.
- The "Three-Layer" Rule: In the spring and fall, you’ll start the day at 40°F and end it at 70°F. Wear a base layer, a flannel, and a vest.
- Boot Strategy: Marshall isn't all pavement. If it rained within the last 48 hours, the clay-heavy soil is going to be a muddy mess. Bring actual boots, not "fashion" sneakers.
- The Wind Factor: Because of the open fields surrounding the town, the wind chill is almost always 5-10 degrees lower than the actual temperature in the winter.
Actionable Advice for Your Trip
If you are tracking the Marshall Indiana weather for a visit this week, pay close attention to Saturday, January 17th. We’re looking at a high of only 22°F with 19 mph winds from the west. That’s a "stay inside and drink coffee" kind of day.
Before you head out, check the local Parke County scanner or the National Weather Service's Indianapolis feed. The weather here moves fast, and it’s always better to know if those clouds on the horizon are just "cloudy" or "take cover" cloudy. Honestly, just keep a sturdy pair of boots in the trunk and a weather app on your home screen, and you'll be fine.
