If you’re planning a trip to the Northwoods, you’ve probably looked at a map and figured Pembine is just "cold." Honestly, that’s a bit of an oversimplification. Sitting right on the edge of Marinette County, this little town deals with a climate that can be wildly unpredictable. One day you’re basking in a 75-degree breeze, and the next, you’re scraping a surprise layer of frost off your windshield in late May.
The weather in Pembine Wisconsin isn't just a backdrop for your vacation; it’s the main character. It dictates when the waterfalls are roaring, when the trails are passable, and whether you’ll need a heavy parka or just a light flannel.
The Reality of Pembine’s Seasons
Most people think of Wisconsin weather as a binary: either it’s summer or it’s a frozen tundra. But in Pembine, the transitions are where things get interesting.
The town falls under the Dfb Köppen Climate Classification, which basically means a humid continental climate with mild summers. You aren't going to get the sweltering, oppressive heat of the South here. Instead, July—the hottest month—usually tops out at an average high of 79.9°F. It’s comfortably warm. You can actually breathe.
Winter: The Long Haul
Winter doesn't just "visit" Pembine. It moves in and refuses to leave.
January is the statistical heart of the cold, with average lows dipping to 4.9°F. But averages are liars. It’s not uncommon to see the mercury plunge well below zero, especially when those Arctic blasts come screaming down from Canada.

Snow is a constant. We're talking an annual average of about 63 inches. While that’s not as intense as the "lake effect" snowbelts further north in Vilas or Iron County (which can see 100+ inches), it’s more than enough to keep the snowmobile trails in prime condition from December through March.
- January: The snowiest month, averaging 15.2 inches.
- February: Windy and biting. Average high is 28.4°F, but the wind chill makes it feel like 10°F.
- March: The "mud month" begins. You get a mix of 40-degree thaws and 10-inch "sneaky" snowstorms.
Spring: The Great Awakening (and the Bugs)
Spring in Pembine is... complicated.
The last frost usually doesn't happen until somewhere between May 11th and May 20th. If you plant your garden before Memorial Day, you’re basically a gambler.
April is the windiest month of the year, with gusts averaging 12 mph but frequently hitting much higher. It’s a messy time. The 55.6 inches of snow that accumulated over winter starts to melt, turning the ground into a sponge. This is also when the waterfalls in Marinette County, like Dave’s Falls just down the road, are at their absolute most violent and beautiful.
When Is the Weather in Pembine Wisconsin Actually Good?
"Good" is subjective. If you like ice fishing, January is your peak. But for most human beings, the "Comfortable Weather Window" starts in mid-May and runs through September.

According to climate data from Plantmaps and NASA'S MERRA-2 project, Pembine sees about 138 days of "comfortable" weather per year. That’s roughly 4.5 months where the humidity is low, the sun is out, and you won’t freeze your nose off.
The Summer Sweet Spot
July is the crown jewel. With nearly 15 hours of daylight in June and July, the days feel endless. The humidity stays around 68-70%, which is enough to feel like summer but not so much that you're wearing the air.
Interestingly, June is the wettest month, averaging nearly 4 inches of rain. These aren't usually day-long drizzles; they tend to be fast, heavy thunderstorms that roll through in the afternoon, leaving everything smelling like pine needles and damp earth.
The Autumn Gold
September is, quite frankly, underrated.
The average high is a crisp 69.9°F, and the humidity drops. It’s perfect hiking weather. The first frost usually hits between September 21st and September 30th, which triggers the famous Northwoods color change. By the second week of October, the maples and oaks are a riot of orange and red, but the air starts to get a real "teeth" to it.

Microclimates and Local Quirks
One thing many people don’t realize is how much the local geography affects the weather in Pembine Wisconsin.
Being inland, Pembine doesn't get the same "lake cooling" effect as cities right on Lake Michigan (like Marinette or Menominee).
This means Pembine can actually be 5 to 10 degrees warmer on a summer afternoon than the coast. Conversely, on clear winter nights, the lack of a nearby large body of water means the heat escapes into space rapidly. This results in "radiational cooling," where Pembine can be significantly colder at 3:00 AM than places just 30 miles East.
Practical Advice for Your Visit
If you are headed to Pembine, stop trusting your phone's default weather app a week in advance. It’s almost always wrong. Instead, look at the National Weather Service (Green Bay office) for the most accurate regional trends.
- Layers are a religion. Even in July, a 79-degree day can turn into a 50-degree night. Bring a hoodie.
- Bug season is real. Late May through June is "black fly" and mosquito season. If the weather is warm and damp, they will be out in force.
- Check the dew point. In the summer, if the dew point is under 60°F, it’s going to be a gorgeous day. If it hits 65°F or 70°F, prepare for some serious Wisconsin "mugginess."
- Winter driving. If you aren't used to driving in 60+ inches of annual snowfall, make sure your vehicle has decent tires. The backroads around Pembine aren't always cleared immediately after a 2:00 AM dusting.
Actionable Next Steps
To make the most of the weather during your trip, you should check the Marinette County Waterfall Map specifically after a period of heavy rain in June for the best views. If you're a snowmobiler, monitor the Wisconsin DNR Snow Conditions Map starting in late December; Pembine's trails often open earlier than those further south due to the higher elevation and colder average temperatures. For those planning a garden or a long-term stay, note that Pembine is now classified as USDA Plant Hardiness Zone 4b, meaning you should stick to plants that can survive -25°F winters.
