Old Farmer’s Almanac Prediction for Wisconsin Fall 2026 Weather
The Old Farmer’s Almanac fall 2026 forecast is calling for a changeable autumn in Wisconsin: a cooler-than-average September followed by a slightly warmer and wetter-than-average October.
That is a notable change from the cool, dry conditions predicted for Wisconsin in fall 2025.
Wisconsin Fall 2026 Forecast at a Glance
According to the Old Farmer’s Almanac forecast for the Upper Midwest:
September: Cooler than average with slightly above-average rainfall
October: Slightly warmer than average with above-average rainfall
Overall pattern: A cool beginning to fall followed by a milder, wetter October
Best advice: Plan outdoor activities with flexibility and keep rain gear handy
Wisconsin is included in the Almanac’s Upper Midwest region, so these predictions cover a large geographic area rather than individual cities or counties. Actual conditions may vary considerably between Milwaukee, Madison, Green Bay and northern Wisconsin.
September 2026: A Cooler Start to Fall
The Old Farmer’s Almanac expects September to run cooler than average across the Upper Midwest, with rainfall finishing slightly above normal.
What Wisconsin Families May Notice
Cooler mornings arriving earlier in the month
More days that feel like fall rather than an extension of summer
Periods of rain interrupting otherwise comfortable outdoor weather
Faster temperature changes between afternoon and evening
An earlier need for sweatshirts and jackets at outdoor events
September is one of Wisconsin’s best months for outdoor adventures. The humidity usually begins to ease, mosquitoes become less troublesome and the state’s first fall colors begin appearing in the north.
It is also the beginning of apple season. Our Milwaukee-area apple-picking guide includes orchards, family activities and practical tips for planning a fall farm visit.
September Planning Tips
Bring an extra layer for evening festivals and football games.
Check orchard conditions before traveling, especially following heavy rain.
Wear waterproof shoes for farms, trails and corn mazes.
Watch for the first fall colors in northern Wisconsin beginning in September.
Keep a backup date available for weather-dependent activities.
Hikers can also explore the Ice Age Trail, which is especially beautiful as fall colors begin spreading south through Wisconsin.
October 2026: Milder but Wetter
October is expected to turn slightly warmer than average, according to the Almanac, but it may also be wetter than usual.
That does not necessarily mean warm weather every day. October can still deliver frost, strong cold fronts and even occasional snow in northern Wisconsin. A “warmer-than-average” month simply means the average temperature over the entire month is expected to finish above the historical norm.
What to Expect
Mild stretches between passing weather systems
More rainy days or periods of unsettled weather
Comfortable temperatures for outdoor activities when conditions are dry
Variable foliage timing depending on temperature, moisture and wind
Increasing chances of frost as the month progresses
Families planning pumpkin farms, corn mazes or festivals should pay particular attention to short-range forecasts. Wet fields can affect hayrides, parking areas and farm attractions even after the rain has stopped.

What Could the Forecast Mean for Wisconsin Fall Colors?
Weather plays an important role in both the timing and intensity of fall foliage.
The most vibrant colors generally develop when trees experience:
Plenty of sunlight
Cool—but not freezing—nights
Adequate soil moisture
Limited wind and severe weather
A gradual transition from summer to fall
A cooler September could help begin the seasonal transition, while a mild October might allow leaves to remain on some trees longer. However, extended rain, cloud cover or strong winds could mute colors or bring leaves down early.
Because Wisconsin’s fall color season progresses from north to south, there is no single statewide peak date. Northern Wisconsin can begin showing significant color in September, while southeastern Wisconsin frequently peaks during October.
Follow our Milwaukee-area fall color report and the official Travel Wisconsin Fall Color Report as your trip approaches. Those reports are far more useful for choosing a specific weekend than a forecast issued months in advance.

Regional Differences Across Wisconsin
The Almanac forecast covers the entire Upper Midwest, but fall weather varies substantially across Wisconsin.
Northern Wisconsin
Northern Wisconsin typically sees the state’s earliest frost and fall color. Even during a warmer-than-average October, freezing temperatures and occasional early snow remain possible.
Travelers should prepare for:
Rapid temperature drops after sunset
Earlier peak foliage
Frost and freeze advisories
Muddy trails following rain
Occasional wintry weather late in the season
Central Wisconsin
Central Wisconsin often provides a transition between the earlier Northwoods season and the later colors of southern Wisconsin.
Expect:
Cool September mornings
Peak color generally arriving after northern Wisconsin
Variable harvest conditions
Comfortable hiking weather between rain systems
Southern Wisconsin and Milwaukee
Southern Wisconsin usually enjoys the state’s longest stretch of fall weather. Lake Michigan can also influence temperatures near Milwaukee, keeping shoreline communities cooler on some days and milder on others.
A slightly warmer October could extend opportunities for:
Pumpkin picking
Hiking and biking
Outdoor dining
Football games
Community festivals
Halloween activities
For a particularly scenic fall outing, consider our guide to Holy Hill, one of southeastern Wisconsin’s most popular fall-color destinations.
What the Forecast Means for Apple and Pumpkin Farms
A cooler, somewhat wetter September could produce mixed conditions for Wisconsin farms. Adequate rainfall can benefit trees and late-season crops, but repeated wet weather can make fields muddy and complicate harvesting.
A wetter October could affect:
Pumpkin patch parking
Hayrides and wagon rides
Corn maze trail conditions
Weekend festival attendance
Harvest timing
Outdoor farm attractions
Always check a farm’s website or social media page before leaving home. Many farms adjust hours following heavy rain, and some stop admission early when parking lots or fields become saturated.
Hiking and Camping Outlook
Cooler September weather could provide excellent hiking conditions, especially when trails are dry. October may offer mild temperatures but a greater chance of wet or muddy terrain.
Before heading out:
Bring waterproof shoes or hiking boots
Pack layers and a rain jacket
Confirm campground closing dates
Avoid trails during thunderstorms or high-wind advisories
Wear blaze orange when hiking during hunting seasons

Agriculture and Gardening Considerations
Seasonal forecasts cannot predict the exact date of the first frost, but gardeners and farmers should still prepare for Wisconsin’s usual fall temperature swings.
For Gardeners
Monitor local frost and freeze alerts rather than relying on statewide averages.
Harvest tender vegetables before freezing temperatures arrive.
Keep plant covers readily available.
Plant spring bulbs once soil temperatures cool.
Complete lawn and garden cleanup during dry periods.
Avoid working in saturated soil, which can cause compaction.
For Farmers
A wetter October could reduce the number of suitable fieldwork days.
Crop moisture levels may vary depending on the timing of rainfall.
Cooler September conditions could influence crop maturation.
Local soil conditions will be more important than the regional seasonal outlook.
The Wisconsin State Climatology Office provides more detailed information about statewide temperature, rainfall and drought conditions.
How Does the NOAA Outlook Compare?
The NOAA Climate Prediction Center also publishes seasonal temperature and precipitation outlooks. These official outlooks are updated monthly and express the probability of conditions finishing above, near or below normal.
NOAA’s outlooks and the Old Farmer’s Almanac should not be interpreted in exactly the same way:
The Old Farmer’s Almanac publishes broad regional predictions written in everyday language.
NOAA uses probability maps developed from climate models, long-term trends, atmospheric patterns and ocean conditions.
Neither source can reliably forecast the weather on a particular festival weekend months in advance.
Check NOAA’s outlook again in August and September, when updated information will be available for more of the fall season.
How Accurate Is the Old Farmer’s Almanac?
The Old Farmer’s Almanac says its long-range forecasts are traditionally about 80% accurate, based on its own evaluation. That figure should be identified as the publication’s claim rather than a universally accepted independent measurement.
Independent reviews of almanac-style forecasts have often found considerably lower accuracy. Long-range forecasts also become less useful when applied to a particular city, weekend or outdoor event.
The Almanac says it combines:
Solar science
Climatology
Meteorology
Historical weather patterns
Long-term atmospheric and ocean trends
Its forecasts can be entertaining and useful for identifying a possible seasonal pattern, but they should not replace forecasts from the National Weather Service when making safety-sensitive or date-specific plans.
It is also worth noting that The Old Farmer’s Almanac and Farmers’ Almanac are separate publications with different histories and forecasting methods. This article focuses on the Old Farmer’s Almanac, which has been published since 1792.

Bottom Line: What Will Fall 2026 Be Like in Wisconsin?
The Old Farmer’s Almanac predicts that Wisconsin will experience a cooler-than-average September followed by a slightly warmer and wetter-than-average October.
That could mean a comfortable start to apple-picking and hiking season, followed by a mild but potentially soggy peak-foliage and pumpkin-farm season.
The most important takeaway is flexibility. Seasonal forecasts describe broad trends, not the weather on a particular day. Use the Almanac for an early look at the season, but rely on updated local forecasts when deciding whether to head to a festival, orchard, pumpkin farm or hiking trail.
