The Old Farmer’s Almanac Fall 2026 Forecast: What to Expect Across America

A Tale of Two Autumns

If you’ve been dreaming of cozy sweaters, pumpkin patches, and colorful leaf-peeping trips, there’s some interesting news for fall 2026. The Old Farmer’s Almanac has released its long-range forecast, and it predicts two very different autumns depending on where you live.

Important Point: The Almanac predicts cooler-than-average temperatures across the eastern United States and along the Pacific Coast, but summer-like warmth could stretch well into September and October for much of the nation’s interior.

How Reliable Is This Forecast?

Before you plan your entire fall wardrobe, here’s what you should know:

• 80% accuracy rate – The Almanac claims this success rate for its predictions
• Three science sources – They use solar science, climatology (study of climate), and meteorology (study of weather)
• Still a prediction – Long-range forecasts aren’t as reliable as tomorrow’s weather report
• Conditions can change – Meteorologists caution that forecasts months in advance can shift significantly

Take With a Grain of Salt: While this is a fun annual tradition, treat it as a general guide rather than a guarantee.

Regional Breakdown: What’s Coming Your Way

Northeast

• Temperatures: Below average (cooler than normal)
• Rainfall: More than usual – damp start to fall

Atlantic Corridor (Major East Coast Cities)

• Temperatures: About 1°F cooler than normal
• Rainfall: Drier overall

Appalachians & Southeast

• Temperatures: Cooler than average
• Rainfall: Below normal across most of the region
• Northern Florida: Cooler and drier
• Southern Florida: Cooler but slightly wetter than average

Midwest

• Upper Midwest: Cool September, slightly warmer October
• Heartland: Warmer in northern areas, slightly cooler farther south
• October: Could become noticeably wetter in parts

Texas & Oklahoma

• Northern Areas: Slightly cooler with significantly more rain (up to 4 inches above normal!)
• Southern Texas: Warmer than average

High Plains

• Temperatures: Warmer than normal
• Rainfall: Drier than normal throughout the season

Pacific Northwest

• Temperatures: Cooler than average
• Rainfall: One of the wettest forecasts – September could bring 3 extra inches of rain

Pacific Southwest (California)

• September: Near seasonal temperatures
• October: Slightly cooler
• Northern areas: A bit more rain than usual
• Southern areas: Drier

Desert Southwest

• September: Warmer than average
• October: Cooling slightly
• Rainfall: Below average all season

Beyond the Lower 48 States

Alaska

Hawaii

• Temperatures: Cooler than average for both September and October
• Rainfall: Eastern islands could get up to 4 extra inches of rain
• Watch out: Possible tropical storm in mid-September

What This Means for Your Fall Plans

If You Love Classic Fall Weather (Cool & Crisp):

Head to: Northeast, East Coast cities, Appalachians, Southeast, Pacific Northwest, Northern Alaska, Hawaii

If You Want Extended Summer Warmth:

Head to: Northern Plains, Heartland, Deep South, High Plains, Southern Texas, Desert Southwest, Southern Alaska

For Leaf Peeping:

• Cooler regions = potentially earlier, more vibrant color changes
• Warmer regions = delayed peak foliage
• Check the Almanac’s fall foliage map for peak timing predictions

For Outdoor Activities:

• Pacific Northwest: Pack serious rain gear!
• Northern Texas/Oklahoma: Prepare for very wet conditions
• High Plains/Desert Southwest: Great for hiking – dry and warm
• Hawaii: Monitor tropical storm updates for mid-September

Summary

The Old Farmer’s Almanac’s fall 2026 forecast paints a picture of a split nation: the coasts and eastern regions get a classic cool, crisp autumn, while the vast interior enjoys extended summer warmth. Rainfall follows a similar pattern – wet on the coasts (especially Pacific Northwest), dry in the middle.

Remember: this is a long-range forecast with inherent uncertainty. The 80% accuracy rate is impressive, but weather loves to surprise us. Use this as a helpful planning guide, but stay flexible and check local forecasts as your dates approach.

Whether you’re reaching for sweaters early in Maine or still wearing shorts in Texas come October, fall 2026 promises to be an interesting season across America!

Frequently Asked Questions

How does The Old Farmer’s Almanac make these predictions?

They use a secret formula developed in 1792 that combines three scientific disciplines: solar science (sunspot activity), climatology (historical weather patterns), and meteorology (current atmospheric conditions). The exact formula is kept in a black box at their headquarters!

Should I book my fall vacation based on this forecast?

Use it as a general guide, not a guarantee. Long-range forecasts (months out) are much less accurate than 7-10 day forecasts. Book flexible accommodations and check updated forecasts 1-2 weeks before your trip.

What does "cooler/warmer than average" actually mean?

It compares predicted temperatures to 30-year historical averages for each region. "1 degree cooler than normal" means if the average September high is 75°F, they’re predicting around 74°F. These are regional averages – individual days will vary!

Why is the Pacific Northwest so wet in this forecast?

The Almanac’s models suggest a persistent storm track aiming at the region this fall. This could mean more rainy days, not necessarily heavier individual storms. Great for waterfalls and moss, challenging for outdoor dining!

When will we know if this forecast was accurate?

By late November 2026. Meteorologists will compare actual September-November temperatures and precipitation against the predictions. The Almanac publishes a "report card" each year showing how they did.
