What does the Old Farmers Almanac say about our Butte Fall Forecast?

Fall in Butte is expected to follow the broader Intermountain/High Plains pattern that the Old Farmers' Almanac outlines. September and October are likely to bring warmer-than-average temperatures but with below-normal precipitation—meaning more dry air than usual alongside extended warm stretches  Specifically, the Almanac notes that in the Intermountain region (which includes western Montana), September should average around 67 °F (about 3° warmer than normal) with roughly 0.5″ of rain, slightly below typical levels. October will be cooler—more like 52 °F—and remain fairly dry with only about 1″ of rainfall.

Looking at the Montana‑specific outlook, the longer‑range forecast confirms that fall in Butte should feel warm but dry, matching the broader pattern: warm early autumn followed by gradually cooling days toward late October, with precipitation tending to stay below seasonal norms.

What does this mean for locals in conversation? Imagine crisp days that stay comfortable into mid‑October, ideal for outdoor fall activities or foliage trips—though you’ll want to plan early if you’re after peak color because the extended warmth could delay leaf change. Expect very dry conditions increasing the risk of wildfire or extended dust spells, but less worry about muddy, rainy days.

By mid‑October we may begin to sense a real change—cooler nights, maybe the first frost or flurry, especially at elevation. And while snow is unlikely early on, early snow or frost in higher elevations of Montana is possible by early to mid‑October.

So, in Butte, anticipate a fall that starts feeling similar to a late summer and then gradually transitions into cooler, drier autumn. We will expect warm days, dry conditions, with the season shifting noticeably by late October as cooler air arrives and the chance of frost increases.

.In short: for Butte, your fall 2025 forecast from The Old Farmer’s Almanac leans warm and parched early, cooling off into a decidedly autumnal end—with drier skies than usual and potentially delayed fall colors.
