Here’s why “sweater weather” actually matters

Look no further than the 8 million #sweaterweather posts on Instagram or the staggering 239.6 million posts on TikTok. “Sweater weather” is more than just a seasonal change; it’s a cultural phenomenon that rivals the PSL for fall fame.

Social proof, combined with recent survey data, suggests that most industries offering seasonal products could benefit by timing their campaigns based on actual weather rather than a calendar date. When asked what prompts them to make fall-related changes, consumers overwhelmingly cited weather — 65% mentioned how it feels, and 64% noted the actual forecast¹. This means that understanding subtle weather shifts presents a major opportunity to tap into seasonal consumer habits.

In other words, to truly connect with your audience, you need to know precisely when they’ll be pulling out their sweaters — or even buying new seasonal products.

The relativity of weather

Pinpointing when sweater weather starts in specific markets requires more than just knowing when temperatures will dip below a certain point. Weather is a relative experience. What consumers qualify as sweater weather can span a 10 degree difference depending on where they live. For example, when it’s 45°F in Minneapolis, people are out in shorts, enjoying the brisk air. But when it’s 45°F in Georgia, people are bundled up on the couch, texting friends to make sure they’re staying warm.

We asked consumers what temperature makes them reach for their sweaters. The results? They provide a guide to when people across U.S. regions will start feeling like it’s fall.

Median temps at which The Weather Channel users say fall weather becomes cool enough to put on a sweater are highest in the West at 60 degrees and lowest in the Upper Midwest at 50 degrees.

Here’s the thing about fall weather: More than any other season, people anticipate sweater weather, and when it arrives, they’re ready to make changes.

But there’s one statistic that underscores why marketers should engage with consumers at the first hint of sweater weather: 66% of people say fall weather makes them want to try something new. For Gen Z, that number jumps to 79%¹.

The power of relativity

Brands across industries should take note: If the majority of consumers base their fall-related behavior on the feeling of autumn, knowing exactly when those feelings will arise is crucial.
