If you've been clutching your favorite oversized cardigan since late August, waiting for the humidity to break, you’re not alone. We've all been there. Staring at the thermometer in mid-September while it mocks us with 85-degree readings. It's frustrating. Honestly, the question of when is fall weather coming 2024 has turned into a bit of a national obsession because, for many of us, the "crisp air" was MIA for a long time.
Summer didn't just linger this year; it dug its heels in like a stubborn toddler.
The Short Answer: It’s Complicated (and Late)
Basically, meteorological fall starts on September 1. That's the date scientists use to keep their data clean. But Mother Nature doesn't look at a calendar. For 2024, the "feel" of fall—that specific moment when you can finally turn off the AC without waking up in a sweat—was delayed by a massive ridge of high pressure that sat over the central and eastern U.S. for weeks.
NOAA (the National Oceanic and Atmospheric Administration) recently confirmed what our electric bills already told us. Fall 2024 officially ranked as the warmest on record for the contiguous United States. We’re talking about data going back 130 years.

It wasn't just a "little bit" warm. The average temperature for the lower 48 states from September through November was $57.6^{\circ}\text{F}$. That's $4.1^{\circ}\text{F}$ above the 20th-century average. If that doesn't sound like much, in climate terms, it’s a massive spike.
Why the Heat Stuck Around
A few things collided to keep us in shorts way past Labor Day:
- The La Niña Waiting Game: We spent much of the year in a "La Niña Watch." While La Niña usually brings cooler, wetter conditions to the North, it took its sweet time developing.
- Persistent High Pressure: A "heat dome" basically parked itself over the midsection of the country. It blocked the Canadian cold fronts that usually slide down and give us that first taste of frost.
- Ocean Temperatures: The "bath water" temperatures in the North Atlantic and Pacific were significantly higher than normal, which kept coastal air much milder than usual.
When Did the Chill Finally Hit Your Zip Code?
When we talk about when is fall weather coming 2024, the answer depends entirely on where you're standing. The experience in Maine was a world away from the experience in Southern California.
The Northeast and Mid-Atlantic
You guys had it weird. September was actually quite dry and pleasant in spots, but the true "chill" didn't arrive with any consistency until late October. States like New Jersey and Delaware actually saw their driest falls on record. I remember seeing photos of Brooklyn in mid-November where the leaves were shriveled and brown before they even had a chance to turn those brilliant reds and oranges. The heat just cooked them.
The Midwest and Great Plains
This region saw the "double whiplash." It was sweltering through September and most of October. Then, seemingly overnight in early November, the door to the Arctic flew open. Minnesota and Nebraska recorded their warmest falls ever, yet they still had to deal with sudden, sharp drops that sent everyone scrambling for their heavy coats.
The South and Gulf Coast
Honestly, "fall" is a strong word for what happened here. With five hurricanes making landfall in the U.S. this season—including the devastating Helene and Milton—the weather was more "tropical chaos" than "pumpkin spice." True cool air didn't really settle into places like Alabama or Mississippi until well into November. Alabama actually recorded its warmest November on record.

The West Coast
California and the Southwest were stuck in a loop. In October, Phoenix and Las Vegas were still shattering daily heat records. While some higher elevations in the Pacific Northwest got an early dusting of snow, the valleys stayed stubbornly balmy. It took a massive "bomb cyclone" in late November to finally kick the door down and bring the rain and chill that signifies the end of the dry season.
The Foliage Fiasco of 2024
One of the biggest casualties of the late-arriving fall weather was the leaf-peeping season. It was... well, "muted" is a nice way to put it.
The Old Farmer's Almanac had predicted a "steamy" season, and they weren't wrong. For the best fall colors, you need warm, sunny days and cool, crisp nights (but not freezing). Because those nights stayed warm, the chlorophyll didn't break down as quickly. In many areas, the leaves just stayed green until a hard frost hit, at which point they turned brown and fell off in a single weekend.
If you went to the White Mountains or the Blue Ridge Parkway in early October expecting a technicolor dreamscape, you probably saw a lot of thirsty-looking green trees.
Real Data: The Records We Broke
It's easy to say "it felt hot," but the numbers from the National Centers for Environmental Information (NCEI) are staggering.
- Warmest Falls on Record: Maine, Minnesota, Nebraska, Texas, and Wisconsin.
- Driest Falls on Record: Connecticut, Delaware, New Jersey, and Maine.
- The "October Surprise": In October 2024 alone, Utah, Arizona, New Mexico, and Texas all had their warmest October in history.
What This Means for Your Winter
Usually, a late fall means a shorter transition into winter. We saw that happen in the Central Plains. One week it was 75 degrees; the next, Oklahoma was getting hammered with heavy rain and flooding that felt much more like a winter storm pattern.
The "La Niña" that was supposed to arrive in the summer finally started showing its face in October and November. This typically means the Pacific Northwest stays wet and the South stays dry and warm. If you're wondering if you missed fall entirely, you kind of did. In many states, we skipped the "light jacket" phase and went straight from "sweating in a T-shirt" to "scraping ice off the windshield."
Actionable Steps for the Remainder of the Season
Since the weather has been so unpredictable, you can't rely on the old "wait until November 1 to winterize" rule. Here is what you should actually do now:
- Check Your Tree Stress: Because of the record dryness in the Northeast and the heat in the West, trees are stressed. If you have large limbs overhanging your house, get them inspected. Stressed trees are much more likely to snap during the first heavy snow or wind storm.
- Adjust Your Skin Routine: The sudden jump from humid summer air to dry, indoor heating is a wrecking ball for your skin. Swap the light lotions for something with ceramides sooner than you normally would.
- Don't Trust the "Average" First Frost: In 2024, those dates were pushed back by 10 to 14 days in many regions. If you're a gardener, keep your frost blankets ready even if the forecast looks "fine"—the temperature drops are happening faster and deeper once they finally arrive.
- Seal the Gaps: Since we didn't get a gradual cooling, you might not have noticed drafts. Take a candle around your windows on a windy night; if the flame flickers, you're losing heat.
Fall 2024 was a reminder that the "traditional" seasons are becoming a bit of a myth. We're living in a time of "seasonal creep," where summer is expanding its territory. While we eventually got our sweater weather, it took a record-breaking effort from the atmosphere to make it happen.

If you finally have a frost on your pumpkin, enjoy it. It was a long, hot road to get here.
Next Steps for Your Home:
- Check your local NWS (National Weather Service) office for your specific "Freeze Warning" history to see how much 2024 deviated from your local norm.
- Drain your outdoor spigots now; the late heat often makes us forget that a deep freeze can happen overnight without the usual weeks of cooling.
