From Soaked Streets to Clear Skies: A Region-by-Region Look at Halloween Weather Across the United States

A Mixed Bag of Weather for Halloween Night

As October draws to a close, Halloween festivities across the United States will unfold under wildly different skies. Some trick-or-treaters will face chilly winds and rain, while others can expect a mild, calm evening perfect for costumes and candy.

Forecasters describe the setup as a classic late-October split: wet and windy in the Northeast, unsettled across the Pacific Northwest, but relatively calm and mild through the Central Plains and Southeast.

Northeast: A Damp and Blustery Night

A storm system pushing out of the Tennessee Valley is expected to bring steady rain and gusty winds to the Northeast and Mid-Atlantic late in the week. The timing of the storm could determine whether parades and neighborhood events stay dry or get drenched.

Cities from Philadelphia, PA, to New York City, NY, and Boston, MA, will see temperatures in the 50s to low 60s Fahrenheit during the afternoon, but as night falls, wind and moisture will drive AccuWeather RealFeel® values into the 30s and 40s.

By Friday, the chill will deepen as winds strengthen behind the departing system.
“Parents and children still planning to head outdoors may need an extra layer or two," advised AccuWeather Senior Meteorologist Bob Larson.

Higher elevations near the White and Green Mountains may even experience a touch of icy precipitation after sunset, while the Great Lakes could see lake-effect rain under cold northwesterly winds.

Pacific Northwest: Wet, Windy, and Wild

Those celebrating along the Pacific Coast will have little luck dodging raindrops. A new storm system will come ashore by Halloween, bringing periods of heavy rain and gusty winds from Seattle, WA, to Portland, OR.

“Anyone dressing up as a sweet treat may feel like they’re melting," joked one forecaster, warning that umbrellas and rain gear will be essential accessories. Winds along the coast could gust up to 25 mph, but should ease inland by late evening.

The rain may persist into the weekend before drier intervals return.

Central and Western U.S.: Mostly Tranquil

Across the Great Plains and Midwest, Halloween should be largely quiet. From Nebraska down through Texas, dry skies are expected through Friday, with temperatures in the 40s and 50s after sundown.

In the Dakotas and Minnesota, a few scattered showers could drift through, but most areas will stay dry. The western Great Lakes may see cloudy skies and a few drops of rain, while farther south, the evening will be chilly but calm.

By midnight, thermometers will hover near freezing in the Dakotas, dipping into the 30s across much of the Midwest. The advice is simple: “Pack an extra layer for your little monster."

Southern U.S.: A Calm and Pleasant Evening

The Southern Plains, Tennessee Valley, and Gulf Coast are expected to enjoy some of the best Halloween weather in the country. Clear skies, mild breezes, and evening temperatures in the 50s and 60s will make for a perfect night outdoors.

Forecasters note that while a few phantom clouds may drift overhead, no rain or wind from Hurricane Melissa will reach the Southeast. The only chill in the air will be from ghost stories, not the weather.

The Bottom Line

From drenched doorsteps in the Northeast to calm, moonlit skies in the South, this year’s Halloween forecast depends entirely on geography. Those in the Pacific Northwest will need umbrellas. The Northeast should prepare for gusts and cold rain. But for much of the Central and Southern U.S., costumes can shine without fear of soaking or shivering.

The weather may not cooperate everywhere, but the candy haul waits for no one.
