As Halloween approaches, families are finalizing costumes and preparing for trick-or-treat festivities. But this year, the weather forecast across the U.S. is painting a mixed and unusual picture for those celebrating on October 31. From summer-like warmth in the East to potential showers in parts of the South and Midwest, here’s what Halloween revelers can expect.
Warm Weather Surprises Trick-or-Treaters
In an unusual twist, much of the eastern U.S. will feel more like late summer than autumn. Cities from Texas up through the Northeast are anticipating temperatures far above the seasonal average. Forecast models show highs in the 70s to even low 80s in places like New York City, Boston, and Philadelphia, where costumes often need a few layers to keep warm on chilly Halloween nights. For those venturing out after sunset, the warmth should linger, with nighttime temperatures in the Northeast hovering around 70°F.
The Southeast will also be on the warmer side. From Washington, D.C., to Raleigh, families might consider lighter costumes or even trick-or-treating in shorts. Cities along the Gulf Coast, including Houston, could see daytime highs reaching the 80s, with minimal cooling during the evening.
However, the story is different across the Midwest and Upper Midwest, where cooler temperatures are expected. A cold front will sweep through the region, bringing showers and chilly winds to cities like Chicago and Detroit. Those farther west, like St. Louis and Cincinnati, may still enjoy the warmth, but areas closer to the frontal boundary will need a light jacket to stay comfortable.
Showers Threaten Halloween Festivities in Some Areas
While warm weather may be a treat for some, rain showers are expected to spook a few regions just as the trick-or-treaters come out. In central Ohio, including Columbus, there’s an 80% chance of rain starting Thursday afternoon, with the showers continuing into the night. This might mean that children in Columbus will want to consider weather-friendly costumes like Georgie’s famous yellow raincoat from It to stay dry.
Houston could also see some wet weather, although forecasters are cautiously optimistic. According to the National Weather Service, rain is likely earlier in the day, but meteorologists predict drier conditions by evening. Nonetheless, families in Houston are encouraged to be cautious as brief showers could still pass through, and parents are reminded to keep kids safe with reflective gear and flashlights.
In the Northwest, a storm moving in from the Pacific will bring cooler, damp weather to places like Seattle and Portland. Trick-or-treaters there might encounter hit-or-miss raindrops and will need extra layers, as temperatures are expected to fall into the 40s by nightfall.
A Historically Warm and Dry October
This Halloween caps off what has been an unusually warm and dry October for most of the country. Weather data shows that record high temperatures were set from Texas to Maine, with numerous cities in the Northeast, Midwest, and Plains reporting some of their warmest Octobers on record. Drought conditions have also spread, affecting up to 80% of the nation. The ongoing dry spell has raised wildfire concerns as far north as Connecticut and Massachusetts, impacting some classic Halloween traditions like bonfires.
Halloween Safety Tips for Families
As excitement builds for Halloween night, safety remains a top priority. Health experts and safety officials are reminding parents to equip kids with flashlights or glow sticks for visibility and to use reflective tape on costumes to make sure drivers can see them. Also, homeowners can do their part by keeping their porch lights on and clearing any obstacles along walkways.
Pet owners should take extra care as well, as doorbell-ringing trick-or-treaters can sometimes stress out pets, leading to accidental injuries or even bites.
And while the warm weather may change the usual Halloween feel, candy lovers needn’t worry: Americans are expected to buy around $6.5 billion worth of Halloween treats this year, according to the National Confectioners Association. Popular candies like M&M’s, Reese’s Cups, Sour Patch Kids, and Skittles are expected to fly off the shelves as trick-or-treaters—and some early tasters—stock up for the holiday.
A Halloween to Remember
Whether facing spooky showers or unexpected warmth, this Halloween promises to be memorable. While some may be tricked by the weather, there’s no shortage of treats in store for Halloween lovers across the country. As families head out to celebrate, staying prepared for the weather, staying visible, and staying safe will make this Halloween one to remember.
