Halloween nights in the Seattle area aren't as chilly on average as they were a few decades ago, a new report finds.

What they found: From 1970 to 2023, the average low temperatures recorded at Seattle-Tacoma International Airport in October rose 2.5°F, per an analysis from Climate Central.

That's on par with the average level of warming seen nationwide during that time frame, the nonprofit says.

Yes, but: When I did a test run of my kid's costume outside on Sunday, he was still freezing, despite the woolen thermal underwear he was wearing underneath.

So, Seattle parents, you may still need to problem-solve how to make your kid's skeleton (or Spider-Man or mermaid) costume warmer.

What's next: The National Weather Service is predicting Seattle's weather this Halloween will be rainy with a low of 42°F.

Flashback: Low temperatures in the Seattle area on Halloween have ranged from a record low of 30°F in 2006 to 71°F in 1949, Climate Central reports.
