Trick-or-treaters across Whitemarsh, Plymouth and Whitpain townships can leave the heavy coats at home Saturday, Oct. 31.

The National Weather Service's Mt. Holly, New Jersey, branch is calling for mostly sunny skies and a high near 70 degrees on Halloween, with overnight lows dropping to about 52, Patch reported. Some areas could see lows in the mid-40s.

"Temperatures will also be warming with highs in the low to mid 70s by Friday," the agency said in a statement.

The warmest day of the week will be Friday, Oct. 30, with highs reaching 76. Halloween itself should bring mostly sunny skies during the day, with cloud cover potentially moving in around dusk. No rain is expected.

The mild forecast is a shift from Halloween 2024, which tied 1946 as the hottest on record in the Philadelphia area. Temperatures hit 82 degrees that year, according to the National Weather Service, with humid conditions.

Warmer daytime temperatures and sun on Saturday could favor lighter costumes for kids heading out in the afternoon.

Families looking for more to do over the weekend have several options close to home.
