Ghosts and goblins may need a coat or a jacket for trick-or-treating Saturday night, but at least the umbrella can stay at home.

The weather forecast for Halloween night calls for temperatures in the upper to mid-40s from 6 p.m. to 8 p.m., said Justin Gesling, St. Joe Now meteorologist. Temperatures later in the evening will dip to about 38, he said.

The good news, he said, is that the winds will be calm and there is no rain in the forecast.

“It is going to be clear,” Mr. Gesling said. “An extra layer for the costumes is going to work well.”
