Baltimore Weather Service Forecasts Dry, Mild Halloween for Costumes

Families in Baltimore can expect dry conditions and mild temperatures for trick-or-treating on Saturday, October 31. The National Weather Service forecast issued Wednesday morning projects a high near 66 degrees for downtown Baltimore, followed by a low around 49 degrees at night. The chance of precipitation during typical trick-or-treat hours stands at 0 percent, and winds are expected to remain nearly calm.

This mild evening follows an unusually warm stretch in the region. Highs reached 75 degrees on Friday under sunny skies, a period the Sterling, Virginia, weather office described as 8 to 15 degrees above normal for late October. A dry front crossing the area Friday night brings cooler air, dropping lows into the upper 30s and 40s. This shift sets the stage for Saturday’s seasonable highs in the 60s.

Residents should note that Saturday is the final evening of daylight saving time. Clocks fall back one hour at 2 a.m. on Sunday, November 1. Sunset in Baltimore occurs at approximately 6:06 p.m. on Saturday, with civil twilight ending near 6:34 p.m. Most trick-or-treating will therefore take place after dark. The next evening’s sunset moves earlier to about 5:05 p.m., increasing the darkness for drivers and pedestrians.

Maryland transportation officials issued a safety reminder this week regarding the change in light. The Maryland Highway Safety Office reported 2,704 pedestrian-related crashes in Maryland in 2025, resulting in 101 deaths and 2,399 injuries. This figure represents a 7 percent decrease from the previous year. Transportation Secretary Katie Thompson noted that research indicates fatal crashes involving pedestrians and bicyclists can rise by up to 13 percent in the weeks following the fall time change.

State officials advise drivers to slow down during evening hours and check that all vehicle lights function properly. Pedestrians are encouraged to wear bright or reflective clothing and cross streets where lighting is available. The dry forecast may lead to higher numbers of people on sidewalks and in rowhouse neighborhoods between 5 and 9 p.m., making caution essential on residential streets.

Forecasters continue to monitor a low-pressure system forming over the Midwest. Current models suggest this system will move east late in the weekend, with rain chances holding off until Sunday evening. Baltimore shows a 21 percent chance of showers Sunday night, with highs in the upper 60s. The weather service updates the local forecast several times daily at weather.gov/lwx.

The National Weather Service point forecast for downtown Baltimore lists a mostly sunny Saturday followed by a mostly cloudy night. The current outlook suggests comfortable conditions for outdoor activities, though a jacket may be necessary for children staying out past 8 p.m. as temperatures drop into the 50s.
