Chicago, IL – Halloween weekend across the Chicago area could begin with light rain before conditions improve for trick or treaters Saturday, October 31. Families can also expect seasonably mild temperatures and an extra hour of sleep as daylight saving time ends early Sunday, November 1.
According to the National Weather Service in Chicago, periods of mainly light showers will develop Friday night and continue into Saturday morning. Rain coverage is expected to diminish by peak Halloween trick or treating hours, although occasional sprinkles or drizzle could linger in isolated locations.
What to Expect Halloween Evening
Between approximately 1 p.m. and 8 p.m. Saturday, temperatures should range from the 50s to around 60 degrees after sunset. East southeast winds of 5 to 15 mph are expected.
Forecasters do not anticipate heavy downpours, meaning outdoor Halloween activities are unlikely to experience significant weather disruptions.
Saturday afternoon temperatures could reach 57 to 67 degrees across the region, with the greatest shower coverage expected during the morning.
Clocks Fall Back Sunday as November Begins
Daylight saving time officially ends at 2 a.m. Sunday, November 1, when clocks move backward one hour to 1 a.m.
Sunday's forecast calls for partly cloudy conditions and highs between 62 and 69 degrees, providing a relatively mild start to November.
Monday, November 2, could be even warmer, with highs reaching 63 to 70 degrees. Another chance of afternoon showers is possible, particularly across northern and western portions of the forecast area.
Families planning Halloween activities should keep a light rain jacket handy, but the latest outlook suggests widespread cancellations due to weather are unlikely.
