Chicago, Illinois — Families preparing for Halloween celebrations across the Chicago area may encounter a few light showers and sprinkles on Saturday, October 31, but the latest forecast suggests that rain is unlikely to completely disrupt trick-or-treating plans.
Clouds are expected to stick around through much of Halloween, with temperatures remaining relatively cool. However, a large portion of the region should turn dry by the evening, offering a reasonable window for families heading out to collect candy.
Temperatures are expected to remain in the middle to upper 50s during the evening, while winds should stay fairly light.
Chicago Halloween Weather Forecast: What to Expect Saturday
Halloween weather in Chicago is expected to feature stubborn cloud cover and occasional pockets of light rain.
Daytime temperatures will struggle to reach the 60s across much of the region. However, communities along and south of Interstate 80 have a better chance of reaching the lower 60s.
Scattered light showers could develop at different times throughout the day, although rainfall is not expected to be widespread.
The better opportunity for showers appears to be from the morning through the middle of the afternoon. Conditions could gradually become drier as Halloween evening approaches.
For families planning outdoor activities, the timing of the showers will be particularly important. Even brief periods of rain could make costumes, decorations and outdoor celebrations slightly less comfortable.
Will It Rain During Chicago Trick-or-Treating Hours?
The main question for families is whether rain will interfere with the traditional Halloween candy hunt.
The forecast indicates that the period between 4 p.m. and 9 p.m. Saturday should be mostly manageable across a large portion of the Chicago area.
A few isolated showers or scattered sprinkles could still develop, so completely dry conditions are not guaranteed. However, widespread rainfall is not currently expected to wash out evening trick-or-treating plans.
Temperatures should remain in the middle to upper 50s, with relatively light winds.
Parents taking children outdoors may still want to prepare for occasional drizzle. Costumes with an extra layer underneath could also help keep younger trick-or-treaters comfortable as temperatures fall through the evening.
Overall, the forecast suggests that most families should have an opportunity to enjoy Halloween activities, although checking local conditions before heading out remains important.
Sunday Forecast: Clouds Continue as Temperatures Warm
After Halloween, cloudy conditions are expected to remain across the Chicago region on Sunday.
The good news is that temperatures should become a few degrees warmer compared with Saturday. Afternoon highs are forecast to reach the middle 60s, creating somewhat milder conditions for the final day of the weekend.
Although clouds will continue to dominate the sky, Sunday is not currently showing the same level of concern for spotty showers during Halloween activities.
Monday Weather: A Few Showers Still Possible
The chance of rain on Monday has decreased in the latest forecast, but a few showers cannot be completely ruled out.
High temperatures should remain around the middle 60s, while southeast winds are expected to blow at approximately 5 to 15 mph.
The combination of relatively mild temperatures and occasional cloud cover should keep conditions from feeling particularly cold.
Residents planning outdoor activities at the beginning of the workweek should continue monitoring updated forecasts for any changes in precipitation chances.
Election Day Forecast: Temperatures Could Approach 70 Degrees
Tuesday’s forecast is also showing some changes as newer weather data suggests that rain may hold off until later in the day.
Winds are expected to turn more southerly, helping bring warmer air into the Chicago area. Afternoon temperatures could approach 70 degrees, which would be roughly 15 degrees above normal for early November.
This warmer pattern could provide a noticeable change from the cooler Halloween conditions. However, the possibility of rain later Tuesday means outdoor plans may still require some flexibility.

Rain Chances Increase Wednesday Before Drier Weather Returns
Wednesday currently appears to have better chances of rain compared with Monday and Tuesday. After that, conditions are expected to become drier by Thursday and Friday as the forecast pattern changes.
Daytime temperatures should generally remain above average, with highs staying in the 50s and 60s throughout much of the week. Overnight lows are also expected to hold in the 50s across a majority of the region.
What Chicago Residents Should Know Before Halloween
The biggest weather concern for Halloween is the possibility of occasional light showers rather than a widespread washout.
Families heading out between 4 p.m. and 9 p.m. should generally find manageable conditions, with temperatures in the 50s and fairly light winds.
Still, a few isolated sprinkles could appear, making it useful to carry a light rain jacket or have a backup plan for outdoor celebrations.
Chicago’s Halloween forecast looks mostly manageable, but a few passing showers could make things slightly inconvenient for trick-or-treaters.
