Chicago, IL – Trick-or-treaters in the Great Lakes and Midwest may need to keep umbrellas handy as Halloween 2025 approaches.
According to the Farmers’ Almanac extended outlook, much of the region, including Illinois, Wisconsin, Indiana, Michigan, Kentucky and Ohio, is expected to start the final days of October under fair skies before showers arrive in parts of Michigan, Ohio and surrounding areas by the holiday.
From Tuesday, Oct. 28 through Thursday, Oct. 30, weather conditions are projected to be largely cooperative for outdoor events, with mild to cool temperatures and dry skies in most locations. However, the forecast suggests that by Friday, Oct. 31, a shift toward wetter conditions could affect the eastern portion of the region, particularly in Michigan and Ohio, while states farther west such as Illinois and Wisconsin may remain mostly dry.
Seasonal averages for late October in the Great Lakes typically bring daytime highs in the 50s and low 60s, with evening temperatures cooling into the 40s. If showers do arrive Friday evening, it could lead to damp and chilly conditions for Halloween festivities in certain areas.
Meteorologists caution that long-range forecasts, such as the Farmers’ Almanac predictions, provide a general trend rather than exact local conditions. As the date approaches, local National Weather Service offices will issue updated short-term forecasts with more precise timing for any rainfall.
Parents planning Halloween routes are encouraged to prepare for cooler evening temperatures and the possibility of light rain, especially in eastern portions of the Great Lakes region. Costumes with layers and weather-resistant footwear can help keep the night enjoyable for trick-or-treaters.
This year’s Halloween falls on a Friday, giving families the opportunity to extend celebrations into the weekend — rain or shine.
