Checking the forecast closer to your travel dates will provide a more accurate picture of the expected conditions.
Keep in mind that the proximity to Lake Michigan can also influence Chicago's weather. The lake can have a moderating effect, keeping temperatures slightly cooler in the summer and warmer in the winter. However, it can also create lake effect weather patterns, such as sudden temperature drops or increased cloud cover, especially along the lakefront. When planning activities near the lake, be prepared for potentially different conditions than in other parts of the city. You can also check resources like the National Weather Service (https://www.weather.gov/) for detailed forecasts and information about lake effect conditions.
Rainfall and Sunshine in September
September in Chicago typically brings moderate rainfall, with an average of around 3.5 inches (89 mm) of precipitation throughout the month.

Despite the rainfall, September still offers plenty of sunshine in Chicago. The city enjoys an average of 7-8 hours of sunshine per day during the month, providing ample opportunities for outdoor activities and sightseeing. The days are also still relatively long in September, with the amount of daylight gradually decreasing from around 13 hours at the beginning of the month to about 11.5 hours by the end. This allows for extended exploration of the city's attractions and neighborhoods.
The combination of moderate rainfall and ample sunshine contributes to the vibrant foliage that begins to emerge in September. As the temperatures cool, the leaves on the trees start to change color, creating stunning displays of reds, oranges, and yellows. This makes September an excellent time to visit Chicago's parks and gardens, such as Lincoln Park and the Chicago Botanic Garden, to witness the beauty of the fall foliage. To get the most out of the sunny days, consider visiting outdoor attractions like Millennium Park or taking a stroll along the Chicago Riverwalk. You can also explore resources like the Illinois Department of Natural Resources (https://www.dnr.illinois.gov/) for information on fall foliage updates and scenic drives in the Chicago area.
What to Wear in Chicago in September
Dressing for Chicago's weather in September requires a bit of flexibility due to the fluctuating temperatures. Layering is key to staying comfortable throughout the day, as the mornings and evenings can be cool, while the afternoons may be pleasantly warm. Start with a base layer of lightweight clothing, such as t-shirts or long-sleeved shirts, and add a sweater or jacket for warmth.
A light to medium-weight jacket is essential for September in Chicago. A versatile jacket, such as a denim jacket, bomber jacket, or a lightweight raincoat, can be easily layered over other clothing and will provide protection from both the chill and potential rain. For colder evenings or outings near the lake, you may want to consider bringing a heavier jacket or coat. A scarf, hat, and gloves can also be useful accessories, especially later in the month.
In terms of footwear, comfortable walking shoes are a must for exploring Chicago's many attractions and neighborhoods. Sneakers, walking shoes, or comfortable boots are all good options. If you plan on attending any dressier events, you may also want to pack a pair of dress shoes. Don't forget to pack socks that are appropriate for the weather and your chosen activities. Always check weather forecasts before you go, resources like AccuWeather (https://www.accuweather.com/) offer detailed information and long-range forecasts that can be very helpful.
