The adverse weather has significantly impacted Chicago residents and businesses. Outdoor events, including weddings, sports leagues, and festivals, have been disrupted or canceled due to rain, storms, and high humidity. Businesses reliant on outdoor activities, such as Chicago Water Sport Rentals and O’Brien’s Riverwalk Café, have reported significant revenue losses, with some experiencing a 20% drop in sales compared to previous years. The high humidity and frequent rain have also led to an increase in mosquito activity, particularly from the invasive Asian Tiger mosquito, which poses a health risk to residents. Additionally, the poor air quality in July, caused by wildfire smoke, has further compounded the challenges for outdoor activities.
