Chance of Rain

• July is one of the wetter months in Chicago, with an average of 3.5 to 4 inches of rainfall.
• Most rain comes in the form of brief but heavy summer storms, so rain delays are possible, but they usually don’t last long.

Wind

• Winds are light to moderate, typically around 5–10 mph, but they can be a bit stronger near the lake or during storms.

Sun Protection

• The UV index is high in July. If you're outside for a while, be sure to wear sunscreen, sunglasses, and a hat to protect yourself from the sun.

Pro Tip

• Stay hydrated! Bring a refillable water bottle if allowed, and take breaks in the shade when you can, especially if you’re walking around Grant Park all day.
