June weather in Chicago
Comfortably warm — around 25°C / 77°F, easy shirtsleeve weather, with rain on about 11 days, so keep a layer handy. The days are long too — close to 15 hours of light — so the evenings stay open for walking once the heat drops.
- Chicago gets rain on about 11 days in June, so the odds of being caught out are real. What earns its bag space is a shell that packs to nothing, dries fast and has a hood that survives wind; a heavy waterproof is overkill and an umbrella is one more thing to carry through crowds.
