<p>Chicago is currently about 97 degrees. That won’t last until October, but your son can probably survive without a winter coat until about early November. It’s more important to get him lots of layers: fleece, sweaters, warm socks. My son definitely overpacked even tho he attends NU. It didn’t snow enough.</p>
<p>You wouldn’t believe how I prepared my son for snow and harsh winters. Boots, coats, face gear, you name it. Then one time he left his boots home by mistake and never needed them</p>
