atmosphere. Chicago has distinct seasons, with a short spring, when
temperatures are moderate and nights frosty. Summers are hot, sunny
and humid, from June to the end of September, and are prone to
thunderstorms. August is usually the wettest month of the year.
Autumn is a lovely time of year when the air is crisp and cool,
with blue skies and sunshine. Winters in Chicago are icy and prone
to cold, harsh winds. Snow is common.
