Expats who plan on relocating to Chicago will experience all the extremes of this city’s climate. There are four distinct seasons, each characterised by specific conditions.

September brings mild, crisp weather as autumn approaches. Winter, from late November to early March, is marked by heavy snowfall, including blizzards. It's not uncommon for the temperature to hover at 32°F (0°C) for days on end. During very cold periods, the temperature can drop to -4°F (-20°C) or lower.

Chicago’s springs are from mid-March to May with a gradual shift from cold to warm conditions throughout the season. June heralds the start of summer, which is typically hot, sunny, humid and prone to evening thunderstorms.
