What is Chicago's Average Snowfall?

Chicago's climate is characterized by cold, snowy winters. The average annual snowfall across the city typically hovers around 36 inches. However, this is just an average, and actual amounts can vary significantly from year to year and even between different parts of the metropolitan area. Factors like proximity to Lake Michigan can influence snowfall patterns, sometimes leading to lake-effect snow events that intensify accumulation in certain locales.

Seasonal Snowfall Variations

While the total annual average provides a general idea, snowfall isn't evenly distributed throughout the winter months. Typically, the snow season begins in November and can extend through April, though significant accumulations are most common between December and March. January is historically Chicago's snowiest month, often receiving the largest share of the winter's total accumulation.

Factors Influencing Snowfall Amounts

Several meteorological factors contribute to Chicago's snowfall totals:

• Lake Michigan: The lake's moisture can fuel winter storms, especially when cold air masses move across the warmer waters, leading to enhanced snowfall (lake-effect snow).
• Storm Tracks: The path of low-pressure systems, or storms, passing through the region dictates the amount and type of precipitation received.
• Temperature: For snow to fall and accumulate, temperatures must be at or below freezing (32°F or 0°C). Even slightly warmer temperatures can result in rain or a wintry mix instead of snow.

How Much Snow Did Chicago Get Last Winter?

Pinpointing the exact snowfall for a specific past winter requires consulting historical weather data. For instance, let's consider the recent winter of 2023-2024. Official records from O'Hare International Airport (ORD), the National Weather Service's primary reporting station for Chicago, indicate the following:

• Total Snowfall (2023-2024 Season): The total snowfall for the 2023-2024 winter season at O'Hare was approximately 38.4 inches. This figure is slightly above the city's annual average of 36 inches.
• Notable Snow Events: While no single, massive blizzard defined the season, there were several notable snowfalls. A significant event occurred in late January 2024, bringing around 6-8 inches of snow to parts of the city. Other smaller accumulations occurred throughout December and February.
• Comparison to Average: This season's snowfall was relatively close to the long-term average, indicating a typical winter in terms of snow accumulation.

(Note: Snowfall data can vary slightly depending on the specific reporting location within the Chicago metropolitan area. O'Hare is the official NWS site.)

Previous Winters: A Snapshot

To provide context, here's a look at snowfall in a few preceding winters:

• 2022-2023 Season: This winter was notably warmer and drier than average. O'Hare recorded approximately 16.0 inches of snow, significantly below the annual average.
• 2021-2022 Season: This was a much snowier winter for Chicago. O'Hare recorded 39.5 inches of snow, just above the average.
• 2020-2021 Season: This winter saw above-average snowfall, with O'Hare receiving 37.0 inches.

These examples illustrate the year-to-year variability in Chicago's snowfall.

Chicago Snowfall Records: The Extremes

Chicago's history includes some truly remarkable snowfall events that stand out from the averages. These extreme events often cause significant disruptions and are remembered for years.

The All-Time Snowiest Winter

The record for the snowiest winter season in Chicago belongs to 1879-1880, when an astonishing 89.8 inches of snow fell. This figure remains the benchmark for extreme snowfall in the city's recorded history.

Major Snowstorms and Blizzards

Several historic snowstorms have paralyzed Chicago:

• The Blizzard of 1967: This infamous storm dropped 23.1 inches of snow on Chicago in just 29 hours (January 26-27, 1967). It caught residents largely unprepared, shutting down the city and leading to numerous travel complications and economic losses.
• The Blizzard of 1979: Another major blizzard hit Chicago from January 12-13, 1979, dumping 20.0 inches of snow. Similar to the 1967 event, it caused widespread disruption.
• The Groundhog Day Blizzard of 2011: This storm brought 20.2 inches of snow to Chicago on February 1-2, 2011. It stranded thousands of travelers at O'Hare and Midway airports and caused significant traffic jams.
• January 2011 Snowstorm: Preceding the Groundhog Day blizzard, a significant snowstorm on January 6-7, 2011, dropped 12.0 inches on the city.

These record events underscore the potential for extreme weather and the importance of robust emergency preparedness. — Is Halloween A National Holiday? Facts & Myths

Why Does Chicago Get So Much Snow?

Chicago's location and geographical features contribute to its reputation as a snowy city:

1. Continental Climate: Chicago lies within a humid continental climate zone. This means it experiences significant temperature variations between seasons, including cold winters conducive to snow.
2. Proximity to Lake Michigan: As mentioned earlier, Lake Michigan plays a crucial role. In late fall and winter, cold air masses moving across the relatively warmer lake water pick up moisture. When this moisture-laden air rises and cools, it can produce heavy bands of snow, often referred to as lake-effect snow, particularly on the snow belts downwind of the lake (often east and south of the city).
3. Storm Tracks: Chicago is situated in an area frequently impacted by storm systems moving from the west and southwest (like the Colorado and Alberta clippers) or larger systems developing in the Gulf of Mexico. These storm tracks can bring substantial precipitation, which falls as snow when temperatures are cold enough.

How to Track Chicago Snowfall

Staying informed about current and upcoming snowfall is essential for planning. Here's how you can track Chicago's snow:

• National Weather Service (NWS): The NWS Chicago office provides detailed forecasts, current conditions, and historical weather data. Their website is an excellent resource for official information.
• Local News Outlets: Chicago television stations and radio channels offer weather reports, often with localized radar and snowfall predictions.
• Weather Apps and Websites: Numerous reliable weather apps (e.g., The Weather Channel, AccuWeather, Weather Underground) and websites provide real-time updates, radar imagery, and hourly forecasts.
• Chicago Department of Streets and Sanitation: For information on snow removal and plowing operations, this city department is a key resource during snow events.

What to Do During a Chicago Snowfall

When snow accumulates in Chicago, preparedness and safety are paramount:

• Stay Informed: Monitor weather forecasts closely.
• Travel Safely: If you must drive, ensure your vehicle is equipped with snow tires or chains, keep a full tank of gas, and pack an emergency kit. Allow extra travel time and drive cautiously.
• Public Transportation: CTA (Chicago Transit Authority) services may be impacted by heavy snow. Check their website for service alerts.
• Home Preparedness: Ensure you have adequate heating, food, water, and any necessary medications. Keep sidewalks and driveways clear to prevent ice buildup and ensure accessibility.
• Follow City Advisories: Be aware of any parking restrictions (like snow routes) or advisories issued by the city.
