What Can Cancel School?

Have you ever gotten ready for school, packed your bag, and then suddenly heard that school is canceled? It can be a surprise, but school cancellations happen a lot more than most people realize. There are many reasons why schools might decide to cancel school, and understanding them helps students know why missing a day might be necessary. From weather problems to safety concerns, a variety of things can disrupt school schedules.
One of the biggest reasons schools cancel school is because of weather conditions. In places where it snows a lot, heavy snowstorms can make roads dangerous or impossible to drive on. When the streets are covered in ice or deep snow, school buses can’t safely pick up students, so schools often decide to close for the day. For example, in states like Michigan and Minnesota, it’s common to cancel school several times during winter because of snow or ice. But it’s not just snow—hurricanes or heavy rainstorms can also cause schools to close. Flooding from storms can make it unsafe for students and teachers to get to school, and sometimes power outages happen because of the weather.
Other reasons schools might cancel school include:
- Health Concerns: Flu outbreaks or other illnesses can spread quickly, so schools close to keep everyone safe.
- Power Outages: Without electricity, schools can’t run computers, lights, or heating.
- Natural Disasters: Earthquakes, fires, or floods can damage schools or make the area unsafe.
- Safety Issues: Threats or emergencies may force schools to close suddenly.
Here’s a simple table showing some common reasons schools cancel school and how they affect students:
| Reason | How It Affects School | Example Locations or Situations |
|---|---|---|
| Weather | Dangerous roads, power outages | Snow in Michigan, hurricanes in Florida |
| Health | Risk of illness spreading | Flu season, COVID-19 |
| Power Outages | No electricity for lights or heating | After storms or technical failures |
| Natural Disasters | Damage or unsafe conditions | Wildfires in California, floods in Texas |
| Safety Issues | Security threats or emergencies | Local threats or emergencies |
Schools make these decisions to keep students and staff safe. Sometimes, cancelling school is the best option, even if it means missing a day of learning.
Understanding these reasons helps students see why missing a day isn’t just about convenience—it’s about safety and health. In the next section, we’ll explore how often schools cancel school for these reasons and what that looks like across the country.
How Much and What Exactly Causes Schools to Cancel School?

School cancellations are complicated events influenced by many factors—nature, health crises, infrastructure, and safety issues. Understanding what causes these cancellations and how frequently they happen helps students, parents, and educators prepare better.
Let’s dive deep into each major cause of school cancellation, analyzing frequency, typical duration, regions affected, and broader impacts.
1. Weather-Related School Cancellations: The Biggest and Most Complex Category
Snow and Ice Storms: The Northern and Mountain States’ Annual Challenge
Snow and ice are the classic causes of school cancellations, especially in northern states and mountainous regions:
- Frequency: On average, northern states like Minnesota, Wisconsin, Michigan, and New England experience between 5 and 15 snow-related cancellation days per year. Some years with severe winters can see even more.
- Why: Ice storms, freezing rain, and heavy snow make roads unsafe for buses and cars. Cold temperatures pose risks to children waiting for transport.
- Impact on Learning: The loss of 10+ days can delay curriculum progress and force school years to extend into summer.
- Example: In the winter of 2018-2019, Buffalo, NY schools closed for 14 days due to heavy snow, one of the highest totals nationwide.
- Regional Differences: Southern states rarely see snow cancellations, but some mountain towns like Aspen, Colorado, might.
Hurricanes and Tropical Storms: The Coastal States’ Seasonal Risk
Hurricanes are powerful storms that cause flooding, wind damage, and power outages:
- Frequency: Gulf Coast and southeastern states typically face 1-3 hurricanes or tropical storms annually, with schools cancelling between 2 and 10 days per event.
- Why: Evacuations, flooded roads, and building damage force closures.
- Duration: Closures can last several days or weeks after severe hurricanes due to recovery efforts.
- Example: Hurricane Maria in 2017 caused Puerto Rico schools to close for months after massive infrastructure damage.
- Additional Challenges: Power loss and mold after flooding create long-term issues beyond immediate closures.
Flooding and Heavy Rain: Localized but Increasingly Common
Flooding often strikes unexpectedly and can shut down schools even away from coasts:
- Frequency: Flood-prone areas, like the Mississippi River valley and parts of the South, see 1 to 5 days of flooding-related cancellations annually.
- Causes: River overflow, blocked roads, water damage to school facilities.
- Example: The Midwest “Great Flood” of 1993 caused widespread school closures for weeks in affected areas.
- Trends: With climate change, severe rain events causing floods are increasing in frequency.
Extreme Heat: A Growing Issue in the South and Southwest
- Frequency: Extreme heat cancellations are still rare but are rising in places like Texas and Arizona.
- Why: Lack of air conditioning and power outages during heatwaves can make schools unsafe.
- Example: In 2022, some Texas school districts canceled school for a day during record heat to protect students.
- Future Outlook: Scientists warn this could become a more frequent cause with global warming.
2. Health-Related School Closures: Disease Outbreaks and Pandemics
Seasonal Flu and Other Illnesses: Annual Interruptions
- Frequency: Flu outbreaks cause many schools nationwide to cancel for 1 to 2 weeks most years.
- Why: High student and staff absenteeism risks spreading illness further.
- Example: The 2017-2018 flu season saw some districts in Ohio close schools for a week due to widespread illness.
- Additional Illnesses: Norovirus (stomach flu), chickenpox, and measles outbreaks occasionally cause short closures.
COVID-19 Pandemic: Unprecedented and Long-Lasting Closures
- Duration: Schools across the US and worldwide closed for 50 to 120+ days at peak times.
- Shift to Remote Learning: Many schools transitioned to online classes, highlighting digital divide issues.
- Impact: Research shows lost instructional time, widening achievement gaps, and mental health challenges for students.
- Example: New York City schools closed from March to June 2020, the longest closure in recent history.
3. Power Outages and Infrastructure Failures
Schools depend heavily on utilities like electricity, heat, and water. When these fail:
- Power Outages: Often caused by storms or equipment failure, power outages lead to 1-3 day closures.
- Example: Texas winter storm of 2021 caused blackouts that forced schools to close due to heating loss.
- Heating System Failures: Especially in winter, broken heating systems cause cancellations to prevent health risks.
- Plumbing or Water Issues: Water main breaks or sewage problems can close schools temporarily.
4. Natural Disasters Beyond Weather: Wildfires, Earthquakes, Tornadoes
Wildfires: Increasingly Frequent in Western States
- Frequency: Wildfire seasons in California and the Pacific Northwest cause days to weeks of closures.
- Why: Smoke creates unsafe air quality, and evacuations force closures.
- Example: The 2020 California wildfire season closed schools for over two weeks in some districts.
Earthquakes: Sudden and Severe Impact in Seismic Zones
- Impact: Earthquakes cause immediate damage, forcing closures for days to weeks.
- Example: The 2014 Napa earthquake led to school building inspections and temporary closures.
Tornadoes: Sudden Closures in Tornado Alley
- Frequency: Tornadoes mostly cause damage in the Midwest and South, leading to closures of a few days to weeks.
- Example: After the 2011 Joplin tornado, local schools were closed for several weeks during rebuilding.
5. Safety Threats and Security Emergencies
- Schools occasionally face emergency situations like lockdowns due to police activity or threats.
- Closures range from hours to days depending on the situation.
- Safety remains the top priority in these cases.
6. The Bigger Picture: How Much School is Lost Each Year?
| Cause | Average Days Cancelled (Nationally) | Max Closure Length | Primary Regions |
|---|---|---|---|
| Snow and Ice Storms | 4-10 days | Up to 15 days | Northern US, Mountain states |
| Hurricanes and Tropical Storms | 2-7 days | Weeks | Gulf Coast, Southeast |
| Flooding | 1-5 days | Weeks | River Valleys, Coasts |
| Extreme Heat | <1 day | 1-2 days | South, Southwest |
| Seasonal Flu | 5-14 days | Up to 2 weeks | Nationwide |
| COVID-19 Pandemic | 50-120+ days | Months | Nationwide |
| Power Outages | 1-3 days | Several days | Nationwide |
| Wildfires | Several days to weeks | Weeks | Western US |
| Earthquakes | Variable | Weeks | California, Fault zones |
| Safety Threats | Hours to days | Several days | Nationwide |
7. Regional Differences: Why Your Location Matters
- Northern states: Heavy snow and ice dominate cancellations.
- Southern states: Hurricanes and heat are key causes.
- Midwest: Flooding and tornado damage are frequent risks.
- West Coast: Wildfires and earthquakes cause unique challenges.
8. Impact on Students, Families, and Communities
- Learning disruptions: Frequent cancellations slow curriculum and test preparation.
- Childcare struggles: Parents must find last-minute care or miss work.
- Nutrition issues: Many students rely on school meals, which they miss during closures.
- Mental health: Uncertainty and isolation affect students emotionally.
Schools work hard to balance these challenges while prioritizing safety.
