Ah, snow days! Instead of taking a math test, you get to spend all day watching TV in your pajamas -- or playing in the snow with your friends! Everyone loves a snow day now and then, but how do you know if the murky gray sky above you is going to unleash a foot of snow -- or be nothing more than a disappointment? Well, though there's no way to be 100% sure if your school will have a snow day, [1] there are many things you can do to increase your chances of figuring it out. If you want to know how to predict a snow day, see Step 1 to get started.

  1. Though you may think that you'll have a snow day for sure because it's snowing the evening before school, you've got to take the hourly forecast into account. If it says that it's going to stop snowing by 2 or 3 am, or even a bit later, then the snow plows may be able to remove the snow in time for the school buses to run. For the highest chances of a snow day, you want to see the heaviest snowfall between 5-7am. [2]
    • However, it also doesn't hurt if the forecast says it'll start to snow heavily during school hours, because your school administrators will not want to deal with the mess of trying to get everyone safely home in the middle of a snowstorm.
    • Sometimes, you may also get an early dismissal, which is better than nothing.
    • You should also look for changes in the forecast. If it drastically changes and it looks like you'll be getting more snow than expected, then you're in a good place!
    • Consider how many inches of snow you will get. If it will be snowing all day but there will only be 1–2 inches (2.5–5.1 cm) of precipitation, then you may still have to go to school.
    • Check if a winter weather advisory is in effect during school hours. Winter weather advisories are issued by the government when dangerous weather is expected. If the government considers the upcoming weather to be dangerous, chances are your school will too.
    • Consider the possibility of ice. If rain is expected alongside freezing temperatures, you are likely to get some ice. This is good news because if the ice freezes onto the roads, transportation may not be as safe and therefore school is more likely to get cancelled.
  2. Though this isn't as important as figuring out how much snow is expected to fall, if a storm has hype about it -- which means that you hear not only students, but also teachers or even administrators, talking about it -- then it's more likely that you will have a snow day. This is because, if it's very big news, administrators are more likely to see that the snow is a threat. Remember, the administrators don't want to let down the people who expect snow days, or to put them in dangerous situations.

  3. If your mom happens to be best friends with the school administrator/superintendent, or someone else who is high up on the school ladder, then you'll be more likely to hear about a snow day first. However, keep in mind that everyone will be hounding this person, and sometimes these decisions aren't made until early the next morning.
    • Some people also believe that if the bus drivers think that there will be a snow day tomorrow, then it may be more likely that school will be cancelled.
    • If your parents know some teachers at your school, or if one of your friends happens to have teachers in the school as parents, then he or she may have some insight into whether or not you'll have a snow day earlier than the general public.
    • Also, some superintendents even communicate snow days over Twitter. Though you'll be called soon after the decision is made, you can have a leg up by checking out your administrator's Twitter page, if he or she has one.
  4. Check the current closures of other public facilities in your area. If there are events being cancelled or schools already closing the night before in your area, then your chances are higher. If a school administrator sees that the surrounding schools or nearby public places are being closed down, then he or she will feel more pressure to do the same. This isn't a surefire way to know what will happen, but it certainly won't hurt!
  5. If a school that is located just a few miles away is closed, your school will probably be closed too. If you have friends from other schools, you can just ask them directly. If not, you can check out the local news and the local radio. Again, this doesn't make it 100% likely that you'll have a snow day yourself, but it does raise your chances.
  6. If you really feel clueless, check out your Facebook, Twitter, or Instagram accounts to see what people are saying about the oncoming snow. Even if you don't get an answer there, you may see that there's a lot of hype, which can increase the chances of the building storm! And if you can find a local teacher or administrator on Facebook or Twitter, they may have something to say about it. [3]
  7. There are several online snow day calculators that have a good success rate in predicting whether or not there will be a snow day. All they need to know is your zip code, and they will consider the weather-related factors, as well as the likelihood that someone in your district will call for a snow day. [4]
    • If you are on a mobile device, you can also search the app store for "snow day" to see all the snow day prediction tools available.
    • Make sure any snow day calculators you download from the app store are relevant to your country. Most of these calculators only predict closures in the USA and Canada, so they might not be an option if you live elsewhere.
  8. If you have a few inches of snow in Georgia, you may be more likely to have a snow day than you would if you lived in Maine, where the people in charge may be better prepared to deal with removing the snow, salting the roads, and maintaining order. If you have never seen a snowplow on your street, then those 2 inches (5.1 cm) of snow may really scare people off!
  9. Some districts and schools are much more trigger happy when it comes to making the decision to cancel school. If your school board has a good track record of canceling school when there has been a threat of snow, then you may be in good luck. On the other hand, if you've had to come to school while it's snowing and then walk home through the slush again and again, then you may be less likely to have a snow day. If your school is an urban district that largely walks, then you might not have a snow day, unless the snow becomes ice or the temperature is below zero. But if your district is a rural district with many busses that needs plowed roads, then you might have a higher chance of a snow day.
  10. This means having all your homework done and packed away as it normally would be, but it also means you must mentally expect there will be school the next day. Several snow day predictions have been wrong. You don't want to wake up to disappointment -- or panic because you haven't studied for your math test! If school is cancelled, then you are in for a surprise! It makes the fun even better. Even if it's not cancelled, you can do your research and be the first to know about the next big snowstorm to hit your town!
    • And hey, if you don't end up getting a snow day, it's not the end of the world. Public schools have a certain allotment of snow days for each year, and if you get too many snow days, you may have to come to school during holidays, or even to go to school late into the summer!

  • Question
    How long will it take for me to find out if buses are cancelled?
    Community Answer
    It depends on your school district, but usually snow days are called 2-3 hours before school starts. Also, check for nearby business closings, as that could increase the probability of a snow day.
  • Question
    How many inches of snow does there have to be?
    Community Answer
    The amount of snowfall required to declare a snow day will vary from district to district and according to which country you're in. There may also be a wind or wind chill factor taken into account. Your school district decides the amount based on the safety of your local roads, the availability of transport and the feasibility of students moving around the town or city areas to get to school. Check your school's website for more details, or as at the front office.

      • Check your school's Facebook or website to see if they said they're closing or having a delayed opening. Be sure to check the night before, because some schools will announce a snow day in advance based on the forecast.
      • If you drive, make sure to check the roads around the neighborhood to see how they feel before driving all the way to school. If the roads look really bad, it's not safe to drive.
      • If you go to a public school, then think of all the snow days you have had already. If the weather is the same as the last snow day, you'll probably have another one.
      • If you do have a snow day and you have homework on the computer, check to see if you teacher assigned you work to do from home. It has happened to me.
      • Look at an app called Snow Day Calculator and also check Twitter.
