St. John's earns a page because one month carries a large share of a heavy year. January averages 58.2 cm of snow in ERA5, inside an annual total of 228.2 cm, while the January temperature mean is only -1.9°C. That is a mild, snowy month, not a prairie deep freeze. Sydney records 225.1 cm a year under the same method.
November through March accounts for 200.8 cm of the 228.2 cm annual average at this point. Our model preload for this page is high snow tolerance and standard cold sensitivity. That setting is editorial. It is not a threshold published by a school board. The live score uses the hourly forecast, not the ten-year average. There is no centimetre rule on this page for closing schools in St. John's.
