Any accumulation or hard freeze
Snow days in Miami are rare enough to be historically notable. Most winters see zero events that approach a school closure threshold. When they happen — typically once every 3–10 years — they close schools not from accumulation but from hard freezes that burst water mains and ice over elevated roadways overnight. The threshold here is binary: any measurable winter-weather event is a closure.
Florida has essentially no winter infrastructure. Plows, salt trucks, and pre-treatment equipment exist only in token quantities — not because of poor planning, but because the cost of stockpiling for events that happen once a decade isn't economically justified. When an event does arrive, the entire region shuts down for several days while natural thawing resolves the conditions.
School closure decisions in Miami are influenced less by snow forecast numbers and more by hard-freeze risk. A night with temperatures in the low 20s and overnight moisture on roads produces black ice that southern drivers have no experience handling. Districts will close schools preemptively when any freeze is expected, and keep them closed until above-freezing temperatures return reliably.
Miami averages 0 inches of snow per year, which is functionally zero. Winter weather events that could close schools happen once every few years on average.
