Last and first frost dates are 33% probability. Calculated using 1981-2010 Climate Normals from Environment Canada.
Our frost dates are based on 1991–2020 climate data from the National Oceanic and Atmospheric Administration (NOAA). We use a 30% probability threshold, meaning there’s about a 3 in 10 chance frost will occur before or after the given date. Because microclimates vary—your backyard might be warmer or cooler than nearby towns—use these dates as a flexible guide, not a guarantee.
