Quebec Agroclimate - Average length of the frost-free season (Tmin > 0, -1, -2, -3 or -4 °C)

Average number of consecutive days with a minimum temperature higher than a freezing temperature threshold (0, -1, -2, -3 or -4 °C), i.e., between the last spring frost and the first autumn frost. The calculation is based on the period between 1979 and 2008.

This analysis was based on temperature values interpolated at 10 km using the ANUSPLIN method, based on data from the Ministère du Développement durable, de l'Environnement et des Parcs du Québec and from Environment Canada.

These values give a general indication of the frost risk for a region, but they are not necessarily representative of a specific site. Frost risk varies locally depending on a number of factors, particularly topography and proximity to a body of water.

The length of the frost-free season is an important criterion to consider in evaluating the potential of a crop or cultivar in a given region.
