Growing Season Length
Your frost-free season is the stretch between the last spring frost and the first fall one, the window things can grow outside. Set your place to see how long yours runs and where it lands among every station we track.

What the season measures
Frost-free days count the typical span from the average last spring frost to the average first fall frost. It is the single best summary of how much you can grow: a long season ripens tomatoes, peppers, and melons outdoors, while a short one rewards quick, cold-hardy crops and a head start indoors. The ranking compares your nearest station with every other we hold, so a high percentile means a genuinely long season for Canada.
