Based on the station’s daily minimum temperature, 1995–2024. “Freeze” here means a daily low at or below the threshold, which is not the same as visible frost. Your yard can differ by several degrees and days from an airport weather station, so use these as planning odds, not guarantees.
The median stretch between the last spring freeze and the first fall freeze (the freeze-free season) was about 102 days.
