Rochester, New York: freeze dates & growing season
Three different things get called “Rochester” here, so this page is explicit about all three: the metro label (Rochester), the anchor geography (Census ZCTA 14604, a downtown ZIP-code area), and the climate record (the NOAA station below). Windows are calculated from the station — not from your street address.

These windows describe typical years (1991–2020 climate normals), not this year's forecast. Freezes happen outside them — especially in frost pockets, valleys, and urban edges. Watch the forecast before committing tender plants.
