A source-backed view of historical freeze risk at this weather station. Use it to understand the season, not as a promise about your garden or this year’s weather.
Year-round freeze riskA conventional frost-free season is not supported.
This station’s normal record indicates freezing risk across the year. A standard last-spring/first-fall planting model would be misleading; use local guidance for the elevation and climate.

Put the data in context
A baseline.
Not a forecast.
Weather stations measure a particular location. Differences in elevation, exposure, nearby water, terrain and urban heat can change conditions in an individual garden.
- 32°F is the station air-temperature threshold; visible frost on leaves can differ.
- Median dates still leave substantial historical freeze risk.
- Historical normals summarize 1991–2020, not current weather.
- Crop suitability requires regional horticultural guidance, soil warmth, cultivar and day length.
