We connect a real Census place to the nearest agricultural NOAA station, then show the distance and the limitations. This is not a locally validated planting calendar.
CDP · Census 2026A seasonal station and a mild-climate or limited-data station are not interchangeable. The nearest source has not been replaced to force a calendar.

The line connects Northridge’s published Census internal point to the weather station. It does not measure terrain, elevation differences or your garden’s microclimate.

1991–2020 station normals
32°F minimum-temperature threshold
Last spring freeze
Among cold seasons with a freeze: probability of the last occurrence on this date or later.
The 10% date is later in spring than the median: a more cautious historical reference, still not a guarantee.
First fall freeze
Among cold seasons with a freeze: probability of the first occurrence on this date or earlier.
The 10% date is earlier in fall than the median: a more cautious harvest-planning reference.
These percentages are conditional on a cold season containing a 32°F freeze; they are not probabilities across all years. They describe historical climate, not this season’s forecast. The spring and fall probability directions are intentionally different. A garden can be warmer or colder than the reference station.

Date probabilities apply among cold seasons with a 32°F freeze, not all years. Check each station’s annual occurrence and quality before comparing.
