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.

Using a reviewed mainland city reference.

The Census geography includes extensive water and offshore islands; its published internal point is offshore. Use a reviewed mainland reference for station matching, not a garden location. Distances, station comparisons and the forecast link all use this point.

Nearby stations have different climate statuses.

A seasonal station and a mild-climate or limited-data station are not interchangeable. The nearest source has not been replaced to force a calendar.

A reference, not your back garden

0.7 miles SW
from the mainland city reference point.

The line connects San Francisco’s reviewed city reference point to the weather station. It does not measure terrain, elevation differences or your garden’s microclimate.

Full station data
Proximity is not a climate-validation score. Place elevation is unavailable in this Census source, so we cannot verify the elevation difference. The nearest station is never silently replaced by a colder one to create a planting calendar.

A conventional seasonal freeze calculation is not supported by this reference.

No modeled annual freeze occurrence. This may reflect a mild or high-elevation climate, infrequent freezing, or limited-quality values. We preserve the source status rather than inventing dates.

Available alternative-station median spread: spring not comparable; fall not comparable. This is a comparison of source references, not a measure of garden uncertainty.

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