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.

A reference, not your back garden

3.3 miles S
from the Census reference point.

The line connects Mitchellville’s published Census internal 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.

The 10% date is later in spring than the median: a more cautious historical reference, still not a guarantee.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.

Available alternative-station median spread: spring 11 days; fall 9 days. 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.
