Distance alone does not establish a climate match. Elevation, coastal exposure, urban shelter and soil can differ; the postal location has no verified garden elevation.
The postal reference point is near 45.601°, -88.107°. At the nearest qualifying NOAA station reference (GOODMAN SANITARY DIST, WI US), July is the warmest month on average (18.4°C), while January is the coolest (-10.1°C). This does not measure your garden’s temperature.
Reference monthly means are below freezing in January, February, March, November, December. This signals a need to assess protected growing, not a calculated planting prohibition. Broccoli tolerate some cold, but variety, plant age and exposure still matter. A monthly average cannot identify a safe planting day.
Light at your latitude
At 45.601° N, the length of the day changes independently of temperature. Compare the middle of three seasons when planning your garden.
Geometric daylight estimate from latitude and solar declination, rounded to 0.1 hour. This is time above a flat horizon, excluding atmospheric refraction, hills, buildings and cloud cover. It is not the direct-sun exposure of your bed. About solar-position calculations.

Distances use GeoNames representative postal coordinates, which may be estimated; they are not driving distances. Nearby areas often share one NASA POWER grid cell, so identical climate values are expected. Differences shown here describe the climate grids, not a measured difference between individual gardens.
Regional advice
Choose a local planting window.
University of Wisconsin Extension
State Extension referral; ask for county-specific vegetable guidance.
Ask which dates refer to indoor seed starting, direct sowing or transplanting, and whether they cover spring or fall. This referral is not a verified postal-code planting calendar.
Find an official community climate stationThe growing checklist
Give broccoli a considered start.
Check new transplants for moisture and leave space according to the variety label. Record whether you sowed seed or set out a plant so later observations have context.
- Choose seed or a transplant. Direct sowing, indoor seed starting and setting out a seedling are different operations. Confirm which one the local calendar describes.
- Sow or harden off. Follow crop and variety guidance for seed depth, spacing and temperature. Harden off nursery-grown seedlings before setting them outdoors.
- Check spring and fall timing. Use separate local guidance for each season. Heat and the time left for the crop to mature matter alongside cold tolerance.
Inspect soil moisture and drainage in the actual bed; rainfall normals cannot tell you whether roots need water today.
These are general growing stages, not local planting dates. Minnesota calendar dates are not transferred to other regions. Read the Extension guide to growing stages.
