Your seasonal context
Understand the place before the date.
The 48426 area uses a representative location near 43.477°, -83.064°. In the nearby historical climate grid, July is the warmest month on average (21.6°C), while January is the coolest (-5.6°C). May has the highest mean daily precipitation (2.94 mm).
Monthly mean temperatures are below freezing in January, February, December. Outdoor planting during those months needs a separate protected-growing assessment. 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 43.477° 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.
The 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 a variety suited to your available space and compare its days to maturity with local seasonal guidance.
- Decide whether you are sowing seed or setting out a transplant; these are different starting stages.
- Check the variety’s temperature guidance. Cold tolerance does not mean every seedling survives a freeze.
- Inspect soil moisture and drainage in the actual bed. Regional rainfall averages cannot tell you whether roots need water today.

One small next step
Make a date to check your garden.
Choose your own reminder date after checking local advice. This is a personal planning prompt, not a calculated planting recommendation.
