What these dates mean in Wyoming

Planting usually runs about 35 days, from Aug 25 to Sep 28.

That start date is about 23 days earlier than the middle of the 42 places in this data set that report winter wheat planting dates (Sep 17).

Harvest usually runs about 41 days, from Jul 13 to Aug 22.

From the start of the planting window to the start of the harvest window is about 322 days in Wyoming, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for Wyoming. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Frost dates and local conditions vary; NASS state-level usual dates from 20-year progress data (Oct 2010 edition), begin ~5% and end ~95% complete. Check your last spring frost and soil temperature, and confirm with your county extension office.
