Maud Frost Dates and Growing Season

NOAA 1991-2020 normals for Wright Patman Dm & Lk, 17.5 km from Maud, elevation 282 ft

Frost and the growing season

NOAA's 1991-2020 freeze probabilities for Wright Patman Dm & Lk. A median date has an even chance of a later freeze in spring, or an earlier one in fall.

The last spring freeze typically comes around March 4 and the first fall freeze around November 21, a growing season of about 261 days.

Last freeze in spring

The chance of a later freeze than the date shown. At 10 percent, one spring in ten still freezes after the date; planting after the 10 percent date for 32°F is the cautious choice.

Growing season length

Days between the last spring and first fall freeze at each threshold, with the chance of a season at least that long.

Degree days

A degree day is one degree of the daily mean temperature beyond a base, for one day. Heating degree days count cold (the fuel a house burns), cooling degree days heat, growing degree days the warmth a crop needs; each crop has its own base.

What this means

NOAA computes these from the daily lows at the station over 1991-2020, fitting the dates of each year's last and first freeze to a distribution, so a date can be stated at any level of risk. 36°F is a frost risk for tender plants on a clear, calm night, since the ground cools below the air above it; 32°F is a freeze; 28°F is a hard freeze that kills most annuals.

The station is 17.5 km from Maud. Low ground, valleys and open fields freeze earlier and later than a town center or a hillside.
