Cuero Frost Dates and Growing Season
Frost and the growing season
NOAA's 1991-2020 freeze probabilities for Cuero. 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 2 and the first fall freeze around November 27, a growing season of about 270 days.
- Median at 36°F
- last March 15, first November 12
- Median at 32°F
- last March 2, first November 27
- Median at 28°F
- last February 15, first December 9
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 5.3 km from Cuero. Low ground, valleys and open fields freeze earlier and later than a town center or a hillside.
