Gold Beach Frost Dates and Growing Season
Frost and the growing season
NOAA's 1991-2020 freeze probabilities for Gold Beach RS. 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 February 16 and the first fall freeze around December 16, a growing season of about 314 days.
- Median at 36°F
- last March 29, first November 24
- Median at 32°F
- last February 16, first December 16
- Median at 28°F
- last January 2, first December 29
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.

The chance of an earlier freeze than the date shown. At 10 percent, one fall in ten freezes before the date.

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 0.4 km from Gold Beach. Low ground, valleys and open fields freeze earlier and later than a town center or a hillside.
