Shaded: the span between the dates frost passes in 9 of 10 years and 1 of 10 years[2][3]. Green: planting windows from the CSU rules applied to the median last frost (GardenFacts calculation)[6]. Exact dates are in the tables below.

NOAA records from 1991 to 2020 at the Albany Airport station give the odds[5]. In 9 of 10 years the last spring frost comes after April 16, in half of years after April 27, and in 1 of 10 years after May 11[2]. In the fall, the first frost comes before October 3 in 1 of 10 years, before October 15 in half of years, and before November 1 in 9 of 10 years[3]. These are chances from past years, not a forecast, so any year can come earlier or later[2][3].

  • Hard freeze (28°F): median last spring date April 16, median first fall date October 28[7].
  • Frost-free growing season: at least 150 days in 9 of 10 years, 169 days in half of years and 191 days in 1 of 10 years[4].

When to plant vegetables

Colorado State University Extension's planting guide was written for Colorado[6]. GardenFacts uses the NOAA median last frost date, April 27, as the average last frost[6]. Hardy vegetables such as broccoli, lettuce, peas and spinach can go in as early as 2 to 4 weeks before it, which is March 30 to April 13[6]. Semi-hardy vegetables such as beets, carrots and potatoes can go in as early as 2 weeks before it, which is April 13[9]. Tender vegetables such as snap beans and sweet corn go in from seed around April 27[10]. Very tender vegetables such as tomatoes and peppers typically wait 2 or more weeks after it, so the earliest start is May 11[11].

  • Hardy (broccoli, cabbage, kohlrabi, lettuce, onions, peas, radishes, spinach, turnips): as early as 2 to 4 weeks before the median last frost (April 27) is March 30 to April 13[6]
  • Semi-hardy (beets, carrots, cauliflower, parsnips, potatoes, Swiss chard): as early as 2 weeks before the median last frost (April 27) is April 13, up to the median date itself[9]
  • Tender (snap beans, sweet corn, cucumbers, summer squash): from seed around the median last frost date, April 27[10]
  • Very tender (cantaloupe, eggplant, peppers, tomatoes, winter squash, watermelon): the earliest start, two weeks after the median last frost (April 27), is May 11[11]

Hardiness zone

Zone 6a means the average coldest night of the year is between -10°F and -5°F, averaged over 1991 to 2020[1]. The zone is based on winter lows, not on summer heat or frost dates[14]. All of Albany's land area lies in ZIP code areas rated zone 6a, so the city does not span more than one zone[15].

Zone 6a: average annual extreme minimum temperature -10°F to -5°F (1991 to 2020)[1]. Modeled value at the city center: -8.1°F[1].

Share of the city's land area by ZIP code zone: zone 6a 100%[15].

Frost dates are probabilities from 1991 to 2020 weather records at one NOAA station, not a forecast. Any year can be earlier or later. The hardiness zone describes the average coldest winter night, not frost dates or summer heat. Spots inside the city can differ (ZIP table). Planting rules come from Colorado State University Extension's guide, written for Colorado. A local extension office may give dates tuned to the area. Planting and harvest dates marked GardenFacts calculation are simple arithmetic from the facts above, not advice from the source.
