Canyon Lake, CA 92587 Frost Dates
Canyon Lake, CA: when does the frost end?
The last spring frost here typically falls around 01/28, about 153 days from today. Fall's first freeze usually shows up around 12/18, roughly 329 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Canyon Lake in Zone 9b (25 to 30°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 16 weeks until Canyon Lake's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/28 isn't a guarantee
01/28 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/27 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/24 and only about 1 year in 10 sees frost after that.
