McFarland, CA: when does the frost end?
The last spring frost here typically falls around 01/31, about 156 days from today. Fall's first freeze usually shows up around 12/08, roughly 309 days after the last spring frost.

Stretching the season past the first frost
With roughly 15 weeks until McFarland's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/31 isn't a guarantee
01/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/30 and only about 1 year in 10 sees frost after that.
