Amarillo, TX 79110 Frost Dates
Amarillo, TX: when does the frost end?
The last spring frost here typically falls around 04/13, about 228 days from today. Fall's first freeze usually shows up around 10/27, roughly 195 days after the last spring frost.

Stretching the season past the first frost
With roughly 9 weeks until Amarillo's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
04/13 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/29 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/29 and only about 1 year in 10 sees frost after that.
