Humble, TX: when does the frost end?
Around 02/13 is the usual last spring frost, about 169 days away. Fall's first freeze usually shows up around 12/09, roughly 300 days after the last spring frost.

How much risk comes with planting early here
02/13 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/12 and only about 1 year in 10 sees frost after that.
