Around 01/15 is the usual last spring frost, about 140 days away. Fall's first freeze usually shows up around 12/30, roughly 353 days after the last spring frost.

Stretching the season past the first frost
Corpus Christi's growing season runs out in roughly 18 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 01/15 isn't a guarantee
01/15 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/23 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/11 and only about 1 year in 10 sees frost after that.
