Zone 9b (25 to 30°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Guadalupe, not a forecast for this year.
What to do before the first frost

Why 02/13 isn't a guarantee
02/13 is the middle of 30 years of NOAA records, not a promise. Plant by 01/12 and you're betting against frost in roughly 9 years out of 10. 03/09 is the safer bet, historically only a 1-in-10 chance of frost that late.
