Zone 8b (15 to 20°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 Presidio, not a forecast for this year.
What to do before the first frost
About 12 weeks of growing season left in Presidio before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/06 isn't a guarantee
03/06 is the middle of 30 years of NOAA records, not a promise. Plant by 02/14 and you're betting against frost in roughly 9 years out of 10. 03/28 is the safer bet, historically only a 1-in-10 chance of frost that late.
