Zone 10a (30 to 35°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 Tampa, not a forecast for this year.
What to do before the first frost
Zone 10a around Tampa has about 20 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 01/20 isn't a guarantee
01/20 is the middle of 30 years of NOAA records, not a promise. Plant by 02/10 and you're betting against frost in roughly 9 years out of 10. 12/27 is the safer bet, historically only a 1-in-10 chance of frost that late.
