The USDA Plant Hardiness Zone Map puts Tulelake in Zone 6b (-5 to 0°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

Zone 6b around Tulelake has about 2 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 06/06 isn't a guarantee

06/06 is the middle of 30 years of NOAA records, not a promise. Plant by 05/18 and you're betting against frost in roughly 9 years out of 10. 06/23 is the safer bet, historically only a 1-in-10 chance of frost that late.
