Port Richey, FL: when does the frost end?

Zone 9b

Typically, the last spring freeze lands around 02/05, roughly 161 days out. Fall's first freeze usually shows up around 01/01, roughly 322 days after the last spring frost.

Port Richey sits in USDA Zone 9b (25 to 30°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

Stretching the season past the first frost

With roughly 18 weeks until Port Richey's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 02/05 isn't a guarantee

02/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/06 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/05 and only about 1 year in 10 sees frost after that.
