Hawaii Frost Dates: Last and First Frost by Town
Frost is rare in most of Hawaii: at 48 of its 50 NOAA stations, 32°F nights happen too seldom in 1991–2020 records to compute an average date. Regular frost is limited to 2 stations, mostly at high elevation: Mauna Loa 5 NNE (11,179 ft, last frost April 12), Kanalohuluhulu 1075 (3,600 ft, last frost January 26).

Frequently asked questions
Where does it frost in Hawaii?
Only at 2 NOAA stations out of 50, mostly at high elevation. Mauna Loa 5 NNE (11,179 ft) has a median last frost of April 12 and first frost of December 1; Kanalohuluhulu 1075 (3,600 ft) has a median last frost of January 26 and first frost of January 24.
Does it frost everywhere in Hawaii?
No. At 48 stations in Hawaii, 32°F nights were too rare in 1991–2020 to compute an average frost date, so those places are frost-free in most years.
How to use these dates
Frost dates are 30-year averages from NOAA, not forecasts. Use them to plan seed starting and planting, then watch the 10-day forecast as the date approaches. Cold air settles in valleys and low spots, so a garden at the bottom of a slope can frost a week or more later in spring than the nearest station shows.
Ready to plan? The planting calendar by ZIP code turns these dates into start-indoors, transplant and sowing dates for 30 crops.
Sources and method
Dates are the 32°F freeze probabilities published in the NOAA NCEI 1991–2020 U.S. Climate Normals for each station. Station names are NOAA's, lightly expanded for readability. See the methodology or download the full table.
