Planting without a frost date
Frost-based calendars do not work well here. In mild-winter places the limit is summer heat, not cold: tomatoes and peppers stop setting fruit when nights stay above the mid 70s, and lettuce bolts.
The usual pattern is two seasons. Warm-season crops go in late winter and again in late summer, and cool-season crops like lettuce, broccoli and carrots grow through fall and winter. Your county extension office publishes a local calendar.
Frost probabilities
The station records no 32°F night in at least half of years, so NOAA publishes no frost dates for it.
Where these numbers come from
NOAA station Ewa Kalaeloa Airport (USW00022551) sits 1.6 miles from the center of Kapolei at 54 feet. Its averages cover 1991 to 2020. Low spots, valleys and open fields can keep getting frost a week or two after the station stops; city centers and lakeshores usually get less of it.
Questions
Does Kapolei get frost?
Rarely. The nearest NOAA station records a 32°F night in fewer than half of years, so most winters pass without a freeze.
When should I plant tomatoes in Kapolei?
Without a frost date to work from, timing follows heat instead of cold. Spring and fall are the usual tomato seasons; midsummer heat stops fruit from setting.
