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 Waimanalo Experiment F 795.1 (USC00519523) sits 4.5 miles from the center of Kailua at 64 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 Kailua 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 Kailua?
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.
