The year, day by day
The calendar barely moves in Kii-kahuku: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 66°F near January 22 and 83°F near September 19.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 66°F around January 22.
Where the wet dates fall
The likeliest wet date is July 10, when 60% of years recorded at least a hundredth of an inch. The driest is January 21 at 44%. Summed across the calendar, that is about 192 wet dates a year.
The widest day
January 18 carries the biggest normal gap between afternoon and dawn, 11°F between the normal high and the normal low.

Where Kii-kahuku Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 11°F.
Kii-kahuku earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Kii-kahuku spreads its precipitation across the year
Neither half of the year dominates here: June through August take 16% of the annual total and December through February 31%, with neither reaching the 35% that would mark a distinct wet season. Kii-kahuku has no dry season to plan around, though it does carry an unusually narrow 7.6°F seasonal spread.
The gap between the wettest and driest month still matters: November averages 4.0" and June 1.5". The three wettest months together take 36% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
Rain reaches Kii-kahuku in small, frequent amounts
Kii-kahuku records about 192 days with measurable precipitation a year and 32.6" in total, which works out to roughly 0.17 inches on an average wet day. Precipitation on 52% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: July, about 18 of them.
- Fewest: February, about 13.
- Average depth per wet day: 0.17 inches.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Kii-kahuku's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Kii-kahuku's climate pattern fits together
cooling led · moderate · low swing
Warm-season load persists through a relatively even calendar in Kii-kahuku. Cooling totals 3,688 degree days, more than double the 1 heating measure, and the 7.6°F seasonal range is compact rather than sharply divided.
Kii-kahuku's 32.6 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
Temperature varies within a narrow 7.6°F band across the normal year. August and February mark the typical warm and cold ends of the calendar. The annual average is 75°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
A frost-free growing-season length is not available for Kii-kahuku. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
These labels group NOAA 1991-2020 normals from Kii-kahuku's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Kii-kahuku that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Kii-kahuku's primary station: KII-KAHUKU 911 (USC00514500). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Kii-kahuku; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Kii-kahuku comes from its primary NOAA station record.
