Kailua Kona Ke-ahole's normals sit in a dry climate class: BWh
Annual precipitation falls well below the aridity threshold for this temperature regime, so the normals classify as hot desert (BWh). Class BWh is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically hot desert.

The year, day by day
The calendar barely moves in Kailua Kona Ke-ahole: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 68°F near February 3 and 87°F near August 12.
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 68°F around February 3.
Where the wet dates fall
The likeliest wet date is May 24, when 18% of years recorded at least a hundredth of an inch. The driest is November 27 at 10%. Summed across the calendar, that is about 50 wet dates a year.
The widest day
February 3 carries the biggest normal gap between afternoon and dawn, 13°F between the normal high and the normal low.

Where Kailua Kona Ke-ahole Stands Nationally
Aridity defines the water calendar: about 10 inches in a normal year lands this among the driest tenth of ranked stations.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 13°F.
Kailua Kona Ke-ahole earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Kailua Kona Ke-ahole's wet season runs through the cold months
December, January and February carry 36% of the year's precipitation here, while June through August contribute 18%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows an unusually narrow 6.5°F seasonal spread.
- Wettest month
- January, 1.4"
- Driest month
- July, 0.5"
- Wettest three months
- January, February, December (36% of the year)
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.
Kailua Kona Ke-ahole is dry, and what does fall arrives gently
Only about 50 days a year record measurable precipitation here, 14% of the calendar, and they carry 9.9" between them. At roughly 0.20 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is May at about 6 wet days; the driest is November at about 3.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

Scarce-water calendar
Where Kailua Kona Ke-ahole's limited precipitation lands
cooling led · dry · low swing
Warm-season load persists through a relatively even calendar in Kailua Kona Ke-ahole. Cooling totals 4,838 degree days, more than double the 0 heating measure, and the 6.5°F seasonal range is compact rather than sharply divided.
Heat demand sits beside limited local precipitation: Kailua Kona Ke-ahole receives 9.9 inches in a normal year, inside PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. Month-level precipitation is the useful check on when that small annual total arrives.
The calendar stays thermally compact and dry. August and January mark the typical warm and cold ends of the calendar, only 6.5°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 78°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
A frost-free growing-season length is not available for Kailua Kona Ke-ahole. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Kailua Kona Ke-ahole's primary station: KAILUA KONA KE-AHOLE AP (USW00021510). 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 Kailua Kona Ke-ahole; 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 Kailua Kona Ke-ahole comes from its primary NOAA station record.
