The year, day by day
The calendar barely moves in Waimanalo Exp F: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 65°F near January 16 and 85°F near September 5.
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 65°F around January 16.
Where the wet dates fall
The likeliest wet date is December 13, when 59% of years recorded at least a hundredth of an inch. The driest is June 2 at 35%. Summed across the calendar, that is about 170 wet dates a year.
The widest day
January 16 carries the biggest normal gap between afternoon and dawn, 14°F between the normal high and the normal low.

Where Waimanalo Exp F Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 14°F.
Waimanalo Exp F earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Waimanalo Exp F spreads its precipitation across the year
Neither half of the year dominates here: June through August take 12% of the annual total and December through February 35%, with neither reaching the 35% that would mark a distinct wet season. Waimanalo Exp F has no dry season to plan around, though it does carry an unusually narrow 8.2°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 5.5" and June 1.3". The three wettest months together take 38% 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.
How Waimanalo Exp F's precipitation splits across the calendar
About 169 days a year record measurable precipitation here, carrying 42.4" between them, or roughly 0.25 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
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.
Waimanalo Exp F'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 Waimanalo Exp F's climate pattern fits together
cooling led · moderate · low swing
Warm-season load persists through a relatively even calendar in Waimanalo Exp F. Cooling totals 3,962 degree days, more than double the 1 heating measure, and the 8.2°F seasonal range is compact rather than sharply divided.
Waimanalo Exp F's 42.4 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 8.2°F band across the normal year. August and January mark the typical warm and cold ends of the calendar. The annual average is 76°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 Waimanalo Exp F. 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 Waimanalo Exp F'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 Waimanalo Exp F 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 Waimanalo Exp F's primary station: WAIMANALO EXP F 795.1 (USC00519523). 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 Waimanalo Exp F; 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 Waimanalo Exp F comes from its primary NOAA station record.
