The year, day by day
The calendar barely moves in Lanai: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 60°F near January 21 and 84°F near August 11.
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 60°F around January 21.
Where the wet dates fall
The likeliest wet date is January 4, when 20% of years recorded at least a hundredth of an inch. The driest is May 21 at 11%. Summed across the calendar, that is about 55 wet dates a year.
The widest day
April 20 carries the biggest normal gap between afternoon and dawn, 18°F between the normal high and the normal low.

Where Lanai Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 18°F.
A drier-than-most normal water year — around 16 inches, below what four out of five ranked stations collect.

Lanai's wet season runs through the cold months
December, January and February carry 40% of the year's precipitation here, while June through August contribute 13%. 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 7.1°F seasonal spread.
- Wettest month
- January, 2.9"
- Driest month
- August, 0.4"
- Wettest three months
- January, November, December (47% 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.
How Lanai's precipitation splits across the calendar
About 54 days a year record measurable precipitation here, carrying 15.7" between them, or roughly 0.29 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.
Lanai'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 Lanai's climate pattern fits together
cooling led · dry · low swing
Warm-season load persists through a relatively even calendar in Lanai. Cooling totals 2,390 degree days, more than double the 7 heating measure, and the 7.1°F seasonal range is compact rather than sharply divided.
Heat demand sits beside limited local precipitation: Lanai receives 15.7 inches in a normal year, inside PlainClimate's dry range. Recorded annual snowfall is negligible. 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 7.1°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 72°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 Lanai. 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 Lanai's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. They are descriptive ranges, not an official NOAA classification or a forecast for any specific year.
The year in four calendar signals
- Warmest normal
- August
- The month averages 75°F (24°C), a middling summer peak by national standards rather than an extreme one.
- Coldest normal
- January
- The coldest month still averages 68°F (20°C), above freezing, so this calendar has no hard winter.
- Rainfall rhythm
- January to August
- January is typically wettest; August is driest.
- Mild-temperature window
- January through December
- Monthly means sit between 55°F and 75°F in this window.

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. The reproducible method is an exact normalized name-and-state match; unresolved is an upper bound on facilities because spelling variants can be missed.
