The year, day by day
The calendar barely moves in Molokai: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 64°F near January 20 and 87°F near August 27.
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 64°F around January 20.
Where the wet dates fall
The likeliest wet date is November 27, when 37% of years recorded at least a hundredth of an inch. The driest is May 31 at 17%. Summed across the calendar, that is about 106 wet dates a year.
The widest day
January 20 carries the biggest normal gap between afternoon and dawn, 15°F between the normal high and the normal low.

Where Molokai Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 15°F.
Molokai earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Molokai'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 10%. 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 8.4°F seasonal spread.
- Wettest month
- January, 3.6"
- Driest month
- June, 0.6"
- Wettest three months
- January, March, December (44% 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 Molokai's precipitation splits across the calendar
About 106 days a year record measurable precipitation here, carrying 21.7" between them, or roughly 0.21 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.
Molokai'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 Molokai's climate pattern fits together
cooling led · moderate · low swing
Warm-season load persists through a relatively even calendar in Molokai. Cooling totals 3,981 degree days, more than double the 0 heating measure, and the 8.4°F seasonal range is compact rather than sharply divided.
Molokai's 21.7 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 8.4°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 Molokai. 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 Molokai'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 Molokai 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 Molokai's primary station: MOLOKAI AP (USW00022534). 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 Molokai; 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 Molokai comes from its primary NOAA station record.
