The year, day by day
The calendar barely moves in Nettles Island: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 57°F near January 16 and 89°F near August 17.
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 57°F around January 16.
The widest day
January 12 carries the biggest normal gap between afternoon and dawn, 16°F between the normal high and the normal low.

Nettles Island runs a summer-peaked wet season
35% of Nettles Island's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is September at 9.2", on an unusually narrow 17.9°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: September, August, June, taking 41% of the annual total between them.
- Driest month: February at 2.6".
- Winter share: 14% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.

How Nettles Island's climate pattern fits together
cooling led · wet · low swing
Warm-season load persists through a relatively even calendar in Nettles Island. Cooling totals 3,935 degree days, more than double the 198 heating measure, and the 17.9°F seasonal range is compact rather than sharply divided.
Warm-season demand is paired with a wet annual normal: 58.9 inches of precipitation at Nettles Island. Snowfall is not added to the interpretation because its annual value is missing. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.
Nettles Island's 17.9°F seasonal spread is compact even though precipitation is abundant. August and January mark the typical warm and cold ends of the calendar. The annual average is 75°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
A frost-free growing-season length is not available for Nettles Island. 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 Nettles Island'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
- At 83°F (28°C) this is a genuinely hot month, in the top third of US stations, and the daily average understates afternoon highs.
- Coldest normal
- January
- The coldest month still averages 65°F (18°C), above freezing, so this calendar has no hard winter.
- Rainfall rhythm
- September to February
- September is typically wettest; February is driest.
- Mild-temperature window
- January through December
- Monthly means sit between 55°F and 75°F in this window.

Where does this Nettles Island climate data come from? ▼
NOAA U.S. Climate Normals v1.0.1 (1991-2020). Figures on this page come from Nettles Island's primary NOAA station (NETTLES IS, USC00086092).

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.
