The year, day by day

The year in Cedar Island runs from a mild 38°F around January 20 to 93°F at the peak near July 9, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from June 15 through August 28, covering 75 dates. The broader mild season, normal highs of 70°F or more, runs March 20 to November 16.

This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.

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 38°F around January 20.

Where the wet dates fall

The likeliest wet date is August 1, when 44% of years recorded at least a hundredth of an inch. The driest is October 23 at 26%. Summed across the calendar, that is about 124 wet dates a year.

The widest day

February 23 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Cedar Island Stands Nationally

This is one of the wettest normals climates ranked: about 60 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.

Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 75 days a year, more than four out of five ranked stations record.

Cedar Island earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Cedar Island spreads its precipitation across the year

Neither half of the year dominates here: June through August take 32% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Cedar Island has no dry season to plan around, though it does carry a 33.2°F seasonal spread.

The gap between the wettest and driest month still matters: August averages 8.0" and April 3.6". The three wettest months together take 37% 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.

When it rains in Cedar Island, it arrives in quantity

59.5" of precipitation falls across only about 123 wet days here, averaging 0.48 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile

How Cedar Island's climate pattern fits together

mixed demand · wet · mid swing

Water is prominent even though neither heating nor cooling wholly defines the record. Cedar Island averages 59.5 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.

July and January mark the typical warm and cold ends of the calendar in Cedar Island's middle-range seasonal profile. The measured spread is 33.2°F. The annual average is 67°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Cedar Island's normal, at 1,861 and 2,462 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.

The frost-free window extends for about 264 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.

These labels group NOAA 1991-2020 normals from Cedar Island's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Cedar Island, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Cedar Island's climate

How much rain does Cedar Island get?
Cedar Island receives 59.5 inches of precipitation. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Cedar Island get?
Cedar Island averages about 49 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Cedar Island?
Cedar Island has 1,861 heating degree days and 2,462 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Cedar Island's primary station: CEDAR IS (USC00311606). 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 Cedar Island; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
