The year, day by day
The year in Fernandina Beach runs from a mild 45°F around January 13 to 91°F at the peak near July 18, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 3 through August 11, covering 40 dates. The broader mild season, normal highs of 70°F or more, runs March 5 to November 25.
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 45°F around January 13.
Where the wet dates fall
The likeliest wet date is September 2, when 43% of years recorded at least a hundredth of an inch. The driest is May 4 at 20%. Summed across the calendar, that is about 114 wet dates a year.
The widest day
January 13 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

Where Fernandina Beach Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 19°F.
The normal water year runs well above the national norm at roughly 50 inches.
Fernandina Beach earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Fernandina Beach spreads its precipitation across the year
Neither half of the year dominates here: June through August take 35% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Fernandina Beach has no dry season to plan around, though it does carry an unusually narrow 27.9°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 7.2" and November 1.9". The three wettest months together take 39% 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 Fernandina Beach, it arrives in quantity
49.9" of precipitation falls across only about 114 wet days here, averaging 0.44 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 114 a year, 31% of all days
- Average depth per wet day
- 0.44 inches
- Most wet days
- August, about 13
- Fewest wet days
- May, about 7
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.
Fernandina Beach'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 Fernandina Beach's climate pattern fits together
cooling led · wet · low swing
Warm-season load persists through a relatively even calendar in Fernandina Beach. Cooling totals 2,918 degree days, more than double the 1,066 heating measure, and the 27.9°F seasonal range is compact rather than sharply divided.
Warm-season demand is paired with a wet annual normal: 49.9 inches of precipitation at Fernandina Beach. Recorded annual snowfall is negligible. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.
Fernandina Beach's 27.9°F seasonal spread is compact even though precipitation is abundant. July and January mark the typical warm and cold ends of the calendar. The annual average is 70°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 Fernandina Beach. 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 Fernandina Beach'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 Fernandina Beach that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.
