The year, day by day
The calendar barely moves in Myrtle Beach: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 33°F near January 17 and 88°F near July 12.
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 33°F around January 17.
The widest day
November 9 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Myrtle Beach Stands Nationally
The normal water year runs well above the national norm at roughly 54 inches.
Myrtle Beach earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Myrtle Beach spreads its precipitation across the year
Neither half of the year dominates here: June through August take 33% of the annual total and December through February 21%, with neither reaching the 35% that would mark a distinct wet season. Myrtle Beach has no dry season to plan around, though it does carry a 35°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 6.8" and November 3.1". 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.

Data-derived climate profile
How Myrtle Beach's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Myrtle Beach averages 53.6 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 Myrtle Beach's middle-range seasonal profile. The measured spread is 35.0°F. The annual average is 62°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Myrtle Beach's normal, at 2,671 and 1,748 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.
A roughly 237-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
These labels group NOAA 1991-2020 normals from Myrtle Beach'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 Myrtle Beach, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
