N Myrtle Bch 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 19%, with neither reaching the 35% that would mark a distinct wet season. N Myrtle Bch has no dry season to plan around, though it does carry a 34.4°F seasonal spread.

The gap between the wettest and driest month still matters: September averages 6.7" and April 2.8". The three wettest months together take 38% 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 N Myrtle Bch, it arrives in quantity

48.5" of precipitation falls across only about 122 wet days here, averaging 0.40 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 N Myrtle Bch's climate pattern fits together

mixed demand · wet · mid swing

Water is prominent even though neither heating nor cooling wholly defines the record. N Myrtle Bch averages 48.5 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 N Myrtle Bch's middle-range seasonal profile. The measured spread is 34.4°F. The annual average is 64°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in N Myrtle Bch's normal, at 2,343 and 2,003 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 252 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 N Myrtle Bch'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 N Myrtle Bch, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from N Myrtle Bch's primary station: N MYRTLE BCH AP (USW00093718). 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 N Myrtle Bch; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
