Myrtle Beach Weather: The Ultimate Guide to Planning Your Coastal Getaway
Myrtle Beach, South Carolina, is a crown jewel of the East Coast, attracting millions of visitors annually to its 60-mile stretch of pristine coastline known as the Grand Strand. Understanding the nuances of Myrtle Beach weather is essential for planning the perfect getaway, whether you are chasing summer waves, scheduling a golf retreat, or seeking a quiet winter escape.
Characterized by a humid subtropical climate, this coastal haven offers distinct seasonal transitions, moderate winters, and warm, sun-drenched summers. Below is an authoritative breakdown of what to expect year-round, backed by meteorological data.
Spring Weather (March to May): The Grand Awakening
Spring is widely considered one of the best times to visit Myrtle Beach. As winter chill dissipates, daily highs transition from a comfortable 64°F (18°C) in March to a gorgeous 76°F (24°C) by May.
According to seasonal records from the National Weather Service (NWS) Wilmington Office, spring brings beautiful blooming seasons, though visitors should prepare for occasional brisk coastal breezes.
- What to Pack: Light layers are highly recommended. While afternoons are pleasant enough for shorts and t-shirts, evenings near the shoreline can feel crisp, requiring a light jacket or sweater.
- Water Temperature: Ocean temperatures rise from the low 50s to the mid-60s, making wading popular, though it remains slightly too cool for extended swimming.
Summer Weather (June to August): Peak Beach Season
Summer represents peak tourism season on the Grand Strand. Temperatures consistently hover in the upper 80s to low 90s (approx. 31°C - 34°C). Combined with high humidity levels, the heat index can frequently rise past 100°F.
Fortunately, refreshing ocean breezes offer natural relief near the coast. Ocean water temperatures rise dramatically during these months, peaking near 82°F (28°C) in August, as documented by marine climate trackers at the National Oceanic and Atmospheric Administration (NOAA).
- Afternoon Showers: Visitors should anticipate brief, convective afternoon thunderstorms. They typically pass quickly, but keeping a close eye on local radar is advised.
- What to Pack: Swimwear, high-SPF sunscreen, wide-brimmed hats, and lightweight, breathable fabrics.
Fall Weather (September to November): The Local Favorite
Autumn is a favorite among locals and savvy travelers alike. The intense summer heat mellows into comfortable daytime temperatures ranging from the mid-80s down to the low 70s.
According to the official regional guides at Visit Myrtle Beach, autumn hosts numerous outdoor festivals, car shows, and golf tournaments due to the reliably pleasant and dry conditions.
- Water Temperature: The Atlantic Ocean remains warm enough for swimming well into October, often hovering around 75°F (24°C).

Hurricane Season Considerations
It is critical to note that late summer and autumn coincide with the Atlantic hurricane season, which runs from June 1st to November 30th. Historically, peak activity occurs between late August and October. Travelers visiting during this window should regularly monitor updates from the National Hurricane Center (NHC) and consider travel insurance that covers tropical weather disruptions.
Winter Weather (December to February): The Peaceful Lull
Winter brings a peaceful, low-stress atmosphere to Myrtle Beach. Daytime highs average around 55°F to 60°F (13°C - 16°C), while overnight lows occasionally dip into the high 30s (approx. 3°C - 4°C).
According to comprehensive climate profiles on US Climate Data, snow is exceedingly rare in this region, making Myrtle Beach an attractive winter escape for northern "snowbirds" seeking to escape freezing blizzards.
- Golfers' Paradise: While too cold for swimming, winter is a premier season for golf enthusiasts. The Grand Strand's world-class golf courses remain open, offering competitive off-season rates.
- What to Pack: Medium-weight jackets, windbreakers, and closed-toe shoes to handle the cool ocean winds.
