What Weather to Expect in March on the Grand Strand (Myrtle Beach Travel Guide)
Planning a spring getaway to Myrtle Beach or the Grand Strand? March is a unique time to visit — the winter chill fades, spring energy starts building, and outdoor adventures begin to ramp up. If you’re heading to the coast, here’s a tourist-friendly guide to what kind of weather you can expect and how to make the most of it during your stay.
Mild Spring Temperatures
March signals the transition into spring along South Carolina’s coast. Visitors can typically expect average daytime highs around 62°F (17°C) and nighttime lows near 50°F (10°C), making it comfortable for sightseeing, waterfront dining, and outdoor activities.
Long-term climate data also shows average March highs closer to the upper 60s°F depending on the year, reinforcing the reputation for mild coastal weather compared to colder northern destinations.
While it’s not peak beach-bathing season yet, the moderate temperatures make March ideal for walking the shoreline, exploring marshlands, or enjoying time on the water.
Ocean & Beach Conditions
The Atlantic Ocean is typically at its coldest point of the year in March, averaging about 57–58°F (14°C).
For most visitors, that’s too chilly for extended swimming without gear, but the cooler water doesn’t stop people from enjoying beach views, fishing, shell collecting, or boat excursions.
Sunshine, Daylight & Rainfall
Spring brings more daylight and sunshine to the Grand Strand:
- Around 12 hours of daylight per day on average
- Roughly 7–8 hours of sunshine daily
- About 1.5 inches of rain spread across 13 days
Rain is usually light and intermittent rather than all-day storms, and March falls outside hurricane season, so severe tropical weather is not a typical concern.
Overall, visitors often experience plenty of clear or partly sunny days mixed with occasional passing showers — perfect for flexible vacation planning.
Wind, Humidity & Comfort
Relative humidity averages around 75%, and coastal breezes are common.
These breezes help maintain comfortable conditions and make activities like sightseeing, dolphin watching, and fishing trips especially enjoyable.
Why March Is Great for Coastal Adventures
Because crowds are lighter and temperatures are comfortable, March is a fantastic time to explore beyond the beach towel. This includes:
- Marsh eco tours
- Fishing charters
- Dolphin watching
- Scenic boat rides
- Exploring Murrells Inlet
Experiences like those offered at Crazy Sister Marina give visitors a chance to enjoy the Grand Strand’s natural beauty from the water — whether you’re casting a line, spotting wildlife, or simply soaking in the salt air before the summer rush begins.
Packing Tips for March Visitors
To stay comfortable, bring:
- Light layers or a jacket for cool mornings
- Comfortable walking shoes
- Sunglasses & sunscreen (UV levels are moderate)
- Rain gear just in case
- Closed-toe shoes for boating or dockside exploring
Layering is key — spring weather can shift between sunny warmth and breezy coolness throughout the day.
