Spring is in full swing along the Grand Strand by April, bringing warmer temperatures, longer days, and more opportunities to enjoy the outdoors. If you’re planning a Myrtle Beach vacation, understanding the typical weather conditions this time of year can help you pack smart and plan activities that make the most of your trip.

Here’s what tourists can expect from April weather in the Myrtle Beach and Murrells Inlet area.

Pleasant Spring Temperatures

April sees a noticeable warm-up compared to early spring. Average daytime highs reach about 70°F–75°F, while overnight lows settle near 58°F.
 These mild, comfortable temperatures are ideal for sightseeing, golfing, waterfront dining, and exploring coastal communities without the intense heat of summer.

With the warmer air arriving, visitors often find it comfortable enough for light beachwear during the day — though evenings may still call for a light jacket.

Ocean & Beach Conditions

The Atlantic begins warming in April, with ocean temperatures averaging around 64°F (18°C).
 That’s still cool for extended swimming for many visitors, but it’s suitable for wading, shoreline walks, shell hunting, or short dips depending on your tolerance. Some long-term averages also place April water temperatures in the low-to-mid-60s°F range.

Even if swimming isn’t the main focus, beach time is enjoyable thanks to increasing sunshine and milder air temperatures.

Sunshine, Daylight & Rainfall

April brings longer, brighter days across the Grand Strand:

  • About 13 hours of daylight daily 
  • Nearly 10 hours of sunshine on average 
  • Around 2 inches of rainfall over roughly 12 days 

Most rain comes in passing showers rather than full washout days, and extended sunny stretches are common.
 Importantly for travelers, April falls outside the Atlantic hurricane season, reducing the risk of major storms impacting vacation plans.

Humidity, UV & Coastal Comfort

Humidity levels average about 76%, giving April a slightly more coastal feel as summer approaches.
 The UV index averages around 5, meaning sun protection like hats and sunscreen is recommended during midday outdoor activities.

Gentle ocean breezes help balance the warmth, making the climate comfortable for extended time outside.

Why April Is Great for Coastal Adventures

April hits a sweet spot between cooler off-season travel and peak summer crowds. Visitors can enjoy:

This makes it an excellent time to get out on the water with Crazy Sister Marina, where guests can experience the coastal environment firsthand — spotting wildlife, enjoying scenic views, or simply soaking in springtime along the South Carolina coast before peak tourist season arrives.

Packing Tips for April Visitors

To stay comfortable throughout your trip, consider bringing:

  • Light clothing for warm afternoons 
  • A jacket or sweater for evenings 
  • Sunscreen and sunglasses 
  • Comfortable walking or boating shoes 
  • Swimwear (for pools or brief ocean dips) 

Layering continues to be helpful, as spring weather can vary throughout the day.
