April In Myrtle Beach Actually Isn't What The Brochures Say
April in Myrtle Beach brings a weird transitional window where the weather feels like it can't make up its mind. The tourist boards will sell you on warm sunny days and empty beaches, which is half true. The other half is that the Atlantic is still around 60°F and the mornings feel like late November until mid-afternoon when everything heats up fast. Here's the practical breakdown. Average highs run 70-75°F by mid-to-late April. Lows sit in the upper 50s. Rainfall drops to about 2.5 inches for the month, which is why you see those stretches of clear blue sky. But "clear" doesn't mean predictable. I've seen mornings start at 48°F with fog rolling off the coast, then jump to 78°F by 2pm with zero cloud cover. The temperature swing alone is about 30 degrees, sometimes more. The ocean stays cold into May. Swimming is an option if you don't mind shock, but most people I talk to find it tolerable only after the third afternoon of a trip when they've accepted the situation. Wading in the surf is fine for kids. Jumping in for a lap swim is not. If your trip hinges on daily ocean swimming, late April is the minimum you should book. Early April and you're mostly looking at beach walking and tide pooling.
Crowds are moderate. Not empty, not packed. The spring break rush has cleared but summer families haven't arrived yet. Hotel rates typically sit 30-40% below June pricing. That's the real advantage of April. You get decent weather and you don't pay June prices for it. My rule of thumb: if you're coming for the beach experience specifically, aim for the last two weeks. If you're fine with a mix of beach and indoor activities, the first two weeks work too. One thing nobody warns you about is the wind. Myrtle Beach sits on a barrier island with zero tree cover along most of the shoreline. April winds regularly hit 15-25 mph from the northwest. It makes 72°F feel like 60°F when you're standing on the sand. I learned this the hard way on a 2019 trip when I packed light shirts and shorts assuming the thermometer reading was the actual experience. By day two I was wearing a light windbreaker just to walk the boardwalk. Pack layers. A windbreaker or light jacket is essential even if the forecast says 75. Rain in April tends to be quick and localized. You'll see the radar show scattered cells moving through, but they usually pass in 20-40 minutes. It rarely rains all day. The trick is that when it does rain, the humidity jumps from 50% to 85% in about ten minutes and stays there until the next wind shift. That humidity hit is what makes April feel uncomfortable to people expecting dry warmth. It's not cold, it's just damp and sticky afterward.
Sun protection is still necessary even though the angle of the sun isn't as intense as summer. UV index in April regularly hits 6-7, which is in the high range. I've seen people get burned by noon on a cloudless April day and be confused about how it happened. SPF 30 minimum. Hat. Sunglasses. The kind of stuff you'd pack for July, not skip because it's spring. If you're driving from further north, watch for the ice-over possibility in early April. Cold fronts can push through from the Appalachians and leave a thin glaze on the roads for a morning or two, especially on routes heading east toward the coast. It's rare but it happens. Check the forecast the night before you leave, not just the morning of. Activity-wise, the outdoor attractions start opening for the season in April. Broadway at the Beach and the Myrtle Beach Boardwalk are fully operational. Some of the smaller water parks and arcades along the strip don't open until late April or early May, so verify before you plan your itinerary around them. The golf courses are in their prime condition this month, which is why April is considered peak season for golf traffic here. Expect higher prices at the popular courses even though it's technically shoulder season for lodging.

Dining outdoors is comfortable this month. You won't need heat lamps on the patios. But if your reservation is at a place with open seating and no wind shielding, it can get chilly by 7pm. The sun drops fast off the water. Arrive early for dinner if you want a good table, or just accept that you'll be wearing a light sweater at 8pm when it's still 65 outside. Overall, April works well if you understand what you're getting. It's not beach weather in the traditional sense. It's transition weather. The skies are often clear, the temps climb nicely during the day, and the crowds stay reasonable. Just don't build your entire trip around ocean swimming in early April and pack for a 30-degree daily swing and you'll be fine.
