Summer along the Grand Strand is one of the most exciting times of year. Families flock to Myrtle Beach and Murrells Inlet for sunshine, beaches, boating, fishing, dolphin cruises, and unforgettable days on the water. However, with temperatures climbing into the 90s and the heat index often soaring well above 100°F, it’s more important than ever to make heat safety part of your vacation plans.

The good news? You don’t have to stay indoors to stay safe. With a little preparation, you can still enjoy everything the South Carolina coast has to offer—including spending time on the water with Crazy Sister Marina.

Why Does the Heat Feel So Much Worse?

If you’ve noticed that it feels hotter than the thermometer says, you’re not imagining it. The heat index combines the air temperature with humidity to determine what it actually feels like outside.

Along the South Carolina coast, humidity levels remain high throughout the summer, making it harder for your body to cool itself through sweating. This means even a 92°F afternoon can feel like 105°F or higher.

For visitors who aren’t used to the coastal climate, the heat can become dangerous much faster than expected.

Signs of Heat Exhaustion to Watch For

Whether you’re walking the boardwalk, relaxing on the beach, or heading out on a fishing charter, recognize the early warning signs of heat-related illness.

Symptoms include:

• Heavy sweating
• Dizziness or lightheadedness
• Muscle cramps
• Headache
• Nausea
• Weakness or fatigue
• Cool, clammy skin
• Fast heartbeat

If someone stops sweating, becomes confused, or loses consciousness, seek emergency medical help immediately, as these may be signs of heat stroke.

10 Tips for Staying Safe in the Summer Heat

1. Drink Water Before You’re Thirsty

One of the biggest mistakes vacationers make is waiting until they’re thirsty.

Drink water throughout the day—even before heading outside. If you’re spending several hours in the sun, alternate water with electrolyte drinks to replace minerals lost through sweating.

2. Schedule Outdoor Activities Earlier or Later

The hottest part of the day is usually between 11 a.m. and 4 p.m.

If possible:

• Book morning fishing trips.
• Take an evening dolphin cruise.
• Enjoy sunset boat rides.
• Visit attractions later in the day.

These times are often cooler and can provide some of the best scenery.

3. Dress for the Weather

Choose:

• Light-colored clothing
• Loose-fitting fabrics
• Moisture-wicking shirts
• Wide-brim hats
• Polarized sunglasses

Don’t forget comfortable sandals or water shoes, as pavement and docks can become extremely hot.

4. Never Skip the Sunscreen

Clouds don’t block UV rays.

Use:

• SPF 30 or higher
• Water-resistant sunscreen
• Reapply every two hours
• Reapply after swimming

Sunburn makes it even harder for your body to regulate its temperature.

5. Take Advantage of the Water

One of the best ways to beat the heat is to spend time on the water.

At Crazy Sister Marina, many adventures allow guests to enjoy refreshing coastal breezes while exploring the beautiful waters of Murrells Inlet.

Popular summer activities include:

• Dolphin Cruises
• Private Fishing Charters
• Head Boat Fishing Trips
• Jet Ski Rentals
• Pontoon Boat Rentals
• Kayaking
• Marsh Eco Tours

Being out on the water often feels significantly cooler than standing on the beach or walking around town.

6. Seek Shade Often

Whether you’re at the beach or onshore, take regular breaks in the shade.

Bring:

• Beach umbrellas
• Pop-up tents
• Cooling towels

Even 15–20 minutes out of direct sunlight can help your body recover.

7. Eat Light Throughout the Day

Heavy meals can leave you feeling sluggish in the heat.

Instead, snack on:

• Fresh fruit
• Watermelon
• Grapes
• Salads
• Lean protein

These foods help keep you hydrated and energized.

8. Protect Children and Older Adults

Young children and seniors are especially vulnerable to heat-related illnesses.

Make sure they:

• Drink plenty of water
• Wear hats
• Take frequent breaks
• Stay cool
• Never remain in parked vehicles

9. Know When to Take a Break

Vacation doesn’t have to mean packing every hour with activities.

If you’re feeling overheated:

• Step inside an air-conditioned building.
• Grab lunch.
• Visit a local shop.
• Relax before heading back outside.

Your body will thank you.

10. Don’t Forget Your Pets

If you’re traveling with your dog:

• Bring fresh water.
• Walk early or late.
• Avoid hot pavement.
• Never leave pets in a parked vehicle.

The pavement can become hot enough to burn paws within seconds.

Why Water Activities Are Perfect During Heat Waves

When temperatures climb, many visitors assume they should cancel outdoor plans. In reality, water-based adventures can be one of the most comfortable ways to enjoy your vacation.

Aboard many of the vessels at Crazy Sister Marina, guests can enjoy:

• Cooling ocean and inlet breezes
• Shaded seating areas
• Open-air views
• Restroom facilities on larger boats
• Refreshments available for purchase on select trips

Whether you’re searching for dolphins, heading offshore to fish, or simply enjoying a scenic cruise through Murrells Inlet, being on the water offers a refreshing escape from the inland heat.

Other Ways to Beat the Heat Around Myrtle Beach

Need to cool off between adventures? Here are a few ideas:

• Visit an indoor attraction during the afternoon.
• Grab a scoop of locally made ice cream.
• Explore waterfront restaurants with covered patios.
• Catch a live show in the evening.
• Watch the sunset along the MarshWalk.
• Spend the evening enjoying fireworks over the water during special summer events.

Planning your day around the weather can help you experience more while staying comfortable.
