Beach Safety Tips for a Safe Day at San Diego Beaches

One of the most important beach safety tips is simple: swim near a lifeguard.

Lifeguards train to monitor ocean conditions, identify hazards like rip currents and respond quickly in emergencies. Before entering the water, take a moment to locate the nearest lifeguard tower and check for posted warnings.

You can also check beach conditions before you go. Use tools like Safe Beach Day. It shares safety updates, hazard levels and ocean conditions. Lifeguards and safety groups report this information.

“Lifeguards have real-time knowledge of the water that most people don’t,” says Dr. Schwendig. “If they give instructions or close an area, it’s critical to follow their guidance.”

To stay safe:

• Swim near an open lifeguard tower
• Pay attention to flags, signs and announcements
• Ask questions if you’re unsure about conditions

Rip currents are one of the most dangerous ocean hazards. These fast-moving channels of water can pull swimmers away from shore quickly.

Knowing how to spot them is key. Look for:

• Darker, murky water
• Gaps in breaking waves
• Choppy or foamy areas

If you’re caught in a rip current:

• Stay calm
• Don’t swim against the current
• Swim parallel to shore until you escape
• Signal for help

“Panic is what puts people in danger,” says Dr. Schwendig. “If you stay calm and follow basic rip current safety techniques, your chances of getting out safely are much higher.”

If you see someone struggling, alert a lifeguard immediately rather than attempting to rescue someone on your own.

Spending time at the beach increases your exposure to ultraviolet (UV) rays, which can lead to sunburn and long-term skin damage.

To protect your skin:

• Use a broad-spectrum sunscreen with SPF 30 or higher
• Apply 15 minutes before sun exposure
• Reapply every two hours and after swimming
• Don’t forget areas like ears, feet and lips

“Sunburn is more than a temporary irritation - it’s a major risk factor for skin cancer,” Dr. Schwendig says. “Consistent sunscreen use is one of the most important things you can do for your long-term health.”

Water-resistant sunscreen is especially important for beachgoers, as it maintains protection during swimming and sweating.

Encounters with marine life like stingrays and jellyfish are common at San Diego beaches but are usually preventable.

To avoid stings:

• Shuffle your feet in shallow water to avoid stingrays
• Avoid touching jellyfish, even if they appear dead
• Pay attention to posted warnings about marine life

“Most sting injuries happen when people aren’t aware of their surroundings,” Dr. Schwendig says. “Simple habits, like doing the ‘stingray shuffle,’ can make a big difference.”

If you’re stung:

• For jellyfish: Liberally rinse with seawater, scrape or carefully remove stingers, apply heat as tolerated
• For stingrays: soak the wound in hot water
• Notify a lifeguard for immediate assistance
• Seek medical care if symptoms worsen

Prompt first aid can reduce pain and prevent complications.

Ocean water can contain elevated bacteria levels, especially after rainfall due to runoff.

To reduce your risk:

• Avoid swimming for at least 72 hours after heavy rain
• Check for posted water quality advisories
• Stay out of the water with open cuts or wounds

“Swimming in contaminated water can lead to infections and gastrointestinal illness,” Dr. Schwendig says. “If there are warnings posted, it’s best to wait until conditions improve.”

Spending hours in the sun can lead to dehydration, heat exhaustion or heat stroke.

Watch for symptoms like:

• Dizziness
• Headache
• Nausea
• Fatigue

To stay safe:

• Drink water regularly, even if you’re not thirsty
• Take breaks in the shade
• Limit alcohol, which can worsen dehydration

“Heat-related illness can escalate quickly, especially in children and older adults,” Dr. Schwendig says. "Don’t ignore early symptoms."

Staying hydrated is one of the simplest but most important beach safety tips.

A few simple precautions can help prevent injuries and emergencies:

• Always supervise children near the water
• Swim within your abilities and comfort level
• Be aware of changing weather and surf conditions
• Wear footwear to protect your feet from hot sand or sharp objects
• Avoid alcohol when swimming
• Follow all posted beach rules and closures

Seek medical attention if you experience:

• Difficulty breathing or signs of an allergic reaction
• Severe pain from a sting or injury
• Signs of infection, such as redness, swelling or fever
• Confusion, fainting or symptoms of heat stroke

A safe beach day starts with preparation and awareness. By following these beach safety tips — and listening to lifeguards — you can reduce your risk and focus on enjoying the ocean.

“The beach should be a place to relax,” Dr. Schwendig says. “When you take basic precautions and respect the environment, you can enjoy it safely.”
