Most Important Rule

Always swim near a lifeguard. They are trained to spot and respond to emergencies. Over 80% of beach rescues happen to swimmers outside lifeguard-protected areas.

Beach Hazards

🌊

Rip Currents

High Risk

Strong, narrow channels of water flowing away from shore. The leading cause of beach rescues and drownings.

Safety Tips

  • Look for choppy, discolored water flowing seaward
  • If caught, stay calm and swim parallel to shore
  • Never fight the current - let it carry you, then swim sideways
  • Raise your hand if you need help - lifeguards watch for this

How to Spot It

Rip currents appear as darker, calmer-looking channels between waves, often with foam or debris flowing seaward.

🪼

Jellyfish

Moderate Risk

Sea nettles and other jellyfish are common in mid-to-late summer. Stings are painful but rarely dangerous.

Safety Tips

  • Watch for purple flag warnings indicating jellyfish present
  • If stung, rinse with seawater (not fresh water)
  • Remove tentacles with a credit card, not bare hands
  • Seek medical help for severe reactions or stings to face/throat

How to Spot It

Sea nettles are pink/brown and can be seen floating in the water. Tentacles trail several feet below the bell.

☀️

Sun Exposure

High Risk

Sunburn and heat exhaustion are extremely common at the shore. UV rays are strongest 10am-4pm.

Safety Tips

  • Apply SPF 30+ sunscreen 15 minutes before sun exposure
  • Reapply every 2 hours and after swimming
  • Seek shade during peak hours (10am-4pm)
  • Stay hydrated - drink water regularly, limit alcohol

How to Spot It

Signs of heat exhaustion: heavy sweating, weakness, cold/clammy skin, nausea. Get to shade and hydrate immediately.

🏊

Swimming Conditions

Variable Risk

Ocean conditions change daily based on tides, weather, and currents. Always check flags before entering.

Safety Tips

  • Green flag = calm, Yellow = moderate, Red = high hazard
  • Never swim alone or outside guarded areas
  • Children should always be within arm's reach
  • Respect posted warnings and lifeguard instructions

How to Spot It

Check the surf report and flag conditions at beach entrances. Conditions can change throughout the day.

Beach Flag System

Flags are posted at beach entrances and lifeguard stands. Conditions can change throughout the day, so check flags before each swim.

Green

Low hazard, calm conditions. Swimming is generally safe.

Yellow

Moderate hazard. Medium surf and/or currents present.

Red

High hazard. Strong currents, rough surf. May prohibit swimming.

Purple

Dangerous marine life (jellyfish, stingrays) in the water.

Double red flags or a closed beach sign means no swimming allowed.

Seasonal Hazards

Beach conditions and hazards vary throughout the year. Here's what to expect each season.

Late May - June

  • Cold water (60-65°F) can cause shock
  • Variable weather
  • Limited lifeguard coverage early

Water is still cold from winter. Hypothermia risk is higher. Lifeguards may only be present on weekends until mid-June.

July - August

  • Peak jellyfish season
  • Crowded beaches
  • Intense sun/UV
  • Afternoon thunderstorms

Highest risk for sunburn and jellyfish stings. Stay hydrated and reapply sunscreen frequently. Watch for storm clouds.

September

  • Hurricane season swells
  • Reduced lifeguard hours
  • Jellyfish still present

Tropical systems can create dangerous surf even when storms are far offshore. Check conditions before swimming.

Off-Season

  • No lifeguards
  • Cold water temperatures
  • Hypothermia risk
  • Unpredictable conditions

Swimming is not recommended. If walking on jetties or near water, be aware of "sneaker waves" that can knock you down.

Keeping Kids Safe

Children are at higher risk in the ocean due to their size and swimming ability. Follow these guidelines to keep young swimmers safe.

Arm's Reach Rule

Children under 8 should always be within arm's reach of an adult in the water.

Buddy System

Kids should never swim alone. Pair them with a sibling or friend and an adult supervisor.

Identify Landmarks

Pick a landmark (lifeguard stand, umbrella) so kids can find you if separated.

Teach Flag Colors

Make sure kids understand green, yellow, red, and purple flags before entering the water.

Practice Floating

Teach kids to float on their back if tired. This conserves energy while waiting for help.

Rip Current Drill

Practice "swim sideways" so it becomes instinctive. Make it a game before the real beach trip.

Basic First Aid

Know how to respond to common beach injuries. For serious injuries, always call 911.

Jellyfish Sting
  1. Exit the water
  2. Rinse with seawater (NOT fresh water)
  3. Remove visible tentacles with credit card or tweezers
  4. Apply vinegar if available
  5. Use hydrocortisone cream for itching
  6. Seek help if difficulty breathing or severe swelling
Sunburn
  1. Get out of the sun immediately
  2. Cool the skin with damp cloths or cool shower
  3. Apply aloe vera or moisturizer
  4. Take ibuprofen for pain and inflammation
  5. Drink extra water
  6. Seek medical care for blisters covering large areas or fever
Heat Exhaustion
  1. Move to shade or air conditioning
  2. Lie down and elevate legs
  3. Remove excess clothing
  4. Apply cool water to skin
  5. Sip water slowly
  6. Seek medical attention if symptoms worsen or vomiting occurs
Cuts from Shells/Rocks
  1. Rinse wound thoroughly with clean water
  2. Apply pressure to stop bleeding
  3. Clean with antiseptic if available
  4. Cover with bandage
  5. Watch for signs of infection (redness, swelling)
  6. Get tetanus shot if not current and wound is deep

"What If" Scenarios

Know the right response before you need it. These common situations trip up even experienced beachgoers.

🤔You're swimming and suddenly feel pulled away from shore

❌ Wrong Response

Panic and try to swim directly back to shore against the current

✓ Right Response

Stay calm. Swim parallel to the beach (sideways) for 50-100 feet until you escape the rip, then angle back to shore.

Why: Rip currents are narrow. Swimming sideways escapes them quickly. Fighting the current exhausts you.

🤔Your child gets stung by a jellyfish and is crying

❌ Wrong Response

Rinse with fresh water or apply ice directly

✓ Right Response

Exit water, rinse with seawater, scrape off tentacles with a credit card, then seek first aid station.

Why: Fresh water causes stinging cells to fire more. Seawater neutralizes them. Scraping removes them safely.

🤔The lifeguard whistles and points at you

❌ Wrong Response

Ignore it - you're a good swimmer

✓ Right Response

Immediately look at where they're pointing and move in that direction or exit the water.

Why: Lifeguards see hazards you can't (rip currents, marine life, other swimmers). They're trying to protect you.

🤔Afternoon thunderstorm is approaching with dark clouds

❌ Wrong Response

Stay on the beach - it might pass

✓ Right Response

Exit immediately when you hear thunder or see lightning. Get to a building or vehicle.

Why: Lightning can strike 10+ miles from a storm. Beaches are the most dangerous place during lightning.

⛈️ Post-Storm Beach Safety

Beaches can be dangerous for 24-48 hours after storms. Here's what to watch for.

HazardRisk LevelWhat to Know
Rip CurrentsHighStorms dramatically increase rip current strength. Avoid swimming 24-48 hours after storms pass.
Debris in WaterModerateStorms wash wood, glass, and sharp objects into the surf. Wear water shoes. Shuffle feet to avoid cuts.
Bacteria LevelsModerateStormwater runoff raises bacteria levels. Check beach advisories before swimming after heavy rain.
Beach ErosionModerateStorms can create sudden drop-offs. Enter water slowly and be aware of changing depths.
Jellyfish Wash-upModerateStorms push jellyfish onto beaches. Watch where you step. Dead jellyfish can still sting.

Safety by Time of Day

Risks change throughout the day. Plan your swimming around these patterns.

Early Morning (6-9am)

Usually not on duty

Hazards

No rescue available, cooler water

💡 Best for walking, not swimming. If you swim, stay in shallow water and never alone.

Mid-Morning (9-11am)

On duty (usually from 10am)

Hazards

Building crowds, UV increasing

💡 Best swimming time. Fewer crowds than afternoon. Apply first sunscreen now.

Midday (11am-2pm)

On duty

Hazards

Peak UV, heat exhaustion risk, crowds

💡 Take shade breaks. Reapply sunscreen. Stay hydrated. This is peak sunburn risk.

Afternoon (2-5pm)

On duty

Hazards

Thunderstorm risk, tired swimmers

💡 Watch for storm clouds. Afternoon storms are common in summer. Fatigue causes accidents.

Evening (5pm+)

Often off duty by 5-6pm

Hazards

No rescue, reduced visibility

💡 Check if guards are still on duty. Great for beach walks, not recommended for swimming.

Common Beach Safety Mistakes

❌ Turning your back on the ocean

✓ Always face the waves. "Sneaker waves" can knock you down unexpectedly.

❌ Swimming right after eating

✓ Not actually dangerous, but heavy meals can cause discomfort. Light snacks are fine.

❌ Diving headfirst into waves

✓ Shallow water and shifting sand cause neck injuries. Always enter feet-first.

❌ Relying on floaties for kids

✓ Inflatable toys can drift. Kids need adult supervision AND floatation devices certified as life jackets.

❌ Drinking alcohol and swimming

✓ Alcohol impairs judgment, balance, and swimming ability. Most drowning victims have alcohol in their system.

❌ Not telling anyone where you're going

✓ Always let someone know your beach plans. In emergencies, rescuers need to know where to look.
