The forecast tells you what the surf will be like. It doesn't tell you whether you should be in it. Surf safety is mostly common sense plus a handful of specific skills — and the worst incidents happen to people who haven't thought about them in advance. Here's the short list.
Rip currents
The single most common cause of surf-related drownings on US beaches. A rip current is a narrow channel of water flowing seaward, formed by water from breaking waves piling up against the beach and draining back through a low spot in the sandbar. Rips can move at 1–2 m/s — faster than most people can swim.
How to spot one before you paddle out:
- A discolored, often murky channel running perpendicular to the beach.
- A gap in the line of breaking waves — the rip is the path of least resistance, so waves don't break there.
- Foam or debris streaming seaward in a defined line.
- Choppy, agitated water where smooth water surrounds it.
If you get caught in one: don't fight it. Swim parallel to the beach until you're out of the channel, then angle back to shore. Surfers actually use rips deliberately to paddle out faster — knowing them is half the battle.
Leash and board management
Your leash keeps your board with you in a wipeout but turns your board into a missile if it snaps free. Check your leash before every session — frayed cord, weak swivel, cracked plug. Replace anything that looks marginal. Cost: $20. Cost of a loose board hitting another surfer's head: a hospital visit.
If you're a beginner: get a board cover or a soft-top before learning. The fiberglass nose of a shortboard does not care that you just lost your balance.
Lineup etiquette and crowd safety
Most "safety" incidents in crowded lineups are collisions, not drownings. The unwritten rules exist for safety as much as fairness:
- The surfer closer to the peak has priority. Don't drop in on someone already riding.
- Paddling out, don't paddle through the takeoff zone. Go around.
- Hold your board. Don't ditch it if a wave comes and someone is paddling out behind you.
- If you fall, cover your head. Your own board comes back at you.
- Locals aren't required to be friendly, but most are. Watch first, paddle out at the edge, work your way in.
Cold water and hypothermia
Water below ~60°F will sap your strength faster than you think. Below ~50°F, you have minutes before fine motor control goes. Wear the right wetsuit for the temperature:
- ≥ 75°F: boardshorts or rashguard.
- 68–75°F: springsuit or 2 mm top.
- 62–68°F: 3/2 mm fullsuit.
- 55–62°F: 4/3 mm fullsuit + booties.
- 48–55°F: 5/4 mm + booties + hood.
- < 48°F: 5/4/3 mm + booties + hood + gloves.
Wind chill matters too. A 60°F day with 15 mph offshore wind feels much colder than a 60°F day with no wind. Get out before you start shivering uncontrollably — that's the warning sign.
Big surf
"Big" is relative — if you're an intermediate surfer used to chest-high days, head-high surf is your big surf. Don't paddle out into conditions that are 50%+ bigger than your normal session unless you've worked up to it gradually.
For genuine big-wave conditions (overhead+, long-period, hold-downs lasting 15+ seconds), specific safety protocols apply: never surf alone, use the right equipment (gun shape, leash for big waves), know the rescue patterns, and consider whether you've had hold-down training. If you have to ask whether you're ready, you're not.
The big four warning signs to bail
If any of these apply, sit it out:
- You can't keep up with the duck dives — you'll be exhausted before you make it out.
- You're surfing alone and conditions have gotten bigger or stormier than you expected.
- You can't see the bottom (low-vis water + reef = bad math).
- Your hands or feet have gone numb — you've crossed into hypothermia territory.
What this site can and can't tell you
The forecast tells you the size, period, direction, wind, and tide. It doesn't tell you whether your local sandbar is currently shaped for safe takeoffs, whether the lineup is crowded, whether the rip channels have moved since last week, or whether your wetsuit is dry. Make the safety call on the beach, not from the forecast. Watch the lineup for a few minutes before you paddle out. If it doesn't look right, it isn't.
