Wind Swell vs Groundswell: Tell Them Apart by Period

Under 10 seconds is wind swell: choppy, weak, quick to fade. Past 12 seconds is groundswell: long lines and real push. How to read which one is arriving.

Read height, period, wind, tide, and direction together.

What Is the Best Tide for Surfing?

Most beach breaks work best at mid-tide on an incoming (rising) tide. Low tide exposes sandbars and reefs, creating hollow fast waves. High tide floods the bottom contour, producing slower mushy waves. Every break has a preferred tidal window. NWS tide predictions are accurate to the minute.

How Big Is 3 ft Surf? Face Height vs Hawaiian Scale

A 3-5 ft forecast is significant wave height. Faces run 1.5-2x that, so 4.5-10 ft; Hawaiian scale calls the same wave half. Know which you're reading.

How Does Swell Direction Affect Surf at Your Beach?

Swell direction is the compass heading waves arrive from — 300 degrees means northwest. Every beach has a swell window determined by its coastline orientation and exposure. A 45-degree mismatch between swell direction and beach facing loses 10-15% wave energy. A 90-degree mismatch loses 50-70%.

How Swell Wraps Around a Point

Swell bends as it enters shallower water near a headland. That bending — refraction — is why points like Rincon and Trestles can magnify a small swell from the right direction and ignore a bigger one from the wrong angle. Direction matters more than height at a point.

What Size Surfboard Should I Get?

Beginners: 8-9 foot soft-top foamie with 60-80 liters of volume, roughly 1-3 feet taller than you. Volume determines paddle ease and stability. After 50+ sessions of consistent wave-catching, size down to a 7-foot funboard. Shortboards (5'8"-6'4") are for intermediate surfers with 100+ sessions.

What Are the Rules of Surf Etiquette?

The cardinal rule: the surfer closest to the peak (breaking part of the wave) has priority. Never drop in (take off on someone else's wave). Don't snake (paddle around someone to steal priority). Paddle wide around the lineup. Control your board. Respect locals. These prevent collisions and injuries.

What Is a Beach Break vs Reef Break vs Point Break?

Beach breaks: waves break over shifting sandbars, peaks move around, falls are forgiving. Best for beginners. Reef breaks: waves break over rock or coral, consistent shape, shallow and dangerous. Point breaks: waves peel along a headland or jetty, long rides, consistent direction. Examples: Huntington Beach (beach), Pipeline (reef), Rincon (point).

What Equipment Do I Need to Start Surfing?

Essential gear: soft-top surfboard (8-9 ft foamie, $200-400), leash (6-9 ft matched to board length), wetsuit (thickness matched to water temperature), and wax (temperature-specific). Optional: rash guard, earplugs, reef booties. Total starter budget: $300-600. Skip the shortboard.

What Is a Rip Current and How Do I Escape One?

A rip current is a narrow channel of water flowing from shore back out to sea at 1-8 feet per second. It pulls you OUT, not under. Escape: don't fight it — swim parallel to shore until free of the current, then swim back in. If exhausted, float and signal for help. NOAA reports roughly 100 rip current drownings per year in the US.
