Model spread is not a confidence interval. Tide and wind are context, not new corrections to surf size. Larger sets and changing hazards remain possible.

This entry is mapped as a searchable surf zone rather than a claim of one frozen takeoff. Expect shifts with sand, tide, swell angle and crowd pressure.

Before paddling out: Currents, crowding, submerged reef or cobble, water-quality changes after rain, and shifting bars.

THE FIELD GUIDE / RAT Beach

Read this stretch of coast.

Follow the swell window

The catalogue’s reported preference for RAT Beach is “W–NW”. Compare that description with each component’s incoming direction and period. An offshore swell number is a reference; the local wave still depends on the actual shoreline, bottom and tide.

Check the water level

Reported tide preference: Low–mid. Follow the named NOAA station and its trend through your intended session, then inspect the entry and exit at the beach. A station prediction is not a water-level sensor at this takeoff.

Read the bottom and the lineup

Catalogue bottom: Sand. Reported difficulty: Intermediate. Watch several sets before choosing where to enter, keep clear of riders, and compare the actual wave with your ability and equipment.

A useful note for next time

Record the section you actually surfed, the time, incoming swell direction and period, wind and tide trend. Add what the wave did: connected sections, closeouts, drift or exposed obstacles. Comparing that observation with the same model next time is more useful than treating one colored number as the whole session.
