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.

Know the spot

The northern Jalama peak around the locally named Perch Rock zone.

Also known as North Jalama.

Break type
Beach / rock peak
Wave direction
Left & right
Reported difficulty
Intermediate+
Bottom
Sand, reef & exposed rock
Reported swell preference
W–NW with occasional S wrap
Reported tide preference
Low–mid; bar dependent

More a shifting beach-and-rock setup than one permanent takeoff. It can offer either direction when the bar and swell line up, but the coast is brutally wind-exposed.

Before paddling out: Strong currents, exposed rocks, powerful shorebreak, sharks, cold water and rapid wind changes.

THE FIELD GUIDE / Perch Rock / North Jalama

Read this stretch of coast.

Follow the swell window

The catalogue’s reported preference for Perch Rock / North Jalama is “W–NW with occasional S wrap”. 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; bar dependent. 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, reef & exposed rock. 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.
