Issued 04:38 · Forecaster Mara Venn

The west window opens before the wind does.

A deep Aleutian fetch has tightened overnight. First energy reaches the outer reefs at civil twilight; the inside points wake roughly forty minutes later. The shape is better than the raw height suggests.

02 / WHY PERIOD WINS

Same height. Entirely different ocean.

Six feet is only half a forecast.

Period describes the distance between the ocean’s breaths. Drag the primary-period control above: at 7 seconds, energy arrives in a confused crowd. At 14, the same six feet draws long, separated cords across the horizon and feels the bottom much earlier.

03 / TIDE DESK

Friday · July 10 · Santa Agueda

The reef gets a forty-minute invitation.

Best overlap is the final third of the push: enough water over the west shelf, not enough to soften the bowl. The bureau’s call is wheels rolling at 05:12.

Needs less tide and more luck. Wind chop makes the peaks wander; clean groundswell reveals two reliable A-frames.

Cold lot · dim light · no second trip

Leave before the forecast feels certain.

Pre-dawn competence is mostly preparation. The ocean can stay mysterious; the fin key does not have to.
