A fading SSW groundswell (13–14s @ 205–212°) combos with a building W windswell overnight — Wavecast calls it "chest-high" for Sunday as the Genevieve swell fades. Tippers takes this angle at its prime window with no closeout risk (unlike Ponto's straight bars). Dead calm 5–7am, sea breeze fills ~8am. Tide is a 0.39ft low at 6am, rising through the session. Chris works a 1400 swing shift tomorrow — dawn is hours clear of that.
Data from evening-surf-call run, pulled Sat Aug 1 ~7:00pm PT · buoys + NOAA tides + NWS + Open-Meteo + Wavecast (Thu 7/30 6:00am post, 2 days stale — not a publish day). Surfline not checked (no browser access in automated runs).
Tippers and South Ponto both clear all four factors this swell — optimal S/SSW angle, 13–14s period, calm dawn wind, low-incoming tide — but the tiebreaker (reef over beach break) sends the call to Tippers, and the combo with the building W windswell removes Ponto's usual closeout risk. Windansea scores well on angle/period/wind but is capped at MEH: dawn's 0.39ft low is outside its 2–4ft mid-tide window. Sunset Cliffs is capped at MEH — S is only a marginal angle there and the low tide exposes the ledges. Blacks doesn't qualify: neither swell component clears the canyon-focus window (W/NW ≥13s or S 170–200° ≥14s). Oceanside Harbor sits out — this S/SSW swell mostly passes the NW-facing jetty by.
Days to Watch
Sun Aug 2 — Wavecast: Genevieve swell fades to chest-high today as a light NW windswell fills in, then small/waist-high through Fri Aug 7. Next real building swell (new SW groundswell) isn't expected until ~Aug 8.
