How Apra Harbor, Guam fishes

Open water lies to the east of Apra Harbor, Guam. A wind out of the east is onshore here — it stacks swell and chop into the mouth and pushes stirred-up water inshore, while a west wind flattens the surface and tends to clean it up.

Tide is the clock: moving water pulls bait through the mouth, and the turns around slack are when most of the roster feeds hardest.

Tides here are read from NOAA station 1630000 at 13.4434, 144.6564 — see it on NOAA CO-OPS.
