Grays Bay (Oregon) — a spot well known among anglers. About 16.8 km² in area. Nearest town — Astoria. A coastal water: the bite here is modelled for the sea, not for a river or a lake. This page shows an hourly bite forecast for today and the week ahead; the algorithm factors in the weather, atmospheric pressure, and the moon phase.

Coho salmon

9/10 · Good

Hourly activity

0:006:0012:0018:0023:00
Bite activity:highmediumlow

The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued.

Peak bite hours

Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).

Tactics

Look for structure — reefs, flats, channel edges; work them slowly near the bottom.

Lures

The water's turning murky — go with bright, noisy lures: trolling spoon or spinner.

Gear

Bring a warm jacket — it's noticeably colder on the water than on shore. Rain is expected — don't forget a rain jacket or a waterproof shell.

Summary

Worth going — it's a productive day.

How this forecast is calculated

Why this forecast

The computed water temperature is around 59 °F — warmer than the 43–59 °F comfort range for Coho salmon: in the heat it drops deeper and feeds less often.

Coho salmon works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.

The day: daylight hours and when Coho salmon feeds0:0012:0024:00

Pressure is dropping 0.06 inHg over the day — fish are usually more active ahead of a weather change.

One more input — the moon's feeding windows: within their hours the score sits higher than across the rest of the day. The window times are in the “Solunar feeding periods” card below.

The windows are set by the moon's transit and rise, and the forecast above already accounts for them: within these hours the bite score sits higher than across the rest of the day, while the day's overall level still comes from the catch-calibrated model.
