Hourly activity

Bite activity:highmediumlow

The bite is strong — fish are active. Weather is steady, with no sharp swings — fish behave predictably.

Peak bite hours

Best time — 07:00–09:00 (dawn bite) and 21:00–23:00 (dusk bite).

Tactics

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

Lures

In clear water, natural colors work best: trolling spoon or spinner.

Gear

Bring a warm jacket — it's noticeably colder on the water than on shore.

Summary

Worth going — it's a productive day.

How this forecast is calculated

Why this forecast

The computed water temperature is around 51 °F — inside the 43–59 °F comfort range for Coho salmon, so baseline activity is high.

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 rising 0.21 inHg over the day — the bite usually settles down after a rise.

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.

Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.

Solunar feeding periods

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.
