Bay Inner Harbor (Massachusetts) — one of the area's fishing spots. About 7 ha in area. Salt water, not fresh — so this page carries its own marine bite forecast. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.

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 — 06:00–08:00 (dawn bite) and 18:00–21:00 (dusk bite).

Tactics

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

Lures

In clear water, natural colors work best: salmon spoon or salmon fly.

Gear

It's a hot day — a hat, sunglasses, and plenty of water are a must.

Summary

Worth going — it's a productive day.

How this forecast is calculated

Why this forecast

The computed water temperature is around 70 °F — warmer than the 39–57 °F comfort range for Atlantic salmon: in the heat it drops deeper and feeds less often.

Atlantic 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 Atlantic salmon feeds0:0012:0024:00

Pressure is dropping 0.41 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.

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.
