Atlantic salmon

6/10 · Fair

Hourly activity

0:006:0012:0018:0023:00
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 — 07:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).

Tactics

Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.

Lures

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

Gear

No special gear needed — seasonal clothing will do. 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 16 °C — warmer than the 4–14 °C 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 flat: it moves no more than 1 hPa over the day, so the weather isn't shifting today's bite.

Pressure through the day, 1 hPa change
00:00 · 101723:00 · 1018 hPa

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.
