Atlantic salmon

5/10 · Fair

Hourly activity

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

The bite is moderate — fish feed in short bursts. A thunderstorm is possible: activity rises before the front and drops after.

Peak bite hours

Best time — 06:00–08:00 (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

Pack transitional-season clothing — mornings and evenings are chilly. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.

Summary

An average day — best chances during peak windows.

How this forecast is calculated

Why this forecast

The computed water temperature is around 12 °C — inside the 4–14 °C comfort range for Atlantic salmon, so baseline activity is high.

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 rising 5 hPa over the day — the bite usually settles down after a rise.

Pressure through the day, 5 hPa 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.
