    7/10 · Good

    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 — 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. 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 14 °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 0 hPa over the day, so the weather isn't shifting today's bite.

    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.
