10/10 · 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 — 05:00–08:00 (dawn bite) and 19:00–22:00 (dusk bite).

Tactics

Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.

Lures

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

Gear

Pack transitional-season clothing — mornings and evenings are chilly.

Summary

Worth going — it's a productive day.

How this forecast is calculated

Why this forecast

The computed water temperature is around 9 °C — inside the 1–10 °C comfort range for Arctic char, so baseline activity is high.

Arctic char 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 Arctic char feeds0:0012:0024:00

Pressure is dropping 2 hPa over the day — fish are usually more active ahead of a weather change.

Pressure through the day, 2 hPa change
00:00 · 101823:00 · 1016 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.
