Arctic char

8/10 · Good

Hourly activity

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

The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued.

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

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 12 °C — warmer than the 1–10 °C comfort range for Arctic char: in the heat it drops deeper and feeds less often.

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 6 hPa over the day — fish are usually more active ahead of a weather change.

Pressure through the day, 6 hPa change
00:00 · 102323:00 · 1017 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.

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.
