What is a bite calendar?

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 20:00–21:00 (dusk bite).

Tactics

Pick a stretch of steady current, chum one spot and fish it — don't move around without reason.

Lures

Today's bait — jig fly with bloodworm or small fly.

Gear

No special gear needed — seasonal clothing will do.

Summary

Worth going — it's a productive day.

Why this forecast

The computed water temperature is around 16 °C — warmer than the 2–14 °C comfort range for Whitefish: in the heat it drops deeper and feeds less often.

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.
