Rivers

Hourly activity

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

The bite is strong — fish are active. A thunderstorm is possible: activity rises before the front and drops after.

Peak bite hours

Best time — 11:00–16:00 (daytime activity).

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: fly or small spinner.

Gear

No special gear needed — seasonal clothing will do. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.

Summary

Worth going — it's a productive day.

Why this forecast

The computed water temperature is around 16 °C — inside the 6–18 °C comfort range for Grayling, so baseline activity is high.

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.
