What is a bite calendar?
Rivers

Hourly activity

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

The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite.

Peak bite hours

Best time — 12:00–16:00 (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

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.

Why this forecast

The computed water temperature is around 13 °C — inside the 6–18 °C comfort range for Grayling, so baseline activity is high.
