Hourly activity

Bite activity:highmediumlow

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

Peak bite hours

Best time — 07:00–09:00 (dawn bite) and 20:00–22:00 (dusk bite).

Tactics

Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots. The water's cold — fish it more delicately and slowly.

Lures

In clear water, natural colors work best: spinner or fly. The water's cold — work the lure slower than usual.

Gear

Bring a warm jacket — it's noticeably colder on the water than on shore.

Summary

Worth going — it's a productive day.

How this forecast is calculated

Why this forecast

The computed water temperature is around 6 °C — colder than the 7–16 °C comfort range for Brook trout: the fish conserves energy and takes more cautiously.

Brook trout 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 Brook trout feeds0:0012:0024:00

Pressure is dropping 5 hPa over the day — fish are usually more active ahead of a weather change.

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.
