Bay Bristol Channel (Devon) — a popular fishing spot. About 5077.6 km² in area. This is a sea water — its bite forecast is a marine one, computed apart from rivers and lakes. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.

Hourly activity

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

The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably.

Peak bite hours

Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).

Tactics

Look for structure — reefs, flats, channel edges; work them slowly near the bottom.

Lures

The water's turning murky — go with bright, noisy lures: pirk or lugworm bottom rig.

Gear

Pack transitional-season clothing — mornings and evenings are chilly. Rain is expected — don't forget a rain jacket or a waterproof shell.

Summary

An average day — best chances during peak windows.

How this forecast is calculated

Why this forecast

The computed water temperature is around 14 °C — warmer than the 4–12 °C comfort range for Atlantic cod: in the heat it drops deeper and feeds less often.

Atlantic cod 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 Atlantic cod feeds0:0012:0024:00

Pressure is flat: it moves no more than 1 hPa over the day, so the weather isn't shifting today's bite.

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.
