Broadhaven Bay (County Mayo) — a popular fishing spot. About 41.2 km² in area. The town of Belmullet is nearby. 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.

    4/10 · Weak

    Hourly activity

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

    The bite is moderate — fish feed in short bursts. 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 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 13 °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 dropping 2 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.

    Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.

    Solunar feeding periods

    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.
