Dumfoundling Bay (Florida) — one of the area's fishing spots. About 1.3 km² in area. Close by — Hollywood, Miramar and Miami Beach. Salt water, not fresh — so this page carries its own marine bite forecast. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.

    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 — 00:00–05:00 (nighttime activity).

    Tactics

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

    Lures

    In clear water, natural colors work best: soft-plastic jig or live bait.

    Gear

    It's a hot day — a hat, sunglasses, and plenty of water are a must.

    Summary

    An average day — best chances during peak windows.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 80 °F — warmer than the 61–79 °F comfort range for Black drum: in the heat it drops deeper and feeds less often.

    Black drum feeds at night: the peak falls in the dark hours, between sunset and sunrise.

    Pressure is flat: it moves no more than 0.03 inHg 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.

    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.
