Lavaca Bay (Texas) — one of the area's fishing spots. About 161.4 km² in area. The town of Port Lavaca is nearby. Salt water, not fresh — so this page carries its own marine bite forecast. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.

    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 — 00:00–04:00 (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

    Worth going — it's a productive day.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 84 °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 dropping 0.12 inHg 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.
