Bay Middle Loch (Hawaii) — one of the area's fishing spots. About 3 km² in area. Nearby towns: Waipahu, Pearl City and Aiea. Salt water, not fresh — so this page carries its own marine bite forecast. This page shows an hourly bite forecast for today and the week ahead; the algorithm factors in the weather, atmospheric pressure, and the moon phase.

The shoreline is moderately indented: bays and points alternate with even stretches. Larger than 8 of the 12 waters nearby.
The wind builds its wave along the north-west — south-east axis — 2 mi of open water; along north-east — south-west there is only 1 mi. When it runs down the main axis, the calm water sits against the bank it blows from, while the wave and the silt go to the far one — and the fish follow them there to feed.
Hawaii: the months when each species peaks and when it goes quiet. The current month is outlined.
| Fish | January | February | March | April | May | June | July | August | September | October | November | December |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Cobia | slow | active | peak | peak | active | fair | fair | fair | active | fair | slow | slow |
| Mahi-mahi | slow | slow | fair | active | active | active | active | fair | slow | slow | slow | slow |
Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
Middle Loch — Tuesday, October 20
The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably. Peak 10:00–15:00.
The computed water temperature is around 58 °F — colder than the 68–84 °F comfort range for Cobia: the fish conserves energy and takes more cautiously.
Cobia feeds by day — between sunrise and sunset; their times are in the sun-and-moon card above.
Pressure is dropping 0.03 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.
October is an average month for Cobia here.

Partly cloudy · feels like +66°
The day is 1 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldG1 geomagnetic storm, Kp 4.7
Kp index — NOAA data. Not part of the bite score: catches show no link between geomagnetic storms and the bite.
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.
