Lake Pearl Harbor (Hawaii) — one of the area's fishing spots. About 21.2 km² in area. Close by — Aiea, Waipahu and Pearl City. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.

The shoreline is heavily indented — bays, points and spits. Look for largemouth bass at the mouths of the bays and on the drop-offs behind the points. The islands add structure: drop-offs around their perimeter and channels between them and the bank. The largest water around: all 11 neighbours are smaller.
The longest fetch is 6 mi along the west — east axis: wind along it builds a wave on the open water and pushes silt and food towards the lee bank.
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.
Pearl Harbor — Tuesday, October 20
The bite is strong — fish are active. Weather is steady, with no sharp swings — fish behave predictably. Peak 06:00–08:00 and 18:00–20:00.
The computed water temperature is around 58 °F — inside the 57–75 °F comfort range for Black crappie, so baseline activity is high.
Black crappie works the twilight: the peaks are pinned to 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 active season for Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
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.
