More filled fish = stronger estimated solunar activity. Empty fish on a day card mean no suggested window, not that fish are absent.
Major periods cover one hour before and after the Moon’s upper or lower transit. Minor periods cover 30 minutes before and after moonrise or moonset. The fish meter shows three filled fish for a major period, two for a minor period and one outside those periods. Empty fish on a day card mean no daytime solunar and favorable-weather overlap; missing activity data has no meter. These traditional solunar windows are timing estimates, not measured fish activity or a guarantee of catches. Outside a window does not mean fish will not bite.
Suggestions show overlaps of at least 15 minutes between a solunar period, daylight and Osaka’s favorable hourly weather rating. Mild, poor, missing and outdated weather are excluded. Pressure, sea temperature and moon phase are shown for context; they do not add an unvalidated catch score. Species and local habitat still matter.
Lunar windows are calculated locally for the forecast point using Astronomy Engine. Sunrise, sunset, moonrise and moonset also use this calculation to keep daylight and lunar timings consistent. Moon phase and illumination, pressure and sea temperature come from World Weather Online. All times use the forecast location’s timezone.
Forecast data: World Weather Online. Forecasts are estimates; check official warnings before going out. Do not rely on this forecast alone for navigation or safety decisions.
Your internet address is used to estimate your location through GeoJS (MaxMind GeoLite data). It may be inaccurate, especially on mobile networks or VPNs. Device location is requested automatically when the forecast starts. If it is unavailable or permission is denied, a saved place or approximate internet location is used. Your browser asks permission; GPS availability and accuracy depend on your device. Device coordinates are kept only for this visit, not saved in browser storage. The map loads tiles for the displayed area from OpenStreetMap. When device location is available, rounded coordinates are also used for an OpenStreetMap neighborhood or city lookup. Area names are approximate and may differ near neighborhood boundaries. You can always select a city instead.
Nearby visitors share an area forecast, refreshed when visited. Coastal points are approximate and tide times can differ along the coast. Shoreline distances use a generalized coastline map and are rounded; small islands and local details may be missing. Coastline reference: Natural Earth, public domain.
