Fishing bite forecast in Lisburn — in detail
The bite forecast is computed from real weather data for Lisburn: atmospheric pressure and its dynamics, wind, cloud cover, precipitation, moon phase and water temperature — Celtic Sea. Each species gets its own score: for peaceful sea species (horse mackerel, mackerel, flounder, mullet) comfortable water temperature and steady pressure matter most, for predators (cod) — light, waves and season. The score is recomputed with every weather update, so morning and evening forecasts may differ.
It is a computed model, not a guarantee of catch: local terrain, groundbait and skill matter no less than weather. See also water temperature in Lisburn, the weekly weather forecast and the lunar calendar.
