๐Ÿงฎ How we score the bite

The 0โ€“10 score adds up five factors: pressure and its stability (up to 3 โ€” sharp jumps suppress fish), moon phase (up to 2), wind (up to 2 โ€” a light ripple beats calm and storm), clouds and precipitation (up to 2), water temperature (up to 1 โ€” each species has its own comfort range). Peaceful fish and predators use different coefficients. It is a computed forecast from weather-station data and our water model, not a guarantee of catch. Updated several times a day.

Fishing bite forecast in Portsmouth โ€” in detail

The bite forecast is computed from real weather data for Portsmouth: atmospheric pressure and its dynamics, wind, cloud cover, precipitation, moon phase and water temperature โ€” Atlantic Ocean. 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) โ€” 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 Portsmouth, the weekly weather forecast and the lunar calendar.
