SwellAngler — What SwellAngler is

SwellAngler is a fishing-conditions and species reference covering Hong Kong, Taiwan, Singapore, Malaysia and the United States. Pick a spot on the map to see local tide, water temperature, wind, wave, pressure and moon phase, combined into a 0–100 fishing score.

How to use it

A fishing app for tide, wind, score and species

SwellAngler is a fishing app that runs in your browser — nothing to download. Pick a spot on the map and you get the tide, water temperature, wind, waves, pressure and moon phase for that point, combined into a 0–100 fishing score. Tide for Hong Kong comes from the official HKO astronomical predictions, and for the US from NOAA; elsewhere it comes from a global model. If you are looking for a fishing tide app, this is exactly what we cover and what we do not: the marine model runs about 10 days out, coastal accuracy is limited, and it must not be used for navigation or safety decisions.

Data sources and disclaimer

The fishing score is a multi-factor reference model. It does not guarantee a catch and must not be used for navigation or weather safety. Tide and wave data come from global numerical models with limited coastal accuracy; check official forecasts before going out.
