What is the fishing index based on?

It combines solunar theory — moon phase plus the major and minor feeding windows that track the moon's transit, moonrise and moonset — with local weather factors such as wind, pressure and tide state.

When is the best time to fish at St Clair Beach?

The strongest bites cluster in the major solunar windows, especially where they overlap dawn or dusk. Check today's hourly activity chart and plan to be on the sand an hour before a major window opens.

How is the surf rating calculated?

Each hour is scored on swell height, period and direction, plus wind speed and its state relative to the coast. For curated spots the score is tuned to the break's optimal swell window; otherwise it reflects general conditions.
