San Antonio Fishing Forecast

Best time to fish San Antonio

No tide inland — go by heat and water. Mornings and the spring-fed rivers are the only comfortable options in July and August, and the first cool front in October opens the trails back up.

On any given day, the windows above are the honest answer: they weight the solunar periods (moon overhead and underfoot), first and last light, and they subtract for wind that makes the water unfishable and for lightning. A slow day still shows its best hour or two, because that’s when you’d go.

How the rating works

Every day gets a 0–100 score from the same data the rest of Salty Forecast runs on: wind carries the most weight (32%), because it decides whether you can even fish, then sky, barometer and moon phase — there’s no tide to score on fresh water, so those weights are redistributed rather than counted as zero. A falling barometer ahead of a front scores high; a hard post-frontal rise scores low. Nothing here is a black box — the factor bars above show exactly what helped and what hurt.

Generic solunar calculators give San Antonio the same “activity” times as a lake in Ohio, because they only look at the moon. The moon matters — it’s in here — but a 20 mph wind beats it every time, and that’s why this score reads the whole picture.

Common questions

Is today a good day to fish San Antonio?

The live rating refreshes every half hour on this page and on the San Antonio dashboard — wind, sky and barometer scored 0–100.

What time should I fish San Antonio today?

First light, last light, and the solunar periods (moon overhead or underfoot) are the reliable windows on this water.

How is this different from a solunar calendar?

Solunar tables only track the moon, so every town gets the same "activity" times. This rating starts with what actually cancels trips — wind and lightning — then adds barometric trend and the moon. When a day scores Prime here, it means the whole picture lines up, not just the calendar.
