Best time to fish Key Biscayne
Bonefish push onto the flats on the rising tide; a calm, clear morning is worth more than any tide stage.
On any given day, the windows above are the honest answer: they weight moving water first — the middle hours of a falling or incoming tide — then 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 tide movement (26%), seas at the nearest offshore buoy (12%), and sky, barometer and moon phase (10% each). 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 Key Biscayne 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 or 4-foot seas beats it every time, and that’s why this score reads the whole picture.

- Is today a good day to fish Key Biscayne?
- Today rates 84/100 (prime). Go — 9 mph S, 2 ft tide falling through sunrise, 1.1 ft seas, falling barometer. This updates through the day as the forecast models refresh.
- What time should I fish Key Biscayne today?
- Today's best windows are 4–8 AM (falling tide + moon overhead or underfoot) and 10 AM–1 PM (incoming tide + moonrise/set) and 4–8 PM (falling tide + moon overhead or underfoot). Moving water is the biggest single factor — the middle of a tide swing beats slack water almost everywhere.
- What's the best day to fish Key Biscayne this week?
- Today looks strongest at 84/100 (prime) — 9 mph S, 2 ft tide falling through sunrise, 1.1 ft seas, falling barometer. The week-ahead table above updates as the outlook firms up.
- 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, seas and lightning — then adds real NOAA tide movement, barometric trend and the moon. When a day scores Prime here, it means the whole picture lines up, not just the calendar.
