Big Spanish Key is a subordinate station: NOAA computes its tides from Key West with fixed time and height corrections.

Moving water at dawn and dusk —

The current runs fastest roughly halfway between a high and a low tide. Many anglers prefer those hours when they fall near sunrise or sunset. This is a rule of thumb, not a fishing forecast.

Yes — on 176 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -1.0 ft on January 21, 2027 at 7:16 AM. Minus tides expose the most shoreline, which is why tide-poolers look for them.

What time zone are these tide times in?

Station local time (EDT at the time this page was built), with daylight saving time applied where the area observes it — the same convention as NOAA's own tide tables.

Where does this tide data come from?

From NOAA CO-OPS, the U.S. government tide station network (tidesandcurrents.noaa.gov); the predictions are public domain. Big Spanish Key is a subordinate station: NOAA derives its times and heights from the reference station Key West with fixed corrections. The curve between highs and lows is our interpolation.
