Forecast for oyster farms

The water decides. Now you do too.

Tidekeep reads the NOAA tide gauge, the wind on your lease, and the state's shellfish closure map, then returns one number you can act on: the hour the water is safe and legal to harvest, with the harvest tag already written.

Cost of a miss

One missed closure sends a week's harvest back to the bay.

A state closure drops without warning, the map paints orange after dark, and your first sack goes out at 6 a.m. tagged for wholesale. Stopping a harvested lot is how weeks of work gets lost. Tidekeep was built for the 3 a.m. check when nobody is awake but the buoys.

"I checked the state page at 3 a.m. and the map was still orange. That's the whole reason I run Tidekeep now."

How it works

Three gauges in. One window out.

Tidekeep is small on purpose. It watches the three numbers that decide whether your water is harvestable, and it never guesses. No black box, no chat window, just the forecast your lease actually needs.

What Tidekeep returns

05:36 opening low

Fuses the tide curve, wind envelope, and closure status into the single legal slot per day. You get the window, not a dashboard to babysit.

The forecast

A window you can read at 5 a.m.

No three-panel spread of charts. Tidekeep draws tomorrow's tide as one curve, paints the legal band on top of it, and marks the only hours that count. If the curve stays in the band, you work. If it doesn't, you sleep.

  • The legal band is the state's rule, not a Tidekeep opinion
  • The now-line tracks the real clock, tide and closure together
  • Closed sub-windows for wind over your cutoff are marked in advance

Compliance

The harvest tag writes itself.

A shellfish tag lives on every sack that crosses your rail. Tidekeep fills yours from the same feeds it forecasts with, so the paper matches the water and the water matches the map.

  • Lease number, harvest area, and date stamped from your registration
  • Window times pulled from the same forecast you worked
  • Wet weight ready to log out on the rail
