🌊 Biggest flood tides at SAN Juan this month: Sep 3, Sep 4, Sep 5, Sep 6, Sep 7, Sep 8, Sep 28, Sep 29, Sep 30. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.

🔻 Negative (minus) low tides at SAN Juan this month: Sep 5, Sep 6. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
