This market will resolve to "Yes" if the water level at NOAA CO-OPS station 9410230 (La Jolla, CA) is equal to or greater than the listed value, in feet above Mean Lower Low Water, at any six-minute observation between 12:00 AM PT on October 1, 2026 and 11:59 PM PT on March 31, 2027. Otherwise, this market will resolve to "No". Mean Lower Low Water for this market is the tidal datum published for station 9410230 on the 1983-2001 National Tidal Datum Epoch, equal to 4.37 feet above station datum. A subsequent change to the National Tidal Datum Epoch will not change the values used. Only six-minute water levels that NOAA CO-OPS has marked verified are used. On the resolution source page these are the values in the "Verified (ft)" column; values in the "Preliminary (ft)" and "Predicted (ft)" columns will not be considered for resolution. In the CO-OPS API the equivalent is a Quality field of "v". Values are compared as published, without rounding. CO-OPS verifies each month of data during the following month, so an observation that meets the listed value will not resolve this market until it has been verified. A verified observation is used regardless of any quality-control flag NOAA CO-OPS attaches to it. The value as first published as verified governs. A revision published after that will not be considered for resolution, except where the correction provision below applies. … (condensed)
