The tide
Three days, from the same predictions the forecast reads. Shaded: the dawn and dusk windows.
Water temperature
The weather model's sea-surface temperature: four days past, three ahead (dotted), today marked. Where a pier or NOAA station measures the water, that reading is the card under Right now.
The water, mapped
Gold: the coves the bell names this week. Filled: placed where USGS place names and OpenStreetMap agree; hollow: one source. Blue: the instruments this bell reads, with their distance. The arrow: the week's best swell, arriving from its direction.
The coves
Casino Point Dive Parknamed this week 40 ft · stairs off the breakwater, gear-up benches · kelp cathedral, the wrecks on the sand line; ferry over, walk in
Lover's Covenamed this week 25 ft · cobble beach east of the ferry landing · garibaldi thick as confetti; snorkel-friendly
The instruments
buoy 46221, tide station 9410079, water 75F now (the bell wants 62F or warmer).
When it rings: the island's quiet mornings, in the lee where the channel goes glass. In its casting against years of this water, 34% of mornings reached 7. Rings since casting: 0.

The ledger
This bell has not yet rung. When it does, the ring enters here the moment it is made, and the morning after, the buoy, the wind, the rain and the sky testify to whether it held. Every bell's record →
