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. Not drawn, because no public source places them: Point Dume Cove.

The coves

The instruments

buoy 46221, tide station 9410840, water 75F now (the bell wants 62F or warmer).

When it rings: the offshore mornings, when the canyons breathe out to sea. In its casting against years of this water, 23% 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 →
