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. Not drawn, because no public source places them: Bari Reef.
The coves
Bari Reefnamed this week 40 ft · dock steps at Sand Dollar · the most fish-counted reef in the Caribbean; tanks by the door
1000 Stepsnamed this week 35 ft · 67 limestone steps that feel like 1000 with tanks · elkhorn stands and turtle traffic; the stairs earn the name on exit
The instruments
buoy none, tide station none, water 85F now (the bell wants 62F or warmer).
When it rings: the mornings the trades ease and the lee goes to glass. In its casting against years of this water, 27% of mornings reached 7. Rings since casting: 0.
