Pick a county
North to south, 19 of 19 live. Each one opens its board and every town on it.
Every town
Straight to a town's own page.
What a board covers
The same readings on every county and town page.
Every morning
Tides for the nearest station, the Coast Guard bar report where there is one, the marine zone forecast, the land forecast and hourly.
On the road
Caltrans lane closures and highway cameras on the roads that reach the town, CAL FIRE incidents nearby and the county’s burn status, air quality from the nearest monitor.
And the rest
CDPH shellfish advisories, CDFW fishing seasons, beach water where the county samples it, USGS earthquakes near the coast, NTWC tsunami status.
Every reading dated
Each carries when the agency published it and when the board last checked, and a link to the source. Stale readings say so.
