Moss Beach, San Mateo County, California. Its own tide, water, and roads come first, and every reading is dated and linked back to whoever published it.
Only the handful of changes that decide a day, and only for the town you have picked. No account. As a notification, we keep which of these you ticked and your town, and nothing else about you. By email, we keep the address too, only to send these, and every email has a one-click unsubscribe that deletes it. Privacy

Public-safety and marine radio from this county that somebody is streaming online, with what each feed carries.
Nothing streamed here is a police channel for this coast. The Sheriff answers for Montara, Moss Beach, El Granada, Princeton, San Gregorio and Pescadero, and for Half Moon Bay by contract; Pacifica runs its own department. Neither is on any feed in this county — the three police feeds that exist are Menlo Park, Redwood City and South San Francisco, all on the bay side of the ridge. What you can hear from here is fire and the water. Start with the county fire feed.
Run by volunteers, not by any agency. They play an ad first, run a minute or so behind the radio, and can go quiet without notice; Broadcastify’s page for each one shows whether it is on. Not a way to get help: call 911.
