Plan the best tide & moon windows
- •Low tides open wide sand at Stinson, Bolinas, and Richardson Bay — pair with sunrise for photos.
- •High tides can cover beach access paths; check times before hauling kayaks or paddleboards.
- •Negative low tides expose tide pools near Duxbury Reef and Agate Beach — go at slack low, not mid-change.
- •Golden Gate reference tides apply across central Marin; west Marin lagoons can lag 15–30 minutes.
- •Share today's tide card with friends planning the same beach walk or oyster run.
- •Dark-sky window: crescent moons set early — great for stargazing on Marin ridges.
- •Thin crescents near the horizon make dramatic photos with foreground hills or water.
