Issued: 4:00 AM Jul. 8, 2026 – National Weather Service
...COASTAL FLOOD ADVISORY IN EFFECT FROM 4 PM THURSDAY JULY 9 TO
4 AM PDT THURSDAY JULY 16...

7/9, 1.2 ft above normal (7.0 ft MLLW) at 8:17 PM 7/10, 1.5 ft
above normal (7.3 ft MLLW) at 9:11 PM 7/11, 1.7 ft above normal
(7.5 ft MLLW) at 10:06 PM 7/12, 1.7 ft above normal (7.5 ft

roughly 3-6 inches of additional water mainly from a combination
of thermal expansion and accumulated sea level rise since the

90 minutes earlier or later along the Pacific Coast and through
the San Francisco Bay, respectively.
