"King tides return to Southern California coastlines Thursday and Friday, reaching heights 1 to 2 feet higher than normal ocean swells. The National Weather Service warns of hazardous swimming conditions, powerful rip currents and waves up to 7.8 feet in some areas through Saturday. Scientists and coastal planners are using these extreme tides to study future sea level rise and identify vulnerable communities for infrastructure planning."
"The natural phenomenon is predicted to take place on Thursday and Friday and again on Jan. 2 and 3. The National Weather Service warned California beachgoers on to stay out of the water due to hazardous swimming conditions as rip currents can pull swimmers and surfers out to sea. They also advised staying off rocks: "Rock jetties can be deadly in such conditions.""
"By 2050, the median sea level on the California coast is expected to rise as much as 1.2 feet and, by 2100, as much as 6.6 feet. Climate change is playing a big role in this shift as a high concentration of carbon dioxide (caused by the burning of fossil fuels) traps heat, melting land-based glaciers and ice sheets into the ocean."
Perigean spring tides, or king tides, will raise Southern California coastal waters 1 to 2 feet above normal on Thursday and Friday and again Jan. 2-3. The National Weather Service warns of hazardous swimming conditions, powerful rip currents, and waves up to 7.8 feet through Saturday, and advises staying off rocks and jetties. These extreme high tides result from alignment of the sun, moon and Earth increasing gravitational pull. By 2050 median sea level on the California coast could rise about 1.2 feet and by 2100 about 6.6 feet. Planners and scientists use king tides to identify flood-prone areas and guide infrastructure decisions.
