A tide gauge has been measuring the ocean off this coast every month for a century. The water is rising, and it is rising faster. Scroll, and read the sea's own ledger.
Since December 1923, a federal tide gauge at Los Angeles Harbor, the nearest century-long station to Laguna, has recorded the mean height of the ocean every month. 1,229 measurements without an editorial opinion among them. This is what a hundred years of the Pacific looks like: not a smooth line but a breathing one, seasons and decades of swell and slack.
The three highest waters in the whole record are the three great El Niño winters. September 2015 is the highest monthly mean ever measured here, 1.13m. October 1997 and September 1983 stand just behind it. Longtime locals remember those winters by what the surf took: sand, stairways, patios, the fronts of things.
El Niño is the ocean rehearsing. Every ratchet upward makes the next rehearsal start from a higher stage.
Underneath the breathing, the trend. Across the full century the gauge rose about 1.1mm a year. Since 1993 the rate is 1.9mm a year, nearly double. The annual mean was 0.77m in 1924 and 0.90m in 2025: about 13cm of ocean that was not there when the plein-air painters set up their easels on the bluffs.
Thirteen centimeters sounds small until you remember that storm surf rides on top of it, every wave, every winter, forever.
This atlas holds 99 places in its beach and surf record: the greeters' corner, the lifeguard headquarters, Brooks Street's surf breaks, the skimboarding birthplace at Aliso, the coves where the art colony learned to see. Laguna's culture was made at the waterline, which is exactly the elevation under negotiation.
The storm ticks below the line are NOAA's coastal-event log for this county, and the busiest year in that log is 2025. The gauge does not predict. It only remembers. So far, everything it remembers is higher than the last thing.
