Biggest Waves in San Diego On Record
Below, find a list of a few notable times when some of the biggest waves in San Diego throttled our coastlines.
- Big Wednesday December 2005
This was a notorious day in San Diego and throughout all of Southern California and Baja California. Wave heights crested 3-4x overhead with top breaks like La Jolla Cove and Blacks Beach peaking at 20 feet plus. Check a video of the action at Black’s here –
2. September 2004
Surprisingly, some of the biggest waves recorded to hit San Diego were from a South swell. Waves maxed out in the 15-20 foot range. Check photos of the action here.
3. January 2012
In summary, these are just a few of the days on record for the biggest waves in San Diego. Waves will be even larger in places like Cortes Bank, but that wave is about 100 miles off the coast of San Diego.
What Causes Ocean Swell?
Ocean swell is caused by wind. However, there are two main classifications of swell: windswell and groundswell. While both swell types are caused by wind, they are characterized differently.
Windswell: Windswell originates closer to shore. As such, the swell period is shorter, the waves are usually messier, and have a short period, i.e., waves come to shore quickly.
Groundswell: Groundswell originates far offshore, sometimes thousands of miles. Winds generate swell that builds over time over long distances. Groundswell is typically more powerful, cleaner, and longer period, i.e., a longer interval in between set waves. Groundswell is more common for producing big waves.
As you can see, windswell and groundswell are different. However, both types of swell are created when wind blows across the water creating friction. This energy is then transferred from the wind to the water and fuels the formation of waves.
