Last Week of December 2023

It’s officially an El Nino season. The first large swell of winter 2023/2024 blanketed San Diego from North to South throughout the last week of December. This swell peaked December 28th-30th with waves cresting at 10-15ft in standout locations like Black’s. Even La Jolla Cove was breaking, which rarely happens.

Big Swell Carlsbad State Beach 10.13.2021

October is normally a good time of year to be blessed by offshore winds. In this last run of big surf in San Diego, the Santa Ana winds did not disappoint. Overall, the waves were not huge topping out at about head high but it was a clean and glassy more thanks to a light offshore breeze.

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.

  1. 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

Waves as high as 17 feet maxed out in Southern San Diego at places like OB Pier. The pier was closed while surf maxed out. Read the story.

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.
