The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, it’s a pretty flat run for a while. The first recommendation doesn’t even pop up until Tuesday, August 18th, and even then it’s a real marginal affair. The surf is small and the conditions are tricky, so you’ll need to be patient. There’s a bit of a gap of quiet days after that, too.
The only break on the radar is Bolsa Chica. It’s a beginner-friendly spot, fairly consistent, but it’s exposed to the SW swell. The water is sitting at a touch warmer than normal at 70°, which is about a degree and a half above the usual for this time of year.
Let’s start with the first decent window. On Tuesday morning, August 18th, the swell is a tiny 2 feet from the SSW with a very long period of 16 seconds. That’s groundswell energy, but it’s weak, with a combined energy of only 311. The wind is light and onshore, so it’s not going to be great. The best call is the Tuesday morning session, but it’s still a “marginal” call, with a score of 1 out of 10. The morning is the only time to look, as the afternoon turns into a cross-onshore chop.
The next slight pulse comes in on Wednesday morning, August 19th, with a similar 3 feet SSW swell and a 15-second period. The wind is a light onshore breeze, so it’s still a bit bumpy. Again, a 1 out of 10 score. The energy is a little higher at 328, but it’s still not enough to get excited about.
Things get a bit more interesting on Saturday, August 29th. The morning shows a 3 feet SSW swell with a 16-second period and a combined energy of 473. The wind is light onshore, and the forecast is still “marginal” for the morning. The afternoon is a write-off.
Then, on Sunday, August 30th, the morning offers a 3 feet SSW swell, also with a 15-second period. The energy is 461, and the wind is light onshore. It’s the biggest swell of the whole period, but it’s still only a 1 out of 10 in the morning. The afternoon is poor.
So, the standout? There’s not a true standout. If I had to pick one, it would be the Sunday morning, August 30th at Bolsa Chica. That 3 feet SSW swell is the biggest, and with a light onshore breeze, it’s the best of a bad bunch. The long period (15-16 seconds) means the waves will have some shape, but at a beach break like Bolsa Chica, it might break a bit too straight. Still, for a beginner, it’s a window.
The second week is a similar story. On Wednesday morning, September 2nd, there’s a 2 feet SW swell with a 16-second period, but the wind is cross-shore, making for a bit of chop. Still just a 1 out of 10.
Bottom line: it’s a quiet, small-swell period. The water is a touch warm, but the waves are not. Don’t get your hopes up. If you’re desperate, the morning of the 30th of August is the best bet.
Rusty.

Information about the Bolsa Chica Surf forecast
The above surf forecast table for Bolsa Chica provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bolsa Chica can be found by selecting the local surf guide option on the grey menu. Our Bolsa Chica surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Bolsa Chica) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Bolsa Chica may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
