The Lowdown
Alright, let’s get into this one. Looking at the next sixteen days, we’ve got a pretty quiet stretch ahead with a lot of waiting. The surf doesn’t start showing anything worth the paddle for a few days, and even when it arrives, it’s going to be small or tricky.
There’s really nothing worth chasing until Tuesday, July 21st at 15th Street. The swell is small, around 3 feet, from the SSW with a long 16-second period. That long period means some push, but on a beach and reef setup, it can close out or offer reform waves depending on the tide. The water temperature is really warm, about 74°, which is a good 7° above the norm for this time of year—feels more like a summer pool than the ocean.
Tuesday morning has a light onshore breeze from the WSW at 6 mph. The combined swell energy is moderate at 744. It isn’t a world-beater, but it is the most rideable slot we have. After that, the quality drops.
The next best look comes around Friday, July 25th and Saturday. Swell stays small, around 3 to 3 feet, but the period is long, in the 21-24 second range. Winds are light cross-onshore from the SW at around 6 mph, creating a bit of texture, but Saturday morning particularly could offer some fun little rides for loggers or beginners. The energy jumps to 1046 on Saturday morning, which is moderate-strong. Nothing amazing, but not a total write-off.
The best size appears later, on Friday, July 31st. The swell increases to about 6 feet from the S, with a 14-second period. Combined energy jumps to 1215, and winds are light offshore from the W at 9 mph. That combination, for the experienced crowd, might actually be the highlight. It is still described as marginal in quality, but it is the biggest, most powerful swell of the outlook.
After that, we fade fast. By the start of August, waves drop to 2 to 2 feet, and the wind goes cross-shore or onshore. A long run of poor surf kicks in from August 2nd onward.
So the two standouts are Tuesday, July 21st morning for the cleanest small waves, and Friday, July 31st afternoon for the biggest, cleanest swell if you can handle overhead surf. Outside of that, you are waiting a lot. This kind of quiet stretch is normal around here, so don’t lose hope—things can change fast.

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 15th Street 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.
