The Lowdown
Alright, let’s talk San Mateo. This spot’s a tricky one – it’s a point break that needs a solid NW swell to really fire, and we’re just not getting that over the next 16 days. The swells are mostly from the SW, which isn’t its happy direction, and the first week is pretty much a dud. Small waves, onshore winds, chop – you’re better off staying home.
But hold on, because there are a couple of windows that could make it worth the wait. The first real standout is Friday morning, July 24. The swell is only 2.6 ft from the SW, but the period is a massive 21 seconds – that’s proper groundswell, and it’ll wrap nicely around the point. Wind is glassy – WNW at 3 mph, so the surface will be like a mirror. Combined energy is moderate at 771, but with that length and zero wind, the waves should be clean and lined up. Keep in mind this break is inconsistent, so these moments are rare. Crowds are possible but not guaranteed.
Then, if you’re patient, there’s another gem on Wednesday morning, July 29. The swell bumps up to 4.3 ft from the SW, period 15 seconds, and again glassy conditions – S at 3 mph. Energy is stronger at 821. That’s a bigger, punchier wave, but still long period, so it’ll offer good shape. This one is further out, so less certain, but worth marking on your calendar.
The rest of the period is mostly marginal or poor. The mornings of July 21 and July 23 have brief clean moments, but the swell is too small to get excited about. Later in the second week, there’s a few more opportunities around July 26 and July 28, but winds turn onshore or cross-shore, spoiling the fun.
Water temp is about average for this time of year, nothing unusual. Overall, it’s a lean spell, but those two glassy mornings – especially

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 San Mateo 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.
