Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Right off the bat, I gotta be straight with you—this isn't a classic run of form for the place. The swell is hanging around, but the wind is just not playing ball most of the time. We’ve got a whole lot of “marginal” and “poor” flags in the data, so we’re mostly looking at a waiting game for those clean windows.
The opening session on Sunday, July 5th, is a bit of a reality check. We’re seeing a 2 ft SW swell with a very long period of 21 seconds, but it’s hitting with a cross-onshore breeze. The combined energy is moderate (841), but that wind is going to chop it up. The water is a balmy 80°, which is much warmer than normal for this time of year, so that’s a nice bonus. But honestly, the waves aren't clean enough to get excited about.
Monday the 6th through the rest of that first week looks pretty frustrating. The swell sticks around—3 ft to 5 ft from the SW, with periods mostly in the 16 to 18-second range, which is proper groundswell. The energy bumps up to a strong 1279 on Monday afternoon. But here’s the kicker: the wind is consistently cross or cross-onshore. It’s gonna be bumpy and choppy, and the reports are flagging it as a write-off. You might get a slightly better look on Tuesday morning with a lighter cross-shore, but it’s still marginal.
We hit a real low point on Friday, July 10th. The morning drops to a tiny 2 ft with a weak period of 5 seconds and the combined energy is a measly 28. That’s a dead zone.
The real standout, the one you want to circle on the calendar, is Monday morning, July 13th. For the first time, we get a glassy window. The wind is from the WSW at just 3 mph, and the report says “glassy.” The swell is a clean 3 ft from the SW with a period of 13 seconds. The energy is moderate (311). This is your best shot for some clean, workable waves. It’s an inconsistent break, so don’t expect a packed lineup, but if you’re there when it’s glassy, you’ll be happy.
The other one to keep an eye on is Tuesday morning, July 14th. It’s not glassy, but we get a light cross-offshore breeze from the south at 6 mph, which means the face will be clean. The swell is 3 ft, SW, with a 14-second period. That’s a solid combo for a point break.
After that, it’s another stretch of onshore wind and chop. The next silver lining pops up on Thursday morning, July 16th. We get another glassy session with a WNW wind at 3 mph. The swell is a bit bigger at 4 ft from the SW, 14-second period, and the energy is moderate (468). That’s a good session for a confident surfer, but it’s over a week away, so don’t lock in your plans just yet.
The second week is a blur of cross and cross-onshore winds, with the swell bouncing between 2 ft and 3 ft. The periods drop off a bit, too. There’s nothing else that screams “go time.” It’s a tough outlook overall, but those two glassy mornings on the 13th and 16th are the real bright spots.
Rusty, signing off.

Information about the San Mateo Surf forecast
The above surf forecast table for San Mateo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at San Mateo can be found by selecting the local surf guide option on the grey menu. Our San Mateo 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 (San Mateo) 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 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. 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.
