The Lowdown
Alright, Rusty here. Let’s have a look at the forecast for San Mateo.
The next 16 days are a slow burn, but there is one standout that’s worth planning for. Right now, the early part of the week is a bit of a write-off, with small swell and tricky onshore winds. We’ve got a few days of poor conditions to get through before the magic window.
On Tuesday morning, July 21st, there’s a small 3ft SW swell (13 seconds) coming through, but it’s cross-shore wind and the wave energy is moderate (444). The water is a very unusual 81°, which is over 4 degrees warmer than normal for this time of year. The surf is marginal though, and Tuesday afternoon turns choppy and messy. Wednesday and Thursday are pretty much the same story – small, weak swells, and onshore winds. From Friday, July 24th, the swell bumps up a notch, but the wind is still cross-on, so the surf is poor.
The real standout comes on Sunday, July 26th. The morning is absolute glass. We’re talking a 4ft SW swell (17 seconds) rolling in with zero wind. The energy is strong (903). This is your window for clean, lined-up waves at San Mateo. It’s inconsistent, but when it comes, it’ll be worth it. The afternoon goes back to choppy, so get in early.
Monday, July 27th, keeps the energy up but the wind swings cross-off in the morning, offering up clean 4ft SW swell (18 seconds) with strong energy (1193). That’s another good session. The swell pushes into the 5ft range by the afternoon, but it gets a bit lumpy. Tuesday, July 28th, holds 5ft SW swell (16 seconds) – that’s getting into expert territory if you’re not comfortable. The morning is light cross-shore, decent, but the afternoon turns choppy.
The swell drops again mid-week, with Wednesday and Thursday mornings offering clean windows with light offshore winds, but the swell is smaller. After that, we’re looking at poor conditions through to the end of the first week of August. There’s a tiny glimmer on Wednesday, August 5th, with a glassy 3ft SW swell (12 seconds), but it’s very small.
So, the best on offer is Sunday, July 26th, morning, and Monday, July 27th, morning. They’re the only real standouts in this 16-day run. Crowds are sometimes a factor here, so factor that in for the clean windows.
Rusty.

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.
