The Lowdown
Alright folks, Rusty here. Let’s get into it.
It’s gonna be a bit of a slow burn for the next couple of weeks. The first real standout isn’t until Saturday the 18th, so we’ve got a few flat days to sit through. The water is running much warmer than normal for this time of year, sitting at a balmy 81° with a huge anomaly, so you’ll be ditching the wetsuit for sure.
The best of the bunch, and the one I’m pinning my hopes on, is San Mateo on Saturday morning, July 18th. We’ll see a clean 3ft of swell from the SW with a solid 12-second period and a combined wave energy of (292). The wind is light and cross-offshore, which means the face will be nice and clean. For an inconsistent spot like this, you’ve got to get on it when it comes together. Keep an eye on the crowds though, as it’s known to get busy.
The other good one to circle is Monday morning, July 20th. Again, clean conditions with light cross-offshore wind and a 2ft swell from the WSW. The period is a long 15 seconds, giving it some real punch for a point break, and the energy registers at (289). It’s a bit smaller, but the quality will be there.
After that, things get patchy again. There’s a bit of a tease on the morning of Sunday, July 26th, with a healthy 3ft of SW swell, a very long period of 17 seconds, and massive energy of (614). But the wind is cross-shore, so it’s a marginal one. That long period will make the waves straight at a beach break, but at a point like San Mateo, it could be proper. Might be worth a look, but it’s a long-range call, so keep your expectations tempered.
The rest of the window is mostly a write-off with onshore winds and choppy conditions. There’s a solid run of poor surf from the 13th right through to the 17th, so don’t bother paddling out until Saturday.
Rusty out.

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.
