The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for San Mateo.
Right off the bat, I gotta be straight with you – the next week and a bit is pretty grim. We’re looking at a long stretch of mostly poor surf conditions. From Sunday the 2nd all the way through to the middle of the week starting the 11th, it’s a real struggle. The wind is mostly cross or cross-on, and the swell is small and weak. The energy is in the low to moderate range, mostly under 300 (combined energy of all swells directed here), and it’s just not lining up. You’d be fighting a cross-chop for a tiny, weak wave. Not worth paddling out for.
But hold on, because there’s a couple of moments that have my heart racing a little. The real standout is the morning of Friday the 7th of August. This is the one. The wind goes dead calm – glassy as a mirror. We’ve got a 3ft swell from the SW with a very long period of 16 seconds, carrying a good amount of energy (516). That’s a proper groundswell, and for a point break like San Mateo, which is exposed to the NW but is getting SW swell, this could be pure magic. Clean, long lines, and with that period, it’ll have some real push. The water is a very unusual 80°F, which is much warmer than normal for this time of year. Keep in mind it’s inconsistent, so you’ll have to be patient, but when the sets come through, they’ll be worth the wait.
The morning of Monday the 17th of August is another one to circle on the calendar. It’s a long way out, so don’t bank on it, but it’s looking promising. We’ve got a 4ft SW swell with a 17-second period, and the combined energy jumps to 1049 – that’s a strong push. The wind is light from the SSW, so it’ll be cross and clean. For a point break, that long period swell will be great, offering long, powerful walls. It’s a bigger day, so it’ll be for the more experienced crew.
Other than those two mornings, most afternoons are ruined by a moderate cross-onshore breeze, and the mornings are just marginal at best. That first week is a write-off. The morning of Saturday the 15th has a bit of size (3ft) and a decent period (15s), but with a cross wind, it’s just not going to be clean.
So, there you have it. A long wait for a couple of absolute gems. That Friday the 7th is your best bet. Get on it.
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.
