The Lowdown

Alright folks, Rusty here. Let's have a look at what San Mateo has in store for us over the next couple of weeks.

First up, the water temp is sitting at 80°, which is a massive 7° warmer than normal for this time of year. That’s very unusual, so you’ll be in for a warm one if you’re paddling out at this spot.

To be straight with you, the next week and a half is a bit of a letdown. From Wednesday the 15th right through to Saturday the 26th of July, the surf is mostly poor. Winds are almost constantly cross or cross-onshore, and the conditions just aren't cooperating. There’s a long stretch here with no real quality windows, just a couple of mornings that are barely marginal, like Saturday the 18th and Monday the 20th, but nothing you'd want to get out of bed early for. The swell is hanging around 1.0 ft to 3 ft, mostly from the SW, but the wind messes it up every time.

Now, let's talk about the light at the end of the tunnel. We’ve got a proper standout showing up on Sunday, July 26th. The morning starts glassy—absolutely dead calm—with a 3 ft SW groundswell rolling in at a long 18 seconds. The energy is moderate at 497. It’s a proper groundswell, so that long period will make for some nice shaped waves, but at a point break like San Mateo, that’s exactly what you want. The only downside is this spot is inconsistent, so you can’t bank on it every time, and crowds are possible. But if it fires, it’ll be worth a look.

Then, just when you think it’s over, Monday, July 27th morning looks even better. Again, glassy conditions—3 mph wind from the SSW, basically nothing. The swell pulses up to 3 ft from the SW with a very long 16-second period, and the energy jumps to a strong 825. This is the best on offer for the whole run. The combination of clean, offshore wind and that long-period groundswell at a point break could be something special. Keep in mind, though, this is over a week away, so the forecast is promising but not set in stone.

After Monday morning, the winds pick back up and we slide back into marginal or poor conditions for the rest of the outlook period, with the swell building to 5 ft by Thursday the 30th, but it’s choppy and cross-onshore.

So, to sum it up: wait it out for that glassy Sunday morning on the 26th, and keep your eyes peeled for Monday the 27th—that’s the real standout. Everything else is a write-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.
