The Lowdown

Alright, folks. Rusty here.

The only spot worth talking about for the next 16 days is San Mateo. It’s a point break, open to the north-west swell, but it’s an inconsistent one – doesn’t break often, so when it does, it’s special.

We start slow. Tuesday the 28th of July is a total washout. There’s a 5ft south-west swell running with a 16-second period, but it’s cross-onshore and choppy. Don’t bother.

The clear winner is the morning of Wednesday the 29th of July. We’ve got a clean 5ft south-west groundswell, still with that long 16-second period, and the wind is flat calm – glassy conditions. The energy is pumping at (1140). That long period will wrap right into the point, giving you some real quality lines. It’s an advanced break and rarely works, so this is a moment to grab. The water is about average for the season, nothing wild.

After that, the swell fades fast. The rest of the week and into the weekend is a mess of cross and cross-onshore winds, dropping swell, and choppy conditions. By Thursday the 30th, the energy is down to (460) with a 4ft swell, and it just gets uglier.

There’s a dead stretch from Friday the 31st of July all the way to the morning of Thursday the 6th of August. That’s a full week of tiny, wind-blown junk. The energy drops into the double digits.

On the morning of Thursday the 6th of August, it goes glassy again with a tiny 2ft south-west swell, but the period is a solid 14 seconds. The energy is only (154), so it’s small, but it’s clean. A longboard might get you a few little ones.

Then, on the morning of Friday the 7th of August, we get a little bump. The swell hits 3ft from the south-west, period back to 16 seconds, and the energy jumps to (648). The wind is cross, so not perfect, but it’s the best of the second week. The morning of Saturday the 8th of August is similar, with 4ft and 14-second period, but the wind is stronger and cross.

The last week is a total dud. From the 9th of August onward, it’s small, weak, and poor. The 11th and 12th of August show a very long 19-second period, but the swell is only 1ft to 2ft, with energy under 200. Not worth the paddle.

So, to sum it up: the best session is the morning of Wednesday the 29th of July. Glassy, decent swell, and a point that’s set up right. After that, maybe keep an eye on the 7th and 8th of August, but don’t hold your breath.

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.
