The Lowdown

Alright folks, Rusty here. Let’s have a proper look at the next couple of weeks for San Mateo. It’s a bit of a mixed bag, to be honest. This point break is a classic, handling a nice NW swell when it gets it, but the next 16 days are going to test your patience.

Right off the bat, the first few days are pretty grim. For Tuesday the 4th and Wednesday the 5th, we’re looking at weak, messy cross-shore winds and small, short-period wave energy. The water temp feels pretty average for this time of year, so no surprises there. The combined energy is weak to moderate at best (141 to 177), and the conditions are mostly poor. Not worth paddling out for any of it.

Thursday the 6th through Friday the 9th is a real dry spell. The swell picks up a bit of energy from the southwest, but those crisp clean windows just aren't there. Most of the mornings have light cross-shore winds with a bit of ripple, and the afternoons are all choppy rubbish. You'd be wasting your time.

Now, Monday the 10th is the true standout in this entire outlook. Monday morning is where it’s at. We’ve got a solid 3 ft swell from the SW, with a long period of 15 seconds. The wind is a light S breeze, giving us a clean, cross-offshore flow. That’s going to produce some real nicely groomed lines peeling down the point. The combined energy is a solid moderate 532, so there's enough push to make it worthwhile. This is your only proper call for the first week – a clean, long-period groundswell that won't be too gnarly for an advanced crew. Crowds are a possibility here, so get out early if you want a quiet session.

After Monday, it’s back to a rough patch. Tuesday the 11th through to the end of that week is more of the same: cross-shore winds, small swell, and poor to marginal conditions. The energy drops right off again.

The next glimmer of hope comes on Saturday the 15th. The morning sees a bigger 4 ft swell from the SW, with 16-second periods. The wind is a light SSW, giving us a gentle cross-shore. It’s not perfect, but with that kind of long-period energy and chest-high waves, it’s going to be a decent option for the more experienced crew. The combined energy is strong at 690, so you'll feel the power. Still, the afternoon gets choppy, so it’s a dawn-patrol mission.

Then on Sunday the 16th, we get another little window. The morning is glassy – dead calm, with a WSW wind. That’s a huge plus. Swell is a more modest 3 ft, but with glassy conditions and a 14-second period, the point will be smooth and tempting. The energy is moderate (393), so it’s a worthwhile chase if you’re keen, though not a bomb. After that, the pattern repeats: small, onshore junk through the end of the run on Wednesday the 19th, which has some moderate energy (725) but messy cross-shore winds.

So, to sum it up: if you can surf, Monday the 10th is the clear winner. Clean, offshore, long-period groundswell. Saturday the 15th and Sunday the 16th are the back-up calls, but they come with a caveat – the 15th has a bit of cross-chop, and the 16th is smaller. Everything else is a write-off. Hang in there.

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.
