The Lowdown

Rusty here, checkin' in with the surf outlook for San Mateo. It's a point break, and it's an advanced wave, so don't be fooled if it looks mellow—it's fickle and inconsistent, so you gotta be patient. The water is a full 81° right now, which is much warmer than normal for this time of year—like a bath, so you can leave the thick wetsuit at home.

Alright, let's be real. The first few days are a write-off. From Monday the 3rd through to Thursday the 6th, it's all poor surf conditions with tiny, weak swell—mostly under 3 ft from the SW with short periods and cross-onshore winds. The combined energy is weak to moderate (147 to 385), and the wind is just messing it up. Not worth paddling out.

Then we get a sniff of something good. Friday morning, the 7th of August, is your standout. Early doors, it goes glassy—wind is 5 km/h from the West, dead clean. The swell is only 3 ft, but it's a long-period groundswell coming from the SW with a 16-second period. The energy jumps to 516 (moderate). It's not huge, but those long lines will wrap around the point beautifully. This is the best window you'll see for a while. The afternoon turns choppy again, so get in early.

After that, it's back to mediocrity. The weekend and most of the following week are a mixed bag of poor surf conditions and marginal forecasts. The wind stays cross or cross-onshore, keeping things bumpy. The swell ticks up a bit around the 14th and 15th, with the 14th of August Friday afternoon seeing a 5 ft SW swell at 16 seconds and energy hitting 1055 (strong). But the wind is cross and moderate (25 km/h), so it'll be a messy, choppy mess. There's a morning session on the 15th of August Saturday with light cross-shore wind and a 4 ft SW swell, but it's still only marginal.

Later in the window, the 18th of August Tuesday morning shows a 2 ft swell with a 20-second period and 680 energy, but again, it's cross-shore wind and only marginal. The long period means it'll be fat and powerful, but the wind is the enemy here.

Overall, if you're an advanced surfer who's keen on a clean, long-period point wave, get out there on Friday morning the 7th. That's the one. The rest of the 16 days is mostly a waiting game. The swell is there, but the wind just won't play ball. It's a tough stretch for a spot that's already inconsistent.

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.
