The Lowdown
Alright, folks, Rusty here. Let's talk about what's cooking at San Mateo.
Alright, let's be real for a sec. The next week and a half is a bit of a write-off. We're looking at a long stretch of nothing special, with a few tiny windows that might be worth a paddle if you're desperate. The water is running at a toasty 80°F, which is a massive 8°F warmer than normal for this time of year – that's very unusual, so you can leave the wetsuit at home.
The first real glimmer of hope comes on Thursday morning, September 3rd. The wind is forecast to be glassy, which is a massive positive, and we'll see a 4ft swell rolling in from the southwest with a long 19-second period. That's proper groundswell energy, and the combined energy reading is a solid 798. This is a point break, so that long-period swell should wrap in nicely. This is the standout of the whole outlook, no question. It’s a point break, so it’s best for advanced surfers, especially with that size. It's inconsistent here, so don't expect a wave every minute, but when they come, they'll be worth it. Crowds are sometimes an issue, so get in early.
The following days show a bit more size. Friday, September 4th, has a 5ft swell from the southwest, period 16 seconds, and combined energy over 1200, but the wind is cross-shore, making for a lumpy surface. It's a step down in quality from that Thursday morning. Saturday, September 5th, drops a touch in size to 4ft, and the wind stays messy. The surf picks up again into the second week, with Tuesday, September 8th showing a promising 5ft swell from the SW with an 18-second period and a huge combined energy of 1576. But again, the wind is cross-shore, and the conditions are rated as marginal. That's a long-range call, so keep an eye on it, but it's promising.
So, to sum it up: the first week is a bust. The only real standout is that glassy Thursday morning, September 3rd. If you can't make that, the following week offers more size but less quality, with Tuesday the 8th looking like the next best bet from a distance.

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.
