The Lowdown
Alright, let’s talk about what’s coming up, mate.
The first few days are a bit of a dud. Thursday 23rd and Friday 24th are pretty flat and messy, so don’t bother. But things start looking up from Friday morning.
The real sweet spot is Friday 24th, Saturday 25th, and Sunday 26th, all in the mornings. San Mateo is a point break, and it’s inconsistent, but when it’s on, it’s a thing of beauty. Water temp is 81°, which is much warmer than normal for this time of year—a real bonus. On Friday morning, we’ve got a 2ft swell from the SW, with a 21-second period, and the wind is glassy. That’s about as clean as it gets. The wave energy is moderate (736). The swell direction from the SW suits the break’s optimum NW direction, so you’ll get some nice, long rides.
Saturday morning is even better. The swell is 3ft from the SW, period 19 seconds, and again, glassy winds. The energy is moderate (775), and the sky is clear. It’s a beautiful, clean morning. The swell is still small enough for anyone, but the inconsistency means you’ll be waiting for the sets.
Sunday morning holds up with a 4ft SW swell, 17-second period, and glassy wind. The energy is moderate (795). The afternoons get a bit choppy with cross-onshore wind, so hit the early sessions.
From Monday 27th, the swell jumps to 5ft, but the wind goes cross-shore and the conditions get a bit messy. It’s still surfable, but not the perfection of the weekend.
The best of the lot is definitely those three mornings—Friday 24th, Saturday 25th, and Sunday 26th. The swell is small, clean, and the glassy wind makes it a dream. The point break will handle the long-period swell fine. After that, the surf drops off into the second week, with swells around 2ft to 2ft and mostly cross or onshore winds. There’s a tiny blip on Thursday 6th August with a 3ft swell, but the wind is messy, so it’s not worth getting excited about.
Get out there this weekend. The near-term forecast is solid, and the long-range stuff is less certain and not looking as good.

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.
