The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up at San Mateo.
Right off the bat, it’s a bit of a bummer. The start of this outlook is a write-off. Thursday the 30th and Friday the 31st have some swell on the charts, but the wind is a messy cross-shore, and it's just not coming together. The wave energy is moderate at best, but the conditions are described as marginal to poor, so don’t bother paddling out. We’re looking at a solid gap of a few days where the surf simply isn't worth it.
The first real glimmer of hope comes on the morning of Wednesday, August 12th. This is the standout of the entire forecast. We’re looking at a glassy morning with the wind dying off to almost nothing – that’s a rare treat. The swell is a clean 3 ft from the SW with a very long period of 17 seconds. That long-period groundswell will wrap beautifully into this point break, offering some proper shape and those long lulls between sets. For an advanced spot that’s inconsistent, this is a session to circle on your calendar. The water temp is about average for this time of year, so you’ll be comfortable.
Before that, the morning of Friday, August 7th is worth a mention as a secondary option. The swell picks up to 3 ft from the SW with a very long period of 16 seconds, and the wind is light. It’s not perfect, with a slight cross, but it’s the best the first week has to offer. Expect some fun, clean lines even if it’s a little inconsistent.
After that August 12th morning, the window closes again. The rest of the second week is mostly cross-shore or choppy conditions on small swell. There is a chance on the morning of August 13th, but the wind is slightly onshore, so it’s less appealing.
Overall, don't get too excited for the next week and a half. The 12th of August morning session at San Mateo is the only true standout. It’ll be worth the wait if you can be there.

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.
