The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s shaping up for San Mateo over the next couple of weeks.
Alright, straight up, this is a tricky one. We’ve got a long, dry spell ahead. The forecast starts with a lot of poor surf conditions and marginal signals, so don’t expect much action for the first week or so. The best window is going to be that Monday the 28th of July, but even then, it’s a bit of a mixed bag.
The first real chance of anything rideable comes on the morning of Saturday the 26th of July. The surf is small, around 4 ft, from the SW. The wind is light and cross-shore, so it’ll be a bit lumpy, but not unmanageable. It’s nothing to get excited about though. The combined energy is a moderate 878 (moderate wave energy), and the period is a middling 17 seconds, so it’s more of a groundswell pulse. Beach breaks might be a bit straight, but for a point like San Mateo, it could offer some shape.
The standout, if you can call it that, looks to be the morning of Monday the 28th of July. We’re looking at 4 ft of SW swell, with a period of 18 seconds, giving a combined energy of 1141 (strong wave energy). The wind is light and cross-shore, so it should be fairly clean. The water is a toasty 80°F, which is a massive 8° warmer than normal for this time of year – seriously unusual. The swell is getting up there, but it’s not massive. For San Mateo, this is probably the pick of the whole outlook. The afternoon sees the wind pick up and get cross-on, making it choppy, so get out early.
After that Monday, it’s a slow fade. The swell drops and the wind stays messy. The morning of Saturday the 1st of August is a bit of a tease – glassy conditions with a tiny 3 ft SW swell, but the energy is weak (246) and the period is short (12 seconds). It’s clean, but flat. For the rest of the fortnight, the surf is poor, with small waves and onshore winds. By the 8th of August, we’re looking at ankle-snappers.
So, if you’re desperate, the Monday morning of the 28th of July is your best bet. It’s not a classic, but it’s the only session that’s worth a look. The rest of the month is a write-off, and the first week of August looks even worse. A long gap of poor conditions, I’m afraid.
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.
