The Lowdown
Alright, Rusty here. Let’s break it down for the imperial crew.
Right off the bat, it’s a slow start. From Tuesday 28 July afternoon through Tuesday 4 August morning, we’re dealing with small, choppy junk. Swell heights run from around 0.5ft up to 4ft, but the wind is mostly cross or cross-on, and the wave energy is on the low side (from 1156 down to 92). Nothing you’d paddle for unless you’ve got nothing else.
The water is cooking at 81°, a solid 9° warmer than normal for this time of year.
There’s a glimmer of hope on Wednesday 6 August morning when the wind goes glassy, but the swell is only 2ft and weak. Then on Friday 7 August morning, we see a jump to 3ft from the SW with a period of 16 seconds (long period groundswell – great for a point break like San Mateo). Not completely clean, but it’s a step up.
The clear standout is Saturday 8 August morning at San Mateo. You’re looking at a clean 4ft swell out of the southwest, with a gentle cross-off breeze. That means glassy, clean lines on the point. The wave energy is solid (539), the period is 14 seconds (proper power), and exposure is to the NW, which fits well. Crowds are listed as sometimes, so you might see a few others, but it’s worth the early alarm.
Sunday 9 August morning also looks decent with a 3ft SW swell and glassy conditions – a nice smaller-wave session. After that, the afternoons get choppy and ordinary again through 12 August.
Bottom line: hold out for Saturday 8 August. That’s the one.
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.
