Table - best surf conditions forecast for San Mateo over the next 16 days.
Alright, Rusty here. Let’s break it down.
First few days are a bit flat. Sunday the 12th and Monday the 13th of July have some small southwest swell coming in, but the wind is all over the place – cross and cross-onshore – making for choppy, unappealing conditions. Nothing to get excited about.
Now, Wednesday morning the 15th is where it’s at. San Mateo, an inconsistent point break, will get a nice 1.0ft (0.9m) southwest swell with a long period of 16 seconds – that’s real groundswell, carrying good power (429). For a point break, that long period will set up some decent lines. The wind will be light and cross-offshore, keeping the surface clean. This is for advanced surfers only, and crowds are possible.
From the 16th through to the 25th, it’s a dry spell. Wind is mostly onshore or the swell drops off to almost nothing (0.3m to 1.0ft) with poor periods. Not worth your time.
Then we get a second chance on Sunday the 26th of July. Glassy conditions, no wind at all. The swell is a small 0.6m (2ft) from the southwest, but with a long period of 17 seconds, it’ll have more shape than the size suggests. Energy is moderate (232). For an inconsistent spot like San Mateo, this is a rare glassy treat. Again, for advanced surfers.
The last day to note is Monday the 27th, with the strongest energy we’ve seen (478), a 0.9m (3ft) southwest 14-second swell, but with a light cross-breeze. Worth a look, but the Sunday glass-off is the winner.
Water’s way warmer than normal for this time of year – about 81°F (27°C), so no wetsuit needed.
Rusty, out.

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.
