Table - best surf conditions forecast for San Mateo over the next 16 days.
Alright folks, Rusty here. Let's have a look at the 16-day outlook for San Mateo. Honestly, it's a bit of a tough stretch. We're looking at a long run of marginal to poor conditions, with a lot of cross-shore and cross-onshore wind messing things up. The water is a whopping 4° warmer than usual right now, which is very unusual for this time of year.
The first real chance of anything half-decent doesn't show up until Friday morning, the 10th of July. The swell is a weak 3ft from the SW with a long 16-second period, which is good for a point break like this, but the energy is moderate at best (503). The wind is light and cross-shore, so it'll be clean, but the forecast says it's only marginal. Not exactly firing.
Saturday morning the 11th is similar, with a 4ft SW swell and a 14-second period (536 energy). The wind is a gentle cross-shore, so it'll be rideable, but again, it's only a marginal call. The afternoon gets chopped out.
We then hit a real flat spell. From Sunday the 12th right through to the 20th of July, it's a lot of junk. Swell drops right off, and the wind is never good. The 21st of July, Tuesday morning, shows a bit more size – 5ft from the SW with a 14-second period. The energy bumps up to 884, which is getting into moderate territory, and the wind is a gentle cross-shore. It's still marked as marginal, but it's the best-looking window in the whole outlook. The afternoon gets messy with a stronger cross-shore wind.
After that, it fades out again. The 23rd and 24th see a shift in direction to WNW and NW, but the size is tiny and the wind is hopeless.
So, the standout here is that Tuesday morning, 21st of July. It's the only time the swell and wind line up even close to decent. For a break that's inconsistent and exposed to the NW, this is your best bet. Keep an eye on it, but don't hold your breath for the rest of the fortnight.
Rusty.

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.

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.
