The Lowdown

Alright, Rusty here. Let’s have a look at what San Mateo has in store for us over the next couple of weeks.

Straight up, it’s a patchy outlook. The first couple of days, Thursday the 23rd and Friday the 24th of July, are a write-off. The swell is tiny – we’re talking ankle-snappers at best – and the wind is messing things up with a cross-chop. Not worth paddling out for.

The first real glimmer of hope is Saturday morning, July 25th. The wind drops right out, going glassy, and that’s a huge deal for a point break like this. We’ve got a 3.3ft swell from the SW with a period of 19 seconds. That’s a long-period groundswell, which means proper shape and energy, though on a point it should line up beautifully. The combined swell energy is moderate at 775 – enough to get you moving. It’s an advanced wave, inconsistent, so you’ll be waiting for sets. But if you’re on it, those waves will be clean and lined up. Crowds are *sometimes* around, so you might have company.

Sunday morning, July 26th is another standout. Again, glassy conditions with a light wind from the SE – doesn’t get much better for clean faces. The swell picks up just a touch to 3.6ft from the SW, period dropping to 17 seconds – still a long groundswell, still good energy (795). This is your best bet for a smooth, peeling wave.

After that, the week gets messier. Monday the 27th through Wednesday the 29th sees the swell building to 4.9ft, but the wind swings onshore and chops everything up. The energy is high (over 1000 on Monday), but it’s not going to be pretty. Too big and blown out for the average punter, and for a point break, that cross-onshore wind will kill the line. Thursday the 30th and Friday the 31st sees the swell dropping back down, but the wind is still a problem – cross-shore chop. Not worth it.

Into the first week of August, from the 1st to the 7th, it’s a pretty flat, blown-out string of days. The swell is under 3.3ft for most of it, and when it does bump up slightly, the wind is never favourable. The combined energy drops right off into the double digits and low hundreds. It’s a long, quiet stretch with no clear windows. The water temperature is about average for the time of year, so nothing unusual to report on that front.

Overall, the only real windows to get excited about are that Saturday and Sunday – the 25th and 26th of July – when the glassy mornings give us clean, long-period groundswell. The rest is a gamble at best, and mostly a dud.

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.
