San Mateo Surf Forecast and Surf Report

Alright, let’s get into it. This is Rusty, and I’ve been looking over the San Mateo forecast for the next couple of weeks. Gotta be straight with you – it’s a bit of a mixed bag, but there are a couple of windows that will get you out there.

First up, we’re looking at a point break that’s generally inconsistent, so when it’s on, it’s a treat. The water temp is sitting about average for this time of year, so nothing wild there.

The first few days are a washout. Thursday the 17th is a no-go with poor surf and a messy cross-chop. Friday the 18th morning shows a little life with a 3ft SW swell at 12 seconds and clean conditions thanks to a light cross-offshore breeze. The combined energy is moderate (292), so it’s not a bomb, but it’s the best early call. Saturday the 19th morning drops right off to 1ft, so don’t bother.

We hit a big gap after that. From Sunday the 20th through to Tuesday the 22nd, it’s mostly poor conditions with onshore winds and chop. Nothing worth paddling out for. There’s a marginal call on Wednesday the 23rd morning with a 3ft SW swell at 7 seconds (short period, weak energy at 236), but the wind is light and cross so it’s not completely hopeless, just not great.

Now, here’s where it gets interesting. Thursday the 24th morning has a 2ft SW swell, but the period is a very long 21 seconds – that’s groundswell energy and it’s packing strong energy (737). The wind is light and cross, so it’s clean, but that long period can make a point break like this really line up. It’s a marginal call, but worth a look for the patient surfer.

The standout is Saturday the 25th morning. Glassy conditions, 3ft SW swell with a 19-second period, and strong energy (821). This is the best on offer in the whole run. Clean, long-period groundswell hitting the point with no wind – that’s a proper session if you can get it. Only downside is the crowds are possible, so get there early.

Sunday the 26th morning bumps up to 4ft SW at 17 seconds with very strong energy (1156), but the wind is cross and it’s marginal. Afternoon gets choppy. Monday the 27th and Tuesday the 28th mornings both have 4ft SW swell with 15-17 second periods, clean conditions, and very strong energy (1139-1258). These are solid, consistent days for the advanced crew, and the swell is over 5ft so it’s pushing into more serious territory for beginners.

The rest of the run fades out. Wednesday the 29th morning has a 3ft SW swell at 15 seconds with moderate energy (501), but it’s cross and marginal. After that, it’s a lot of poor conditions and onshore winds until the end of the period on August 1st.

Overall, if you’re picking one, make it Saturday the 25th morning for the glass and the long-period groundswell. The 27th and 28th are also strong but will be a bit more challenging with the size. The inconsistency of this spot means you gotta be ready to move when it’s good.
