San Mateo Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's cookin' at San Mateo.

It's gonna be a bit of a slow burn over the next week or so, with a lot of cross-shore and onshore wind messing things up. The water is running much warmer than normal for this time of year, which is a bit of a wild card. The first few days are a real write-off, with tiny, poor surf. We're looking at a gap of about a week before anything really starts to get interesting.

The standout session, and the only one I'd really be circling on the calendar, is the morning of Thursday, September 3rd. We've got a glassy 4ft southwest groundswell rolling in with a very long period of 19 seconds. The combined energy is reading 769 (moderate), but that glassy wind is the key – it'll be clean as a whistle. The swell direction from the southwest is a solid match for the optimum, so this point break should be offering up some real lines. It's an advanced, inconsistent spot that can be a bit of a tease, but when it works, it works. Just remember, it's a tricky one for the average punter.

Before that, the morning of Saturday, August 29th, sees the swell bump up to 5ft with 16-second period (1065 combined energy), but there's a stiff cross-shore wind that'll put a bit of a chop on the surface. It's a marginal call at best. The same goes for the morning of Friday, September 4th, with a 5ft to 5ft southwest swell, but again, cross-shore winds will be a factor.

After that Thursday morning window, the winds turn back onshore and the swell drops. The morning of Tuesday, September 8th, has a 2ft swell with a very long 21-second period, but it's going to be breaking straight, and the morning of Wednesday, September 9th, shows a 5ft southwest swell with 17 seconds (1486 combined energy), but it's marginal and the wind is still an issue. It's a long-range promise, so keep an eye on it.

Overall, it's a waiting game. The real prize is that Thursday the 3rd glassy morning. Don't sleep on it.
Rusty.
