The Lowdown
Alright, Rusty here again. Let’s break down the next couple of weeks at the San Jose Rivermouth in feet and Fahrenheit.
The first week is pretty flat. Swells are tiny, barely hitting 2 to 3 feet most days. The water is a warm 85°, which is about 4° above the usual for this time of year—feels like a hot tub. The wind is a problem early on, with a lot of cross-on or onshore breezes and afternoon thunderstorms possible. The combined swell energy is weak, mostly under 300 (moderate energy) but often less. Monday morning, the 3rd of August, has glassy conditions with a 2-foot SSW swell at 13 seconds, but it’s very ordinary.
The real standout is Friday the 7th of August afternoon. That’s when we get a clean 3-foot swell from the SSW, with a 17-second period—that’s proper long-period groundswell. The wind is cross-offshore from the WSW at 9 mph, keeping the surface clean. The combined energy is 574 (moderate), and the conditions look good. The river mouth will handle that long period, but expect longer waits between sets.
After that, there are a few other options, but nothing beats Friday. Saturday the 8th of August morning has a bit more size at 4 feet, but the wind is onshore, so it’s messier. The 11th of August Tuesday morning has a 3-foot SSW swell with an 18-second period and energy of 760 (moderate), but the wind is cross-on. The 13th of August Thursday morning is similar, with lighter wind.
The last week gets messy. The 14th of August Friday has a 5-foot SW swell, but with strong onshore winds and energy over 1400 (strong), it’s more of a kite-surfing day than a paddle day. The 16th of August Sunday afternoon looks clean again, but it’s a long way off.
Bottom line: Friday the 7th of August afternoon is your best shot. The rest is small or blown out.
Rusty.

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 Jose Rivermouth 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.
