The Lowdown
Alright folks, Rusty here. Let’s be straight with you from the get-go. It’s gonna be a long, flat stretch for Windansea. We’ve got a 16-day window, and honestly, the first week and a half is looking pretty grim.
The pattern shows a persistent run of small, weak swell from the SW, but the conditions just aren’t playing ball. For the first several days, the wave comment keeps coming back as "poor surf conditions," so there’s nothing worth paddling out for. You’re looking at a solid gap of about a week from now with no real recommendations.
Even when we see a bit of a pulse around Saturday the 15th, the commentary shifts to "marginal surf forecast or questionable tide conditions," and it's still not enough to get excited about. The combined energy finally climbs above 500 (565 Saturday morning), but with a swell height of only 3 ft and a period of 16 seconds from the SW, it's still pretty underwhelming. The wind stays mostly onshore or cross-onshore, which will keep things messy.
The standout, and it's a reluctant one, doesn’t really show until late in the window. On Wednesday the 26th of August, we start to see some promise. The morning offers 3 ft of SW swell with a 16-second period, but the real kick is the afternoon: the swell bumps up to 3 ft from the SW, the period holds at 16 seconds, and the combined energy hits the highest we’ll see at 687. The wind is a light cross-onshore from the NW at 6 mph, which is light enough to keep things fairly clean. For a reef like Windansea that’s exposed to SW swell and prefers that optimum direction, this is the best on offer. The long 16-second period will give it some real shape, but it’s not huge – fine for most surfers. The water is much warmer than normal at 75°, about 8° above average, which is very unusual for this time of year.
So, be patient. There’s nothing for the first week and a bit. The only real shot at something rideable is the final few days, with that Wednesday the 26th afternoon being your best bet. It’s a long-range call, so don’t stake your life on it, but it’s the only window that lights up. Keep an eye on it.
Rusty.

Information about the Windansea Surf forecast
The above surf forecast table for Windansea provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Windansea can be found by selecting the local surf guide option on the grey menu. Our Windansea 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 (Windansea) 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 Windansea 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.
Windansea is 10 km (6 miles) from San Diego. If you plan a vacation in San Diego County, look for hotels and other accommodation in San Diego. San Diego has rooms for a wide range of budgets as well as car hire and transport links.
