The Lowdown
Alright folks, Rusty here. I’ve been staring at the charts for the local zone, and I gotta say, it’s going to be a real test of patience. We’re looking at a long, dry spell before we finally see a glimmer of life.
The short version? Don’t bother paddling out for the next week and a half. The surf is tiny, mostly weak, and the conditions are just not there. The combined swell energy is stuck in the low to mid hundreds for the bulk of the first ten days, which tells you how little push there is. We’re looking at a gap of about ten days with no real surf on offer, just marginal bits and pieces.
The first real point of interest doesn’t show up until the end of the month. From Saturday the 29th of August, we finally see a pulse. The swell sizes start to creep up to around 3 ft to 4 ft from the SW, and the combined energy climbs into the strong range. The wind is looking clean, straight offshore from the WNW, which is exactly what a reef like Windansea needs. That said, the guidance is still calling it “marginal,” so don’t expect perfection. But for a spot that’s been dead, this is a welcome change. The water is sitting at a touch warmer than normal for this time of year, about 71°.
The standout session in this whole 16-day window is shaping up to be the afternoon of Saturday the 29th of August. We’ll have a 4 ft SW groundswell with a 16 second period pushing in, combined energy hitting strong, and the wind is pure offshore from the WNW. It’s a reef break, so that long period will wrap in nicely. It’s an advanced wave, and it’s exposed, so it’ll handle the swell. Keep in mind, Windansea can get crowded, and with a pulse like this after a long flat spell, you can bet the local crew will be out. Sunday the 30th of August morning also looks promising with a 3 ft SW swell and light offshore wind, but the energy drops a bit.
After that, things go quiet again. The first few days of September are back to small, cross-on junk and weak energy. The only other flicker is on Thursday the 3rd of September, where we get a 3 ft S swell with moderate energy and a chance of rain, but the wind is offshore. It’s another marginal call, but worth keeping an eye on if the forecast holds.
Basically, save your energy for that last weekend of August. Before that, it’s a whole lot of sitting on the beach watching the horizon.
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.
