The Lowdown
Alright, grab your coffee, let's have a look at the next couple of weeks.
To be straight up with you, the next ten days or so are looking pretty average for us here. We've got a consistent stream of small, long-period SW groundswell rolling in, but the wind is just not playing ball. For most of this stretch, we're looking at cross-onshore or onshore breezes, which are going to keep things choppy and messy. The water is sitting at a very warm 74°F, which is about 6°F warmer than usual for this time of year – that's a real standout. You'll be in boardies for sure.
For the first week, from Saturday the 15th through to about Friday the 21st, it's honestly a write-off. The wave energy is low, between 200 and 600, and with those winds, the conditions are just poor. You'd be fighting a losing battle out there. Even the light winds mid-week don't save it because the swell is tiny – around 2ft to 3ft. It’s not worth the paddle.
Things start to look a little more interesting from Monday the 24th. On Monday afternoon, we get a brief window of glassy conditions with a 2ft S groundswell, period of 20 seconds. That's a very long-period groundswell, so at a reef like Windansea it could offer some nice, clean lines, but the energy is moderate at 469. It's just a tease, though.
The real standout, the one you want to circle on your calendar, is the 25th and 26th of August. We’ve got a proper pulse of S and SSW swell coming in. On Tuesday the 25th, the swell jumps to 5ft-6ft with a period of 15-16 seconds and the combined energy rockets up to 1546 – that's strong. The wind on Tuesday morning is a light cross-onshore, so it might have a little texture, but it's still the best surf we've seen. This is pushing into the more powerful range, so it'll be a step up from the dribble we've been having. Wednesday the 26th holds similar size, around 6ft-6ft from the SSW, with a period of 13-14 seconds and energy still over 1000. The wind is a gentle cross-onshore, so it won't be perfect, but there will be plenty of waves. This is definitely the pick of the fortnight for the more experienced surfers.
After that peak, it fades through the end of the month. Thursday the 27th and Friday the 28th still have some decent size, around 5ft-6ft, but the wind is mostly onshore or cross-onshore, so expect it to get lumpy. The wave energy drops back to the 600-1200 range. By the weekend of the 29th, we're back to small, messy 3ft-4ft surf with onshore winds.
So, in short, save your energy for that Tuesday the 25th and Wednesday the 26th window. It’s not all-time, but it’s the only real show in town.

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.
