The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next couple of weeks are a bit of a mixed bag for Windansea. It’s a reef break that’s exposed to SW swell, and it’s fairly consistent, but we’re going to see a lot of marginal days before things finally click into gear. The water temp is sitting around 70°, which is about normal for this time of year.
From Thursday the 20th of August through to Wednesday the 2nd of September, it’s pretty grim. Swell is tiny, mostly under 3 ft, with periods all over the shop. The energy is weak to moderate – values are mostly in the 200 to 400 range (combined energy), which isn’t enough to get excited about. Winds are mostly light but cross-onshore or onshore, so the surface is going to be messy. There’s a few mornings with light breezes, but the wave comment keeps saying “poor surf conditions” or “marginal” – there’s just nothing to write home about. You’ll see a small bump on the 26th of August where the swell picks up to 4 ft from the SSW, with a 13-second period, and energy hits 870, but it’s still cross-shore wind and the wave comment says “marginal.” It’s a pass for me.
Then we hit a dry patch from the 31st of August through the 1st and 2nd of September – still small, still crummy, with energy dropping back into the 300s. On the 1st of September, the swell direction swings to WNW with a short 8-second period, and the wind is a moderate cross-shore from the S at 16 mph. That’s not surfable, that’s kite-surfing weather if anything.
But hold on, because Thursday the 4th of September is the standout. Morning session is looking special. We’ve got a 4 ft SSW swell with a 17-second period – that’s proper groundswell, long-period energy, which tends to shape up well at reefs like Windansea. The wind is glassy, from the WSW at just 3 mph, which means the surface will be clean as a whistle. The combined energy is 984 – nearly strong, and the wave comment says “expect very good surf conditions.” That’s your window. The afternoon firms up with a similar 4 ft swell and energy over 1000, but the wind swings to a cross-shore from the S at 9 mph, so the morning is the pick.
For the long haul, the 4th of September morning is the best on offer – glassy, long-period SSW groundswell, and a reef that loves that direction. Get in the water.

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.
