The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Windansea.
To be straight with you, the next couple of weeks are a bit of a mixed bag. We’ve got a long stretch of poor conditions through the middle of the period, but there’s a little window of hope right at the very end. The water temp is sitting about average for this time of year, so nothing too wild there.
We start off with Wednesday and Thursday, September 9th and 10th. The swell is there – a solid 2ft to 3ft from the SW with a very long period of 16 seconds, giving that groundswell energy (379 to 523). But the wind is a problem. It’s light breeze, but it’s onshore or cross-onshore, and the comments call it marginal or poor. The wave energy is moderate, but everything’s a bit messy. Not the kind of day you get excited about.
Then from Friday, September 11th, right through to Tuesday, September 22nd, it’s a real struggle. The wind is either cross, cross-on, or onshore, with a moderate breeze most days, creating a lot of chop. The swell height bounces between 2ft and 4ft, but the period drops off to as low as 8 seconds on the 13th. The combined energy stays in the moderate range (250 to 545), but it doesn’t matter because the conditions are just poor. There’s a solid week and a half where you’d be better off doing something else.
Now, here’s the standout. It’s not a big swell, but it’s the only clean window. On Wednesday, September 23rd in the afternoon, the wind finally swings offshore from the ENE at just 5 km/h. We get a 3ft SW swell with a period of 15 seconds, and the combined energy is moderate (320). The forecast says “expect good surf conditions” – and that’s the first time we’ve seen that in the whole run. The wind is offshore, making it clean. That’s your best bet by a long shot.
After that, Thursday the 24th goes back to onshore wind and poor conditions again.
So, the only real standout in this 16-day window is that Wednesday afternoon, September 23rd, at Windansea. Small, clean, and glassy. Don’t expect much else.
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.
