The Lowdown
Alright folks, Rusty here with a look at what's coming up for Windansea. It’s a bit of a mixed bag, so let's get into it.
Right off the bat, we’re looking at a fairly drawn-out stretch of small, marginal surf. The early part of the forecast is pretty quiet, and we’re not seeing anything worth getting excited about for the first several days. We've got a gap of poor to marginal conditions that runs basically from now right through the first week, with only light, cross-onshore winds and small swell making it tricky.
The water is sitting at 72°, which is a touch warmer than normal for this time of year—a nice little bonus if you’re paddling out in a thin suit.
Now, the standout window, and the only real bright spot here, is that weekend of the 18th and 19th of September. We start seeing the combined swell energy ramping up into the moderate range, hitting around 535 to 568 (moderate wave energy) early on the 18th. The wind looks like it will be light and offshore from the WNW, which is a major positive for Windansea. This means clean, lined-up waves. We’re looking at a SSW swell of 2ft to 3ft, but with a very long period of 18-19 seconds. That's proper groundswell, and it'll be a slow, powerful pulse. For a reef break like Windansea, that long period is a beautiful thing—it’ll wrap in and offer some really nice, shapey walls, though the sets will be a bit spaced out. This isn't for beginners; the wave itself can be a bit of a handful.
Crowds are a reality here, described as "often" busy, so don't expect to have it to yourself. But for a reef break with the right direction and clean wind, it’s worth the company. The 19th looks similar, with a slight shift to a light cross-shore, still solid energy and clean conditions.
Beyond that, into the later part of the month, we drop back into the smaller, wind-affected stuff where you'll be fighting the breeze for anything rideable. The call is to make the most of that weekend window.
This is Rusty, signing off.

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.
