The Lowdown
Alright, Rusty here. Let’s chew the fat on what Windansea is serving up.
The next two weeks are a bit of a rollercoaster, but there’s a couple of sweet windows. The water is a toasty 73°, which is a good chunk warmer than usual for early September – about 5° above the norm. That’s a real bonus.
Friday the 4th morning is where I’d be pointing the car. We’ve got a clean 3ft southwest swell with a very long 17-second period. The combined energy is moderate at 624, and the wind is light offshore from the west. That’s perfect, clean reef conditions. It’s not a monster, but the quality from that long period swell will be there. Expect nice shape.
Saturday the 5th is the other real highlight. The swell builds to 4ft from the south in the afternoon, with a 13-second period and still light offshore winds. The energy jumps to a strong 1082. This is probably the biggest, most powerful surf of the whole outlook. It’s solid but not insane.
Now, the caveat hits Sunday the 6th. The swell is up around 6-6ft from the south-southwest, but the wind swings to the northwest at 12 mph, cross-onshore. The energy is strong, over 1100, but it gets choppy. The quality drops.
From Monday the 7th onward, we’re stuck in a pattern. The swell stays around 5-6ft, but the wind is consistently from the northwest, either cross-onshore or onshore, making things lumpy. The energy stays high but the wave comment calls it marginal. By Wednesday the 9th, the size drops to 5ft and the period shortens to 11 seconds. The wind goes light offshore again, but the energy has faded to 614.
Then the wheels fall off. Thursday the 10th the swell drops to 3ft, and by the 11th it’s 3ft with a choppy northwest wind at 12 mph. The wave comment says poor. From the 12th through the 17th, we’re in a flat spell. Heights barely hit 2ft, and the energy drops well below 400. This is a proper lull.
There’s a tiny blip on Monday the 16th with a 4ft west swell, but it has a short 8-second period, so it’ll be weak and crumbly. The week of the 18th sees a little pulse back to 3ft with long 18-20 second periods and light offshore or light cross-onshore winds. It’s still marginal.
So my take: hit Friday the 4th morning or Saturday the 5th afternoon. That’s the cleanest, most energetic window we’ve got. After that, you’ve got a long, flat stretch until maybe the 18th, but that’s a long way out and not certain.
If the wind stays up, some of those choppier days might be more fun on a kite.

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.
