The Lowdown
Alright folks, Rusty here. Let's chew through what the next couple of weeks look like for us.
First up, the water's running a touch warmer than usual at about 72°, which is a nice little bonus for the session.
Honestly, for the first week and a half, it's a bit of a grind. We've got a long stretch of poor conditions and marginal calls starting Monday the 7th through to about the middle of the month. The swell is there – around 6ft from the SSW on Monday with moderate energy (957), but the wind is a messy cross-on, ruining any chance of clean lines. It's just choppy and frustrating. We see the swell drop off quickly after that, and the wind stays stubbornly cross or cross-on. There's a bit of a long-period (16 seconds) groundswell trying to get going around Wednesday the 9th, but it's small (2ft) and the energy is weak (378). This pattern of onshore junk and small, poorly aligned swell hangs around for days. The combined energy values during this period are mostly in the 300 to 500 range, which is weak to moderate at best. You're looking at a solid 8 to 9 day stretch where the best call is "questionable tide conditions."
Now, here’s where it gets interesting. After that long dry spell, there's a real glimmer of hope. The best on offer across the whole forecast is shaping up for the weekend of the 18th and 19th. On Friday the 18th afternoon, we finally see a switch. The wind goes glassy off the WNW, and the swell is a clean 2ft from the SW with a very long 19-second period (517 energy). That's a proper groundswell. For a reef break like Windansea, that long-period SW energy is exactly what you want. It'll be small but perfectly shaped.
But the standout, the one to circle on your calendar, is Saturday the 19th afternoon. It's glassy calm, zero wind, with a 3ft SW groundswell rolling in at 18 seconds (596 energy). That's about as clean as it gets. The swell direction matches up perfectly with what this break loves, and with no wind, it’s going to be smooth, peeling lines. This is the pick of the entire 16-day window. The morning of the 19th is marginal, but the afternoon is the real deal. There’s a chance of crowds here as it’s often busy, but for conditions like that, it’ll be worth jostling for position. The following week looks to stay marginal again with small SW pulses and light winds, but nothing that compares to that Saturday arvo.
So, to sum it up: don't waste your time for the first week and a half. Wait it out. The real window is the 19th afternoon. Glassy, clean, and the right swell direction. That's the one.
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.
