The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Windansea over the next couple of weeks.
Right off the bat, I gotta be straight with you – the next week or so is looking pretty grim. The water is a toasty 72.1°F which is a full 5.4°F warmer than usual for this time of year, which is very unusual. It’s like a bath out there, but the surf is flat and the wind is a mess. The first couple of days are a write-off with tiny, weak 1.6ft SW swells and cross-shore breezes kicking up a chop. You’d be better off on a paddleboard than a surfboard.
We do see a bit of a pulse building through the weekend and into the start of the week, but it's all marginal. Swells are coming from the SW, which is the optimum direction for the reef, but the energy is all over the place. The morning of Sunday the 19th sees the combined energy jump to 701, but with a cross-on wind and only 2.6ft of swell, it’s just not going to be a classic. There's a slight improvement on Monday the 20th with a 3.9ft SSW swell and offshore winds in the morning, but the period is only 12 seconds and the energy is moderate at 667. It’s a 'maybe' session at best.
If you can wait, the real standout window starts to open up around Friday the 24th of July. The morning shows a 2.3ft SW swell, but here’s the kicker – the period jumps to a very long 24 seconds. That’s proper groundswell energy. The combined energy is a solid 1074, and the wind is light. This is a classic setup for Windansea. That very long period will make the waves peel beautifully down the reef, but it's worth noting that kind of period can make the sets a bit lully and the waves a bit straight at certain beach breaks. For a reef like Windansea, it's a dream. This is the best on offer, and it's promising.
The following weekend (Saturday the 25th and Sunday the 26th) keeps that energy up with readings over 1000 and light offshore winds, but the swell direction wobbles a bit. It’s still good, but the 24th is the one to circle.
The end of the run, around the 31st of July, sees a bigger pulse of 5.9ft SSW swell in the morning. That’s getting into the "too big for beginners" territory, but for the advanced crew out there, with a light offshore wind and a period of 14 seconds, it could be a solid, punchy day. The energy is strong at 1339. It’s a long way out, so keep an eye on it, but it's got potential.
So, to sum it up: the first week is a slog. The best bet is the morning of Friday the 24th of July for that classic, long-period SW groundswell. The end of the month might also throw up a bigger, more powerful session for the experts.

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.
