The Lowdown
Alright folks, Rusty here. Let's take a proper look at what Dee Dees has in store for us over the next couple of weeks. The overall picture is a bit of a patience game. We're starting out with a real mixed bag, a few days where you might want to hang onto the couch, but there's a big, powerful, and slightly tricky swell on the horizon that could make it all worthwhile for the right crew. The water temp is sitting at 54°F, which is pretty much spot-on for this time of year, nothing wild there.
Right off the bat, Saturday the 25th is a write-off. We've got an 8ft SSW swell, but it's coming in with a short 7-second period and a fresh 22 mph cross-onshore wind. The combined energy is moderate (663), but the quality is poor. It's lumpy, choppy, and not worth suiting up for.
Sunday the 26th and Monday the 27th are marginal at best. Swell drops right down, the winds stay cross or cross-onshore, and the energy levels are low. For Monday afternoon, you see a 3ft, 11-second period SSW swell with a light cross-onshore, which has moderate energy (433), but the comments say it's poor surf. Leave it.
The real interest starts to build around Tuesday the 28th. We get a small, glassy morning with a 3ft swell from the SE at a very long 12 seconds. The combined energy is weak (308), but it's clean. Tuesday afternoon is even better—totally glassy, same 3ft SE swell stretching out to a 13-second period. The wave comment is "expect good surf conditions." This is the first true standout. It will be clean, the wind is dead calm, and that long period will make for some nicely shaped lines over the reef at Dee Dees. It's just small, so it's for everyone, but it's a beautiful window.
We then hit a long, flat, and windy patch. Wednesday the 29th through to Monday the 3rd of August is a real downer. Winds get up, the swell disappears, and most days are a mix of poor surf or very ordinary conditions. That's a solid 4-5 day gap where you're better off doing something else. There's a tiny bump in energy on the 1st of August with a glassy 1ft SE, 16-second period swell, but it's barely a ripple.
Now, hold onto your boards, because things get very interesting around the 5th of August. On the morning of Wednesday the 5th, the model is calling for a monster 12ft SSW swell with a 9-second period. The combined energy is a massive 2104—that's strong to very strong energy. The wind is a light 6 mph cross-offshore from the NNE, and the notes say conditions are clean. However, the key comment is "the swell is predicted to be too big for this break." This is 12ft. At Dee Dees reef, that's expert territory, maybe too big even for some of the local chargers. This pattern continues through the 7th, with swells over 8ft and periods stretching out to 13 seconds, all with clean offshores. The energy numbers are through the roof: 3171 on Friday the 7th. This is for absolute experts only. If you're not in that boat, stay on the sand and watch.
Finally, the swell eases into a more manageable range. Saturday the 8th still has a 7ft S swell at 11 seconds in the morning with a clean cross-offshore, and it's still a bit big for most. But the true last standout is the afternoon of Saturday the 8th. The swell drops perfectly to a 7ft S swell at a juicy 12 seconds, with glassy conditions from NNW winds. The energy is strong (1113), and the note says "excellent surf conditions for experienced surfers." This is the one. It's still a solid overhead wave with tons of energy and a long period, meaning it'll be powerful and lined up on the reef. It's not for beginners, but for anyone with the skills and the nerve, this Saturday afternoon window in the second week looks like it could be the session of the period. Crowds are listed as "sometimes" at Dee Dees, so on a quality day like this, you can expect a few other keen locals in the water.
Overall, it's a rough start, a quiet middle, but a big, powerful finish that demands respect. Keep an eye on that second weekend.
Rusty.

Information about the Dee Dees Surf forecast
The above surf forecast table for Dee Dees provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dee Dees can be found by selecting the local surf guide option on the grey menu. Our Dee Dees 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 (Dee Dees) 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 Dee Dees 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.
