The Lowdown

Right, folks, Rusty here. Let’s get into it. We’ve got a 16-day window on the cards, and for the first few days, it’s a write-off. The wind is howling and the swell is way too raw, so we’re looking at a gap of a few days before anything even gets close to surfable.

The first real chance to wet a line won’t be until the morning of Thursday, August 6th. Even then, it’s slim pickings. Expect weak, 5ft to 6ft south swell with a period of 10 to 11 seconds, and the combined energy is only moderate (526 to 923). The wind is light offshore though, which is a big positive for clean conditions. It’s marginal, but the best bet on offer for a proper session looks like Friday morning, August 7th. The swell drops a touch to 4ft from the south, but the period stretches way out to 16 seconds—that’s proper groundswell. The offshore wind will have the waves clean, and while the energy is still moderate (1138), that long period means the waves will have some proper shape. Dee Dees is a reef, so that long-period swell will wrap in nicely.

Now, if you’ve got the skills and a bit of bravery, the standout of the whole outlook is Wednesday, August 19th. The swell is pumping hard from the south-west, hitting 12ft in the morning and 10ft in the afternoon. The period is a reasonable 10 seconds, and the combined energy is strong (2347 to 2047). The wind is glassy—dead calm in the afternoon. That’s as good as it gets for a big, clean, proper wave. But I’ll be straight with you: at that size, 10ft to 12ft, this is for experts only. The reef will be working, but the crowd factor is something to watch—Dee Dees can get busy. If you’re not a confident surfer, steer well clear of that day.

Other than that, the rest of the window is mostly blown out, choppy, or just too small. Sunday morning, August 9th, has a tiny 3ft south swell with glassy conditions, but it’s weak. The morning of Monday, August 10th, has a 3ft to 3ft south swell with clean cross-offshore wind, but it’s very ordinary. The second week is a bit of a downer: a lot of small, powerless swell and poor wind, with a few days of nothing at all. The 12th and 13th are tiny, with periods as low as 8 seconds, and the combined energy is weak (25 to 65). The 14th to the 17th are mostly messy or onshore, with a few marginal windows. The 18th has a moderate 6ft to 7ft south-west swell, but the wind is cross-onshore, making it lumpy.

So, for the overall picture: the first week is a write-off until Thursday, August 6th, with the best pick being Friday morning, August 7th for clean, long-period groundswell. The true standout, if you’re up for it, is Wednesday, August 19th for the big, glassy, expert-only waves. Surf’s not looking great for the rest of the second week unless the forecasts change.

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.
