The Lowdown

Alright, Rusty here. Let's break down what we've got on the horizon for Dee Dees. This spot is a reef break, pretty consistent, and it likes swell from the south.

Right off the bat, we're looking at a bit of a slow start. The first few days are pretty ordinary, with the 16th and 17th offering nothing but messy, cross-shore junk. The water temps are sitting at 56°, which is a touch warmer than normal for this time of year.

Thursday the 18th is a glimmer of hope. Friday morning we get a clean 3ft swell from the south with light offshore winds. It's only a 6-second period, so it'll be a bit weak and crumbly, and the combined energy is only moderate (190), but it's the first sign of life. The afternoon stays clean with a 1ft SSW groundswell, but it's tiny.

Now, Saturday the 19th of September is where it starts to get interesting. Saturday morning is a standout. We've got a clean 4ft swell from the SSW with a very long 15-second period and light offshore winds. The combined energy is strong at 792, so there's proper power behind it. That's a proper long-period groundswell, which on a reef like Dee Dees should shape up into some nice lines. It will be well overhead, but the long period means longer lulls between sets, which helps with the paddle out. The afternoon gets ruined by a cross-shore breeze, so make the most of the morning.

Sunday the 20th is a write-off. We get a massive 12ft SSW swell, but it's accompanied by a fresh, onshore wind. That's just a washing machine. The combined energy is strong (1476) but the quality is zero.

Monday the 21st is for experts only. The morning has a huge 12ft SSW swell (2667 combined energy) and the wind is light, but the forecast flat-out says it's too big for this break. The afternoon drops to a still-very-serious 7ft with clean, offshore wind, but again, it's too big for most.

Things settle down through the middle of the week, but the quality is poor with a lot of onshore wind. There's a brief window on Friday the 25th of September with a clean 4ft S swell and light offshore wind. It's a solid chest-to-head-high size, with moderate energy (359) and a short period of 9 seconds, so it'll be fun but not firing.

Then we get another promising window around Monday the 28th of September. The morning shows a clean 8ft SSW swell with a long 13-second period, light offshore wind, and a very strong combined energy of 2250. Again, for Dee Dees, 8ft is big, likely expert territory. The afternoon is slightly smaller at 8ft but shifts to a cross-shore breeze.

Finally, Tuesday the 29th of September offers a real highlight in the afternoon. We get a clean 6ft S swell with a 12-second period. The wind is light offshore, and the combined energy is strong at 850. This is a proper window for intermediate to advanced surfers. Good, powerful lines with clean conditions.

For the absolute best on offer, I'd lock in Saturday morning the 19th of September for a session of that long-period, clean SSW swell. It'll be nicely overhead and the reef should handle the direction well. The second call is Tuesday afternoon the 29th of September for a similar, slightly smaller, very clean window. If you're an expert, the Monday the 28th of September is worth looking at, but it is big.

Keep in mind, after that, we run into a gap with nothing but small, weak, or onshore junk through to the end of the outlook on October 1st. So make the most of those windows.

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.

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.
