The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on the cards for Dee Dees over the next couple of weeks.

Right off the bat, we’re in a bit of a flat spell. The first proper surf window doesn’t open up until Monday the 24th of August, but when it does, it’s a big one – almost too big. We’ve got a solid 8ft SSW groundswell rolling in with a long 13-second period, pushing a massive 2147 combined energy. That’s a lot of water moving around. The wind is light and cross from the NNW, which would keep things clean, but honestly, for a reef break like Dee Dees, that’s expert-only territory. It’s too big for the average punter, and the sheer size and power will make it heavy and challenging. The water temp is sitting at 53°, which is about normal for this time of year, so no surprises there.

The following morning, Tuesday the 25th, the swell drops back to 4ft from the SSW, but the wind shifts to a fresh cross-onshore, and the wave energy drops to 696. The conditions are lumpy and messy, so it’s a skip. That pattern of poor conditions hangs around for a few days, with a mix of onshore winds and lumpy cross-chop.

We start to see a glimmer late in the month. Saturday morning the 29th of August is a standout. The swell drops to a clean 3ft from the S, with a gentle 11-second period. The wind is light and cross-offshore from the N, giving us 261 combined energy and clean, groomed lines. It’s not huge, but for Dee Dees, that’s a fun, user-friendly wave. The catch is that crowds are possible here, so get in early.

The real diamond in the rough, though, is Tuesday morning the 1st of September. This is the pick of the whole forecast. We’ve got a 4ft SSW groundswell with a very long 17-second period. That’s proper groundswell energy, and the combined energy is a solid 802. The wind is light and offshore from the N, giving us glassy, clean conditions. For a reef break, this is perfect. The long period will make the waves powerful, well-shaped, and with longer waits between sets, making it easier to get in position. This is a session to mark on the calendar.

The rest of the first week of September is a mixed bag. The light offshore winds hang around on the 3rd and 4th, but the swell is small and the energy is moderate. Thursday afternoon the 4th has a 5ft SSW swell with 912 energy and clean offshore winds, which is a solid option, but it’s not quite the quality of the 1st. Then we get a late burst on the weekend of the 5th and 6th. Saturday the 5th has a 7ft SW swell, but it’s short-period (6 seconds) and the combined energy is only 308, so it’s a bit of a mushburger for the size. Sunday the 6th, however, is a nice finisher: 6ft S swell, 10 seconds, with light offshore winds and 707 energy. Clean, fun, and a good way to wrap up the run.

So, to sum it up: the first week is a write-off until the big one on the 24th, which is for experts only. The real sweet spots are Saturday the 29th of August for a clean, small wave, and the absolute standout is Tuesday the 1st of September – a long-period groundswell with offshore winds. That’s the one you don’t want to miss.

Stay salty,
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.
