The Lowdown
Alright, folks. Rusty here. Let’s break down what’s happening at Dee Dees over the next couple of weeks.
The first few days are a total washout. Thursday and Friday are hammered by strong cross-shore winds and messy, lumpy conditions. Not a single wave worth paddling for.
Then on Saturday, August 1st, a massive pulse hits – waves up to 16 ft from the SSW. The wind is cross-onshore, and the conditions are poor. That’s a beast for experts only, and the quality is just not there. The combined energy is huge (5121 in the morning, 5995 in the afternoon), but it’s a rough, choppy mess.
Things flip on Sunday, August 2nd. The morning is still a bit marginal with a 6 ft S swell and a gentle cross-onshore breeze. But the afternoon is the real gem. The wind goes glassy, the swell drops to 5 ft from the SSE, and the period is a solid 11 seconds. That’s clean, long-period groundswell – perfect for this reef. The combined energy is 720. This is your best window in the first week.
The rest of the first week is a mixed bag. Monday and Tuesday morning are clean but small or too big. Tuesday morning, August 4th, has a massive 16 ft SSW swell with a 13-second period and combined energy of 8486. Way too big, even for experts. The wind is light cross-onshore, but it’s a no-go.
The second week offers a couple of real highlights. Thursday, August 6th is a winner. Offshore winds from the NE, a clean 4 ft SSE swell with an 11-second period. Glassy, clean, combined energy of 842. Perfect for the intermediates.
Friday, August 7th is clean too, with offshore winds and a 8 ft to 10 ft S swell. At 8 ft, it’s expert territory, and the afternoon’s 8-second period gives a shorter, steeper wave. Good for the experienced crew.
Saturday, August 8th stays clean, with a 8 ft to 8 ft SSE swell and a 9-second period. Combined energy of 1222. A solid option, but the crowds are “sometimes” – so expect some company.
After that, it falls apart. By August 9th, the wind picks up and conditions go poor. The 14th of August is a real letdown – tiny 1 ft swell with a 12-second period, combined energy of only 72. Weak and ordinary.
So, the two to circle are Sunday afternoon, August 2nd – glassy, clean, 5 ft SSE – and Thursday morning, August 6th – offshore, clean, 4 ft SSE. Those are your sessions.
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.
