The Lowdown
Alright, Rusty here. Let’s talk about Dee Dees.
The water is sitting at about 56°F, which is a touch warmer than usual for September. Not a big deal, but you’ll feel it’s a bit more comfortable.
The first few days are a snooze. Tuesday morning, September 8th, you’ve got a tiny 3ft swell from the SSW, 10-second period, with a light cross-off breeze. It’s clean, but the energy is weak. Barely worth a paddle. It gets even smaller Tuesday afternoon and Wednesday.
Thursday the 10th is a mess. Strong cross-shore winds, lumpy, and a short-period 4ft swell. No thanks.
Friday the 11th is weird. Only a 2ft wave, but the period is a massive 18 seconds. That’s a very long groundswell, but it’s so small it’ll probably just look fat and slow on the reef. Clean in the morning, but still marginal.
Saturday the 12th is where things get interesting. The morning has a clean 4ft SSW swell, 14-second period, with a light offshore wind. That’s a fun, surfable wave. Then the afternoon goes ballistic: 8ft, 13 seconds, and glassy. That’s a huge amount of energy, but the forecast says it’s too big for this break. For a reef, that’s an expert-only wave.
Sunday the 13th is the same story – 8ft in the morning, glassy, but it’s pushing the limit. If you’re a pro, this is your window.
Monday the 14th is the sweet spot. A clean 5ft SSW swell, 12-second period, and light offshore wind. That’s a solid, well-shaped wave. Tuesday the 15th morning is similar – 4ft, clean, and fun. That’s the best of the run for most surfers.
The second week gets messy. Wednesday the 16th and Thursday the 17th are blown out with strong onshore winds. Friday the 18th and Saturday the 19th see big swells – up to 7ft – but they’re either too big or have poor wind. The final days from September 20th are small and marginal.
The standout: The glassy, 8ft waves on Saturday afternoon, September 12th, and the 8ft on Sunday morning, September 13th, are the biggest, cleanest waves of the whole outlook. But they are only for experts.
The best all-rounder: Monday morning, September 14th, and Tuesday morning, September 15th. 5ft and 4ft, clean, well-shaped, and manageable. That’s the fun, intermediate-friendly session.

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.
