The Lowdown
Alright, Rusty here, let’s have a look at what’s cookin’ at Dee Dees.
The next 16 days start off with a real flat spell. The first couple of days have surf, but it’s not worth paddling out for. Sunday the 9th is a write-off with a messy 5ft cross-shore wind and weak, short-period swell. Monday the 10th is tiny and clean but only 2ft at best – not enough to get excited about. You’re basically waiting until Tuesday the 11th for the first real pulse.
Tuesday morning (11th) sees a bump in size to 6ft from the south, but it’s cross-shore with light wind ripples – just marginal. The afternoon cleans up a bit with a cross-off breeze and 5ft SSE swell, but it’s still pretty ordinary. Wednesday and Thursday are flat or tiny, with Thursday afternoon (13th) showing a glimmer of hope: glassy conditions and a 4ft easterly swell. That’s clean but small. Then Friday (14th) is tiny, with only 0.7ft waves – forget it.
Now, hold onto your board, because Saturday the 15th morning is a beast. We’ve got a solid 15ft SSW swell, but it’s too big for Dee Dees – the combined energy is massive (2718) – and it’s a reef break, so that’s expert-only territory if anyone’s crazy enough. The wind is cross-shore and messy. The afternoon gets worse with strong cross-onshore winds. Sunday the 16th and Monday the 17th are huge again (8ft to 21ft) but with terrible onshore winds – this is more of a kite-surf show than a paddle session.
The real standout comes later in the forecast. Thursday the 20th morning is the gem of the outlook: a clean, cross-off breeze, 5ft south swell with a nice long period of 11 seconds, and glassy conditions in the afternoon with 4ft. The swell direction (S) matches the optimum for Dee Dees, and with light winds, it’ll be clean and fun. The water temp is about 54°F with a small anomaly of +0.5°F – pretty average for this time of year. Crowds can show up here sometimes, so you might have some company on the reef.
Friday the 21st morning is also decent – glassy, 4ft south swell, long period – a close second. Saturday the 22nd stays clean with offshore winds and 3ft south swell. After that, it fades into tiny, ordinary surf through the end of the month.
So, the best bet in this 16-day window is definitely Thursday 20th August and Friday 21st August mornings. Clean, chest-high waves with a bit of energy. Everything else is either flat, too big and blown out, or just not worth the effort.
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.
