The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, it’s a pretty grim run for Seaford Reef. The whole 16-day window is basically a write-off. There’s no surf of any real consequence to get excited about, and every single entry in the forecast is marked as “poor surf conditions.” It’s one of those frustrating stretches where you’d be better off leaving the board in the car and doing something else.
The pattern starts on Monday the 10th of August with a weak 3 ft swell out of the WSW, but the wind is onshore and the combined energy is only a feeble 61 (low energy). That’s not going to do anything. Tuesday the 11th is even worse – a messy cross-shore wind and a choppy mess. The water temperature is sitting at 57°, which is about 1° cooler than average for this time of year, so nothing unusual there, but it won’t make the lack of waves feel any better.
We get a bit of a tease on Wednesday the 12th when the combined energy bumps up to 103 (moderate energy) with a 4 ft WSW swell, but it’s a cross-onshore wind and choppy, so the quality is gone. After that, it’s a long, slow slide into tiny, weak dribble. From Thursday the 13th right through to the end of the run, we’re looking at surf heights of 1 ft or less, mostly with periods that are too short to do anything, or very long-period groundswell that’s so small it’s a non-event.
There’s a few glassy moments on the mornings of Friday the 14th and Wednesday the 19th, and a clean offshore wind on Monday the 17th, but with a swell height of 0.3 ft, it’s flat. You could paddle around on a longboard, but you won’t be catching anything. The spot is inconsistent and sheltered, so this kind of blank run is more normal for this area.
There is one little flicker right at the end – on Friday the 21st of August, there’s a clean 3 ft pulse from the north with light winds, but the combined energy is only 27 (weak) and the period is a short 4 seconds. It’s not enough to change the outlook. The rest of the forecast is just tiny dribble and lumpy cross-shore winds.
Save your energy. The forecasts can change, but right now, there’s nothing to chase.

Information about the Seaford Reef Surf forecast
The above surf forecast table for Seaford Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Seaford Reef can be found by selecting the local surf guide option on the grey menu. Our Seaford Reef 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 (Seaford Reef) 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 Seaford Reef 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.
Seaford Reef is 7 km (4 miles) from the very large city of Morphett Vale. If you plan a holiday in Adelaide, look for hotels and other accommodation in Morphett Vale. Morphett Vale has rooms for a wide range of budgets as well as cheap car hire and transport links.
