The Lowdown
Alright, let’s get straight into it. There’s a long stretch here with barely a whisper of surf, and when it does show, it’s not much to write home about. The only spot on the radar is Seaford Reef, a sheltered beginner reef that’s inconsistent at the best of times. The water’s sitting around 57°, which is pretty much what you’d expect for this time of year, nothing weird going on.
The whole first week and a half is a write-off. From Tuesday 11 August right through to Wednesday morning 20 August, it’s all poor surf conditions with tiny, messy, or non-existent waves. The swell heights are mostly down around 0.3 ft to 1.0 ft, and the combined energy is pathetic – often single-digit numbers (6, 7, even 1). There’s a bit of a pulse on Wednesday 12 August morning with 4 ft at 6 seconds from the WSW and combined energy hitting 100, but the wind is a cross-onshore mess, so it’s choppy and lumpy. No good. Thursday 13 August and Friday 14 August have glassy moments but the swell is just 1.0 ft with weak energy (14 to 25). Not worth paddling for.
The first real glimmer comes on Thursday morning 20 August. The wind goes glassy, and there’s a pulse of 4 ft from the north, but the period is a short 5 seconds and the combined energy is only 82. The commentary says “surfable waves but very ordinary conditions.” That’s the closest thing to a highlight, but it’s still a very average, short-period windswell on a sheltered reef. For beginners, the size is fine, but it’s not going to thrill anyone.
After that, it’s back to tiny waves for days. The next notable bump is on Tuesday 25 August afternoon, with 3 ft from the NNW at 5 seconds, and combined energy at 61. Clean cross-off wind, but again, short period and weak. Then Wednesday 26 August morning picks up to 5 ft from the SW at 6 seconds, with combined energy climbing to 126 – that’s moderate energy. The wind is cross-off and clean, so it’ll be rideable, but the period is still short, so don’t expect any real punch. That afternoon, the wind swings cross-shore and the swell drops slightly to 4 ft, still moderate energy at 120, but the cross-shore breeze will chop it up a bit.
The standout: Honestly, the best on offer is Wednesday 26 August morning at Seaford Reef. 5 ft from the southwest, clean cross-off wind, and the biggest combined energy of the whole forecast at 126. It’s not a classic, but given the long drought, it’s the session to aim for. The swell direction is WSW, which is the optimum for this break, so it’ll line up reasonably well. Still, it’s short-period windswell, so expect it to be a bit lumpy and not overly powerful. For a beginner spot, it’s fine, but if you’re after quality, this isn’t it.
For the rest of the window, it’s mostly tiny, weak, and flat. Nothing else comes close. The long gap from the 11th to the 20th is brutal, and then after the 26th, it fades back to nothing. Frustrating stuff.

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.
