The Lowdown
G’day, Rusty here, and I’ve gotta be straight with you – it’s a lean run ahead for Seaford Reef. This is a sheltered, inconsistent beginner reef that’s real picky, and for the first ten days of this forecast, there’s nothing worth paddling out for. The energy just isn’t there, and what little swell shows up gets chewed up by unfriendly winds. We’ve got a dry spell from now through the 6th of September, with barely a ripple to get excited about.
From Thursday morning the 27th of August, it’s all tiny stuff – 0.7 ft from the WSW with a period around 8 seconds, but a north breeze puts a cross-shore chop on it. The combined energy is weak (12), and it’s just poor conditions. Friday and Saturday stay flat with 0.3 ft to 0.7 ft, glassy at times but no real push. Sunday the 30th is the same story – 0.3 ft, glassy morning, but the combined energy is a measly 5. Monday the 31st brings a tiny 1.0 ft from the NNW with a pathetic 3-second period, and a cross-on breeze. Not a chance.
Tuesday the 1st of September sees a bump to 4 ft from the north, but it’s short-period (5 seconds) and a 16 mph cross-shore wind chops it up. Combined energy climbs to 54, but still poor. Wednesday and Thursday stay messy with onshore winds and small swell. Friday the 4th has 3 ft from the WSW, but a 12 mph cross-on wind makes it choppy. Saturday the 5th afternoon finally shows a glimmer – 5 ft from the north, glassy wind, and combined energy hits 111 (moderate). The wave comment is “surfable waves but very ordinary conditions,” scoring a 1/10. It’s not great, but it’s the first real hint of something rideable. Still, for a beginner reef, it’s a pass.
Sunday the 6th of September is a write-off – 8 ft from the WSW, but a 19 mph onshore wind and combined energy of 558 (strong) means it’s too big for beginners and blown out. Monday the 7th drops back to 1 ft, glassy, but combined energy is 75 (weak). Then, on Tuesday the 8th of September, we get our one standout. The morning shows 8 ft from the WSW, 7-second period, glassy calm – combined energy is 603 (strong). The afternoon holds 7 ft, still glassy, with energy at 407. The wave comment says “expect good surf conditions,” scoring a 2/10. For this spot, that’s about as good as it gets. That 8 ft is gonna be a solid, powerful wave for an expert, but it’s over 8 ft, so it’s expert-only. The glassy wind here is a major positive – clean faces all day. The swell direction is WSW, which matches the optimum for this reef. Just be aware it’s inconsistent, and with a 7-second period, it’s a short-period swell, so the waves will be a bit crumbly, but for a reef setup, it’ll still offer some fun. Crowds are often, so you won’t be alone.
After that, Wednesday the 9th and Thursday the 10th drop back to tiny 1.0 ft with cross-shore winds, and the energy falls off a cliff. It’s a short window, and then it’s back to the flat spell.
So, the best on offer is Tuesday the 8th of September – that’s your day. Get on it early for the cleanest conditions. Everything else is a waiting game. Rusty out.

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.
