The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for Seaford Reef.

Honestly, mate, I'm looking at a pretty flat spell ahead. The whole 16-day window is a struggle, with no real standout sessions. The water temp is sitting at about 58°, which is pretty much what you'd expect for this time of year, nothing unusual there.

We start off with a bit of a nothing-burger right from the get-go. Sunday morning, September 6th, we've got a tiny 1ft swell from the WSW, but it's getting chopped up by a cross-onshore wind. The combined energy is a weak 31, so there's just no power in the water. That theme continues right through the first week. Monday and Tuesday offer up nothing but ankle-snappers at around 0.3ft to 0.7ft, though a couple of those mornings have clean conditions. Tuesday morning, September 8th, is actually glassy, but with only 0.7ft on offer and a combined energy of 9, it's a lake, not a surf break.

The swell tries to pick up a touch on Wednesday, September 9th, with a 3ft pulse from the south, but the period is a short, weak 4 seconds, and it's accompanied by a 19 mph cross-offshore wind. That's a messy, blown-out combo, not worth getting wet for. The rest of that week and into the next just fizzles out again, with tiny waves and poor conditions.

We get another small bump around Monday, September 14th, with a 4ft swell from the west, but it's a full-on onshore wind at 16 mph, and the period is a terrible 5 seconds. The combined energy hits 70, which is still weak, and the onshore wind will just make it a bumpy, closed-out mess. That's the biggest swell of the whole run, but the quality is non-existent.

The last few days of the forecast, from the 20th of September, show a bit more life with 3ft to 3ft swells, but the wind is still a problem. The morning of Monday, September 21st, has a light cross-shore wind and a 3ft, 4-second swell (combined energy 39), but that short period won't give you any real shape. The afternoon of the 21st turns glassy with a 3ft, 5-second swell (combined energy 48), but it's still a weak, short-period wave.

Given the significant swell never really shows up, but when it does, the wind is onshore and the quality is poor, this setup is a classic reef that needs a proper, clean groundswell. A few of those days with onshore wind and a bit of size just look like a write-off for a paddle board. You'd be better off looking for something else.

The long and short of it is, there's nothing to recommend here. It's a long stretch of poor surf, with only a couple of days that are almost surfable. The breaks are inconsistent, and the forecasts can change, but for now, you're better off keeping the board in the car.

Rusty.

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.
