The Lowdown

Alright folks, Rusty here. Let’s be straight with you. If you’re looking at Seaford Reef for the next couple of weeks, you’re gonna want to keep your expectations in the gutter. The models are showing a whole lot of nothing for a long stretch, and when something does pop, it’s not looking pretty. We’re looking at a serious dry spell to start.

The first real chance of anything rideable doesn’t show up until Saturday the 8th. And even then, it’s a weak, short-period north swell pushing in at about 4ft. The morning has a bit of a clean look with a cross-offshore breeze, but it’s got that short, close-out energy to it. The combined energy is still weak, sitting at 53. Then the wind swings around and messes it up in the arvo. It’s not great. This is more of a "check it if you're desperate" situation than a "get amped" situation.

The surf slowly builds into Sunday the 9th, reaching 4ft, but the wind goes onshore and it gets lumpy with light rain. Energy bumps up a bit to 78, but the quality tanks. Monday the 10th morning pushes to 5ft with a bit more push, hitting a moderate energy reading of 176, but it’s still onshore and messy. Then Tuesday the 11th sees the biggest swell of this whole stretch, hitting 6ft. The energy jumps into the strong zone at 228, but it’s accompanied by rain showers and strong onshore winds. That’s a junky, blown-out mess, and at that size with this wind, it’s not a beginner wave. It’s a full-on grunt session at Seaford Reef, and honestly, it looks more interesting for the kite crew than anyone paddling out.

After that, it just fades away. The rest of the second week drops back down to under 3ft, with the swell direction swinging around and periods getting short and weak. There’s a bit of a glassy morning on Saturday the 15th, but the swell is only 0.7ft, with the swell period a long 8 seconds. There’s another glassy spell on Wednesday the 19th, but again, it’s tiny, with just 0.3ft on offer and a long period that will do nothing for this setup.

Overall, the takeaway is grim. This reef is sheltered and inconsistent at the best of times, and this forecast is a full-on blank run. We get a brief window of poor-to- average surf from the 8th to the 11th, and the only standout size-wise is that messy 6ft day on the 11th, which is a write-off for quality. If you’re a beginner, the small stuff won’t be worth the effort, and if you’re a expert, there’s nothing here to get you excited. It’s a waiting game, and with a forecast this flat, it’s going to take a lot of patience. Forecasts can change, but right now, I’d be doing other things.

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.
