The Lowdown

Alright mate, Rusty here. Let’s be straight with you—this stretch isn’t looking like a classic. We’ve got a solid 16-day window ahead, but it’s mostly a write-off for anything decent. There’s a big gap right at the start with no real surf to speak of, and it doesn’t really get going until we’re well into the second week.

Seaford Reef is a sheltered reef spot, best for beginners, and it’s inconsistent. The water temperature is about what you’d expect for this time of year, nothing unusual. The whole first week is a dud. From Monday 31 August right through to Sunday 6 September, the swell is tiny, mostly under 3 ft, with short, weak periods and combined energy barely cracking 1 (yes, 1). The wind is all over the shop—cross, onshore, glassy—but it doesn’t matter because there’s no wave energy. The score is a flat zero the whole time. You’d be better off waxing your board and looking at the forecast.

There’s a bit of a pulse on Saturday 5 September morning, with a 5 ft swell from the WSW and a period of 6 seconds, combined energy at 195 (moderate), but it’s blowing onshore at 22 mph. That’s messy, lumpy, and not worth paddling out for. The surf quality is still poor.

The next real chance comes on Tuesday 8 September morning. We get a 5 ft swell from the WSW, period 6 seconds, and combined energy up to 164 (moderate). The wind is onshore from the west at 12 mph, which isn’t ideal, but it’s the biggest, most energetic swell of the whole run. Still, it’s a short-period swell and the break is sheltered, so don’t expect much shape. This one’s for the patient beginner who doesn’t mind a bit of chop.

After that, it drops off again. The rest of the second week shows tiny swells, glassy conditions, and combined energy as low as 7. There’s a long-period spike on Friday 11 September morning—a 0.3 ft swell from the SW with an 18-second period, but that’s just a ripple. Combined energy is 20. Hardly surfable.

The only other standout is Sunday 13 September afternoon. We get a 0.3 ft swell from the SW with an 18-second period, combined energy 24, and glassy conditions. Again, tiny. Not worth the drive.

Honestly, this is a poor run. If you’re desperate, the best of a bad bunch is Tuesday 8 September morning—it’s the only time we see a swell over 5 ft and moderate energy. But with onshore wind and short period, it’s not going to be a classic. For everything else, leave the board at home.

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.
