The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the table for this neck of the woods over the next sixteen days.
We are looking at a pretty bleak stretch, to be honest. This spot is inconsistent and sheltered, and the swell just isn’t lining up. There’s a whole lot of nothing for a long time. We don’t see any decent surf until Tuesday, August 11th, and even then it’s nothing to get excited about. That’s over a week of flat and messy conditions to sit through.
Tuesday, August 11th, is the only time I’d even think about paddling out, and I’m being generous. Seaford Reef has a bit of life with a WNW swell coming in at 5 ft. The water temp is sitting at 57°, which is about normal for this time of year. The best part is that both morning and afternoon turn glassy. That’s a massive positive. The swell is short period stuff, only 5–6 seconds, so don’t expect any grunt. The combined wave energy is weak (119 in the morning, 201 in the afternoon). It’s surfable, but it’s very ordinary.
After that, it’s all downhill. Wednesday the 12th goes flat again, and then we get a pulse of bigger, messy swell from the 13th onwards, but it’s always accompanied by strong, onshore winds, making it a complete write-off for a surfboard. You’d need a kite to have any fun out there. Big numbers on the energy (1136 on the 9th for example), but that’s just brutal, blown-out power. Not for paddling.
So, the only true standout in this whole outlook is that glassy window on Tuesday the 11th. It’s a small window, the waves are average, but it’s the best you’re gonna get. Everything else is a hard pass.

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.
