The Lowdown
Alright folks, Rusty here. Let’s be straight with you: this 16-day stretch for Seaford Reef is about as quiet as a flat day in the doldrums. There’s simply no good surf on offer. The whole forecast window is a big, fat zero in terms of rideable waves. You’re looking at a solid gap from now right through to the end of the period with nothing worth paddling out for.
The first few days are a dead loss. Thursday morning, August 6th, you’ve got a tiny 0.3ft ripple from the west with a short 5-second period and combined energy of just 1 – that’s weak stuff. The wind is light cross-shore, but with that size, it’s a non-starter. The afternoon goes glassy, but there’s no swell to speak of.
Friday and Saturday stay rubbish. A tiny 0.3ft to 0.7ft, with a messy cross-chop building through Saturday. By Sunday, August 9th, the wind cranks up to 28 mph from the WSW, cross-onshore, shoving a messy 6ft swell around with a combined energy of 245. That’s moderate energy, but the wind is stripping any chance of a decent wave. Monday, August 10th, isn’t any better.
The wave energy briefly spikes on Tuesday, August 11th, with a 7ft swell from the north, period of 6 seconds, and combined energy of 343. That’s moderate energy, but the wind is a strong cross-shore at 25 mph, creating a messy cross-chop. It’s a total write-off for a clean surf.
Then Wednesday, August 12th, the wind goes near gale from the west, eventually hitting 31 mph, and the afternoon sees a big, ugly 12ft swell from the WSW with a short 8-second period and combined energy of 1392 – that’s strong energy, but it’s a dangerous, blown-out mess. Only for experts with a death wish, and even then, the quality is zero.
The rest of the second week and into the third is more of the same. Tiny, weak swells, glassy mornings with no waves, or light winds on tiny, unrideable lumps. The water temperature here is 57°, which is about 1° cooler than average for this time of year – nothing unusual, just a bit nippy.
Look, this is a sheltered reef that’s inconsistent, and this forecast shows why. It’s a long, blank run. The only thing that might interest a surfer is a kite surfer, given the strong, cross-onshore winds on a few days with some size. But for paddle surfing, you’re better off finding a different hobby for a couple of weeks.
Keep an eye on it, but don’t hold your breath. Forecasts can change, but this one is stubborn.

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.
