The Lowdown
Alright, Rusty here. Let’s keep it real. Seaford Reef is flat as a pancake for days. The first time you’ll see anything worth a look is Thursday, August 27. That’s a long stretch—about 11 days—of nothing.
Thursday, August 27 brings a pulse. Swell around 5ft in the morning from the NW, with an offshore breeze out of the ENE. Clean, but the energy is weak at 101. Afternoon goes glassy, but the swell drops to 4ft from the W. Still clean, still small. Surfable, but not a standout.
Friday, August 28 is similar. Swell holds at 6ft from the W, but the period is only 6 seconds—short-period wind swell, so the waves are soft. Wind stays cross-off from the NE/NNE, so it stays clean. Combined energy is moderate at 197–212. For a beginner reef that’s sheltered, it’s okay. Water temp is 57°, about normal.
The one true standout is Saturday, August 29, morning. Swell hits 8ft from the WSW, combined energy jumps to 548—strong—and the wind goes glassy. This is the best session by far. The swell direction matches the reef’s optimum from the WSW. The waves will have some punch, but with a 7-second period, it’s still short-period, so don’t expect long, lined-up sets. The glassy conditions will make the surface perfect. 8ft is solid—maybe too much for beginners, but for anyone with experience, this is the one to target. The afternoon turns onshore, so hit it early.
After that, it’s back to tiny. A 3ft morning on Sunday, August 30, then nothing. The reef is inconsistent anyway, so a long flat spell like this is normal around here.
Keep your eyes on that Saturday morning, August 29. That’s your best shot.
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.
