The Lowdown
Alright, Rusty here. Let’s talk about what’s cookin’ for Seaford Reef over the next couple of weeks. I won’t sugarcoat it – this stretch is a flat spell in a sheltered spot, so the wait is real.
At Seaford Reef, we’re startin’ off with a whole lot of nothin’. From Sunday the 19th of July right through to Friday the 1st of August, the swell is tiny, mostly under 0.7ft, and the wind is cross or cross-on. The wave energy is pathetic – just single digits in the combined swell energy (9) making for poor surf conditions. It’s looking sad, really. Water temp is about 58°F, which is pretty much normal for the time of year, so at least the water’s not causing any extra drama. The break is inconsistent at the best of times, and this is a classic blank run for the area. It’s a begginer-level reef, but there’s just nothing to ride.
Finally, on Saturday the 1st of August, the morning shows a small pulse – swell bumps up to 5ft from the north with a short period (5 seconds), but combined energy jumps to 104 (moderate). The wind goes glassy, which could clean it right up. You’re looking at surfable waves but very ordinary conditions – I’d rate it a soft 1 out of 10. The swell direction is north, but this reef’s optimum is from the WSW, so it’s not really lined up right. Still, if you’re desperate for a paddle, that Saturday morning glass-off is your best bet. There’s no standout here – it’s one marginal moment across the whole two weeks.
The outlook picks up again Sunday the 2nd of August morning – glassy with 4ft from the NNW (period 5 seconds, combined energy 153, moderate), but by afternoon the wind swings, and it’s back to poor. Nothing to get excited about.
Truth is, it’s a long famine. The swell that shows up in the second week (around 4-5ft) is short-period wind swell, not any kind of groundswell, so it’ll be weak and messy. There’s a bit of energy behind it, but the timing and wind just aren’t on your side. The reef is sheltered from the north, so the swell’s wrapping in, but not well.
For the rare time it does anything, expect it to be a novelty wave – inconsistent and rarely breaking properly. Not a spot I’d be hauling the quiver for.
Signin’ off – 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.
