The Lowdown
Alright folks, Rusty here. Let’s be straight with you, this outlook for Seaford Reef is a tough one. We’re looking at a 16-day window that’s more about waiting than charging. There’s a real dry spell right out of the gate. The first good chunk of the forecast shows nothing but poor surf, so we’re looking at a gap of nearly a week before anything even gets close to interesting.
The entire period is plagued by small, weak swell with mostly cross-onshore or onshore winds. The water temp is sitting at 57°, which is pretty much normal for this time of year, so no surprises there.
The best bit of the whole run looks like it’ll be around Monday the 24th of August. The swell finally picks up, with a solid 6ft of W swell pushing in. The combined energy jumps to a respectable 245 (moderate wave energy), which is the most juice we’ll see all window. But, and it’s a big but, the wind is a cross-shore Moderate breeze from the NNW, so it’s going to be a bit messy with a cross-chop. The period is a short 6 seconds, so it’s not going to be the cleanest, but it’s the biggest we’ve got. If you’re an experienced surfer who can handle a bit of chop, that Monday morning might be worth a look. After that, Tuesday the 25th has some similar size, but the wind gets worse, turning onshore and lumpy.
Honestly, there’s no standout session here. The swell is too small and the wind is rarely playing ball. For a break that’s already inconsistent and sheltered, this is a real bummer. The rest of the window is tiny waves with clean conditions but no push. Looking at the setup with the bigger swell and poor quality wind, it might be more interesting for a kite surfer than a paddle surfer on the better days.
Keep your eyes on the charts, but for now, it’s a waiting game.
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.
