The Lowdown

Alright, let’s get this straight. I’ll level with ya – Seaford Reef is having a pretty ordinary run. There’s not much on offer worth paddling out for, especially right now. The whole outlook is grim for any decent waves, and you’re gonna be waiting a fair while.

Lookin’ at the next week, it’s real quiet. From August 28th right through to September 3rd, the swell is tiny, barely a ripple, with combined wave energy all under 50. You’ll see mostly 0.3ft to 3ft, and that only comes with poor form anyway. There are a few mornings where the wind goes glassy or offshore, but with no swell to work with, it’s a flat spell. A real frustrating stretch.

Now, heads up: around September 4th, there’s a bump. Friday morning the swell pushes up to 5ft from the west, with moderate cross-shore wind and energy hitting 169 (moderate). Problem is, the period’s only 6 seconds and it’s gonna be choppy and messy. Not great for paddlin’. That swell drops again quickly through the weekend, and the wind stays onshore or cross-onshore, so it’s not gonna be pretty.

Then you get a gap of flat or rubbish surf from the 6th through the 9th again.

But here’s the highlight – keep an eye on Thursday September 10th. Thursday afternoon things get interesting. We’re lookin’ at 10ft from the west, with a period of 7 seconds, and the combined energy jumps to 859 (strong). The wind is light cross-shore, so it stays fairly clean. That’s a serious amount of water moving. However, for this reef break, 10ft is big – that’s proper expert territory. Beginners will need to sit that one out. The swell direction is west, which doesn’t quite match the optimum of WSW, so it might not line up perfectly, but still – that’s the best energy we see all forecast. The morning before also pumps 5ft with 154 energy, but still cross-shore wind. Thursday afternoon is the standout, but remember this is over a week away, so long-range promise – less certain, but worth checkin’ back.

Seaford Reef is sheltered and inconsistent, so these weeks with no real surf are normal for here. The water temp ain’t anything wild this time of year, just about average. And if you decide to go out on those bigger, wind-affected days with poor quality, it might be more interesting for a kite than a paddle.

So bluntly: nothin’ now, a week of flatness, a brief pulse of moderate swell early September that’s blown out, and one big but expert-only day on the 10th.

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.
