The Lowdown
Alright, let’s get real about this surf outlook. The next 16 days are looking pretty flat and frustrating, to be honest. The first real bit of swell shows up on Wednesday, September 2nd, but it’s only a 0.3 ft bump from the SW, and the wind is blowing straight onshore at 15 km/h, so it’s a total loss. The next few days are just more of the same: tiny waves and poor wind.
Thursday the 3rd sees a little more size, about 4 ft from the west, but the wind is a messy cross-onshore, and the wave energy is weak (92). It’s not worth paddling out for. The entire first week is a washout with small, short-period slop.
There’s a moment on Saturday, September 5th that gets your attention, but it’s a bit of a trap. We get a solid 8 ft swell from the WSW, with a combined energy of 828, which is a lot of power. But the wind is screaming from the west at 40 km/h, straight onshore. That’s going to be a chaotic, blown-out mess. This is a reef break, so it’s not for beginners anyway, and at that size, it’s expert-only. The wind will ruin it for surfing, but it might be interesting for the kite crew.
Into the second week, the pattern stays the same: tiny swell for days, with the occasional pulse of short-period windswell. The best we see is on Wednesday, September 9th, with a 5 ft swell from the south in the afternoon, and a clean offshore wind from the ESE. The energy is moderate (142), and the period is short at 5 seconds, so it’ll be a bit weak, but it’s the cleanest wave of the entire forecast. It’s still only a 1 out of 10 on the quality scale, so don’t get your hopes up.
The very end of the run, on Thursday, September 17th, shows a consistent 5 ft SW swell with clean cross-offshore winds from the SSE. The energy is moderate (118), and it’s the most consistent-looking option in the second week. But again, it’s not a standout.
If you’re really jonesing for a paddle, the best bet is that Wednesday afternoon on the 9th, when the wind cleans up the 5 ft south swell. It’s not going to be epic, but it’s the only time the wind and swell line up in a way that’s worth a look. The rest of the period is a flat, windy mess.
The water is sitting around 59°F, which is about normal for this time of year, so you’ll still need a good wetsuit.

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.
