The Lowdown
Right then, let’s have a look at what’s on offer for Seaford Reef. I’ve got to be straight with you – it’s a pretty bleak run ahead. This spot is a sheltered reef, best for beginners, and it’s prone to being inconsistent, so we need a good alignment of swell and wind to get anything going. Over the next 16 days, we just don’t have that.
We start off with a bit of a tease. On Friday the 4th of September, there’s a tiny 1 ft swell from the WSW with a 9-second period, but the energy is weak (25), and the wind is a messy cross-shore, so it’s just poor surf conditions. That’s the story for the first few days.
Saturday the 5th sees a jump in size, with a 7 ft swell from the W, but the period is a short 7 seconds, and we’ve got a 25 mph onshore wind. The combined energy is moderate (447), but it’s going to be a wind-blown mess. Poor surf conditions. This is not a day for a beginner – that’s too big for them, and the quality is awful.
After that, the swell drops right off. From Sunday the 6th right through to Saturday the 12th of September, we’re looking at tiny waves, mostly below 1 ft, with very weak energy – often in the single digits. The wind does offer some clean windows, like a glassy morning on Tuesday the 8th, but with only 0.3 ft of swell, it’s a flat, glassy lake, not surf.
There’s a brief pulse on Thursday the 17th of September – a 6 ft to 6 ft swell from the WSW, with a 6-second period, and the energy is strong (259 to 292). The wind is cross-offshore and clean. But those waves are going to be short-period, choppy, and powerful – definitely for experts only, and the forecast still says ‘poor surf conditions’. It’s not a standout.
The rest of the run is tiny, weak, and often windy. There are no good surf options in this 16-day window. It’s a blank run for Seaford Reef, which is a bit of a bummer, but for an inconsistent, sheltered spot like this, it’s not unusual. Things can change, but right now, I’d leave the board at home.

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.
