The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for Seaford Reef over the next couple of weeks.
Honestly, mate, the outlook is a tough one. We’ve got a solid 16-day window, but there’s barely a whisper of rideable surf for most of it. The first real stretch from the start is a long, flat wait. From Wednesday the 26th of August all the way through to the end of the month, we’re looking at tiny, knee-high slop – 0.3 ft to 0.7 ft – with the combined energy barely registering (9 to 5 units of weak energy). The water temp is about average for this time of year, so no surprises there.
The only glimmer of something bigger shows up on Tuesday the 1st of September. The swell bumps up to around 3 ft from the north, but it’s a short-period, windswell of only 4 seconds, and the combined energy is still only moderate (37 units). The wind is a fresh cross-shore at 19 mph, making for lumpy, cross-chop conditions. It’s not clean, and it’s not quality. The swell direction from the north is far from the optimum for this sheltered reef, which really wants WSW. This setup is more interesting for a kite than a paddle.
After that, it drops back into the doldrums again. The rest of the first week of September and into the second week is a write-off – tiny 0.3 ft to 0.7 ft waves with mostly onshore or cross-onshore winds. The whole calendar is a flat run of "poor surf conditions" with no standout days. If you’re desperate, the morning of the 1st of September offers the most energy, but it’s a messy, short-period windswell that won’t shape up well. Seaford Reef rarely breaks as it is, and this forecast confirms it’s a quiet period for the spot.
The outlook is bleak, but the area is known for this. It tends not to stay poor forever, but for now, the only thing breaking is the wind.

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.
