The Lowdown
Right, mate, Rusty here. Let's have a look at what's on the table for the local stretch.
Honestly, it's a bit of a grim outlook for the next 16 days. The finder's got nothing flagged as a recommendation, and the guidance confirms Seaford Reef is an inconsistent, sheltered beginner reef that rarely turns on. We're looking at a long, flat run with nothing worth paddling out for. The overall pattern is a whole lot of nothing, with a few pulses of windswell that are completely blown out.
The first sniff of any size comes on Monday the 10th of August, with the morning seeing a 6ft swell from the SW, but the combined energy is only moderate at 269. The problem is a fresh 19 mph cross-onshore wind from the WSW, making it a lumpy, poor session. That afternoon, the wind swings straight onshore and the swell drops to 3ft. Not worth a look.
There's a similar pulse on Wednesday the 12th of August – a 6ft WSW swell with 237 units of energy, but again, straight onshore wind at 22 mph. The afternoon is a bit cleaner but still onshore with a 5ft swell. The water temp is about 57°, which is a touch cooler than normal for this time of year (anomaly of -1°), but it's not unusual.
After that, it's a slow slide into tiny, weak surf for the rest of the week and into the second week. The 16th of August sees a very long-period 14-second groundswell, but it's barely 0.3ft. That long period would be a dream for a point or reef, but there's no energy behind it. The 19th of August has a 5ft pulse from the north, but it's cross-onshore and choppy.
The only bright spot, if you can call it that, is the morning of Saturday the 15th of August. The swell is a pathetic 0.7ft from the WSW, but the wind is glassy – a 3 mph SW breeze. It'd be a flat, glassy lake, not surf. The following days see some clean, offshore conditions with tiny, unrideable swell. Late in the period, the 21st of August morning has a clean 1.0ft swell with a gentle cross-offshore breeze, but it's just too small.
For a reef that's already inconsistent, this is a normal blank run. The forecasts can change, but right now, there's nothing to get excited about. The setup looks far more interesting for a kiteboarder on the days with wind and a little bit of bump, but for a paddle surfer, it's a hard pass.
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.
