The Lowdown
Alright, this is Rusty, and I gotta be straight with you. Looking at the charts for Seaford Reef, it's a pretty grim outlook for the next 16 days. We're talking about a spot that's already inconsistent and sheltered, and this forecast isn't throwing us any bones.
The entire run is a bit of a bust. The swell is just tiny for the first week, and even when it does try to pick up, the wind is blowing straight onshore, chewing it all up. You're looking at a solid run of days with no real surf to speak of.
For the first few days, from Tuesday afternoon, the 4th of August, through the weekend, we're stuck with tiny, weak waves. The best we see is on Thursday morning, the 6th, with a 1ft swell from the west and a slight air, but it's cross-shore and the energy is basically nothing. It's just not enough to get excited about.
There's a pulse of bigger swell that hits around the 9th of August. Sunday morning sees a 6ft swell from the west, but it's being smashed by a 25 mph onshore wind. The combined energy jumps up to moderate, but the conditions are just ugly. It gets bigger, hitting 8ft Sunday afternoon and 10ft on Tuesday, the 11th of August, but that's all with strong onshore winds. This is not surfable, this is a washing machine. For a reef break, that's a total no-go. At that size and with that wind, it's more of a kite-surfing situation than a paddle session.
After that big blow, we drop right back down to tiny waves for the rest of the run. The 17th of August has a moment in the afternoon with glassy conditions, but the swell is only 0.7ft. It's a perfect day for a flat paddle, but not for surfing.
Honestly, there's nothing here that's a standout. The best on offer is a sad, tiny, weak wave on Thursday morning, the 6th, but even then it's not clean. We're looking at a long stretch of flat to poor conditions. For a place like this, which is already inconsistent, a blank run like this is more normal than not. The water temp is about 57°, which is pretty standard for the time of year. Don't hold your breath, the forecasts can change, but right now, this is a total write-off.
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.
