The Lowdown
Alright folks, Rusty here. Let’s be straight with you about the next couple of weeks. It’s a tough one. We’ve got a long, quiet run ahead.
Looking over the whole 16-day window, there are no good waves on offer. The first solid chance doesn’t even pop up until Sunday the 20th, and even then, it’s nothing to write home about. From the start of the period all the way through to the 19th of September, the surf is flat or near-flat, with combined wave energy barely getting into double digits, maxing out at a weak 16. There’s a gap of about 5 days with absolutely no recommendations, and the models are showing just tiny, weak signals that won't do anything at the reef.
Heads up for Sunday the 20th. The swell nudges up a fraction, but it’s still a sad story. We’re looking at a 4ft SW windswell with a short 6-second period and combined energy of 94, which is still weak. And to make matters worse, we’ve got a moderate cross-onshore wind from the WNW at 16 mph, making it choppy and messy. The water temp is about average for this time of year, but you won't be in the water long enough to notice.
The rest of the outlook is more of the same. We see the occasional glassy morning on the 21st and the 22nd, but the swell is practically non-existent, with heights dropping to 0.3ft. The long period 18-second swell on Saturday the 26th has a bit of energy, coming in at 23, but the swell height is a mere 0.3ft, so it’s all show and no go.
Honestly, for Seaford Reef, this is a blank run. It’s an inconsistent spot that needs a proper WSW swell to line up, and we’re just not getting it. The light winds and calm spells would be beautiful if there was any wave to ride, but there isn’t. Not much for the paddle crowd here, and even a kite would be struggling.
Stay patient, keep an eye on the charts, and maybe give it a rest this week. Things can change, but right now, it’s a no-go.

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.
