The Lowdown
Alright, let’s have a look at the charts for Seaford Reef over the next couple of weeks.
To be straight with you, it’s a long, quiet stretch. We’re talkin’ a big gap of almost nothin’ to get stoked about. The first several days and deep into the second week are flat. There’s really only one tiny moment where it might get a little interesting, but even that’s a stretch for a beginner-friendly, inconsistent reef. This spot is sheltered and needs a WSW swell to work, and we just aren’t seein’ the right juice.
Water temp is about average for this time of year, so no surprises there.
The whole first week, from Tuesday the 25th of August right through the end of the month, is a total wash. Tiny waves – 0.3ft to 4ft, but the bigger stuff on the 25th is messy, short period windswell (5-6 seconds) and torn apart by strong cross-shore winds. The combined energy is weak, barely hittin’ 88 on Tuesday, and it drops to single digits after that. We get some glassy conditions on the 26th and again on the weekend, but there’s zero swell to go with ‘em.
The first few days of September aren’t any better. There’s a little bump on Tuesday the 1st of September, with 2ft from the north, but with a period of just 4 seconds, it’s weak and lifeless – energy at 15. It goes glassy that afternoon, but the swell is already fadin’. After that, we’re back to micro stuff for days.
Now, the only thing that even looks like a standout is way out on Sunday the 6th of September. We see 5ft of west swell in the morning, with a combined energy of 154, which at least gets into moderate territory. But the bummer? The wind is straight onshore at 9 mph, and the period is still a short 6 seconds. That’s gonna be a lumpy, choppy mess. It’s too big for a beginner on a reef, and the poor quality makes it only for the die-hards. The afternoon drops off again. Not really a day to recommend, just the one with the most grunt.
So, the bottom line? There’s genuinely no good surf in this whole 16-day window. It’s a dry spell, and for a sheltered spot like Seaford Reef, that’s pretty normal when the swell direction doesn’t line up. We’ll just have to wait for the next system to push some proper south-west groundswell our way.

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.
