The Lowdown
G’day, Rusty here. Let’s be straight up – if you’re after a session at Seaford Reef, this outlook is a tough one. There’s barely a ripple worth paddling for over the next 16 days. The whole run is pretty much a write-off, so don’t be holding your breath.
We kick off Sunday the 30th of August with nothing – just 0.3ft of weak, messy swell from the SW, and a 3 mph ESE breeze keeping it clean but tiny. Combined energy is only 5, which is basically nothing. Monday the 31st is more of the same: 0.3ft and glassy by the afternoon, but still no wave to speak of.
Tuesday the 1st of September sees a pulse of windswell jump to 4ft from the N, but the period is a shocking 5 seconds – short, fat, and running straight into a 19 mph cross-shore breeze. Energy hits 69, but it’s lumpy, messy, and poor. Not worth a look.
The rest of the week stays grim. Wednesday the 2nd through to Friday the 4th offer junk – onshore winds, small inconsistent waves, and poor surf conditions across the board. By Saturday the 5th, a bigger swell tries to show up: 6ft from the WSW with 28 mph cross-onshore winds. Energy climbs to 265, but that’s just messy, blown-out junk.
Sunday the 6th of September brings the biggest swell of the window: 8ft from the W, period 7 seconds, but with onshore winds and energy at 636. It’s too big for beginners and only for experts, but with that onshore wind, it’s a battle. The following Monday the 7th hits 10ft from the WSW – energy at 1181 – but again onshore and ugly. This one’s more for kite surfers than paddle surfers, honestly.
After that, it slowly fades. Tuesday the 8th stays chunky but choppy, and by Wednesday the 9th we’re back to small 3ft junk. The final days from the 10th to the 14th of September are tiny, weak, and mostly wind-affected, with occasional glassy moments but no real surf.
Water temp is about average for this time of year, so no surprises there. Look, it’s a barren run. Seaford Reef is a sheltered, inconsistent reef that rarely fires, and this forecast proves it. A blank run like this is more normal for the area, but forecasts can change – don’t give up hope entirely.
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.
