The Lowdown
Right, this is Rusty, givin’ you the straight talk on Seaford Reef for the next couple weeks. It’s a skinny stretch, and that reef’s an inconsistent, sheltered one, so when it’s flat, it’s flat.
We’re kickin’ off with a real dry spell. From Monday the 24th through the end of August and into the first week of September, it’s pretty much a bust. The waves are tiny – 0.3ft to 3ft – and the combined swell energy is mostly in the single digits or low double digits (3 to 41). The swell periods are all over the place, but the direction is mostly off from the optimum WSW. The wind’s a mixed bag: some glassy mornings, but a lot of cross and cross-off with moderate to fresh breezes, especially on the 25th and 28th of August. Water temp is about average for the time of year.
The only real glimmer is way out there. Saturday the 5th of September shows a 3ft swell from the NNW, with a combined energy of 52 (moderate) and a short 5-second period. Wind is cross-on to cross, light to gentle, so it’ll be messy but not hopeless. Then Sunday the 6th has a tiny 0.7ft to 1.0ft pulse from the WSW, with moderate energy (28) and cross-shore wind. Still poor conditions, but it’s the best you’ll get.
Forget the rest. The 7th and 8th of September see a bit more size (3ft to 4ft) but it’s all onshore, fresh winds, and lumpy chop. That’s kitesurfing territory, not for a paddle.
Bottom line: leave the board in the truck for the next week and a half. Your only real shots are the 5th and 6th of September, and even then, you’re huntin’ for a knee-high ripple. No standout here. Just a quiet, flat spell that’s normal for this spot.
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.
