The Lowdown
Alright, Rusty here. I’m not gonna sugarcoat it: Seaford Reef is looking like a flat spell for the next two and a half weeks. There’s a big gap at the start where you won’t even see a ripple worth paddling for.
From Saturday 29 August through the end of the month, it’s pure ankle-biters. Swell heights are 0.3 ft, combined energy is barely a whisper (4 or less). The water temp is normal for this time of year, nothing special.
Tuesday 1 September throws a short-period windswell at 3 ft, but it’s got a 4-second period and a nasty 19 mph cross-shore wind. The ocean will be lumpy, cross-chop – more of a kite-surfing day than a paddle-surfing one. The combined energy is still weak (30).
The pattern stays messy for days. Onshore winds and bumpy conditions. Thursday 3 September sees a 3 ft swell, but it’s still short period and blown out.
The one real spike hits Monday 7 September: a S’ly swell of 6 ft with a 6-second period and combined energy of 216 – moderate power. That’s the biggest wave of the whole run. But the wind is cross-shore at 9 mph, keeping it from being clean. It’s the best of a bad bunch, but not a classic.
After that, it’s back to tiny, weak waves and poor conditions.
Bottom line: Monday 7 September morning has the most size (6 ft from the S), but don’t expect it to be glassy. For the rest, leave the board at home. This is a long, quiet stretch. Forecasts can change, but right now it’s a bust.
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.
