The Lowdown
G'day, I'm Rusty, and I've got the surf outlook for our local patch. I'm looking straight at the charts, and I've got to be straight with you—it's a tough run ahead. Seaford Reef is the only spot in the game, and it's a sheltered, inconsistent reef break that's usually best for beginners. Right now, there's honestly nothing worth paddling out for across the entire 16-day window. The first few days are a write-off with weak, choppy conditions, and it just doesn't improve.
Starting off on Tuesday morning, the 1st of September, there's a small 4 ft swell from the north, but it's short period, around 5 seconds, and a cross-shore wind at 19 mph is making it lumpy. The combined wave energy is a weak 53, and the water's sitting at 59°, which is about average for this time of year. It's a no-go. Tuesday afternoon eases up to a 3 ft NNW swell, but it's still poor. Wednesday the 2nd is flat with a tiny 0.3 ft swell onshore, and that sets the tone. Thursday the 3rd sees a bump to 4 ft from the west, but it's a cross-onshore chop with moderate energy at 122—still no good. The weekend brings some clarity, with Saturday the 5th showing a 5 ft WSW swell, but it's blowing onshore at 22 mph, making it a mess. Sunday the 6th has clean cross-offshore winds, but the swell drops to 1.0 ft, so it's all show and no go.
Into the second week, it's a desert. Monday the 7th has a 5 ft SW swell with a cross-shore chop, but the quality's terrible. From there, it's flat and fading. The 9th of September sees a glassy morning with a 0.3 ft swell from the southwest, but it's a long period of 16 seconds, giving it barely any energy (24). It's a novelty at best. The rest of the run through to the 16th is tiny, with waves under 3 ft, and most days are clean but completely flat. The combined energy rarely cracks 100, and it's often in the single digits. For a spot that's already inconsistent, this is a proper blank spell. If you're a kite surfer, the stronger winds on the 4th, 5th, and 12th might look interesting, but for paddle surfing, it's a no-brainer—leave the boards at home.

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.
