The Lowdown
Alright team, Rusty here again with the same story in feet and miles. Looking at Seaford Reef, the outlook across these 16 days is a quiet one. The swell stays tiny, and the good conditions are few and far between.
From Saturday the 12th of September, the swell is basically flat at 0.3ft from the SW. There’s a glassy period in the afternoon with light west wind, but with combined swell energy at only 8, it’s a non-starter. Sunday the 13th kicks up some wind but the swell is just wind chop at a 4-second period. Monday keeps it small and onshore, combined energy in the 30s—still weak.
Wednesday the 16th morning offers clean offshore wind, but the swell is only 0.7ft with a 9-second period. That long period would be great for a reef, but there’s no push. Combined energy is just 15. The rest of the week stays tiny and clean but powerless.
By the weekend of the 19th and 20th, the wind picks up and combined energy hits 69 on Sunday morning with swell up to 4ft, but it’s onshore and lumpy. That’s more of a kite-surfing breeze than a surfing wave.
Through to Sunday the 27th of September, the biggest we see is 4ft from the north with a short 5-second period and combined energy of 54. Water temp is about average for this time of year.
Seaford Reef is an inconsistent, sheltered beginner reef, and there’s no real standout window in this whole 16-day stretch. If you’re desperate, Wednesday the 16th morning is the cleanest but you’ll barely get wet. It’s a long dry spell ahead, but forecasts can always change.
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.
