The Lowdown
Alright, let’s get real about Seaford Reef.
Right now, things are flat. I mean, really flat. We’ve got a solid stretch of next to nothing on the cards, and it’s going to be a long wait. From the start of the period through the end of August, there’s just nothing worth paddling out for. Tiny dribbles of swell, barely registering on the energy scale – we’re talking combined energy values of 8 to 19, which is weak, weak, weak. It’s a full week of this quiet spell. A few mornings are glassy, like Sunday the 23rd and Monday the 24th, but with swell heights of 0.7ft or less, it’s a lake, not a surf spot.
The first real flicker of something happens on Tuesday the 1st of September. We see a bump to 3ft from the NNW, but it’s a short-period windswell (4 seconds) and the wind is howling from the N at 16 mph, cross-shore. It’s going to be choppy and messy. The combined energy climbs to 41, but that’s just the wind messing with the surface. Not a surfer’s friend.
The only time this place gets any real size is on Sunday the 6th and Monday the 7th of September. Sunday morning sees a jump to 6ft from the N, with combined energy at 166 – that’s moderate energy, finally. But here’s the kicker: the wind is onshore from the SW at 16 mph, creating a choppy mess. That swell is too big for beginners, and with onshore wind, it’s going to be a washing machine. Monday the 7th is even bigger, pushing 7ft from the W with energy at 294, but again, cross-onshore winds from the NW at 12 mph. For a sheltered reef like this, that onshore component is a dealbreaker. The wave direction doesn't match the optimum WSW either.
Honestly, there isn't a standout session in this whole outlook. It’s a bleak run. Seaford Reef is inconsistent at the best of times, and this forecast just doesn't line up. For the few days of size, the wind ruins it. If you’re desperate for a paddle, the glassy mornings with 0.3ft or 0.7ft are all you’re getting, but don’t expect a wave.
Stay patient, mate. Sometimes the ocean just says no.

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.
