The Lowdown
Alright, let me take a look at what we’ve got for Seaford Reef over the next couple of weeks. I’m not gonna lie, this stretch is looking pretty grim for a paddle. The water temp is sitting around 58°F, which is pretty much what you’d expect for this time of year – nothing weird there.
The first real chance of any surf doesn’t show up until Monday, July 27th. That’s a solid week of flat, weak, or just plain messy conditions before we see anything. Even then, it’s not great.
Starting Monday, July 27th, we see a push of swell, but it’s coming from the NNW around 6ft with a short period, so it’s gonna be a bit of a jumbled mess. The wind is light, going cross-shore to cross-onshore, so the surface might not be too chopped up, but the wave quality is still rated poor. The combined energy, while moderate at 141-182, isn’t translating into good shape here. This setup is really more interesting for kite surfing than paddle surfing.
Tuesday, July 28th drops a bit in size, back to 4-5ft, but the wind picks up from the north at 15 mph, making it cross-shore and choppy. The energy is still moderate (98-110), but the conditions are messy. After that, it fades out fast.
From Wednesday, July 29th right through to the end of the forecast, we’re back to tiny, weak surf, a lot of onshore or strong winds, and generally poor quality. The first few days of August show almost nothing on the energy scale, with a couple of glassy moments on the 4th but with a tiny, short-period 1ft wave. It’s a long blank run for any decent ride.
Honestly, for the next 16 days, Seaford Reef is a write-off for a proper surf. It’s one of those stretches where the forecast can change, but right now, there’s nothing to get excited about.

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.
