The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day outlook for Seaford Reef is about as quiet as a flat day in January. We’ve got a long, long stretch of tiny surf and poor conditions before anything even thinks about showing up. The first sign of any real swell doesn’t start appearing until around the 27th of July, and even then, it’s nothing to write home about.
For the first week and a half, from Friday the 17th right through to Monday the 27th of July, it’s basically a write-off. Swell heights are hanging around 0.3 ft to 0.7 ft with weak wave energy, mostly under 15 (combined energy of all swells directed here). The water temperature is about 58°F, which is pretty normal for this time of year – nothing unusual there. Winds are mostly light and cross-shore or cross-off, but with waves that small, it doesn’t matter. It’s a glassy, clean lake most days, but there’s just no push. You’d be better off with a paddleboard or a kite if the wind picks up, because this reef isn’t offering anything for a surfer.
Come Wednesday the 22nd and Thursday the 23rd, we see a tiny bump to 2 ft to 2 ft, but with a short period of 4 seconds – that’s just wind chop, not real swell. The energy barely cracks 15, and the wind is onshore or cross-on. Not worth a look.
The real standout, if you can call it that, is Monday the 27th of July into Tuesday the 28th. On Monday afternoon, we finally get a little pulse: 3 ft from the WNW with a 5-second period, and the combined energy hits 37 – still weak. Tuesday morning’s got a bit of size but then the wind cranks up to 19 mph from the NW, making it lumpy and cross-on. The swell direction is WSW, which is actually the optimum for this reef, but the short period and wind kill it. This is a beginner reef and it’s inconsistent, so a 3 ft wave with a messy cross-on breeze isn’t going to give you much. It’s more of a kite day than a surf day, honestly.
After that, the rest of the month into August 1st is just more of the same – tiny, messy, and weak. No real standouts here. The best advice I can give is to wait for a better forecast because this run is a dud. Seaford Reef is a sheltered spot, and when it’s on, it can be fun for beginners, but right now, it’s just not happening.
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.
