The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
Well, to be straight with you, the next 16 days are looking pretty grim for Seaford Reef. We’ve got a long, flat stretch ahead with no real standouts to get excited about. The first week is basically a write-off, and the second week doesn’t offer much of a silver lining either. There’s a gap of about 10 days with no real surf to speak of before we see a pulse of size, but even then, the conditions are just not cooperating.
Saturday the 1st and Sunday the 2nd are a no-go: tiny, weak swell with poor wind. The swell is tiny, at 2 ft from the N, and the period is a pathetic 4 seconds. The combined energy is a measly 10, so there’s no power behind it. The wind is a messy cross-offshore, but it’s not enough to save it. The water temperature is 57°, which is about what you’d expect for this time of year.
The whole first week drags on with nothing but tiny, weak waves. The swell never gets above 5 ft, and when it does reach that on Sunday the 2nd, the period is still a short 5 seconds, and the wind is a fresh cross-onshore, making it a lumpy mess. The energy readings are all in the double digits, nowhere near enough to get a decent wave.
The only real event in the whole forecast comes around Monday the 10th of August. The swell jumps to 8 ft from the WSW with a period of 7 seconds. The combined energy is a hefty 605, which is strong, but the wind is a cross-shore breeze, and the surf quality is described as marginal. This is big, powerful surf, but it’s raw and unruly. At 8 ft, this is strictly for experienced surfers only, and even then, it’s a messy, challenging day. The period is short, so it’ll be a close-out, dumping wave, not the clean, lined-up stuff we love.
After that, the swell fades quickly through Tuesday and into the rest of the week, dropping back to tiny, clean but gutless conditions. The winds get light and glassy on Thursday the 13th and Saturday the 15th, but there’s no swell to work with, just 1.0 ft or 0.3 ft waves.
For a spot that’s inconsistent and sheltered, this is a pretty typical blank run. It’s not going to stay this poor forever, but for the next 16 days, there’s nothing to get the heart pumping.
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.
