The Lowdown
Alright, let’s break down what’s cookin’ at Seaford Reef, and I gotta be straight with you—it’s been a quiet stretch.
### The Overall Pattern
Right now, it’s a tough scene. The water temp is around 57°, which is about average for the calendar, nothing wild. But the surf? You’re looking at a lot of nothing. For days on end, we’re dealing with knee-high slop—0.7ft to 1ft mostly—with short, weak periods and winds that are either onshore or sideshore. The combined wave energy is practically zero for the first 10 days, flickering up to only a few hundred units but never breaking into the moderate range. The run of flat, poor conditions stretches from now all the way through to the middle of next week.
### Where It Gets Slightly Interesting
The only real flicker of hope comes on Thursday, 27th August. That morning, the wind swings offshore from the east at 6 mph, giving us clean, glassy conditions. The swell is tiny though—just 1ft from the WSW at 8 seconds—so you’re scratching for a ride. Combined energy is a weak 30, but it’s the cleanest you’ll find. The break itself is an inconsistent reef, and it gets crowded often, so you’ll have to fight for the small, clean sets.
Toward Friday, 28th August, we see a bump to 4ft from the N, but the period crashes to 5 seconds. That’s a short, steep, lumpy wave. Friday afternoon turns glassy again with the wind going dead calm, but the swell is back down to 4ft. It’s surfable but nothing to write home about.
### The Long Shot
Further out, on the 26th, we get a 6ft pulse from the WSW with a little more period—7 seconds—and moderate energy of 265. But the wind is cross-onshore at 12 mph, making it choppy. That’s a big, messy closeout for a reef and way too sloppy for a good time.
For the most part, with such small waves and wrong winds, this whole stretch looks like it was made for a kite surfer rather than a dedicated surfer. No clean, long-period groundswell to get excited about.
That’s the story, folks. I wouldn’t hang the board up, but I’d keep an eye on the forecasts—it’s got to get better eventually.

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.
