The Lowdown

Righto, grab a coffee mate, let’s have a look at what’s comin’ through.

To be totally honest, we’re lookin’ at a proper flat spell here across the Seaford Reef region. There’s not a single standout session in the whole sixteen-day run. The swell energy just doesn’t build enough to get anything worthwhile, and what little bumps show up are plagued by poor surf conditions. Most days the combined swell energy sits in the weak range (under 100), with a brief flicker of moderate energy (119 to 128) around Thursday July 23rd and Friday July 24th, but even that tops out at a tiny 5ft with messy cross-onshore winds and lumpy, chopped-out conditions. That’s not surf, that’s a washing machine.

We kick off Thursday July 16th with glassy conditions and a tiny 0.7ft swell from the WSW – period is short at 8 seconds, so it’s barely a ripple. The water temp is about 58°, which is pretty normal for this time of year. That little pulse dies off into Friday July 17th and the weekend with swells dropping to 0.3ft. The winds stay light and mostly offshore or glassy Saturday morning, but there’s nothing to ride. Sunday July 19th sees a cross-shore breeze and the same 0.3ft dribble. Through Monday July 20th to Wednesday July 22nd, we get a slight lift to 0.7ft and then 3ft, but the period tanks to 4 seconds on the 22nd – just wind slop – and the wind shifts cross-on. Not worth paddling out.

Now here’s that brief flurry I mentioned: Thursday July 23rd pushes into 5ft with a WSW direction and period up to 6 seconds. The combined energy hits 119 to 128 (moderate) but the wind is a fresh 18–22 mph cross-onshore, making it lumpy and ugly. That 5ft with that wind and short period is more of a mess than a wave. Friday July 24th drops back to 1.0ft with moderate cross-onshore chop. Saturday July 25th cleans up a bit with light cross-offshore breezes and a rise to 3ft, but the period is 4 seconds – no push. Sunday July 26th gives us a glassy morning with 3ft at 5 seconds, which is the closest thing to a clean wave all run, but the period is too short and the energy is still weak (50). In the afternoon the wind goes onshore. That’s the best of a bad bunch – and it’s not saying much.

From Monday July 27th right through to the end on Friday July 31st, we’re back to 0.3ft to 1.0ft dribble, with light winds but no swell to speak of. Crowds are listed as “often” at Seaford Reef, but honestly, with surf this poor, you won’t have to worry about anyone else out there. This break is an inconsistent reef, and this forecast proves it – it’s a blank run that’s more normal for the area when conditions don’t align. Keep an eye on the forecast; it can’t stay poor forever.

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.

Seaford Reef is 7 km (4 miles) from the very large city of Morphett Vale. If you plan a holiday in Adelaide, look for hotels and other accommodation in Morphett Vale. Morphett Vale has rooms for a wide range of budgets as well as cheap car hire and transport links.
