The Lowdown
Alright, I’m gonna put it in feet and miles for you. This is Rusty, and we’re looking at Seaford Reef for the next couple weeks. I gotta be honest – this is a dry spell. There’s no good surf on the cards, and it’s gonna be a long wait.
From Sunday the 9th, we’ve got nothing. The swell is flat, wind is blowing 15 to 19 mph, cross-shore and cross-onshore. It’s a mess. Water temp is about 57°, which is normal for this time of year, but that doesn’t help.
Tuesday the 11th is more of the same: lumpy, choppy, and the swell is tiny. The energy is low – under 75. The period is short, under 6 seconds. That’s just wind slop.
Wednesday the 12th has a little pulse – 4 feet from the WSW with a 6-second period, and the energy hits 104. The wind is offshore, which is a plus, but the poor surf quality comment means it’s not gonna be clean. Might be fun for a kite surfer, but not for paddle surfing.
From Thursday the 13th through the end of the first week, the swell drops to 1 foot or less. The energy is pitiful – single digits. The wind gets glassy on Friday the 14th and again on the 18th, but with no swell, it’s just a flat lake.
There’s a gap of almost two weeks with no recommendations. From the 9th all the way to the 24th of August, every single report says “poor surf conditions.” This spot is inconsistent and sheltered, so a blank run like this is more normal for the area.
The only hope is on Monday the 24th. We get a tiny bump: 2 feet in the morning, 4 feet in the afternoon, from the WSW and W. The energy is still low – 24 and 59 – and the period is short at 5 seconds. But the wind is light and cross-off to cross, so it’ll be clean. It’s a beginner-friendly reef, and with crowds listed as “often,” you might have company. But the waves are small.
This is a rough 16 days. The only faint glimmer is the 24th, and even then, it’s not a standout. But forecasts can change, so don’t give up.
This is Rusty, signing off.

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.
