Table - best surf conditions forecast for Seaford Reef over the next 16 days.
G’day, I’m Rusty. Let’s be straight with you – this outlook is a tough one. Seaford Reef is a sheltered reef break that’s inconsistent at the best of times, and looking ahead over the next 16 days, there’s just nothing worthwhile on offer. The whole period is a write-off for surf, so if you’re dead set on getting wet, this stretch of coast is not the place.
We’re starting from Thursday, 9 July, and right through to Friday, 24 July, it’s a flat, frustrating run. The first week is particularly grim. Thursday morning has a tiny 0.3ft swell from the SW with a 10-second period, but with a light cross-off breeze it’s clean, yet the energy is barely a whisper (4). The afternoon goes glassy, but the swell is still just 0.3ft. Friday sees a bit of a long-period 16-second groundswell, but it’s only 0.3ft, and a cross breeze doesn’t help. The real kicker comes Saturday, 11 July, when a 6ft to 8ft NW swell arrives, but the period is a short, crumbly 5-7 seconds, and 25 mph cross-on winds rip it to shreds. The energy spikes (194 to 720) but the surf quality is junk – it’s more of a kite day than a paddle day. Sunday and Monday stay messy with onshore winds and lumpy conditions, and by Tuesday, 14 July, the swell drops back to 2ft or less.
The second week doesn’t get any better. From Wednesday, 15 July, through to the end, we’re stuck with tiny 0.3ft to 1.0ft swells and occasional glassy mornings, but there’s no push. The energy is pitiful, often in single digits (1 to 12). Even the longest period swells (14-16 seconds) are too small to do anything. By Saturday, 18 July, a 4ft WNW swell shows up, but it’s cross-shore and lumpy, and the crowd profile at Seaford Reef is “often” busy, so you’d be paddling for nothing. The whole 16-day window is a blank run, and for a spot that’s already inconsistent, this kind of drought is more normal than unusual. Keep the board in the car, mate – forecasts can change, but right now, there’s nothing to chase.
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.
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.
