Alright, let’s get straight into it. The outlook for Seaford Reef is a tough one, mate. We’re looking at a long stretch of small, weak, and mostly messy conditions. The whole 16-day window is a bit of a struggle, with no real standouts to get excited about.

First up, the water temp is sitting around 58°F – that’s about 1°F cooler than normal for this time of year, so nothing too wild, just a touch on the chilly side.

The first real chance to even think about a paddle comes on Sunday the 12th, but it’s not pretty. You’ve got a 5ft swell from the west, but it’s a short-period, wind-affected mess with a 19 mph onshore wind. The combined energy is moderate at best (200). That’s a no-go for a clean wave. Monday the 13th is similar – small, onshore, and poor.

Tuesday the 14th drops right down. The morning has a tiny 3ft west-southwest swell with a light cross-onshore breeze, but it’s just not enough to get the heart pumping. The energy is weak (38). By the afternoon, it’s even smaller.

Wednesday the 15th and Thursday the 16th see the swell bottom out – we’re talking 1.0ft or less. The wind goes glassy for a bit, but there’s simply no wave to ride. The energy is pitiful (12 and 6).

Friday the 17th and Saturday the 18th are flat and forgettable. The swell is barely a ripple, and the energy is in the single digits.

Now, Sunday the 19th shows a bit of a pulse. The swell jumps to 5ft from the north, but the wind is a fresh cross-shore at 19 mph, making for lumpy, choppy conditions. The energy climbs to 106 (moderate), but the quality is poor. It’s the kind of day that might look more interesting for a kite than a surfboard.

Monday the 20th has a similar story – 4ft from the west-southwest, but with a cross-shore wind and a messy look. Energy is moderate (128).

After that, the rest of the run from the 21st through to the 27th is a desert. Tiny swell, clean glassy mornings but no wave height, and very low energy. The 25th does have a very long-period 16-second swell from the southwest, but it’s only 0.3ft. That’s a tease, not a wave.

So, to be honest, there’s nothing here that’s worth a special trip. Seaford Reef is an inconsistent, sheltered reef break, and this forecast shows exactly why. The best you can hope for is a very small, clean wave on a glassy morning, but even then, you’ll be fighting for a ride. If you’re determined, keep an eye on the 19th or 20th, but manage your expectations. This is a lean period.

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.
