The Lowdown

Alright, Rusty here again, swapping over to feet and knots for you.

Let’s be honest, Seaford Reef is not playing ball at all over this whole stretch. It’s a sheltered, inconsistent reef that needs everything to line up, and nothing is coming together. There’s a long, dry gap right from the start.

The first week is a total loss. From Monday the 14th through Saturday the 19th, we’re looking at swell barely reaching 3 ft, with periods hanging around 4-6 seconds. The wave energy is pathetic – in the teens and twenties, peaking at only 99 on Saturday the 19th. Winds are mostly onshore or cross, and on Tuesday the 15th a fresh breeze chops it all up. There’s a glass-off on Thursday the 17th morning, but with only 0.3 ft of swell and an energy reading of 3, you could waterski and not catch a wave.

Into the second week, it doesn’t get better. Sunday the 20th brings the biggest swell of the whole period at 6 ft from the WSW, but it’s a short-period 6-second windswell, and it’s being hammered by an onshore wind at 18 mph. The combined energy hits 187, but it’s a messy, blown-out heap of water. After that, it’s back to tiny, weak leftovers. On Monday the 21st, we get a brief offshore breeze from the east with 1 ft swell from WSW, and a clean surface, but the energy is only 33 – too small to bother.

From Wednesday the 23rd right through to Tuesday the 29th September, it’s all sub-2 ft slop with energy dropping to single digits. Winds are onshore or cross-onshore most of the time. There’s a glassy moment on Saturday the 26th morning with 3 ft of 5-second swell from the WSW, but with a weak 42 energy and the wind turning cross-onshore by afternoon, it’s a dud.

This reef is a tricky, rarely-breaking spot, and this run is a classic washout. There are zero standout sessions – nothing that would get a surfer out of bed. No good waves, no clean windows, just a lot of nothing. Forecasts can shift, but right now, it’s a solid bust.

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.
