Alright, this is Rusty, and I’ve looked over what we’ve got for the next couple of weeks. Gotta be straight with you—this is a lean stretch. Real lean. We’ve only got one spot on the radar, Seaford Reef, and it’s a sheltered, beginner-friendly reef break that’s inconsistent at the best of times. Right now, it's mostly flat or just offering tiny, weak waves with poor surf conditions. There’s going to be a long gap with almost no surf worth paddling for, so let’s walk through it.

Right off the bat, from Sunday the 5th through to Thursday the 10th of July, it’s pretty grim. We’re looking at swell heights around 0.3 ft with combined energy values between 1 and 19—that’s weak, barely a ripple. Winds are light and variable, some glassy moments Monday afternoon and Thursday afternoon with WSW or NW winds under 3 mph, but even with clean conditions, there just isn’t any wave to ride. It’s a classic case of “flat and friendly.”

Then we hit a bit of a bump on Saturday the 11th of July. The swell bumps up to 5 ft from the WSW, but it’s short-period windswell at 6 seconds, and the combined energy sits at 142 (moderate). Problem is, the wind is howling onshore from the WSW at 19 mph, making it a messy, lumpy affair. Not good for surfing—more of a kite-surfing kind of setup if you ask me. That trend continues through the 12th to the 14th, with onshore and cross-onshore winds from the W and NW, swell dropping fast, and energy falling into the single digits. Poor conditions all round.

There’s a bit of a lull again until Friday the 17th of July, when we see another pulse. Swell from the NNW at 3 ft to 5 ft, period still short at 4-5 seconds, energy 38-98—moderate at best. Winds are cross-onshore from the NNW and NW around 12-16 mph, keeping the surface choppy. Still not great for a clean surf.

The biggest event in the whole outlook shows up on Saturday the 18th of July. We get a 6 ft swell from the WSW, with a combined energy of 244 (moderate to strong). That’s the biggest we’ll see in the whole 16 days. But—and there’s always a but—the wind is cross-onshore from the SW at 12 mph, so it’s going to be choppy and messy. The period is only 6 seconds, so it’s windswell, not a clean groundswell. This is really only for experienced surfers who don’t mind a battle with the chop. Beginners should stay well clear; it’s too big and ugly.

After that, from Sunday the 19th into Monday the 20th of July, it fades back to 2 ft and below, with onshore and cross-onshore winds, and the energy drops to 20-43. Back to the flat spell.

Overall, there’s no standout session here. The best we can say is if you absolutely need to get wet, Saturday the 18th offers the most swell, but it’s far from clean. The rest is a whole lot of nothing. For a reef break that’s already inconsistent, this is a pretty normal dry spell. Forecasts can change, but right now, don’t hold your breath. Keep an eye on the sky and the wind; sometimes a surprise glass-off can save a flat day, but that’s about it.

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.
