The Lowdown
Alright, let’s have a look at the next couple of weeks.
To be straight with you, the surf is pretty much flat out there for a long stretch. We’re looking at a barren run for the first week to ten days, with nothing but ankle-biters and knee-high slop. The energy just isn’t there. Sure, you’ll get a few clean mornings, like the glassy spell on Monday the 21st, but with waves around 1ft and barely any push, it’s not worth getting wet unless you just want to bob around.
That Tuesday the 22nd has some promise with a light offshore breeze in the afternoon, but the swell is still tiny. It’s going to be a frustrating wait.
Now, here’s the glimmer. Things start to wake up on Sunday the 27th. The morning is still small, but that afternoon a new WNW swell starts to show, pushing 4ft with a 5-second period. It’s messy and jumbled, but it’s a start. The energy is still moderate at 66, so don’t get too excited yet.
The real standout, if we get lucky, is Monday the 28th. That’s the day to keep an eye on. Overnight the swell builds to a solid 5-6ft from the west with a 6-second period. The combined energy jumps right up to 205, which is the strongest we’ve seen all window. The wind is offshore, clean out of the ESE at 12-15 mph, keeping the faces reasonably tidy.
Now, Y-Steps is a fairly exposed setup, so it’ll catch this west energy, but that short period means it’s going to be a bit lumpy and could close out in places. It’s not a classic point-break wave, so it might not be its finest hour, but it’s the best on offer. The afternoon settles a bit to 4ft, still clean and offshore. This is the pick of the bunch for the whole two weeks, but I’d still call it promising rather than perfect. With the short period, this is one for the more experienced crew, not the beginners.
After that, it fades away fast, dropping back to nothing by Tuesday the 29th. So don’t sleep on that Monday – it’s a one-day wonder, and then we’re back to the flat spell.
Water temp is sitting around 59°, which is pretty much normal for this time of year.
So, mark your calendar for Monday the 28th. It’s not going to be epic, but it’s the only real shot we’ve got.

Information about the Y-Steps Surf forecast
The above surf forecast table for Y-Steps provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Y-Steps can be found by selecting the local surf guide option on the grey menu. Our Y-Steps 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 (Y-Steps) 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 Y-Steps 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.
Y-Steps is 4 km (2 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.
