The Lowdown
Right then, let’s cast an eye over the next couple of weeks for Y-Steps. To be straight with you, it’s looking pretty grim for a paddle. The whole 16-day run is a tough one. We’ve got a big, empty gap right at the start with barely a ripple worth mentioning until the end of the first week, and even then things don’t really get going. It’s all poor surf conditions, one after the other, which is a real shame.
So, Friday the 31st of July, we wake up to a tiny 0.7 ft cross-off wind swell out of the west. Clean enough looking, but just no power – the combined energy is only 4 (weak). That’s a write-off. Saturday and Sunday are even smaller, with gusts picking up, making it messy. Monday the 3rd of August goes onshore with a stiff breeze from the WSW, and the surf stays small and ugly. That pattern of light onshores holds through Tuesday and Wednesday, keeping everything flat and featureless.
We finally see a pulse of energy roll in on Thursday the 6th of August. The morning shows a clean 3 ft west swell, period a short 4 seconds, but its a start. By afternoon the wind drops to glassy calm, and the swell settles at a clean 3 ft from the WSW. The wave energy in the afternoon is moderate at 34. It’s the first time the ocean looks like it has any shape, but it’s still only for the most dedicated. There’s a tease on the 8th of August with a 4 ft north-west swell picking up on the Saturday morning, but that 19 mph cross-off wind will shred it, making it a test of patience.
The real event, and I mean the *only* standout in this entire outlook, happens on Monday the 10th of August. We see a proper pulse of strong, very high energy slam into the coast. The morning brings a solid 12 ft swell from the west-south-west, with a short period of 8 seconds. The combined energy is a massive 1482 (strong), which is a lot of water moving. This is not for beginners – that’s big, powerful stuff. The problem? The wind is howling from the west at 22 mph, putting it cross-onshore and creating lumpy, messy conditions. For paddle surfing, it’s going to be a battle, and the quality will be poor. Honestly, with that much wind and that big a swell at a beach setup, this looks far more interesting for the kite crew than anyone on a longboard.
After Monday, things drop off fast. The rest of the week into the 15th of August is back to tiny, weak swell and mostly onshore or light winds. A few clean moments but nothing with any grunt.
So, to sum it up: it’s a long, flat run with only one big, messy day on the 10th of August that’s really only for the experts or the kitesurfers. There is no good, clean surf on offer for the rest of the period. Hold tight, the forecasts can change.

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.
