The Lowdown
Alright crew, Rusty here, checking in on Y-Steps. I've got to level with you – the outlook for the next 16 days is a total bust. We're looking at a long stretch with no real surf to speak of. The wave energy is nearly non-existent, and when there is a small bump, the conditions aren't there to back it up. This kind of dry spell isn't uncommon around here, but it's still a bummer.
The forecast kicks off on Monday, September 14th with a weak 2ft west swell at a short 5-second period. The combined energy is a measly 18. The morning has a WSW wind blowing at 12 mph, making it onshore and choppy. The afternoon doesn't improve. Tuesday and Wednesday are more of the same: tiny swells, crummy winds, and energy readings barely cracking 28. By Thursday, September 17th, the swell drops to a tiny 0.3ft. While Thursday morning is glassy, there's no height to ride. This flat pattern, with energy readings of 1, 2, or 3, stretches all the way through the end of the month.
There's a faint pulse on Saturday, September 19th afternoon with a 4ft northwest swell and a short 5-second period. The energy jumps to 66 – the highest we'll see – but with a north wind at 12 mph, it's cross-offshore and still messy. The period is too short and the direction is off for Y-Steps, which really wants a southwest swell. It's not worth chasing.
After that, it's back to the flat spell. The final days of September and into October show nothing but 0.3ft to 0.7ft swells. Even a long-period 19-second groundswell on Sunday, September 27th morning is only 0.3ft – all period, no power.
There's no standout session here. Nothing worth highlighting. The water temperature on Monday morning is about 59°F, which is just over a degree warmer than average, so nothing crazy there. On some of those windier, choppier days, this spot is probably better suited for a kite than a paddle board. Leave the wetsuit in the closet and keep an eye on the long-range models.
Hang in there.
Rusty.

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.
