The Lowdown
G'day, I'm Rusty. Let me be straight with you: the next couple of weeks around Seper are looking pretty grim for a proper paddle. We've got a long stretch of poor surf conditions, so don't rush to wax up just yet.
The pattern is mostly small, weak swell with onshore or cross-shore winds ruining whatever waves show up. The combined swell energy is moderate at best, topping out around 505 on September 19th, but even then the wind is a problem. For the first week, from Monday the 14th right through to the weekend of the 20th, it's all cross-on or onshore wind, making for choppy, lumpy, or just plain messy surf. There's a brief moment on Tuesday morning the 15th where the wind goes cross-off and it cleans up, but the swell is only 3ft from the ESE with a short period of 8 seconds – not much power behind it, and combined energy of 153 is weak to moderate.
The water temperature is sitting at 80°F, which is a touch warmer than normal for this time of year – the anomaly is 2°F, so it's a bit of a nice surprise if you get in, but the surf itself is the letdown.
Now, a few days in the second week might get your hopes up but don't get too excited. On September 23rd, Wednesday afternoon, we see a jump in period to 12 seconds from the ESE with a combined energy of 532, but it's still cross-on and the swell height is only 5ft. That's a long period groundswell, so it'll have more energy but also longer gaps between sets. It's a reef break, so that long period might actually wrap in okay, but the onshore wind will chop it up. September 24th, Thursday morning, also has some potential with 4ft from the ESE and an 11-second period, combined energy of 417, and the wind is cross-shore – still not perfect, but a little better. Honestly, nothing here is a standout.
Forget about any real quality sessions. The best you could do is Tuesday morning the 15th for a quick, clean, but small wave, or maybe Thursday morning the 24th for a slightly punchier but still messy option. There's nothing over 5ft until September 18th when it hits 6ft, but that's with a 6-second period and onshore rain – terrible combo. After September 27th, the swell drops right off to nothing.
This is a long dry spell, nearly the whole 16 days. If you're keen, wait for a cleaner window, but honestly, the forecast can change. For now, it's a quiet period at Seper.
Rusty.

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