The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Water temp is 80°, right where it should be for this time of year – no drama there. We’ve got a decent run of surf coming, but the first week is a bit of a mixed bag. The real highlight is the second Tuesday, September 8th. That morning you’re looking at a 8ft SW groundswell with a very long 19-second period, and the afternoon pumps it up to 10ft from the SSW with 18 seconds. The energy is massive – hitting 4047 in the morning and 4841 in the afternoon. That’s serious power. Wind is cross-off from the SSE at 16 mph, keeping the faces clean. This is a reef break, so that long-period swell will line up beautifully. It’s a beginner-friendly wave, but at over 8ft, this is for the experienced crew only. That Tuesday afternoon is the one.
Before that, from the 1st to the 7th, we’ve got a steady 6ft to 7ft SW/SSW swell, but it’s all marked as marginal due to tide or quality. Winds are cross-off, not ideal, with energy in the moderate to strong range (1277 to 2476). It’s surfable but nothing special. Crowds are possible here – it says ‘sometimes’, so expect company.
After the 8th, the swell backs off a touch. The 9th and 10th keep a 7ft to 8ft pulse with 16-17 second periods, energy still strong (2261 to 3119), but the wind stays cross-off. From the 12th onward, we’re into smaller stuff – 4ft to 5ft, periods dropping to 14-15 seconds, energy falling below 1500. The 13th afternoon has a sneaky 4ft but a 17-second period, which could give some clean little runners. The last few days, the 15th and 16th, see a lift back to 6ft-7ft SSW swell with 15-second periods and energy around 1460 to 1857. Winds ease to a light breeze on the 16th morning – that’s promising. Still, nothing beats that Tuesday the 8th.
It’s a slow burn with one absolute cracker. That Tuesday the 8th is the one to mark on the calendar.

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