The Lowdown
Hey, Rusty here. Let’s talk about the waves at Ekas-Outside over the next couple weeks.
Right off the bat, we’ve got a decent stretch of swell but the tide’s messin’ with the quality early on. Water temp is about normal for this time of year, nothing crazy.
The whole run is built on that consistent SW to SSW groundswell. The one you want to plan for is Friday, August 28 morning. Swell at 8ft from the SSW (moderate energy, 4273), light SSE cross-off wind—it’s clean, powerful stuff for experienced surfers only. That’s the standout.
The week before, from August 21 through the 26th, we’ve got 7ft to 8ft days, but that 15-25 km/h cross-off wind from the SE or SSE keeps things just okay. Nothing terrible, but the tide’s not helping. Energy ranges from around 1100 to 3400, so it’s pushing, just not perfect.
By Thursday August 27 morning, it drops to 3ft from the SW, period 16 seconds, with light wind, but it’s small. Then the big one on the 28th hits.
After that, Wednesday September 2 is another winner: 8ft from the SW, period 16 seconds, and the wind goes glassy offshore from the ESE at 10 km/h—beautiful. Energy is solid at 2754. Thursday September 3 morning is also good: 7ft from the SSW, with light offshore wind.
Into the second week, Friday September 4 is pumping. The afternoon sees 8ft from the SSW, period 19 seconds, with the combined energy hitting 7113. The morning is also 7ft with 20-second period and 4934 energy, plus light SE wind. Both mornings and afternoons are clean, but the 4th is the big power session for experienced crew.
Crowds at Ekas-Outside can happen—it’s a fairly consistent reef that likes the SSW direction. There’s a slow start with no real surf until the 21st, and the 27th is quiet, but once it fires, it fires.
Rusty.

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.
