The Lowdown
Alright, Rusty here again. Let’s break it down for the imperial crew.
Ekas-Inside is a sheltered reef, and the water temp is 79°, which is about average for the season. No weird anomalies.
The action starts on Wednesday afternoon, August 26th, but it’s a bit of a warm-up. Swell is 5ft from the SW with a 14-second period, energy is moderate at 972. The wind is a cross-off SE breeze at 15 mph, so the surf is clean but marginal. Thursday morning, August 27th, is better. Swell drops to 4ft but the period stretches to 16 seconds, energy is 1199, and the wind is light at 6 mph. Clean conditions for a longboard.
The big one is Friday morning, August 28th. Swell hits 8ft from the SSW with a 17-second period, and energy is pumping at 4103 – that’s strong. The wind is a gentle cross-off at 9 mph, so it’s glassy. This is excellent surf for experienced surfers only. The reef will be handling that long-period groundswell perfectly.
Saturday morning, August 29th, still has good energy at 7ft and 15 seconds, but the wind is a bit stronger. The first week stays consistent, with energy in the moderate to strong range. The second week sees a drop, with September 4th and 5th having smaller swell around 4ft to 6ft. But there’s a pulse on September 9th and 10th, with 7ft to 7ft swell and energy climbing back over 2000.
Your standout is Friday morning, August 28th. The rest is a solid run of clean, consistent surf, but that Friday is the one to plan for.
Rusty.

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