The Lowdown
Alright, Rusty here again, switching to feet. Let's break it down.
We've got a solid run of swell ahead at Ekas-Inside, but don't get too excited just yet. The first few days are going to be big but a bit raw, and the best windows are for the crew who know what they're doing. The water temp is right on average for this time of year at 79°, so nothing unusual there.
The action kicks off Tuesday the 11th of August. We're looking at a solid 10ft SSW groundswell, and I mean *solid*. The combined energy is a massive 5075 (very strong wave energy), but this is a reef break and it's sheltered, so it'll handle it. The wind is a cross-off from the SE at 12 mph, keeping things clean. This is serious surf though—over 8ft, so this is only for experts. The period is a very long 17 seconds, which means long, powerful lines and long waits between sets. At a reef, that's a dream scenario for the experienced surfer.
Through Wednesday the 12th and Thursday the 13th, we ease back slightly to 7ft to 8ft, still from the SSW, with a long period (14 to 17 seconds). The wind stays cross-off from the SE at 12-15 mph, so the surface stays clean. The energy is still high (between 1933 and 3823). This is still a lot of power; beginners should sit this one out.
Friday the 14th through Sunday the 16th holds fairly steady. Swell hangs around the 7ft to 8ft mark, same SSW direction, long periods. Winds are lighter, especially Sunday morning at just 9 mph, which is a nice gentle breeze. The energy dips a little (down to 1950-2271), but it's still a meaty reef break wave.
Now, the standout. Look at Monday the 17th. It drops to 5ft, but the combined energy is down to 1099 (moderate wave energy). The wind goes a bit more east-southeast at 9 mph. It's cleaner, smaller, and less intimidating. This is where the door opens for more surfers. But the real gold is on Tuesday the 18th of August. The swell direction swings to the SW, still 5ft to 6ft, but the period jumps to 16 seconds, and the energy shoots back up to 2360 (moderate to strong). The morning looks excellent for experienced surfers, with a gentle SE breeze. This is a fantastic window—clean, powerful, but not the terrifying size of the week prior.
Moving into the second week, things look promising but less certain. Wednesday the 19th through Saturday the 22nd bring a consistent 7ft to 8ft SW swell, still with long periods (16-17 seconds) and high energy (2615-3469). Winds are mostly cross-off from the SE at 12-15 mph, keeping things tidy. The best-looking morning in this stretch is Friday the 21st of August, where the wind turns offshore from the ESE at just 9 mph. This is a rare, clean, offshore window for an 8ft SW swell. It's described as "excellent for experienced surfers," and I have to agree. That's your second standout: a clean, powerful Friday morning.
From Sunday the 23rd through Monday the 24th, the swell backs off to 5ft to 6ft from the SSW, with shorter periods (13-14 seconds) and lower energy (1087-1419). The wind stays cross-off. This is the lull in the action.
Then, Tuesday the 25th of August, we see another bump. A 7ft to 8ft SSW swell rolls in with a very long 18-second period and massive energy of 3720. That's the biggest energy of the whole run. But the wind is cross-off at 15 mph, and the afternoon picks up even more strength. This is for the hardcore crew only.
So, to sum it up: the best on offer are Tuesday the 18th of August morning for a clean, powerful, manageable SW swell, and Friday the 21st of August morning for that rare offshore window on a solid SW swell. The rest of the run is consistent but testy. The crowds at Ekas-Inside can be an issue *sometimes*, so get on it early.
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.
