The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on offer for the next couple of weeks.

We’ve got a solid run of south-west groundswell heading our way, and it’s looking like a week of proper waves for the experienced crew. The water is sitting at about 80°, which is pretty much average for this time of year, so no surprises there.

The surf kicks off Monday afternoon, 17th August, with a clean 5 ft SSW swell – period a touch short at 14 seconds, but the energy is moderate (890). The SE wind is cross-off, so it’s rideable but not the pick of the week.

Tuesday 18th August is where things start to get interesting. The morning session sees a 4 ft SSW swell, but the period jumps to 16 seconds and the energy surges to 2053. That’s a proper groundswell, and with a gentle ESE cross-off, it’s clean and lined up. This is a standout morning for those who like a bit of power.

The real gem, though, is Wednesday 19th August. The morning brings a 8 ft SW swell with a 18-second period, pumping out 3724 in energy. The wind is offshore from the east at 9 mph, so it’s glassy and clean. This is the best on offer – a proper session for the experienced surfer. The afternoon holds similar size at 8 ft, but the wind shifts cross-off, so the morning is the clear winner.

Thursday 20th August keeps the pulse going with 8 ft SW swell and 16-second periods in the morning, energy at 4148. The wind is light cross-off, so it’s still clean and powerful. Another excellent morning for the confident surfer.

From Friday 21st through to the end of the month, we’ve got a solid, consistent run of 6 ft to 7 ft SSW and SW swell, with periods between 15 and 17 seconds. The cross-off winds are a constant feature, but the wind picks up a bit, so conditions are good but not as pristine as the Wednesday morning peak. The energy stays in the moderate to strong range, so plenty of push.

Now, for the first week of September, there’s a significant uptick in power. On Monday 31st August, the morning shows a 5 ft SW swell but with a very long 21-second period, energy at 3856. That’s a deep ocean groundswell. The afternoon jumps to 7 ft with a 20-second period and 4421 energy. However, the wind is a fresh 22 mph, cross-off, so it’s going to be a bumpy, energy-filled challenge. Tuesday 1st September sees 8 ft SW swell, 18-second periods, and energy at 4546, but again with fresh 19 mph cross-off winds. This is big, powerful, and only for the experts. The quality is a bit blown out, but the raw power is there.

The standout is Wednesday 19th August morning. That 8 ft, 18-second SW swell with offshore wind is the clear winner. Tuesday 18th August morning is also a top pick for the cleaner, slightly smaller conditions.

If you’re not an expert, the 4 ft to 6 ft days are your window, but keep an eye on the period – those long-period swells can be tricky at a sheltered reef like Ekas-Inside, but when the direction is right, they hold up beautifully.

Alright, that’s the wrap. Get out there and get wet.

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.
