The Lowdown
G’day, Rusty here. Looks like we’ve got a solid run of surf lining up at Ekas-Inside, but with a catch – the whole 16-day stretch is plagued by cross-off winds, so conditions won’t ever be truly glassy. Still, there’s plenty of swell on offer, and you can surf every day if you’re keen.
The first real surf kicks off this Saturday, 5 September, with a 7ft SSW swell rolling in. It’s a clean wave but the SSE wind’s blowing cross-off at 12 mph, so it’s a bit lumpy. The combined energy is already strong at (1458). This isn’t a standout day – just a warm-up.
Sunday the 6th and Monday the 7th keep the same pattern: 7ft and 7ft SSW swells, still cross-off, still moderate breeze. The energy climbs to (2136) on Sunday morning and stays in the strong zone. Nothing to write home about, but you’ll get waves.
Things start to shift Tuesday the 8th. Swell drops to 5ft in the morning but the period stretches to 19 seconds – proper groundswell. Combined energy jumps to (2754). By the afternoon, it’s 6ft at 18 seconds and energy hits (3561). This is a nicer quality swell, but those damned cross-off winds keep it from being perfect.
Wednesday the 9th sees swell size pushing 8ft, still from the SSW, period around 16 seconds. Energy is very strong at (3336). At this size it’s getting a bit much for beginners – maybe leave the foamie at home. The wind stays cross-off from the SSE or S.
Thursday the 10th and Friday the 11th both hover around 6ft to 7ft, solid SSW swells, energy in the (2000-2400) range. Still cross-off. The consistency is fairly consistent, so you won’t be waiting long.
Saturday the 12th offers a slight reprieve – wind drops to 9 mph from the SE, still cross-off, but the afternoon sees a 5ft SW swell with a hopeful note: “expect very good surf conditions.” It’s the first time the forecast gets excited. Energy sits at (1566) – moderate to strong. This is a potential highlight if the wind behaves.
Sunday the 13th is another strong day: 6ft in the morning, 8ft in the afternoon, both SW and 18 seconds. Energy rockets to (2944) and (3483). Still cross-off. That longer period groundswell will wrap in nicely on this reef break, so the waves should have some punch and shape.
Monday the 14th and Tuesday the 15th stay in the 7ft to 7ft range, SW swell. Wind picks up to 16-19 mph on Tuesday afternoon, which is a bit of a blowout. Energy drops off gradually.
A bit of a lull hits mid-week around the 16th and 17th, with swell dropping to 5ft-6ft, periods shortening to 14 seconds. Energy sits in the (1200-1500) range – moderate. Still clean, but nothing special.
The real standout pops up on Friday the 18th afternoon. Swell bumps to 7ft from the SSW, 16-second period, and the wind eases to 9 mph from the SSE. Energy hits (2431). The forecast calls this “excellent surf conditions for experienced surfers.” At 7ft it’s solid, and with that gentle breeze the surface should be clean. This is your best bet for the whole run – get on it.
Saturday the 19th has 8ft SW swell all day, energy over (3000). Still cross-off, but at that size and from the optimum direction, Ekas-Inside will be pumping.
Looking further out to Sunday the 20th (that’s two weeks away), the model is showing a 10ft SW swell with a very long 21-second period. Combined energy is massive at (6923). That’s heavy groundswell – powerful, long lines, but with those long gaps. It’s going to be thick and likely too big for anyone but the most experienced. Wind is still cross-off from the SE at 16 mph. Promising but very uncertain this far out.
Water temp is running about average for this time of year, no anomaly flagged – so you’re looking at your usual tropical warmth for this spot.
Crowds are noted as “sometimes” busy at Ekas-Inside, but given the reef setup and consistent swell, it’s not usually a zoo. The break itself is a sheltered reef, beginner-friendly at smaller sizes, and the SSW optimum direction lines up perfectly with what’s forecast most days.
No kite-surfing call here – the cross-off wind and reef setup keep it firmly a paddle-friendly wave.
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.
