The Lowdown
Right then, let’s have a look at what’s coming down the line for Easky Left. This is a proper advanced reef break, exposed and hungry for that northwest groundswell, and it’s going to see some serious water over the next couple of weeks. The water temp is about average for this time of year, nothing unusual there.
First things first – the start of the forecast is a write-off. Wednesday the 16th is a mess with a strong cross-shore wind and lumpy, choppy conditions. The swell energy is high, reading 1256 (moderate), but the quality just isn’t there for us. Thursday the 17th is even worse – a big, raw, windy mess with swell energy up at 5949 in the morning and a monstrous 12073 in the afternoon. That’s strong to very strong energy, but with 25 mph cross-winds and 20 ft of swell, this is strictly for experts only, and even then, it’s ugly. Honestly, it looks more interesting for kite surfing than paddle surfing.
We finally get a window on Friday the 18th. The morning sees a light offshore breeze from the SSW, cleaning up a solid 13 ft swell from the WNW. The period is 13 seconds, a proper groundswell, and the energy is still strong at 5645. This is one of the standouts. It’s still big, over 8 ft, so only for experienced crew, but the offshore wind will make it look a lot better than the previous days.
Saturday the 19th steps back a bit with cross-shore winds and lumpy conditions, so we’ll skip that. Then, we get another gem on Sunday the 20th. Morning has a gentle cross-off breeze, and by the afternoon it turns into a clean, gentle offshore from the SSW. Swell drops to a still-chunky 10 ft from the WNW, with 2410 of moderate energy. The conditions are described as excellent for experienced surfers, and that offshore wind will have those reef walls standing up nicely. This is the best of the early run.
Monday the 21st keeps the quality high with a gentle offshore wind and clean surf, dropping to a more manageable 6 ft. The energy is down to 901 (moderate), but it’s still very good. Then Tuesday the 22nd is a real beauty – a glassy morning with zero wind and a 5 ft swell, but the period jumps to a very long 17 seconds. That’s a serious groundswell, and combined with the glass, it’ll be perfection on the reef. The energy is 1874, which is moderate but punchy. This is a standout session for the experienced surfer, though with crowds listed as ‘often’, expect a few locals out.
The middle of the week from Wednesday 23rd to Thursday 24th starts to fade in size and quality, with smaller swells and more cross-off breezes. Nothing to get too excited about.
Moving into the second week, we get a bright spot on Friday the 25th of September. Clean, light offshore winds from the SSE and a 8 ft swell from the NW with 1327 energy. It’s clean, offshore, and excellent for experienced surfers. A solid call.
The 27th of September (Sunday) has another promising moment – a morning glass-off with a 8 ft swell from the west at a long 13 seconds, and light offshore winds. The energy is 1945 (moderate). The afternoon turns onshore and choppy, so hit it early.
After that, the window closes. Monday the 28th and Tuesday the 29th see onshore winds and dropping swell, and by the end of the month and into October 1st, it’s all small, weak, and ordinary.
So, for the best of the lot: Sunday the 20th afternoon with that gentle offshore and clean 10 ft groundswell, and Tuesday the 22nd morning for the incredible glass and that 17-second groundswell. Get on it if you can handle the reef.

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

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 Easky Left 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.
