The Lowdown
G’day, Rusty here.
Alright, straight up – the next couple of weeks are a tough watch at Emery’s Left (Big Island). We’ve got a decent reef setup that’s exposed to the west, but the conditions are just not playing ball for a proper paddle session. There’s a long stretch of poor surf quality ahead, so let’s break it down.
Starting Monday, September 14th, we’ve got a modest 4ft swell rolling in from the west, with a period of 8 seconds, so it’s short-period windswell. The combined energy is moderate at 405, but the problem is the wind – a steady 9 mph cross-onshore from the SSW is making things choppy. No crowd info on this one, but given the poor surf conditions, it won’t be busy. It’s not a beginner day either; the swell isn’t huge, but the chop kills it. The water temp anomaly data isn’t supplied here, so I can’t give you the usual rundown on that.
Tuesday the 15th sees the swell drop right off to 2ft in the morning, with a very long 16-second period from the southwest. The energy is still moderate at 281, but again, cross-onshore wind keeps it ugly. By the afternoon it’s down to 1ft with a 20-second period – that’s an incredibly long groundswell, but with only 348 combined energy, it’s too weak to do much on this exposed reef. The wind is light cross-onshore, but the waves are just not there.
The rest of the week, from Wednesday the 16th through to Sunday the 20th, is a dead zone. Swell heights hover between 2ft and 3ft, all from the southwest. The periods are long (15 to 19 seconds), which would usually be exciting for a reef, but the cross-onshore or even onshore winds (from the west and WNW) keep things messy. The morning sessions on Wednesday the 16th, Friday the 18th, and Sunday the 20th have a “marginal” tag, but with scores that low, it’s barely worth suiting up. The wind is light, but the surf quality is just not there. The combined energy ranges from 285 to 565, all moderate, but wasted.
Now, the second week picks up a tiny bit, but it’s still grim. Monday, September 21st, gives us a glimmer – 3ft from the southwest at 17 seconds, with 555 combined energy in the morning. The wind is light onshore. It’s marginal, but you might find a dribbler if you’re desperate. Tuesday the 22nd through to Sunday the 27th, it’s back to poor, with swell dropping to 2ft later in the week. The winds turn more cross-onshore from the northwest, picking up to 12 mph on the 24th and 27th, making it choppy and ugly. Not a single standout.
The very last day, Tuesday, September 29th, has a 2ft, 18-second period swell from the southwest, with 451 combined energy, but it’s still cross-onshore and poor. Honestly, if you’re looking for a wave this fortnight, you’re better off checking the kite setup – the onshore winds and small, weak swell here would suit a kite way more than a paddleboard.
To sum it up: there’s no true standout. The best of a bad lot is probably the morning of Monday the 21st, but that’s a long shot. The whole 16-day window is a write-off. Expect a lot of flat, choppy days with no real quality.
Rusty.

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