The Lowdown
Alright, Rusty here. Let's get into it.
We've got a single spot on the radar this period, Hiliduha, a reef break that only comes alive for the advanced crew. It's a fairly consistent spot, and even though it can get busy sometimes, the quality on offer over the next couple of weeks makes it worth jostling for a spot.
The water temp is about average for this time of year, nothing out of the ordinary.
Things kick off on Wednesday the 2nd, but it's a bit of a write-off. We've got a solid 6ft SW groundswell at 16 seconds, with heaps of energy (1647), but that ESE wind is putting a chop on it and the conditions are marginal. The afternoon is much the same, just a touch smaller at 5ft.
Thursday the 3rd is a bit of a tease. The morning brings cleaner lines with a light NNW cross-off wind, and the swell drops slightly to 4ft (850 energy). It's a step in the right direction, but nothing to lose your mind over.
Now, Friday the 4th is where we start to see some real promise. Early morning, the wind goes completely glassy with a NNE breeze, and we've got a clean 4ft SW swell. The afternoon stays glassy with a light W wind. This is a nice, clean, manageable window.
Saturday the 5th and Sunday the 6th are largely forgettable. The wind swings onshore, the swell gets messy, and the energy drops. It's not worth paddling out for unless you're desperate for a paddle.
Monday the 7th is another one to look at. Glassy conditions early with a SE breeze and a clean 4ft SSW swell (799 energy). It's a solid morning session.
Then we hit the real standout. Tuesday the 8th of September. The morning brings a 3ft SSW groundswell with a very long 18-second period. The combined energy is strong (1068) and with a light NW cross-off wind, the conditions are clean and perfect for experienced surfers. This is a day for the initiated. The long period will make it wall up nicely on this reef.
The following few days keep the quality high. Wednesday the 9th through Friday the 11th all show glassy mornings with 5ft to 5ft SSW/SW swell and period around 15-16 seconds. Energy levels stay well into four digits (1097 to 1268). Excellent conditions for those who can handle it.
As we get into the second week, the size starts to pick up. Saturday the 12th of September is a big one. The Saturday afternoon session shows a 7ft SW swell with a 19-second period. The combined energy is massive (3563) and a cross-off wind keeps it clean. This is expert territory, no question. Only the brave need apply.
Sunday the 13th keeps that size, with a glassy 7ft SW swell in the morning, and the afternoon stays glassy with a light WSW wind. Still solid, clean, and for the experienced.
The rest of the second week (14th to the 17th) settles back into a very consistent rhythm. Morning glass-offs, clean conditions, and a steady 5ft to 6ft SW groundswell. Energy is consistently high, and the period stays in the sweet spot. This is a long run of quality for Hiliduha.
If you had to pick the absolute best on offer, it’s the Tuesday the 8th for the perfect conditions and that long-period swell, and the Saturday the 12th for the raw power. Both are fantastic, but for different reasons.
Rusty.

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