The Lowdown
G'day, I'm Rusty, and I'm looking at the surf outlook for Hiliduha. This is a classic reef break that's exposed to the southwest swell, and it's a spot for the experienced crew – it's rated advanced and fairly consistent.
The water temps are sitting right on 86°, which is about average for this time of year, so no surprises there.
The next few days are a bit of a write-off, to be honest. The swell is there, but the conditions are just messy. From Thursday the 20th through to Sunday the 23rd, we're looking at a solid 6 ft to 8 ft southwest swell, but the wind is all over the place – cross-on, light breezes, and a bit of a bumpy surface. The energy is in the water, but it's not going to be clean. The reports are calling it marginal, and I'd have to agree.
Then there's a bit of a lull from Monday the 24th morning through to Wednesday the 26th morning. The swell drops to 4 ft to 6 ft, but the wind goes glassy on Monday the 24th morning, which is a highlight. The swell period is a very long 17 seconds, and the energy is moderate (1748). That's going to be clean, but it's a big tide-swell combo for a deep reef, and it's only for experienced surfers. The afternoon of the 24th is back to marginal.
We get another drop in swell from Wednesday the 26th afternoon through to Sunday the 30th, with 3 ft to 5 ft waves. The wind is often onshore or light, and the energy is low (below 1000). The periods are short to medium (13-15 seconds), so not much to get excited about. There's a glassy moment on Wednesday the 26th morning, but the swell is small at 4 ft.
Now, the real standout arrives on Monday the 31st of August. The afternoon glass-off with a 5 ft southwest swell and a very long period of 19 seconds is a proper gem. The energy is strong (2466), and the conditions are glassy. That's going to be a clean, powerful wave at Hiliduha. The morning of the 31st is a bit cross-on, but the afternoon makes up for it.
And then, the first few days of September are firing. Tuesday the 1st of September is a dream: glassy conditions all day, with a 7 ft to 7 ft southwest swell and a period of 17-18 seconds. The energy is very strong (2732 to 2994). That's classic Hiliduha – a proper groundswell on a reef with clean conditions. It's going to be big and powerful, so only for the advanced crew. Wednesday the 2nd of September is also excellent, with glassy mornings and a clean cross-off in the afternoon, with a 6 ft to 7 ft southwest swell. Thursday the 3rd of September has offshore winds and clean 6 ft swell.
The best of the best is Tuesday the 1st of September. The swell is big, the wind is glassy, and the energy is pumping. That's your day.

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.
