The Lowdown
G'day, Rusty here, and I'm looking at the forecast for Hiliduha. It's a reef break that's fairly consistent and exposed to the swell, with the best direction coming from the SW. It's an advanced wave, so keep that in mind.
The water temp is about average for this time of year, nothing to write home about. We're in for a bit of a slow start, and honestly, the first week isn't looking too special. The surf is on the small side, with a lot of cross-onshore wind making things a bit choppy. The energy is moderate to strong, with readings around 862 to 1551 units, but the quality just isn't there. You'll be looking at marginal surf at best.
Now, let's get into the nitty-gritty. The standout action is definitely going to be from Wednesday 19 August onwards. The swell starts to build, and by Wednesday afternoon we're looking at a solid 8ft SW swell with a long period of 18 seconds. That's a groundswell, and it's packing a punch with a combined energy of 4422—that's some serious juice. The wind is light from the SSW, which is onshore, but the size and power will have you thinking. This is one for the experienced crew only, as it's pushing into expert territory.
Thursday 20 August keeps the size up at 8ft in the morning, still with a 16-second period. The energy is still massive at 3352. The wind is onshore, but it's light. The afternoon sees a slight drop to 8ft, but still powerful.
The next true standout is a bit further out, but it's worth the wait. Friday 28 August is looking glassy. The morning has a 4ft SW swell, but with a very long period of 19 seconds. That's a groundswell that will wrap around nicely. The energy is moderate at 1125, but the glassy conditions will make it clean. The afternoon is even better, with a 5ft SW swell, 18-second period, and glassy wind. The combined energy jumps to 2064, and the conditions are described as excellent for experienced surfers. This is the pick of the window.
Saturday 29 August is also a stunner. The morning has a 7ft SW swell, 18-second period, and glassy wind. The energy is strong at 2662. This is a big, clean swell, but it's for experts. The afternoon holds similar with a 7ft, 17-second period, and glassy conditions. This is a ripper of a weekend.
The following week sees a bit of a drop-off, but it's still surfable. The best of the rest is Wednesday 26 August, with a glassy afternoon and a 4ft SW swell, 14-second period, and low energy of 690, but those clean conditions will be fun on a smaller board.
In summary, the first few days are a write-off, but from the 19th onwards, the swell builds. The real gold is on Friday 28 August and Saturday 29 August with clean, glassy conditions and a powerful SW groundswell. Get on it, but only if you've got the skills.
Stay stoked, 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.
