The Lowdown
Righto, I’m Rusty, and I’ve been staring at the charts for Hiliduha. This is a reef break and it’s exposed to the swell, with the best direction coming in from the SW. We’ve got a 16-day window ahead, and there’s actually a bit of a slow start followed by some real promise.
The water temp here is sitting about average for this time of year. Nothing wild, just what you’d expect.
We kick off on Wednesday the 12th and Thursday the 13th of August, but honestly, it’s a bit of a write-off. The wind is cross-on and onshore, the swell is there but the conditions are messy. You’re looking at a moderate combined wave energy, but it’s not clean enough to get excited about. A couple of days to sit out.
Then Friday the 14th morning, things start to turn. The wind goes glassy, and we’ve got a solid 6ft SSW groundswell rolling in with a long 16-second period. The combined energy is strong, and the conditions are marked as excellent for experienced surfers. This is a real standout. The long period is going to give those waves some serious shape and power, and with the glassy conditions, it’s going to be clean. Hiliduha is a reef, so that long-period swell will wrap in nicely. Keep in mind it’s a fairly consistent spot, but it’s advanced territory, so if you’re not confident, maybe give it a miss.
Saturday the 15th keeps the glassy theme going, both morning and afternoon. Swell drops a little to 5ft and 5ft from the S, with a period of 14 and 13 seconds, still good energy. Conditions are excellent for experienced surfers again. This is a solid run of clean surf.
Sunday the 16th morning, the wind is dead calm, glassy as it gets, but the swell drops to 3ft from the SW with a 15-second period. The energy is moderate. It’s good for a longboard or a fun shape, but won’t have the punch of the previous days. The afternoon gets a bit onshore and messy.
Monday the 17th is small again, 3ft SW swell, but the wind is glassy in the morning and cross-off in the afternoon, keeping it clean. The energy is lower, so think small but fun waves.
Then we hit a gap. Tuesday the 18th and Wednesday the 19th, the swell kicks up big time, but the wind goes cross-on and onshore, chopping it up. The combined energy is very strong, with Thursday the 20th still holding big 8ft SSW swell, but the wind is cross-on. This is big, powerful, and messy. For experienced surfers only, and even then, it’s not going to be pretty. The setup looks more interesting for kite surfing than paddle surfing.
Friday the 21st and Saturday the 22nd of August, the swell stays up around 7ft to 8ft from the SSW, but it’s still cross-on with light winds. The energy is strong, but the quality is marginal. Not the best.
Sunday the 23rd afternoon, we get another glassy window. The swell drops to 6ft from the SSW, period 14 seconds, and the combined energy is strong. Conditions are excellent for experienced surfers. This is another standout if you can wait it out.
The last few days, Monday the 24th to Thursday the 27th, the swell settles back to 4ft to 6ft, but the wind is onshore or cross-on for most of it, keeping it a bit average. Not much to write home about.
So, the best of the bunch is Friday the 14th morning through Saturday the 15th. Glassy, solid groundswell from the SSW, and that long period is going to make Hiliduha a proper reef wave. The Sunday the 23rd afternoon is also a good shout if you’re planning further out.
Stay stoked, and paddle hard.

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.
