The Lowdown
Alright, Rusty here, let’s have a look at the forecast for Hiliduha.
We’ve got a decent run of swell building over the next couple of days. The water is sitting at 86° – that’s about 1° warmer than usual for this time of year, so noticeably balmy, but nothing too crazy.
The first real chance to paddle out comes Saturday the 29th. The afternoon at Hiliduha sees a 4ft SSW swell with a 14-second period, and a light breeze from the south. The combined energy is moderate at 717. It’s a bit average, though – the report calls it marginal, so don’t expect it to be firing.
Sunday the 30th morning is where it starts to get interesting. The swell drops to 3ft but it’s coming from the SW with a cracking 21-second period – that’s proper groundswell. The wind is glassy from the ESE at 3 mph, so it’ll be clean. Combined energy is strong at 963. This is a standout window for the more experienced crew, as this long-period SW groundswell will really suit the reef setup at Hiliduha. The only caveat is that long period stuff can be a little too straight-breaking at some spots, but on a reef, it’ll line up nicely.
The swell really builds through Monday and Tuesday, hitting 7ft on Tuesday morning (1st September) with a 17-second period and combined energy up at 2848 – that’s strong. But the wind is cross-onshore, so it’s not ideal. The real standout for the bigger stuff comes Tuesday afternoon: 7ft, 16-second period, glassy wind from the south at 3 mph, and an “excellent for experienced surfers” call. That’s the pick of the first week. At over 8ft, it’s expert territory, but 7ft is still a solid, powerful wave for advanced surfers. The energy is huge at 2344.
Wednesday morning (2nd September) holds similar quality – 6ft, SW, 16 seconds, glassy. Another excellent session for the experienced.
After that, the swell slowly fades through the rest of the first week and into the second, but it stays clean. Thursday the 3rd and Friday the 4th offer 4ft to 4ft SW swells, with 13-15 second periods and glassy winds. The energy drops to the 500-800 range, but still clean and fun. This is a good run for intermediate surfers on a longboard or a fish.
The second week has some promising windows. Saturday the 6th morning sees a 4ft SSW swell, 16 seconds, glassy calm – combined energy 855. Then Monday the 8th morning is worth a look: 4ft SSW, 15 seconds, offshore wind from the NNW at 3 mph. Clean and lined up.
The real sneaky standout in the second week is Wednesday the 10th morning: 4ft SW, 15 seconds, glassy calm from the NNE, with combined energy of 911. That’s a solid, clean, user-friendly swell for a morning session.
By Saturday the 13th, we’ve got a 5ft SW swell in the afternoon, 15 seconds, glassy, and combined energy at 1006 – that’s moderate energy but clean conditions. Sunday the 14th morning holds 5ft SW, 14 seconds, glassy, with energy at 1035. Another good one for the experienced surfers.
Overall, the best windows are: Sunday morning the 30th for the long-period groundswell, and Tuesday afternoon the 1st of September for the bigger, powerful swell with glassy conditions. Later in the second week, Wednesday the 10th morning is a solid, clean option.
Keep an eye on the crowds – Hiliduha can get them sometimes, so on the standout days, you might not have it to yourself.
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.
