The Lowdown
Alright folks, Rusty here. We’ve got a solid run of swell heading our way to Hiliduha over the next couple of weeks. This is a proper reef break, so it’s one for the advanced crew only. The water temp is about average for this time of year, so nothing too wild there.
The action kicks off Monday the 14th of September. We’re looking at a strong SW groundswell pushing through, with a hefty 1485 combined energy reading. Swell heights are sitting around 6ft with a long 15-second period, which is going to produce some proper shaped waves. The wind is a light cross-off from the NNE, keeping things clean. Monday afternoon sees the period stretch to 16 seconds and the energy jumps to 1794, with a light WNW breeze. This is excellent, powerful surf, but it’s only for those with the experience to handle it.
Tuesday the 15th is a standout morning. We’ve got glassy conditions with an ENE breeze, that same 6ft SW swell, and a 15-second period. The energy is still strong at 1432. It doesn’t get much cleaner than this for a powerful reef break. Tuesday afternoon the wind swings to a light cross-on from the SW, so it’s not as good.
Wednesday the 16th is a bit of a mixed bag. The morning is a write-off with a cross-on SSE wind and the swell dropping to 5ft. But the afternoon turns glassy again, with a 5ft SW swell at 14 seconds. The energy dips a bit to 1079, but those clean, glassy conditions will still offer some fun, albeit smaller waves.
Thursday and Friday see a drop in size and consistency, with the wind being a bit of a pest. Saturday the 19th is a complete loss with strong onshore winds and poor conditions.
Then we get the real prize. Sunday the 20th of September. This is the one to circle. The morning is glassy with an easterly breeze, and the swell builds back to 6ft from the SW, with a 16-second period. The energy is a massive 1634. The afternoon is even better, still glassy with a 6ft SW swell and 1754 energy. This is going to be incredible. The reef will be handling all that power, and with no wind, it’s going to be a session to remember. Expect some crowds though, as this is a known spot.
The following week has more promising windows. Monday the 21st morning is glassy with a 6ft SSW swell. Tuesday the 22nd morning is glassy but much smaller at 3ft. The big news is Sunday the 27th of September. The morning is dead calm, glassy, with a 5ft SSW groundswell and a 15-second period, and a solid 1582 energy reading. Then Sunday afternoon the period jumps to a massive 20 seconds and the energy rockets to 2768, with a 5ft swell. The wind is a light cross-on, but with that kind of long-period groundswell, the waves will be powerful and well-shaped at this reef.
Finally, Monday the 28th of September has some size. The morning is a bit tricky with a cross-shore wind and 7ft SSW swell, but the afternoon turns glassy with a 7ft SSW swell and 2516 energy. This is big, powerful, and only for experts.
The best of the best is undoubtedly the 20th of September. Perfect conditions, solid swell, and glassy all day. The 27th also has a monster groundswell, but the wind is a little less ideal.

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.
