The Lowdown
Alright, this is Rusty checkin' in with a look at what's on the menu for Hiliduha. We've got a solid run of groundswell on the cards, but this spot ain't for the faint of heart.
The pattern shaping up is a classic run of long-period SSW energy, and for a reef break like Hiliduha, that's a recipe for some serious, powerful lines. The water temp is sitting about average for this time of year, so you're not gonna need the thickest rubber.
The action kicks off Friday, August 7th. We're looking at a 6ft SSW groundswell with a 15-second period, and with a light northerly breeze in the morning going glassy by the afternoon, conditions will be clean. The combined energy is already strong at 2439, and by the arvo it's pumping up to 3170 with a 7ft, 18-second SSW swell and glassy conditions. This is top-tier, heavy reef surf for experienced surfers only.
Saturday the 8th keeps the good times rolling with more 7ft SSW groundswell and glassy conditions all day. The energy is still massive at 2578. Sunday morning the 9th is looking glassy and calm with a 6ft SSW swell, but by the afternoon a southerly breeze picks up onshore, so get your sessions in early.
Monday the 10th offers a bit of a contrast. The morning is a clean 6ft SSW swell, but check out the afternoon: a 4ft wave with a 22-second period. That's incredibly long-period groundswell, and while it’ll have plenty of energy (2100), it might be a bit too straight for this reef and better suited for a point break. Still, worth a look if you're an expert.
We hit a bit of a rough patch from Tuesday the 11th through Wednesday the 12th with cross-onshore winds messing with the surface quality. The swell is still there, but it's not going to be pretty.
The standout window really opens up again on Friday, August 14th. The morning shows an 8ft SSW groundswell with a cross-offshore breeze from the northeast, making for a clean, pitching wave. The energy is huge at 3166. This is a serious session for experts.
Saturday the 15th and Sunday the 16th hold some good, clean morning windows, but the real highlight, the one you need to circle on the calendar, is Wednesday, August 19th. We're talking an 8ft SSW groundswell in the morning going to a solid 10ft SW groundswell in the afternoon, both with glassy conditions. The energy is off the charts at 5828. This is an exceptional day for expert surfers only. Over 8ft and this heavy a reef, it's a full-on charging mission.
After that, the 20th and 21st keep the energy high with more 8ft SSW swell and plenty of glassy windows, but the winds get a bit tricky on the afternoons. Still, plenty of power on offer.
Overall, this is a fantastic stretch for the advanced crew. The standout is Wednesday the 19th – that's the one to aim for. Get it while it's glassy.

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.
