The Lowdown
Alright folks, Rusty here. Let’s get into it for this little window we’ve got.
We’re looking at a solid stretch at Hiliduha (reef). The water is sitting at a warm 86°F, which is about average for the time of year, nothing wild there.
The first few days are a bit of a write-off. Friday the 24th is a no-go – cross-onshore wind and marginal surf. Not worth paddling out.
Things start to turn around on Saturday, July 25th. That morning, the wind goes glassy, and we’ve got a 5ft south swell, period 10 seconds. The energy is moderate (693). It’s not huge, but it’ll be clean and fun. Sunday morning the 26th is similar, glassy again with a 4ft south swell, period 10 seconds, energy at 532. A couple of nice, tidy sessions to start the weekend.
The surf dips a bit through the middle of the week (Monday the 27th to Wednesday the 29th) with smaller waves, but the wind stays glassy, so it’s still clean. The swell on Monday afternoon drops to 2ft but pulses up with a very long period of 17 seconds from the SW. That’s a groundswell, and at a reef break like Hiliduha, it’ll wrap in nicely, even if the height is small. Energy is moderate (394).
Now, the real standout is Saturday, August 1st. This is a beauty. Morning shows a 5ft SW swell with an 18-second period – that’s a long-period groundswell hitting the reef beautifully. The wind is glassy, and the energy is strong (1299). The afternoon pumps up to 5ft, period 17 seconds, and the energy jumps to 1540. This is excellent, clean, powerful surf for experienced surfers. The swell direction (SW) matches the optimum direction for this spot perfectly.
Monday, August 3rd is another big one. Morning brings a 5ft SW swell with a 17-second period, glassy winds, and very strong energy (2070). The afternoon is a touch bigger at 6ft with a clean cross-offshore wind. This is top-tier, but it’s likely pushing into expert territory (over 5ft, close to 8ft for the bigger sets).
Looking further out, Friday, August 7th gets serious. The swell jumps to 8ft in the morning with a 21-second period and a massive energy reading of 7088 – that’s very strong. The afternoon shows 10ft. This is only for experts, and the wind is cross-off, so it’ll be clean but powerful. The period is so long that at a reef break, it’ll be thick and lined up, but it’s going to be a handful.
Saturday, August 8th holds that 10ft swell in the morning with glassy conditions. The energy is still very strong (4650), but the afternoon gets a bit messy with a cross-onshore wind. If you’re a seasoned charger, the morning of the 8th is your window.
So, overall, the best on offer is the Saturday, August 1st session – that’s the one to circle. It’s got the right size, the perfect wind, and the swell direction is locked in. The second standout is the Monday, August 3rd window for those who want a bit more power. The 7th and 8th are for the big-wave crew only.
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.
