The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Hiliduha over the next couple of weeks.
The first few days are a bit of a write-off. We've got a stormy risk-tstorm theme running through this weekend and into Monday, with a cross-onshore breeze messing up what little swell there is. The wave energy is weak, reading only 662, and the water's sitting at a warm 86°, which is about normal for this time of year. You'll be looking at choppy, poor surf, so don't even bother paddling out on Saturday the 5th or Sunday the 6th. It’s a slow start.
We finally see a glimmer of hope on Tuesday morning, the 8th. The wind swings around to a clean, cross-offshore breeze, and we get a nice 3ft SW groundswell with a long 18-second period. The combined energy jumps to 1046 – moderate, but good shape. That's a session for the advanced crew, but it’s clean.
The real standout, though, is Thursday the 10th. This is the one to circle on your calendar. We’ve got a solid SW groundswell, 5ft to 5ft, with a period of 16 to 17 seconds. The wind is glassy all day – absolutely dead calm in the afternoon. The combined wave energy is pumping at 1261 and then 1469. That’s proper, clean, excellent surf for experienced surfers. This is your best bet for the whole outlook.
After that, the swell hangs in through the weekend and into the second week. Monday the 14th and Tuesday the 15th both offer clean, glassy mornings with 5ft SW groundswell, though the energy dips a bit (1232 and 1187). Still, those are solid sessions.
By Wednesday the 16th, things get serious again. The swell pumps up to 7ft to 7ft from the SSW, with a long 17 to 18-second period. The energy is strong – 2259 to 3204. That's big, powerful, and only for the experts. The wind is clean, so if you’ve got the skills, that Wednesday afternoon into Thursday the 17th will be firing.
The final weekend, the 19th and 20th, looks promising with glassy mornings and a solid 6ft to 7ft SSW swell. The 20th has a 20-second period, which is very long, so the waves will have heaps of energy (2052) but will be better suited for the point or reef setup here at Hiliduha rather than a beach break. Keep that in mind.
So, to wrap it up: ignore this weekend, get excited for next Thursday the 10th (the absolute standout), and keep an eye on the big stuff around the 16th and 17th for the experts.
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.
