The Lowdown
G'day, Rusty here. We’ve got a decent run of swell on the cards for Hiliduha over the next couple of weeks. This spot is a pretty exposed reef setup, so it needs a solid SW groundswell to get going, and lucky for us, that’s exactly what’s lining up. The water’s sitting at a warm 86°, which feels a touch warmer than normal for this time of year, so a spring suit will be plenty.
Things kick off Friday the 11th, but it’s not the best start. Morning has some 5ft SW swell with a 16-second period, and that’s proper long-period groundswell with solid energy (1628). Problem is, it’s a cross-on breeze and there’s a risk of thunderstorms, so the surface is going to be bumpy. It’s a marginal call, but there are waves to be had if you’re keen.
The first real standout comes Saturday the 12th afternoon. The swell drops a little to 5ft but the period stretches to 19 seconds, so it’s got that deep ocean push. The real story is the wind – a light cross-off from the NE, which will clean the face right up. The combined energy is pumping at 2755, and it’s calling for excellent conditions for experienced surfers. This is your pick for the first week.
Sunday the 13th morning is a gem. The swell builds to 7ft from the SW with a 17-second period, and the wind is absolutely dead calm—glassy conditions. That’s about as clean as it gets. Energy is strong at 2657. This one’s for the crew who can handle a bit more size; anything over 8ft gets expert-only, and 7ft is right on the edge for beginners. Hold onto it.
The middle of the week gets a bit average. Monday through Tuesday has consistent 6-6ft SW swell, but the wind swings around to the SE, putting a cross-on chop on the surface. It’s surfable but not pretty. Wait for Wednesday the 16th morning. The swell drops to 5ft, but the wind goes glassy again with a light ESE breeze, making for excellent conditions once more. Energy is moderate at 1115.
Thursday the 17th sees the swell back up to 6ft, but the cross-on breeze returns, so it’s a bit of a mixed bag.
Looking into the second week, the outlook gets promising again. Friday the 18th morning is glassy and small at 4ft, but that clean surface and a 13-second period means it’s good for a longboard. The real highlight of the second half is Saturday the 19th afternoon. The swell jumps to 6ft from the SW with a 17-second period, and the wind goes dead calm—glassy perfection. Energy is strong at 1725. Then Sunday the 20th keeps the run going: 6ft SW swell, glassy in the morning with a NNW wind, and clean in the afternoon with a light cross-off. Both sessions are excellent for experienced surfers.
The run of good swell continues into the following week. Monday the 21st afternoon goes glassy again with 6ft SSW swell, and Tuesday the 22nd morning is dead calm with 5ft. By Wednesday the 23rd afternoon, it’s another glassy session with 5ft from the SSW and a 16-second period. That’s a solid, clean option.
The last standout of the whole outlook is Saturday the 26th. Morning has 5ft SW swell with an 18-second period, glassy with a light NNE breeze. Energy is 1556. The afternoon steps it up to 5ft with a 17-second period and dead calm conditions. That’s a beautiful way to close out the forecast.
Overall, Saturday the 12th afternoon and Sunday the 13th morning are the absolute best of the run – size, period, and clean wind all lining up. For the second week, Saturday the 19th afternoon and Sunday the 20th are the standouts, but all those glassy windows from the 18th onward are worth a look.
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.
