Alright, Rusty here. Let’s talk about what’s coming up for Hiliduha.
Right off the bat, the first few days are a bit of a write-off. Sunday the 12th through Tuesday the 14th are looking pretty marginal with small, weak swell and questionable conditions. The combined energy is low to moderate (around 478 to 1290) and the winds are mostly onshore or cross-onshore, so don’t bother paddling out just yet. You’ll be sitting there waiting for nothing.
The first real glimmer of hope hits on Wednesday morning, July 15th. We’ve got a clean 5 ft SSW groundswell with a solid 16-second period, and the wind is dead glassy. That’s a proper window for experienced surfers. The water is sitting at 86°, which is about normal for this time of year. The afternoon stays glassy, dropping slightly to 5 ft but still clean. This is the standout of the first week.
Thursday the 16th morning is still very good with 5 ft SW swell at 15 seconds and glassy conditions, but the afternoon gets a bit bumpy with cross-onshore wind. Things taper off again through the rest of the week until Saturday the 18th morning, which offers another glassy window with 4 ft SW swell, but it’s not as consistent.
Now, hold onto your board. The real standout is Monday, July 20th. We’re looking at a solid 6 ft to 6 ft SSW groundswell with a very long 18-second period, and the wind is glassy all day. The combined energy is pumping at 1834, meaning strong, powerful waves. This is excellent for experienced surfers. It’s a reef break, so that long period will wrap in nicely. Tuesday the 21st keeps the good run going with 5 ft SSW swell and glassy conditions, though the energy drops a bit.
After that, the swell backs off into the end of July, but there’s another little gem on Saturday the 25th afternoon. A 3 ft SSW swell with a 20-second period – that’s a very long period groundswell – and glassy conditions. It’s small, but the energy is surprisingly high (1149) and the quality is top-notch for those who know how to read a long-period wave.
Overall, there’s a big gap of poor surf from the 12th to the 14th, then a couple of clean windows mid-week, and the absolute best is the 20th and 21st. Don’t sleep on the 25th afternoon either.
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.
