The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' for Hiliduha. We've got a solid run of swell on the cards, a real treat for the experienced crew out there.

The overall pattern is a drawn-out, powerful SSW groundswell train that kicks off this weekend and just keeps on giving, with a few real standout windows of glassy, clean conditions for those who know what they're doing. This is not a beginner's wave right now; the size is serious and the power is up there, with wave energy readings in the thousands (1800+ to over 4400) for most of the first week, so you're looking at strong to very strong energy in the water.

First up, the standout is Sunday morning, the 9th of August. Hiliduha (a reef break, advanced only) will be seeing a clean 6ft SSW groundswell with a period of 15 seconds, and the wind is dead calm, glassy as a mirror. The wave energy is pumping at 1802, and it's a classic morning for the experts. This is the one to circle on the calendar. The water temp is about average for this time of year, nothing wild to report there.

The action keeps rolling into Monday the 10th. The morning is a bit cross, but Monday afternoon switches back to glassy conditions with a 6ft SSW swell at 14 seconds and wave energy actually jumping up to 2217 – that's a lot of power moving through. Another great session for the advanced crew.

Tuesday the 11th gets bigger, with the morning seeing 6ft SSW at a very long 19-second period (3187 energy). It's cross-on shore though, so it's a bit lumpy, but there's so much push in the water it'll still be a handful. Wednesday the 12th morning is back to glassy with a clean 6ft SSW groundswell (2030 energy). The rhythm is there.

Thursday the 13th is a real beauty. Dead calm in the morning with a 5ft S swell at 13 seconds (1162 energy) and glassy conditions holding through the afternoon with a slight air but still glassy. This is a day for getting some clean, lined-up waves without the massive grunt of the bigger days.

Friday the 14th morning is another glassy one, dead calm, with a 6ft SSW groundswell at 16 seconds (1865 energy). That's a lot of clean power.

Things start to ease off a touch over the weekend of the 15th and 16th, with smaller 5ft to 4ft S swells and more cross-onshore winds, but still surfable for those in the know. By Monday the 17th, the swell dips right down to under 3ft, so don't expect much there.

Now, here's the real long-range gold. Look at Thursday the 20th of August. Morning sees a solid 8ft SSW groundswell at 16 seconds, but the wind is from the NE at just 5 km/h and glassy. The wave energy is at 3287. This is a proper, powerful, clean day for experts only. It's over two weeks out, so keep an eye on it, but the signs are excellent.

A heads up: from the 18th to the 19th, the swell jumps back up to 7ft to 8ft with cross-onshore winds, so it's going to be a bit of a washing machine out there. That's expert territory for sure, and the conditions won't be as clean as the glassy days.

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.
