The Lowdown
Alright folks, Rusty here. Let's get into it.
We're looking at a solid stretch of south-west groundswell hitting Hiliduha, a reef setup that's strictly for the advanced crew. The water is sitting at 86°, which is about normal for this time of year, so no surprises there.
The first few days are a bit of a tease. Tuesday 28 July and Wednesday 29 July are small, with waves around 2ft to 3ft. The energy is light (440 to 513), so it's not really worth paddling out for. There are a few glassy windows on Tuesday afternoon and Wednesday morning, but the swell just isn't there.
Thursday 30 July sees the swell build a touch to 3ft, but the period is a very long 19 seconds. That's a groundswell for sure, but at a beach break? It'll be too straight and hard to get into. The cross-on wind won't help. The energy is moderate (899 to 935), but conditions are marginal.
Now, Friday 31 July morning is where things start to get interesting. The swell is 4ft from the SW with a 17-second period, and the wind is light and cross-off from the east. That's clean. The energy is solid at 1030. This is a good, clean option for experienced surfers.
Saturday 1 August morning is a standout. The swell is 4ft from the SW, period is 17 seconds, and it's glassy with a light NE breeze. Energy is strong at 1254. The sets will be clean and well-shaped. This is a great morning to be out. Keep in mind, crowds are possible here.
Sunday 2 August morning is another beauty. Same swell size, 4ft, 16-second period, and glassy again with a light ENE wind. Energy is 1116. Another clean, classic morning session.
Monday 3 August morning is flat calm – zero wind and glassy. The swell is 5ft with a 15-second period. Energy is 948. It's a very good session, but the afternoon gets messy with a cross-shore breeze.
Tuesday 4 August morning brings offshore wind from the north, 4ft swell, and a 16-second period. Clean and excellent. The afternoon sees the swell bump to 5ft, but the wind picks up to 12 mph from the NW, making it a cross-off. That's still clean, but the energy is up to 1380.
Wednesday 5 August is a solid day. The morning has 5ft swell with a 15-second period and light cross-off wind. The afternoon is the real treat: 4ft swell but with a very long 20-second period, and energy at 1888. That's a proper groundswell, and the reef at Hiliduha will love it. Clean cross-off wind all day.
Thursday 6 August and Friday 7 August see the swell jump up. Waves are 7ft to 8ft, which is expert territory. The wind is a consistent cross-off, but it's getting strong – 16 to 22 mph. The energy is huge (2163 to 2867), but the wind is making it a battle. It's more of a kite-surfing show than a paddle session.
Saturday 8 August is similar, with 7ft to 7ft swell and strong cross-off wind. The energy is still massive (1911 to 2254). Hard work.
The best on offer is Sunday 9 August. The morning has 7ft swell from the SSW with a very long 18-second period, and the wind is light offshore from the NNW. The energy is pumping at 4328. Conditions are clean and excellent. The afternoon is also excellent, with 8ft swell and a 17-second period, and a moderate cross-off breeze. This is the biggest, cleanest, and most powerful swell of the whole run. Only for experts.
Monday 10 August and Tuesday 11 August are still excellent, with waves dropping from 7ft down to 6ft, all clean and cross-off. Energy is still very strong (1642 to 2439). Good follow-up days.
Wednesday 12 August sees the swell back up to 8ft, but the wind swings cross-shore at 9 to 12 mph, creating some chop. The energy is huge (3046 to 3346), but the conditions are only marginal.
So, to sum it up: the first few days are a slow start, but from Friday 31 July through to Tuesday 11 August, there are plenty of good to excellent sessions. The absolute standout is Sunday 9 August – mark it in your calendar.

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.
