The Lowdown

Alright, Rusty here again. Let’s break it down in feet and miles per hour.

The first part of the run is a bit of a mixed bag. We’ve got some swell on the way to Hiliduha, but the wind doesn’t want to play nice straight away. The early part of the week is looking a little messy, but things start to clean up nicely as we go.

We kick off on Tuesday, July 21st. The swell is solid at 5ft out of the SSW, with a long period of 15 seconds, giving it some real grunt – the combined swell energy is 1069 (moderate to strong). But the catch is a light cross-onshore wind at 6 mph, which puts a bit of a bump on the surface. It’s surfable, but not the best it could be. That afternoon stays onshore, so nothing to get too excited about.

Then Wednesday morning, July 22nd, is where it gets interesting. The swell drops slightly to 4ft from the SSW, but the period is still a solid 13 seconds. The game-changer is the glassy wind from the ENE at 3 mph. It’s gonna be clean. That’s the kind of morning you want to be out there. The energy is still moderate at 637. The afternoon turns onshore and messy again, so that morning window is the one.

The rest of the week into the weekend is a bit of a struggle. The wind picks up from the SE and ESE, with cross-on conditions, and the swell gets smaller and a bit confused. It’s not a total write-off, but you’ll be searching for a clean face. The combined energy drops to around 283 to 569, which is weak to moderate.

Sundays are looking better. On July 26th, the morning has a glassy wind from the NNW at 3 mph, with a 3ft SSW swell at 13 seconds. It’s small, but it’ll be clean. The energy is 429 (moderate). That Monday morning, July 27th, is another glassy, calm session with 2ft of SW swell. Still small, but clean.

Now, the real standout is building right at the end of the month. Thursday, July 30th, is looking like the pick of the 16 days. We’ve got a 3ft SW swell with a monster period of 19 seconds – that’s proper groundswell. The energy is 1012 (strong), and the wind is glassy from the east at 3 mph. For a reef break like Hiliduha, those long-period lines should wrap in beautifully. It’s an advanced spot, so this is one for the experienced crew. The water temp is 86°F, which is about average for this time of year.

Friday, July 31st, is also a cracker. That same 19-second swell sticks around, dropping slightly to 4ft, and the energy is 1079. The Friday afternoon session is glassy again, with a 17-second period. That’s another one to mark on the calendar.

The first week of August keeps the swell alive. We’ve got a 4ft SSW swell on Saturday, August 1st, with a 16-second period and glassy conditions in the afternoon. The energy is 788. Sunday, August 2nd, has a clean cross-off wind from the NW at 6 mph, with a 4ft SW swell at 14 seconds. The energy jumps to 956. That’s clean and fun.

The biggest push of the whole forecast comes on Monday, August 3rd and Tuesday, August 4th. The swell is hitting 6ft to 6ft from the SSW, with 14-second periods. The energy is massive – 1478 and 1255, strong to very strong. This is expert territory, as the height is over 5ft. The wind is cross-on, so it’s not perfect, but there’s plenty of power.

The absolute best of the bunch, though, is Wednesday, August 5th. That morning we have a 5ft SW swell, a 16-second period, and a clean cross-off wind from the ENE at 6 mph. The energy is maxing out at 1523 (very strong). This is a serious session for experienced surfers. The swell size and direction are well-matched to the optimum for Hiliduha, and the clean wind makes it a standout.

Crowds are possible at Hiliduha, as it’s sometimes crowded. It’s a fairly consistent reef break, so it doesn’t fire every day, but when it does, it’s worth it.

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.
