The Lowdown
G’day, Rusty here. Let’s have a look at what’s coming our way for Hilisataro.
Right now, the surf is pretty flat, but hold tight – it’s not staying that way. There’s a solid window of building swell and clean conditions that really kicks off towards the end of this week and gets proper exciting into early August. The standout period is absolutely the morning of Sunday, the 2nd of August, but let’s walk through it day by day.
Monday the 27th and Tuesday the 28th of July are nothing to write home about. Tiny, weak swell around 2ft to 3.3ft from the south and southwest, with some storm clouds and tricky cross-onshore winds. Not worth paddling out for unless you’re desperate for a splash. The only highlight is Tuesday morning when it goes glassy for a moment, but there’s almost no wave energy.
Wednesday the 29th of July shows some promise – the morning is glassy with a 3ft southwest groundswell riding in at a nice long 15 seconds. The combined energy is moderate, and the conditions look clean. Still small, but if you’re after a cruisy session, this is the first decent window.
Thursday the 30th and Friday the 31st of July sees the swell bump up a touch to 3.3ft to 3.6ft from the southwest, but the winds get messy – cross-onshore and onshore, so the surface gets chopped. Then Friday afternoon everything flips. The wind drops to glassy, the swell holds at 3.6ft from the southwest with a 16-second period, and the combined energy is strong. This is one of the first real highlights – clean, groundswell lines with that long period making for proper shaped waves at this reef. Just be mindful of the crowds as they can pop up here sometimes.
Saturday the 1st of August brings a 4.3ft southwest swell, but winds are cross-onshore both morning and afternoon. The energy is building, but the surface isn’t clean enough to make it a standout.
Now, Sunday the 2nd of August – this is the one. The morning is absolutely magic. Calm winds, glassy as a mirror, 4.3ft of southwest groundswell with a 16-second pulse, and strong energy. This is excellent surf for experienced surfers. The direction is from the southwest, which lines up perfectly with the optimum for this reef. The water temperature is about average for the time of year, nothing unusual there. If you can get out, this is the session to chase. Sunday afternoon holds clean with a glassy 3.6ft from the SSW, still very good, but the morning is the winner.
Monday the 3rd of August sees the swell push up to 4.6ft to 4.9ft with cross-offshore winds, so it’s clean and groomed. Strong energy. This is very good, but the bigger, cleaner days are just ahead.
Tuesday the 4th of August is a big one. The morning has a 3.6ft southwest swell with offshore winds from the northwest – clean and lined up. Then the afternoon fires up: 5.6ft from the SSW, 16-second period, and offshore northwesterlies. That’s excellent, expert-level surf. Not for beginners – 5.6ft is pushing it – but for experienced surfers, this is gold.
Wednesday the 5th of August keeps the goodness rolling. Offshore winds from the NNW all day, 4.9ft to 5.2ft of south-southwest groundswell, and high-end energy. Glassy and clean throughout. Another day for the crew who know what they’re doing.
Thursday the 6th of August delivers a serious pulse. Morning sees 5.9ft from the SW with a long 18-second period, glassy winds, and a massive energy reading. Afternoon holds 6.2ft from the SSW at 17 seconds with even higher energy. This is big groundswell for the reef – long-period waves like this can break really well here because it’s a reef setup. The water stays clean under light winds. Experts only at this size, but the quality is off the charts.
Friday the 7th of August is still pumping with 5.6ft to 6.2ft of SSW groundswell, glassy and cross-offshore winds, and high energy readings. Very high quality, but the swell is dropping slightly by the afternoon. Still an excellent day.
Saturday the 8th of August gets tricky. The swell holds at 4.9ft to 5.9ft, but the wind swings onshore from the east and southeast. The energy is extreme, but the surface gets messy and the tide might be questionable. This looks more interesting for kite surfing than paddle surfing.

Information about the Hilisataro Surf forecast
The above surf forecast table for Hilisataro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hilisataro can be found by selecting the local surf guide option on the grey menu. Our Hilisataro 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 (Hilisataro) 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 Hilisataro 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.
