The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Hilisataro over the next couple of weeks.
Right now, the surf is pretty flat, so we’ve got a bit of a gap to wait through. The first real chance to get wet won’t be until Saturday the 25th of July, but even then it’s small. The standout period is definitely the second week, from late July right into early August, when the swell really kicks in and the conditions line up.
For the first few days, Thursday the 23rd and Friday the 24th are write-offs. The swell is tiny and the wind is all onshore or cross-on, making for poor, messy conditions. You’d be wasting your time.
Things start to look up on Saturday the 25th of July. The morning is still a bit messy with a cross-shore breeze, but the afternoon turns glassy. We’re looking at a clean 4ft south swell, period around 10 seconds. The combined energy is moderate (510). It’s not big, but it’s clean and rideable. Sunday the 26th continues the trend with a glassy morning, 4ft south swell (469), perfect for a longboard or a funboard. The water temp is sitting at 86°, which is about average for this time of year, so no wetsuit needed.
The real magic starts to brew towards the end of the month. From the 30th of July, the swell direction shifts to the southwest and the period jumps right up. Thursday the 30th sees a 3ft to 3ft SW groundswell with a period of 18 to 19 seconds. That’s a very long period, and it’s glassy all day. The energy is getting strong (943 to 948). This is the kind of swell that will wrap into Hilisataro with real power and shape. This is a reef break, so a long period SW groundswell is exactly what it wants.
The absolute peak of this run looks like Saturday the 1st of August. The morning brings a clean 5ft SW swell with a 18-second period, glassy conditions, and a combined energy of 1572. That’s a strong, powerful swell. This is for experienced surfers only – over 5ft and it’s too much for beginners. The afternoon stays glassy and calm at 5ft. This is the best on offer for the whole forecast.
The standout without a doubt is Hilisataro on Saturday the 1st of August. We’ve got a solid 5ft SW groundswell (18s period), with glassy conditions all morning. The energy is strong (1572). It’s going to be clean, powerful, and lined up. This is a day for the advanced crew. It’s a reef break that’s fairly consistent and fairly exposed to the SW, so it’ll be handling that swell well. Just be aware that crowds are possible here, so get in early.
The surf stays good right through to the 7th of August, with excellent conditions for experienced surfers on the 3rd and 4th, pushing up to 6ft and 7ft on the 4th. That’s big, powerful stuff with massive energy (2526), and only for experts. The wind stays light and mostly glassy or cross-offshore through this whole period. The long-range stuff from the 7th is still promising, but a bit less certain.
So, to sum it up: wait through the flat start, enjoy the small clean waves on the weekend of the 25th, but clear your calendar for the 1st of August. That’s the one.
Rusty.

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.
