Table - best surf conditions forecast for Hilisataro over the next 16 days.
Alright, Rusty here. Let’s dig into it.
Right off the bat, there’s surf on the menu from Wednesday July 8th – no dead time. The whole run looks clean, with a long-period SSW groundswell holding steady and pulsing for days.
Wednesday the 8th opens with 1.5m of SSW swell on a 15-second period and a combined energy reading of 1088 – decent energy, and glassy in the morning. The wave quality is very good right out of the gate. Afternoon goes cross-off from the WSW, but still holds up.
The standout is Friday morning July 10th. Combined energy climbs to 1374, with 1.6m of southwest swell and a 16-second period – that’s proper groundswell. Glassy conditions all day. The swell direction lines up perfectly with Hilisataro’s preferred SW exposure. Crowds are listed as “sometimes” – it’s an advanced reef break, so take note.
Saturday the 11th through the start of the next week drops to 1–1.3m, energy falling into the hundreds, but mornings stay glassy and clean. Tuesday July 14th afternoon offers another gem: 1.2m SW swell on a 17-second period with energy at 1422. That is a very long-period groundswell – good for shape but the take-off zone will be sharp.
Wednesday July 15th morning stays strong with 1.6m SSW on a 16-second period and 1334 energy – glassy.
Into the second week, Monday July 20th morning shows 1.3m SSW on a 17-second period at 1282 energy, and that afternoon delivers the highest combined energy of the whole period at 1507 with 1.5m SSW on a 16-second swell. Winds are glassy both morning and afternoon. That’s the second major highlight – a little further out so a bit less certain, but the ingredients are all there.
So the top calls are Friday July 10th and Monday July 20th afternoon. Both have that long-period groundswell, clean glass, and direction right in the zone. For an advanced reef break, when it’s over 1.5m you need to be on your game. This stretch of consistency at Hilisataro is rare. Don’t sleep on it.
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.
