Alright, Rusty here, giving it to you straight for Hilisataro.
We’ve got a solid two weeks ahead, so no long flat spells to complain about. This is a reef setup that’s strictly for the advanced crew – it demands skill.
It all kicks off Saturday, July 4th afternoon. Clean 3ft S swell, 12-second period. Water temp is 86°, right on the money for the season. Combined energy is moderate (535). Solid start.
Sunday, July 5th cranks up. Morning has 4ft SSW with a very long 16-second period (856 energy) – proper groundswell. Light cross-off wind. Sunday afternoon is the big highlight: glassy flat, 4ft, 15-second period, 822 energy. That’s as clean as it gets.
Monday, July 6th fades a bit – 3ft SW, 16-second period, but the afternoon turns glassy. Good, not peak.
Tuesday, July 7th is a beauty. Tuesday morning: glassy, 4ft SW, 16-second period, offshore wind. That’s another standout. Tuesday afternoon is also offshore with 3ft.
Wednesday, July 8th swell jumps to 5ft plus. Morning has a cross-on breeze, afternoon is onshore. This is expert territory.
Thursday, July 9th morning is the pick of the bigger stuff: 5ft SSW, 14-second period, glassy, strong energy (1185). Raw and clean.
Friday, July 10th afternoon is glassy with 5ft SW, 15-second period, 1220 energy. Another top-tier, expert session.
Saturday, July 11th morning is dead calm and glassy with 5ft SSW (14 sec). Beautiful. The swell slowly drops through the next week but stays clean.
Wednesday, July 15th is dead calm again – 5ft SSW, 15-second period, 938 energy. A real gem mid-week.
Friday, July 17th is glassy and calm all day – 4ft SW, 15-second period, 720 energy.
The final standout is Sunday, July 19th afternoon: 3ft SSW but a massive 19-second period. At this reef, that’ll be long, clean, dedicated lines. Cross-off wind. A perfect way to end the forecast.
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.
