Table - best surf conditions forecast for Hilisataro over the next 16 days.
Alright, Rusty here. Let's break down what's coming.
So, the first few days are a bit of a mess with stormy conditions and tricky winds, but don't worry, it turns on big time later in the period. There's a proper run of clean surf on the horizon.
The absolute high point is Monday the 20th and Tuesday the 21st. That's when a strong, long-period groundswell hits. The wave energy is cranking, with values hitting 2499 and 2262. That's serious power. The swell sits around 7ft from the SSW, and with flat calm, glassy conditions on both Monday sessions, Hilisataro is going to be offering up some excellent, clean lines. This one is for the experts only. Anything over 5ft is getting big, and at 7ft, it’s a proper handful for the advanced crew. The period is long, around 17 seconds, so you'll get powerful, well-defined waves with plenty of punch and longer lulls between sets.
Before that, the middle of the week is solid too. Wednesday the 15th and Thursday the 16th are well worth a look with clean, glassy conditions and a nice 5ft or so SSW swell. The period is still long, so the waves will have good shape. It's a bit more manageable than the Monday spike. The water temp is sitting right about normal for this time of year.
Later on, around the 24th and 25th, the swell drops right off to around 3 to 3ft. It'll be clean and glassy, so fun for a longboard or a small-wave thruster, but it's not going to get the heart pumping. The long period will still help those little waves hold their shape.
Just a heads up, Hilisataro can see a few people out on the better days, so expect some company on the peak sessions.
But for the real deal, circle Monday the 20th and Tuesday the 21st of July. If you've got the nerve and the skill, that's the time to be out there.
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.
