The Lowdown
Alright, listen up. We’ve got a bit of a mixed bag ahead for Hiliduha. This is an advanced reef break, and it’s exposed to the SW swell, which is good news because most of the swell we’re seeing is coming from that direction for the next couple of weeks. It’s a fairly consistent spot, but it can get crowded sometimes.
The water temperature is sitting at 86°, which is about 1° warmer than usual for this time of year. That’s a little warmer than average, but nothing too wild.
The first few days, starting Sunday the 2nd, are a write-off. We’ve got a cross-shore wind and a lot of storm activity. The swell is small, around 3ft, and the energy is weak (1125). The tide and wind just aren’t playing ball. Skip it.
Monday the 3rd isn’t much better. The swell pushes up to 5ft with a long 15-second period from the SW, but the wind is still cross-shore and the rain is back. The energy is moderate (949), but the conditions are just too messy.
Finally, we get a window on Tuesday the 4th. The morning is looking like a true standout. The wind swings offshore from the NNW, it’s light, and the swell is a solid 6ft from the W. The period is a 10-second wind swell, but the energy is pumping hard at 1809. This is excellent for experienced surfers. The waves will be clean and powerful. But this is a big one, over 5ft, so it’s for the crew who know what they’re doing. The afternoon drops off a bit, but it’s still clean.
The best part of the whole forecast, though, is the run from Saturday the 8th through to the end of the second week. We’ve got back-to-back-to-back glassy conditions. Saturday the 8th morning kicks off with a light cross-offshore breeze and a 7ft SSW swell at 16 seconds. That’s a very long period groundswell. The energy is 2605, which is strong. The afternoon gets even better with an offshore NNW wind, glassy, and 7ft swell. This is the pick of the first week.
Then Sunday the 9th is perfect. Glassy, offshore, 7ft SSW swell. This is what you wait for. The energy is 1792, so it’s not as massive as the Saturday, but the conditions are immaculate.
The middle of the second week, from the 10th to the 13th, gets a bit average. The wind turns onshore or cross-onshore from the SE, and the swell drops off. The wave quality is marginal. The 14th and 15th, however, are looking like another epic run. Friday the 14th is glassy with a 4ft to 4ft S swell with a very long period of 18 seconds. The energy is 1733, which is moderate, but those long-period lines will be clean and perfect for the reef. Saturday the 15th is the absolute standout of the entire 16 days. The morning is glassy, 7ft S swell, with 2887 energy. But the afternoon… the afternoon is a 5ft SW swell with a 20-second period and 3099 energy. The wind is calm. It’s glassy. That is a dream session for the advanced crew.
The last few days, the 16th and 17th, stay glassy and clean with solid 5ft to 6ft SSW swell. The energy is strong right through. It’s all for the experienced surfer, though. If you’re a beginner, this break is not for you, especially with the swell over 5ft for most of the good days.
So, to sum it up: the first few days are a bust. The standouts are the morning of Tuesday the 4th, and the absolute peak of the window is the afternoon of Saturday the 15th. The whole second week has a lot of glassy, clean conditions, but the 15th is the one to circle.

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