The Lowdown
Alright crew, Rusty here. Let’s break down what’s happening for the next couple of weeks.
To be straight with you, the first four days are a total loss. From Monday the 24th through Thursday the 27th, the wind is howling cross-on, and the surf is just choppy and ugly. There’s swell, but it’s not rideable in any decent way.
The first real chance to get wet is Thursday the 27th of August. The wind drops to a gentle breeze, and the ocean goes from “choppy” to “fairly choppy.” The swell is about 3ft from the SSW, with a 16-second period, giving it moderate wave energy (1007). That’s a long-period groundswell, so it’ll have some punch, but it might be a bit straight for the beach. On a reef like Sanur, it could be okay.
The one to really get excited about is Friday the 28th of August. The morning shows a solid 8ft of SSW swell, with a 16-second period, and the energy is pumping (3076). The wind is still a gentle cross-on, so the conditions are only “fairly choppy” – not great, but workable. This is the biggest swell of the whole outlook. At 8ft, that’s expert-only territory, especially on a reef. That’s the day to be ready for.
After that, it tails off. Saturday the 29th and Sunday the 30th are back to poor conditions as the wind picks up again. The swell is 4ft to 6ft, but the chop ruins it.
The second week, from the 31st of August to the 8th of September, is a real grind. The swell stays around 5ft to 6ft from the SSW, with periods between 13 and 18 seconds. The energy is moderate to strong (between 917 and 1928). The problem is the wind never lets up. It’s a steady cross-on breeze, and the surf is either “poor” or “marginal” at best. There’s a tiny bright spot on the afternoon of Tuesday the 8th of September, when the wind goes cross-shore and the chop eases a little, but that’s way out there and not something to bank on.
The water is sitting at 80°F, which is about average for the season, so you’re fine in a spring suit.
If you’re picking one day, it’s Friday the 28th of August for the size and power. The rest of the time, it’s a fight against the wind. The reef can still turn it on, but it’s going to be a waiting game.
Rusty.

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