The Lowdown
G’day, Rusty here. Let’s be straight with you – this forecast’s a bit of a heartbreaker if you’re chasing clean, rippable surf. Sanur Reef is the only break on the cards, and for the first week or two, everything’s pretty average. We’ve got heaps of swell energy pounding in, but the wind’s just not playing ball and the reef’s pretty sheltered and inconsistent, so we’re in for a long wait before anything really comes together.
The water temp is sitting at a balmy 80°, which is pretty much normal for this time of year – nothing weird there.
We start with Thursday, the 6th of August. Don’t get too excited. Swell’s a solid 6 ft from the SSW with a long 17-second period, and the combined energy is a beastly 2203, but it’s cross-on from the ESE at 16 mph, making a mess of things. Poor surf conditions right through to Sunday the 9th – just choppy, bumpy lines. Not worth paddling out.
Monday the 10th sees a shift. Still cross-on, but the wind eases to 9 mph from the SE, and the swell cleans up a touch. By Monday afternoon, we’ve got 10 ft from the SSW, period still holding at 18 seconds – that’s proper groundswell – and the energy’s up around 5780. It’s still only marginal, but there’s a chance of a few bombs if you’re patient. Not the best of the window though.
The real standout – and I mean, the only time I’d really recommend grabbing a board – is on Wednesday the 19th of August. Get there in the morning. We’ve got 8 ft SSW swell with a 17-second period – nice and long, makes for proper shaped waves – and the wind swings to a light SSW at 6 mph, which is cross-offshore and clean. The energy reading is 3057 – solid but not out of control. Conditions are described as excellent for experienced surfers, and that’s not a throwaway line. That morning is your best bet by a mile. Afternoon gets ruined by the SE wind again. If you can score that Wednesday morning window, you’re in for some clean, powerful reef waves.
After Wednesday, Thursday and Friday the 20th and 21st look marginal again with onshore wind, but there’s another pulse of 10 ft SSW swell on Friday the 21st – just hope the wind chops out. For the first week of August, don’t bother. Hold out for that Wednesday the 19th morning session at Sanur Reef.
Over and out – 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.
Sanur Reef is 6 km (4 miles) from Denpasar. If you plan a holiday in Sanur - Bali, look for hotels and other accommodation in Denpasar. Denpasar has rooms for a wide range of budgets as well as car hire and transport links.
