The Lowdown
Alright folks, Rusty here. Let’s have a look at the forecast for the next couple of weeks. Straight up, I gotta be honest with you – this is a tough one. The surf is coming, but the wind just won't play nice, and that’s going to mess things up.
We’re looking at Sanur Reef, a sheltered reef break that needs a south swell to work. The swell is coming in from the SSW, which is pretty much bang on its optimum direction, so that’s the one piece of good news. The water is sitting at 81°F right now, which is about average for this time of year, so no surprises there.
The problem is the wind. For pretty much the entire 16-day run, it’s hammering from the ESE to SE at 12 to 19 mph. That’s a cross-on wind for this spot, and it’s going to leave the surface choppy and messy. The swell is there, but the quality is going to be poor. It’s a real shame, because there’s some decent energy in the water.
The first real pulse of swell we see kicks off around Saturday, July 20th. The wave energy climbs to a moderate 2046 (combined energy of all swells directed here) with a 7ft SSW swell, but that 12 mph cross-on breeze is just going to ruin it. It’s a marginal call at best.
Things get a bit more interesting on Monday, July 28th. The swell picks up again, with a long-period 17-second swell from the SSW at 5ft. The energy is strong at 1511 (combined energy of all swells directed here), but the wind is still a fresh 16 mph cross-on, which will make for lumpy, difficult conditions.
The biggest push of the whole forecast comes right at the end, on Saturday, August 2nd. We’re looking at a solid 8ft SSW swell at 18 seconds, with very strong energy readings of 3504 (combined energy of all swells directed here). That’s a proper groundswell, and with that period, it’s going to have some serious power. But again, the wind is howling at 19 mph from the ESE, a fresh cross-on. For a reef break, the long period and strong wind might make it a bit of a washing machine and honestly, that size and those winds, it’s really only one for the experts.
The best of a bad bunch? If I had to pick one, I’d say the Sunday morning, July 26th session. It’s the only time we see an offshore wind, even if it’s just a moderate breeze. You’ll have a 6ft, 8-second swell from the SE. The period is short, so it won’t have the punch of a groundswell, but with the wind offshore, it’s going to be the cleanest wave we see all forecast. The wave energy is moderate at 814 (combined energy of all swells directed here), and it’s the only real chance for a half-decent wave. For a sheltered spot like this, those offshore conditions are gold.
Other than that, it’s a pretty bleak outlook. The wind is just relentless. For a break that’s inconsistent at the best of times, this is a particularly frustrating stretch. If you’re a beginner, the swell stays under 5ft for most of the first week, but the wind will make it a fight. After July 28th, the swell gets over 8ft, which is expert-only territory, and the wind is still blowing. Honestly, this setup looks more interesting for kite surfing than paddle surfing for most of the run.
Stay patient, crew. The swell is there, but the wind isn't. It tends not to stay this poor for long, so keep your eye on the forecast.
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.
