The Lowdown
Alright, let’s take a look at what we’ve got cookin’.
Honestly, it’s a tough stretch ahead for Nyang-Nyang. This is a powerful, exposed reef that demands the right conditions, and over the next 16 days, we just aren't getting that magic alignment. The setup is big on swell but terrible on wind. The water temp is running at 79°, which is pretty standard for this time of year, nothin’ unusual there – just your average warm tropical bath.
Right now, starting on Sunday the 9th, we’ve got a solid 7ft SW groundswell with a very long 16-second period pumping in, but the problem is the 16 mph SE cross-onshore wind. It’s tearing that swell apart, making it all messy and choppy. The combined wave energy is enormous, at 2229, but that energy is wasted with the wind howling like this. The score reflects that – it’s just poor.
Monday the 10th is more of the same: a 6ft swell with a super-long 19-second period in the morning jumps the energy up to 4058, and by the afternoon it's a 10ft wave with 18 seconds and an energy of 5976. But again, that cross-onshore ESE to SE wind is on it, ruining any chance of a clean face. This is a real shame, because the size and period are there, but the wind is the enemy.
The standout (and I use the term loosely) is Tuesday morning, the 11th. We finally get a bit of relief in the wind, swinging SSE and dropping to 9 mph, which is a light onshore wind. The swell is a solid 10ft at 17 seconds from the SSW, which is right in the optimum direction for Nyang-Nyang. The energy is a staggering 5583. This is big, powerful, long-period groundswell. For an advanced surfer at this reef, this is the session that could fire off some big, lined-up walls. It’s still not glassy, but it’s the cleanest we see by far. Keep in mind though, 10ft is firmly in expert-only territory. The afternoon gets a bit windier and rougher again.
After that, from Wednesday the 12th right through the rest of the first week and into the second, the pattern sticks: a lot of big swell, often over 8ft, with periods between 15 and 17 seconds, and relentless 12-19 mph cross-onshore winds from the SE or ESE. The energy readings are consistently in the strong range, like the 5976 on the 10th or the 5043 on the 19th, but the surf quality is rated as poor or marginal at best. It’s just lumpy, blowy, and not enjoyable. For a beach break, this kind of wind and over 8ft swell would make for better kiting than paddling, but Nyang-Nyang is a reef, so you’d just be getting thumped in a washing machine.
So, to be straight with you: Tuesday morning, the 11th of August, is the only real window to even think about. It’s big, it’s clean-ish, and the swell direction is perfect. Everywhere else in this outlook is a write-off due to wind. It’s a long run of poor conditions, but in an exposed spot like this, the forecasts can flip. We’ll keep an eye on it.

Information about the Nyang-Nyang Surf forecast
The above surf forecast table for Nyang-Nyang provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nyang-Nyang can be found by selecting the local surf guide option on the grey menu. Our Nyang-Nyang 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 (Nyang-Nyang) 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 Nyang-Nyang 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.
Nyang-Nyang is 16 km (10 miles) from the city of Kuta. If you plan a holiday in The Bukit - Bali, look for hotels and other accommodation in Kuta. Kuta has rooms for a wide range of budgets as well as car hire and transport links.
