The Lowdown
Alright, Rusty here again. Let's break it down for you in feet and miles, because that's how we feel it.
We're looking at Tandjung-Lefts, a reef break for the advanced crew. It's consistent, but the wind is a real pain right now. Water temp is about what you'd expect for this time of year.
For the first week, the wind is howling out of the ESE and SE at 9 to 15 mph, which is cross-onshore. That's going to chop the surface up bad. The swell is a solid 5 ft to 7 ft, with a long period of 14 to 19 seconds, so there's a ton of energy moving. The combined energy values are huge, like 1655, 1624, and 2660, but it's all for nothing with that wind.
Wednesday the 2nd and Thursday the 3rd are a washout. Swell is 6 ft and 5 ft, but the wind is ruining it. Friday the 4th is a little better with the wind dropping to 9 mph, but the swell drops to 3 ft to 4 ft, and the energy is moderate. The call is "marginal" at best.
The weekend of the 5th and 6th sees the swell bump back up to 6 ft to 7 ft. The energy is strong, 1572 and 1824, but the wind is still cross-on. It's frustrating, because the ocean has the push, but the surface is a mess.
The most promising window is around the 10th of September. The wind shifts to a cross-shore, not cross-on. The swell is 6 ft, period 17 seconds, and the energy is 2198. The wind is a gentle breeze from the SSE, so it's a cross-shore with a slight chop. For an advanced reef, that's your best bet.
After that, the 15th and 16th of September show some hope. The wind drops to a light breeze of 6 mph from the SE, still cross-on, but very light. The swell is 6 ft to 6 ft, period 15-16 seconds, with solid energy. The light wind will make the surface a lot more user-friendly.
The standout session? Thursday the 10th afternoon. It's got the best wind of the whole run. The swell is there, the energy is there, and the wind is just about manageable. For an expert surfer, that's your window. Otherwise, it's a long wait for the wind to play ball.
Rusty out.

Information about the Tandjung-Lefts Surf forecast
The above surf forecast table for Tandjung-Lefts provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tandjung-Lefts can be found by selecting the local surf guide option on the grey menu. Our Tandjung-Lefts 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 (Tandjung-Lefts) 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 Tandjung-Lefts 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.
Tandjung-Lefts is 7 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.
