The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid stretch of surf on the horizon at Halfway. This is an exposed, fairly consistent intermediate spot that loves a good SW groundswell, and we’re looking at a serious run of energy. The water temp is sitting at 79°, which is bang on average for this time of year, so no surprises there. The standout period is right at the start.
Tuesday morning, the 18th of August, is the real pick. We’ve got a clean 6 ft SSW swell pumping in with a very long 16 second period – that’s proper groundswell energy. The combined energy is a strong 2883, and with a light cross-off ESE breeze at 9 mph, the surface is going to be glassy. This is excellent surf for experienced surfers, but at this size, it’s a bit much for beginners. The offshore wind is a major plus, keeping things clean. Crowds are a possibility, so get in early.
The size builds through Wednesday and Thursday, hitting 8 ft of SSW swell, but the wind picks up to 16 mph, staying cross-off. The energy is impressive, hitting 4037 on Wednesday afternoon, but the bumpier conditions make it less of a perfect picture than Tuesday morning. Still, for the experienced crew, there’s plenty of power. This size is definitely in the expert zone.
There’s a gap in the quality after the first week. By the 22nd of August, the quality drops. The wind stays fresh, and the swell stays around 7 ft, but the scores tell the story – it’s just marginal. The energy drops off too, down to 1762 by the 23rd. The 26th sees the swell drop to 6 ft with a period of 14 seconds, and the energy falls to 1099. It’s still surfable, but nothing to write home about.
Then we get a second pulse. The 29th of August Saturday morning offers a clean 5 ft SW swell with a 14 second period and a light 6 mph SSE breeze. The energy is 1140, and the conditions are marked as excellent. This is a hidden gem in the forecast, but the swell is a bit smaller.
The real second standout is the 31st of August Monday morning. We’re back to 7 ft of SW swell with a 16 second period, a light 9 mph SSE cross-off breeze, and a combined energy of 2056. Excellent conditions for experienced surfers again. And then it builds into September, with the 1st of September Tuesday afternoon hitting 8 ft of SW swell, a 16 second period, and a massive energy of 3254. That’s a serious, powerful groundswell with clean conditions. The 2nd of September Wednesday morning holds 8 ft of SW swell with a 16 second period and an energy of 2494 – also excellent. This is a long-range standout, promising but a few weeks out, so keep an eye on it.
So, the best on offer is the Tuesday morning, 18th of August, with the clean, powerful SSW groundswell. The second standout is the Monday morning, 31st of August, with another clean, solid groundswell.
Rusty out.

Information about the Halfway Surf forecast
The above surf forecast table for Halfway provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Halfway can be found by selecting the local surf guide option on the grey menu. Our Halfway 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 (Halfway) 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 Halfway 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.
Halfway is 2 km (1 miles) from the city of Kuta. If you plan a holiday in Kuta - 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.
