The Lowdown
Alright crew, Rusty here, breaking down the swell window ahead.
We’ve got a long run of waves coming, but you gotta be patient on the front end. The first few days are building, but with cross-off wind you’ll be fighting a bit of chop. The real highlight is about a week out, Thursday, August 20th. That’s when it all comes together.
Water temp at Halfway is spot on for this time of year, 79°, so nothing out of the ordinary.
Halfway is the only break showing, and it’s fairly consistent, which is a good sign. Starting Monday the 17th, we’ve got a 5ft SSW swell with moderate energy (893). It’s clean but not great – you’ll find a wave, but it’s a workout. Tuesday the 18th, the energy jumps big time with a 6ft SSW swell and strong energy (2883), and a 16-second period. That’s real groundswell, which packs a punch but can wall up at a beach break. Still, it’s clean.
Wednesday the 19th brings a 8ft swell from the SSW with an 18-second period and very strong energy (3575). That’s getting chunky, and the cross-off wind keeps it from being smooth.
Thursday morning, August 20th, is the real standout of the first week. The swell is 8ft from the SW, 16-second period, with very strong energy (3695). The wind drops to a gentle breeze (15 km/h) out of the ESE, cross-off. They’re calling it excellent for experienced surfers. That’s the day. Crowds are "sometimes", so you might have a few buddies out, but it won’t be packed.
After that, the swell settles but stays in the 5ft to 8ft range through the rest of the week and into the next. The wind stays cross-off, so it’s always rideable, but not epic.
Into the second week, the pattern holds. There’s a bit of a lull around Wednesday, August 26th, with the swell dropping to 5ft and energy weakening (926). But it fires back up on Saturday, August 29th – light breeze (15 km/h), clean 6ft swell from the SSW, and another "excellent for experienced" call. It’s a good session, but not the top dog.
Towards the end, Monday, August 31st is interesting. A 5ft swell with a very long 21-second period and strong energy (3469) in the morning, building to 7ft with a 19-second period and very strong energy (4218) in the afternoon. Light cross-off wind again. That long period at a beach break will make it fast and maybe a bit straight, but the long lulls will make paddling out a breeze.
Bottom line: Thursday, August 20th is the one to aim for – big, clean, and powerful. Saturday, August 29th is a solid backup with lighter wind. The rest is fun, but not gonna blow your mind.
Stay salty.
Rusty.

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.
