The Lowdown
Alright folks, Rusty here. Let’s get into it.
So, we’ve got a pretty persistent run of surf on the cards at Halfway. The whole 16-day window is active, no quiet start – just a long stretch of clean, cross-off conditions from the southeast and east-southeast. That wind direction means the lines will be tidied up nicely, so the surface should be smooth most mornings. The water temperature is sitting at 80°, which is a smidge cooler than average for this time of year, but nothing wild – just about normal.
The swell is coming from the SSW for the most part, which lines up well with what this break likes. We start off on Wednesday the 16th with chest-high sets around 6ft, with a solid 15-second period that’ll push plenty of energy your way – combined energy hitting 1181 (moderate). That south groundswell will wrap in with some proper shape, and with glassy mornings before the breeze picks up, it’ll be a good, clean session. The energy builds through Thursday the 17th, with 7ft swell and even more grunt (1762 combined energy). That’s getting solid but still manageable for intermediates.
Friday the 18th might be the first real standout. Swell drops back a touch to 5ft, but the period stays long at 14 seconds, and the wind goes offshore in the afternoon – straight out of the ESE at 12 mph. That’s clean, lined-up surf with a bit of push, and combined energy around 904. This is where you want to be.
Saturday the 19th fades a bit – wave height dips to 4ft, still rideable but not as punchy. Then we get a fresh push on Sunday the 20th: 7ft swell from the SW with a 16-second period, combined energy 2067 – that’s moderate energy but with a heap of quality. The wind stays cross-off, so expect some clean, solid walls. This is another standout window right through the day.
The pattern holds through the start of the following week with chest-to-head-high surf, all clean. Then on Wednesday the 23rd, we see the swell bump up again: 7ft from the SSW, period at 16 seconds, combined energy of 2359. That’s a serious pulse. The wind holds offshore for the afternoon at 12 mph, so it’ll be a ripper for experienced surfers.
Now, keep an eye on Saturday the 26th. That afternoon we’ve got 10ft of swell with a 20-second period – combined energy is 6091 (strong wave energy). That is big, powerful groundswell, and the period is very long. That kind of energy will make for some proper freight-train walls at Halfway, but it’s not for anyone who isn’t confident in solid surf. It’s expert territory. The same runs into Sunday the 27th, still 10ft and very long period. By Monday the 28th it drops to 8ft, still with excellent conditions for experienced crew.
After that, we wind down through the 29th and 30th with surf easing back to 5ft–6ft, still clean and rideable. The last days on the 1st of October see the swell dip under 3ft but the period stays long – still surfable on a bigger board.
One thing: the swell direction is mostly SSW and SW, which is optimal for Halfway, and the wind stays cross-off or offshore nearly the whole time. Crowds can be an issue here at times – it gets busy, so plan for an early paddle if you want the best of it.
Overall, the standout days are Friday the 18th for that clean offshore afternoon, and the whole Sunday the 20th through Wednesday the 23rd window for solid, quality swell with good wind. If you’re up for a challenge, that big pulse on the weekend of the 26th and 27th will be serious.
Keep it 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.
