The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking at Halfway.
Overall, we’ve got a solid run of SW groundswell lining up for the next couple of weeks. The water is sitting at a warm 80°, which is right on the money for this time of year – no surprises there. You’ll be in boardshorts or a light springy.
This stretch kicks off Saturday the 12th with a clean 5 ft SW swell pushing in from a solid 14-second period. It’s got a nice bit of energy behind it (1727) and the wind is cross-off from the SE, keeping things tidy. It’s not the biggest, but it’s a nice and easy start for an intermediate. The crowds can show up here sometimes, so keep that in mind.
Sunday the 13th sees a bump up to 6 ft in the morning with a long 18-second period, pushing the energy way up (2512). It's going to have proper push and shape, that groundswell. It builds to 7 ft by the afternoon, still with a very healthy 17-second period and 2625 energy. The wind stays cross-off, so expect clean surf, but with that period, the sets might be a bit more spread out.
Monday and Tuesday hold fairly steady in the 5 ft to 6 ft range, periods dropping back to 15-16 seconds. Energy stays moderate to strong. Still clean, still consistent.
Wednesday the 16th through to Thursday the 17th, it holds around 6 ft to 6 ft, shifting a touch more SSW. Periods around 14-15 seconds. The wind keeps that clean cross-off feel. Surfable, but nothing huge.
Friday the 18th is a bit of a down day. Swell drops to 5 ft in the morning and down to 3 ft by the afternoon. Energy drops off noticeably. Still clean, but weaker.
Now here’s where it gets interesting. Saturday the 19th is a proper standout. The swell is still a modest 4 ft, but the conditions are dialled – clear skies, gentle cross-off breeze, and the water is glassy. The wave period is 14 seconds, the energy is back up (1009-1046), and the commentary says it’s excellent for experienced surfers. This is the kind of day where every wave feels like it’s built just for you. Don't sleep on it.
Sunday the 20th swings back up to 7-7 ft, with a 16-second period and strong energy (1999-2175). The wind stays mellow, so the afternoon session could be a real highlight again.
Through the next week, it stays in the 6 ft to 7 ft range, with the odd spike. It’s consistent, and the cross-off wind stays your friend.
Now, keep your eyes peeled on Wednesday the 23rd. We’ve got a 7 ft SSW swell in the morning with a 16-second period and a massive 3470 energy. By the afternoon it’s 8 ft, 17 seconds, and 3336 energy. That’s serious power. It’s going to be clean, but 8 ft is expert territory.
And then we hit Friday the 25th. The morning shows a clean 6 ft swell, but the period jumps to 20 seconds – very long groundswell – and the energy is 3915. By the afternoon, it ramps to 10 ft, 19-second period, and an enormous 7490 energy. That is a proper pulse. The word is that it’s too big for this break. That’s a hard pass for the average punter. Even Saturday the 26th morning is 10 ft and still too big. The afternoon settles to 8 ft with 17-second period and 4031 energy. If you’re a well-seasoned charger and you can handle the size and the crowds, that Sunday the 27th morning with 7 ft and 16-second period is another excellent option.
For the standout, I’m calling Saturday the 19th. That 4 ft with glassy conditions and that excellent rating is the pick of the run for a relaxed, quality session. For the bigger-wave crew, Saturday the 26th afternoon is the one to target – just know your limits.
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.
