The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the cards for the next couple of weeks.
Overall, we’ve got a solid run of swell at Halfway. It’s a fairly consistent stretch, with building energy through the first week and a real standout push towards the end of the forecast period. The water’s sitting at a warm 80° right now, which is dead average for this time of year, so no surprises there.
The action kicks off on Tuesday morning, the 8th of September. We’re looking at a 7 ft SSW swell with a 13-second period, and the combined energy is a strong 2916. The wind is a cross-off from the SE at 12 mph, which keeps things clean, but the conditions are a bit marginal. The swell drops to 6 ft in the afternoon, but the period jumps to 18 seconds, so it’s a proper groundswell, with strong energy at 3469. That longer period will make for some nice lines, but it’s a day for the experienced crew.
Wednesday the 9th is the real highlight of the first week. The morning brings an 8 ft SSW swell, 16-second period, and a combined energy of 3182. The wind is a gentle 9 mph cross-off from the SSE. This is proper surf – solid, clean, and with plenty of punch. The afternoon stays excellent with a 8 ft swell and energy of 2823. This is a day for confident intermediate and advanced surfers; it’s too big for beginners.
Thursday through to the following Monday, the 10th to the 14th, holds a steady run of 5 ft to 7 ft SSW/SW swell, mostly with 15-18 second periods. The combined energy remains moderate to strong, in the 1358 to 2561 range. The wind stays cross-off from the SE or ESE, 12-16 mph. It’s consistent, clean, and surfable every day, but honestly, nothing jumps out as a standout. The crowds here are sometimes an issue, so keep that in mind.
Now, the real standout is shaping up for late in the window. On Wednesday the 23rd of September, we’ve got a 7 ft SSW swell, 16-second period, and a massive combined energy of 4060 in the morning. The wind is a light 9 mph cross-off from the ESE. The afternoon is even more impressive with a 6 ft, 19-second period groundswell and energy of 4033. That’s a lot of power and a very long period, which will make for some properly lined-up waves. This is a day for the experts only – anything over 8 ft is for the experienced crew, and this one’s got the grunt to back it up. It’s a long way out, so keep an eye on it, but it’s the one to circle on the calendar.
Tuesday the 22nd of September is also worth a mention: a 5 ft, 21-second period swell in the afternoon, with energy of 2565. That’s an incredibly long period, so the waves will be fat and powerful, but it’s best suited to a point or reef break setup.
Overall, there’s no real gap in the surf here. It’s a consistent 16-day run. The best of the best is that Wednesday the 23rd, and Wednesday the 9th is the solid early shout. Stay safe out there.
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.
