The Lowdown
Alright folks, Rusty here. Let's get into it. We've got a solid run of surf on the cards for Halfway, stretching right through the next couple of weeks. The water’s sitting at 79.9°, which is pretty much bang on average for this time of year, so no surprises there.
The pattern kicks off Wednesday morning with a solid pulse of SSW groundswell. We're looking at a 8.2 ft swell with a very long 16-second period, and the combined energy is strong at 3182. That's a lot of water moving. The wind is a cross-off from the SE at 12 mph, which will keep things clean. You'll want to be an experienced surfer for this one, as it's big and powerful. The long period will make it a bit walled-up at a beach break, but the power is undeniable. Thursday morning eases slightly to 6.9 ft, still with that long period, and the wind drops to 9 mph – that's a recipe for some excellent, clean waves for the experienced crew.
The swell settles into a nice rhythm through the end of the first week, hovering around 4.9 ft to 6.2 ft, with cross-off winds keeping the surface clean. The energy is still moderate to strong, with readings between 1285 and 2512. It's not firing on all cylinders, but it's a reliable, surfable run.
The standout window, and the one that really gets the blood pumping, is around the 22nd and 23rd of September. We’ve got a pulse of SSW swell that pushes back up to 8.2 ft, with a long period of 18 seconds. The combined energy on Tuesday the 22nd morning is a massive 5409 – that’s strong to very strong energy, and it’s a long-range forecast, so keep an eye on it. The winds are light to moderate and cross-off, so conditions will be clean. This is a big, powerful groundswell that will only be for the experts given the size and the long period, but the potential is massive. The 23rd hangs on with 7.2 ft and excellent conditions for experienced surfers.
Overall, we've got surf almost every day, but the 22nd and 23rd of September are the ones to circle on the calendar. Crowds are a possibility, as it's a fairly consistent spot, so get in early.

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.
