The Lowdown
Alright folks, Rusty here. Let's have a look at what this stretch has in store for us. It's a solid run of clean, consistent south-west swell at Halfway, but we've got a bit of a slow start before the magic kicks in.
Overall, we're looking at a long, drawn-out pulse of groundswell from the south-west. The first recommended surf doesn't show up until the afternoon of Tuesday the 15th. There's a bit of a gap there at the beginning, so don't bother paddling out until then. The water temp is sitting at a warm 80° F, which is pretty much dead average for this time of year, so no surprises there.
Tuesday the 15th afternoon delivers a clean 6 ft SW swell with a proper 15 second period. This is a solid groundswell with moderate energy (1349), and those cross-off winds from the SE will keep the faces tidy. Not a standout yet, but a good sign of things to come.
The real pick of the first week is on Sunday the 20th. The afternoon session is a clear winner. We get a 7 ft SW swell, with a nice 16 second period – that's a long-period groundswell pushing strong wave energy (2120). Winds are a gentle breeze from the SE, keeping things cross-off and clean. This is excellent for experienced surfers, but at 7 ft, it's pushing the upper limit, so it's not the day for a learner. This is the best on offer for the early part of the forecast.
Moving into the next week, Monday the 21st morning is a ripper. We're looking at a 6 ft SW swell, with a 14 second period and a proper offshore wind from the ESE. Gentle breeze, glassy, clean – that's as good as it gets for conditions. It's a bit smaller than Sunday but with that offshore wind, the quality will be hard to beat.
Now, hang on to your boards. The absolute standout of the whole 16-day window, the one you circle on the calendar, is Saturday the 26th of September afternoon. We've got a 7 ft SSW swell cranking with a massive 19 second period – that's a very long-period, high-energy swell. The combined energy is an enormous 4502, which is strong. Winds are gentle from the SE keeping it cross-off and clean. This is excellent, powerful surf for experienced guys. It's a serious swell, so only paddling out if you know what you're doing.
The day after, Sunday the 27th, the swell jumps to a whopping 10 ft. That's expert-only territory. The energy is massive (5428), but even the forecast says it's likely too big for this break. If you're an elite charger, maybe, but for everyone else, give it a miss.
Monday the 28th afternoon settles back to a much more manageable 7 ft SSW swell, still with a 16 second period and good energy (2200), making for another excellent session for the experienced crew.
So, to call it: The best windows are the afternoon of Sunday the 20th of September for that first big push, and Monday the 21st morning for the offshore glass. But the true headliner, the one to build a session around, is Saturday the 26th of September afternoon for that massive, long-period groundswell.
Remember, Halfway can get a crowd "sometimes", so expect a few fellow surfers out there for the standout sessions.
Stay safe, keep your eyes on the horizon.
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.
