The Lowdown
G’day, I’m Rusty. Let’s talk about what’s cooking at Halfway. We’ve got a strong, drawn-out run of SSW groundswell coming through, holding at decent size for a good stretch. The winds are all cross-offshore, so the face will be clean for the most part, but the energy levels are huge – we’re talking a solid pulse of wave energy with combined values in the high thousands (3965 to 4103), meaning this is very strong stuff. Water temp’s sitting at 79°F, bang on average for this time of year.
The best of it kicks off on Thursday 13th afternoon. That’s the standout: swell hits 10ft from the SSW with a 16-second period, and the wind is a clean cross-off at 12 mph. The combined energy is a whopping 4103 – that’s serious power. It’s going to be too big for beginners at this size, but for experienced surfers, the setup is dialled. Crowds can pop up here sometimes, so keep an eye out.
On Friday 14th, the swell backs off a touch to 7-7ft, still from the SSW, but the energy is still strong (2267-2956). Winds stay cross-off. It’s clean but the wave comment flags marginal conditions – probably more about tide or shape. Still worth a look for the experienced crew.
Saturday 15th and Sunday 16th are the real gems of the first week. The swell holds at 7ft on Saturday with a long 17-second period, cross-off breeze at 9 mph, and the energy is still in the strong range (2929). Sunday drops slightly to 6ft, but the winds are light and cross-off. The comments call it “excellent surf conditions for experienced surfers” – that’s the sweet spot. For a spot that’s fairly consistent and exposed to SW swell, this is the pick of the window if you want cleaner, more manageable size.
Monday 17th sees a drop below 5ft, energy dips under 1100 – it’s weaker and only marginal. The trend then rebuilds. Wednesday 19th sees another solid push: 8-8ft from SSW with an 18-second period, combined energy jumping to 3568-4083. That’s a strong pulse, but winds are up to 12 mph cross-off – still clean, but the wave comment says marginal. Standout alert: Thursday 20th morning is a real spike – 10ft SSW with 16-second period, energy at 4071, and the comment explicitly says “wind and tide favorable, but the swell is predicted to be too big for this break.” That means it’s expert-only, and the crowd factor could spike if it’s really on.
From Friday 21st onward, we’re riding the tail of the swell. The size bounces between 5ft and 8ft through to the end of the month, with the period mostly 14-16 seconds. Winds stay cross-off, usually 12-15 mph. The energy gradually fades into the 1000-2000 range, so the surf becomes more moderate. Tuesday 25th is a low point with only 5ft and a shorter 13-second period, combined energy under 1021 – weak, but still surfable on a bigger board.
Look ahead to Wednesday 26th afternoon: a quirky one – swell jumps to 7ft from SSW with a very long 17-second period, energy at 2704. That long period makes it better for a point or reef setup if there’s one nearby; at a beach, it might break too straight. Still, it’s one to circle for the second week. Thursday 27th holds at 7-7ft with 16-second period, and then things taper off into the 5-5ft range by Friday 28th, with energy dropping under 1200.
No huge gaps of flatness here – this spot is fairly consistent, and the swell keeps rolling. Just note that the best windows are Thursday 13th afternoon, Saturday 15th, Sunday 16th, Wednesday 19th, and Thursday 20th morning. If you’re not an expert, aim for Saturday or Sunday when it’s still solid but not monstrous.
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.
