The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way for the next couple of weeks. First up, we have Mawi, a solid reef break that only the advanced crew should be sizing up. The water temp is sitting at a pretty average 80°, so nothing unusual there for this time of year.
The good news is there’s surf on the table right from Friday the 28th of August. It kicks off with a solid 10ft SW groundswell at 16 seconds – that’s some serious long-period energy (combined energy at 4214). It’s a big one, too big for beginners, and honestly, it’s in that expert-only territory at over 8ft. The wind is a cross-off from the SE at 9 mph, which will keep things reasonably clean, but the call says it’s a bit marginal with the tide. Saturday the 29th drops to a still-chunky 7ft from the SW at 15 seconds (combined energy 1768), with the same clean cross-off breeze. That Saturday morning is the standout of this first wave – excellent conditions for experienced surfers, and the swell is big but not out of control.
Sunday the 30th backs off a touch to 5ft SW at 13 seconds, still clean but the energy is dropping (1169). Then we hit a bit of a lull through the start of the week. Monday and Tuesday see the swell come back up around 7ft, but the wind picks up to a fresh 16-19 mph – still cross-off, but it’s gonna be bumpy. The energy is moderate (2871 on Tuesday morning), but the surf is just marginal. This stretch from Sunday the 30th through to Thursday the 3rd of September is a bit of a write-off for quality, with only 5ft to 6ft on offer and those stronger winds.
There’s a small window of cleaner but smaller surf around Friday the 4th and Saturday the 5th, with 4ft to 6ft SSW and lighter winds (16 mph), but the energy is weak (767 to 1095). Not worth getting too excited about. We then get another pulse of SSW swell from Sunday the 6th into Monday the 7th, with 6ft to 7ft at 14-16 seconds (energy climbing to 2729). Still, it’s marginal.
Now, the real highlight arrives later in the second week. Mark Friday the 11th of September on your calendar. The afternoon shows a 12ft SSW groundswell at a very long 18 seconds – that’s proper, deep ocean energy (combined energy 8623). This is a standout, but it’s well over 8ft so experts only. The wind is a clean cross-off from the SSE at 12 mph. It’s a reef break, so that long-period swell will set up beautifully, but be aware at a beach setup it can fold over too straight. Here, it’s gonna be pumping. Saturday the 12th holds at 12ft in the morning and 10ft in the afternoon, still from the SSW at 17 seconds (energy 6680). Crowds are possible at Mawi, so get in early if you’re keen.
Overall, the best bet is Saturday the 29th of August for a solid, manageable size, and then Friday the 11th of September afternoon for the big, powerful groundswell. The first week has a few gaps of small, windy days, but home base is looking alright.
Rusty.

Information about the Mawi Surf forecast
The above surf forecast table for Mawi provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mawi can be found by selecting the local surf guide option on the grey menu. Our Mawi 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 (Mawi) 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 Mawi 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.
Mawi is 25 km (16 miles) from the city of Praya. If you plan a holiday in South Coast of Lombok, look for hotels and other accommodation in Praya. Praya has rooms for a wide range of budgets as well as car hire and transport links.
