The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming down the pipe for Mawi.
The opening of this forecast is pretty quiet. The first few days, from Tuesday the 28th to Thursday the 30th, are a bit of a tease. There’s a clean, long-period SSW groundswell rolling in, and the water is a comfortable 80°, which is bang on average for this time of year. The problem is the wind. It’s a fresh cross-off breeze from the SE, blowing at 22 mph, and it’s just making the ocean look a bit messy. The energy is moderate, but it’s not worth paddling out for the quality you’ll get. You’re better off waiting.
Friday the 31st sees the wind ease a touch to a moderate breeze, and the swell settles into a nice 5 ft from the SSW with a super long period of 17 seconds. That’s proper groundswell energy. The conditions are clean. Still, the score isn’t screaming at me yet. It’s a solid warm-up for the weekend.
Now, Saturday the 1st of August is where things start to get interesting. We’ve got a 5 ft to 6 ft SSW swell, a 16 to 17 second period, and the wind is down to a gentle 9 mph cross-off. This is the first real standout. For a reef break like Mawi, that long period groundswell is perfect. It’s not too big for experienced surfers, but it’s well overhead for the average punter. Crowds are sometimes a thing here, but with these clean, lined-up sets, it’s worth competing for a few waves.
Sunday the 2nd of August is the pick of the first week. The swell bumps up to 7 ft to 7 ft from the SSW with a 16 to 17 second period. The wind is still a gentle cross-off in the morning, making for peaky, clean faces. This is borderline expert territory at that size on a reef, but if you’ve got the skills, it’s going to be one of the best days of the run. The afternoon wind picks up a notch, but the morning session is the one.
The following week, Monday the 3rd through to Wednesday the 5th, is still solid. Swell holds around 6 ft to 6 ft from the SSW, with periods around 14 to 15 seconds. The wind stays in that gentle to moderate cross-off range. It’s consistent, clean, and reliable. Not a world-beater, but a good run of waves.
Now, looking further out, Saturday the 8th of August is a real head-turner. The swell jumps to 8 ft from the SSW, but the period goes absolutely mental at 20 seconds. The wind is a fresh 19 mph cross-off, which is the only thing holding it back from perfection. This is a very long-period groundswell, so it’s going to be heavy, powerful, and a bit more challenging at a reef – but for the experienced crew, this is a serious session. You’ll be waiting for the sets, but they’ll be worth it.
Sunday the 9th of August is the biggest day in the forecast. We’re looking at 12 ft from the SSW with an 18 second period. The wind is a moderate 16 mph cross-off. This is expert-only territory. If you’re not solid on a reef, stay on the beach and watch. It’s a proper big-wave day, and the power is going to be immense.
The final few days, Monday the 10th to Wednesday the 12th, still have plenty of size, with swell between 8 ft and 10 ft, but the wind tends to be a bit stronger. It’s still surfable, but the real magic is in that first weekend and that big pulse around the 8th and 9th.
Best on offer: The standout for me is Sunday the 2nd of August. You get the big 7 ft groundswell, the long 17 second period, and the light cross-off wind in the morning. It’s big, clean, and powerful. The second standout is a long-range call: Sunday the 9th of August. That 12 ft, 18 second swell is a monster, but it’s a promise for the future, not a certainty. Keep your eyes on it.
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.
