The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of groundswell on the way for Mawi, a challenging reef break that’s exposed to the SW. This isn’t for the faint of heart. The water temp is sitting at 80°, which is spot on for this time of year, so no surprises there.
The first real action kicks off Monday, August 3rd. The morning session is looking clean, with a 6ft SSW groundswell at a long 15 seconds. The wind is a cross-off from the SE, which should keep things tidy. The combined energy is strong at 1546, so there’s plenty of push. This is excellent, but only for experienced surfers. The afternoon sees the wind pick up a bit, making it more marginal.
Tuesday, August 4th, the swell drops slightly to 5ft in the morning, but the period stretches to 16 seconds. The afternoon is the pick of the day, with a 6ft SSW swell, lighter 6 mph winds, and a score that reflects the cleaner conditions. The tide might be a factor, so keep an eye on that.
The swell builds through the week, but so does the wind. Wednesday and Thursday see the swell holding around 6ft to 7ft, but the wind is consistently in the 12-19 mph range, which makes it a bit of a battle. Thursday morning hits 7ft at 17 seconds, but with a 19 mph cross-off, it’s going to be textural and challenging.
The standout window is shaping up for Friday, August 7th, through to the weekend. Friday morning delivers a 8ft SSHW swell at 17 seconds, with a gentle 9 mph breeze. The energy is very strong at 3274. This is the best of the first week, but at 8ft, it’s getting into expert-only territory. Saturday stays solid around 8ft, but the wind ramps up again, making it less appealing.
Sunday, August 9th, is a write-off for quality surfing. The wind is up to 19 mph, and the swell is still big, but the conditions are going to be messy.
For the second week, we’ve got a couple of real potential standouts. Monday, August 10th, the afternoon shows a 10ft SSW swell at 18 seconds, with a combined energy of 4931. That is a serious amount of water moving. The wind is a moderate 12 mph, so it’s still on the edge. The real gem is Thursday, August 13th. The morning has a 10ft SSW swell at 18 seconds, with a gentle 9 mph breeze, and the energy is 5600. The afternoon is even better, with the wind dropping to 6 mph. The data flags this as exceptional for experts. This is the one to circle, but it’s a long way out, so don’t book the time off just yet.
The last few days, from August 15th onward, get blown out. The wind is howling at 22-25 mph, and the swell drops. The sea state will be a mess, and honestly, this setup looks more interesting for kite surfing than paddle surfing.
The standout of the whole period is the morning of Thursday, August 13th. That 10ft, 18-second groundswell with light winds at Mawi will be a rare, powerful beast. Think of it as a reward for the patient, expert surfer. But remember, crowds are possible here, so get in early.
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.
