The Lowdown
Alright, this is Rusty, and I’m lookin’ at the Mawi forecast for the next couple of weeks. Let’s get into it.
The good news is, there’s solid swell on the horizon, but it takes a minute to get going. The early part of the window is a bit of a slow burn. The first few days, Thursday the 30th and Friday the 31st of July, are a bit of a tease. We’ve got clean, cross-off winds from the southeast, but the wave quality is just not there. It’s a bit sloppy under the hood. The water temp is a warm 80°F, and that’s bang on average for this time of year, so no surprises there.
The first real sign of life comes on Saturday, the 1st of August. The morning shows a clean 5ft SSW swell with a 16-second period, and the wind drops to a light 9 mph cross-off. The afternoon gets even better: 6ft from the SSW, a long 17-second period, and the wind eases to just 6 mph. This is when Mawi starts to wake up. The water is glassy, and the conditions are clean. This is the standout for the first week, especially for the experienced crew. The swell is getting up there, but it’s not out of control.
Sunday the 2nd pushes it further. The swell hits 7ft with a 16-second period, and the energy is climbing. Still clean, still cross-off winds. This is proper Mawi form. The crowd is a concern here, though, as it can get busy, so bring your patience.
Monday the 3rd holds at 6ft but the period drops a touch, and the afternoon gets a bit windier. From Tuesday the 4th through to the 10th, the swell stays solid, mostly between 5ft and 8ft, but the wind picks up, blowing 15 to 19 mph at times. The energy is massive, but with that wind, it’s going to be a bit of a battle. It’s still clean, but the cross-off wind gets fresh, and the quality takes a hit. The 9th of August is a standout for raw power, with a 8ft SSW swell at 17 seconds, but it’s more of a grind than a glide.
Now, the real standout for the whole outlook is Tuesday the 11th of August. The morning has a 7ft SSW swell, but the wind goes light and variable from the SSE at just 6 mph. That’s the call. Then the afternoon goes off: 10ft of SSW swell with an 18-second period, and the energy is a massive 5221. That’s serious groundswell. The wind is a gentle cross-shore, so it’s not perfect, but for size and power, this is the day. At 10ft, this is expert territory only. The long period means it’ll be grinding, and at a reef like Mawi, that’s a thing of beauty.
The 12th holds strong at 8ft, but the wind swings more southerly and picks up. The 14th of August sees another spike, with a 6ft swell, a 17-second period, and energy hitting 5055, but the wind is up to 19 mph and there’s rain showers, so it’s a wild card.
Bottom line: The first few days are a write-off. The real action starts Saturday the 1st of August, builds through Sunday, and peaks on Tuesday the 11th. If you’re an experienced surfer, that Tuesday afternoon is the one to circle. The 9th is also a huge swell day, but windy. For the rest of us, the Saturday morning and Sunday are your best bets for fun, clean waves in the 5ft to 7ft range.

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.
