The Lowdown
Alright, let’s put that in feet and change things up for you.
First few days at Mawi are rough. You’ve got a lot of SE windswell with short periods, and the wind is blowing cross-off steady from the SE and ESE, so nothing is lining up clean. The first week is mostly a write-off. On Saturday the 25th and Sunday the 26th, you’re looking at 4ft to 8ft of mixed-up, bumpy junk. The water temp is around 80°F, which is totally normal for this time of year. That first Saturday the combined energy is sitting at 1050, which is moderate, but the period is short, so the shape suffers.
Monday the 27th through Tuesday the 28th is poor. I wouldn’t even bother suiting up. There’s a lull in quality until Thursday the 30th, when the swell direction starts to turn more SSW and the period climbs to 15 seconds. The energy jumps to 1266, and you start to feel the groundswell pulse coming through. It’s not perfect yet, but it’s a signal that better days are ahead.
The first true standout is Saturday the 1st of August. That morning you get a 5ft SSW groundswell with a period of 16 seconds and energy at 1727. The wind is still cross-off from the SE at 12 mph, but that’s manageable for this reef. By the afternoon, the swell bumps to 6ft at 18 seconds, and the energy surges to 2423. This is proper surf for advanced surfers only.
Then, Saturday the 8th of August is the big one. The morning forecast is calling for a solid 10ft SSW swell with 17-second period. Combined energy is massive at 5046. That is a heavy, powerful swell. This is only for experienced, strong paddlers who know the reef. The wind will be cross-off from the SE at 12-15 mph, which is okay, but the size and power are the real story here. Crowds are possible when conditions get this good, so get there early if you’re up for it.
The rest of that second week holds consistent 6ft to 8ft SSW groundswell with periods around 14 to 16 seconds, and energy levels in the 1500 to 2500 range. The wind never turns fully offshore, but stays in that workable cross-off zone. Mawi is fairly consistent overall, so even though the start is flat and funky, the outlook turns around in a big way.

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.
