The Lowdown
Alright, Rusty here. Let's talk about what's on the menu at Mawi.
Alright, the outlook for the next sixteen days is a bit of a mixed bag. We've got a solid, consistent run of south-west groundswell, but the wind is a persistent cross-offshore, mostly from the south-east. It’s not terrible by any means, but it’s not glassy perfection. The water’s sitting at a warm 80°F, which is bang on normal for this time of year, so that's no surprise.
We kick things off on Tuesday, the 1st of September, with a clean, clear morning. Swell is a solid 7ft out of the south-west with a very long period of 18 seconds, packing a punch. That’s a powerful, proper groundswell. This reef is for the advanced crew only, and with the swell over 5ft, beginners should stay out of the water. The wind is a fresh 19 mph from the east-south-east, making for a cross-off situation. The break handles it, but it’s not the best it could be. This pattern holds for the first week through Tuesday, 8th September. The swell size bounces around between 5ft and 8ft. The standout in the first week is definitely the afternoon of Tuesday the 8th. We see the swell bump to 10ft from the south-south-west with a period of 18 seconds. That is big and powerful. For experts only. It's a hell of a lot of water moving around.
The story through the second week, from the 9th onwards, is more of the same, but the swell gradually backs off. We get a nice pulse on Tuesday the 15th with a 7ft south-south-west swell. The morning of Wednesday the 16th is the best of the late run. We get a nice 7ft south-south-west swell with a 15-second period, the wind eases to a gentle 9 mph from the south-east, and the conditions are noted as excellent for experienced surfers. That is your call for the second week. The rest of that week is a steady diet of clean but building wind and similar sized swell, nothing that special. Over the entire forecast, the wind never goes offshore enough to make it truly glassy, but it stays cross-off and manageable.
All in all, Mawi is the only game in town, and it offers a solid, long period south-west swell window. The biggest, most powerful days (8th of September) are for experts only. The more moderate, cleaner conditions on Wednesday the 16th look the best for the average advanced surfer.

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.
