The Lowdown
Alright, let’s break it down in feet and miles per hour. The only break in the game is Mawi, a reef that loves a SSW to SW angle. Water temp is pretty standard for this time of year. The whole forecast has “marginal” on every session, but that doesn’t mean it’s flat. There’s a bit of a wait for the real standouts, but the surf runs fairly consistent.
Starting August 22: Saturday morning sees a 8ft SSW swell with a 16-second period, combined wave energy at 2731 – that’s serious power. Wind is a 15 mph SE cross-off, so clean but big. This is advanced only; over 8ft is expert territory. Saturday afternoon and Sunday hold 7ft to 7ft, similar period, energy still in the thousands. Monday August 24 eases to 7ft.
The big standout is Friday August 28. Morning: 8ft SSW swell, 16 seconds, energy at a huge 3881. The strongest energy of the whole run. Wind is a moderate cross-off at 15 mph, clean but heavy. Afternoon is 8ft SW. This is for experts only.
Tuesday September 1 is the next standout: afternoon delivers 7ft SW swell, a very long 19-second period, energy at 3706. That’s a proper groundswell, perfect for Mawi’s reef. Wednesday September 2 keeps up with 8ft SW, 17 seconds. These two days in early September are your best bet for quality, though they are a bit further out.
Crowds are “sometimes” so you won’t have it to yourself, but it won’t be a madhouse.
For the best of the best, hit Friday August 28 for raw power and Tuesday September 1 for that long-period perfection. The rest is clean but not as memorable.

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.
