The Lowdown
Alright folks, Rusty here. Let's get into it.
We’ve got a steady pulse of SW swell lining up for Mawi for the whole sixteen days, but it’s a mixed bag in terms of quality. The water temp is 26°, basically spot on average for this time of year, so nothing weird going on there.
The first few days, from Thursday the 6th through to the 9th, we're looking at solid 7ft to 8ft of SW swell, but the wind is a persistent cross-off from the ESE to SE at 15-16 mph. It keeps things clean, but the marginal surf forecast comments tell you it’s not the best. The combined energy sits between 2285 and 3757, which is moderate, but the quality just isn't there.
Monday the 10th starts to wake things up. Monday afternoon sees the swell jump to 10ft from the SSW with a 18-second period. That's some serious energy (6706) and a proper groundswell. The wind is a cross-off from the SSE at 12 mph, and the score jumps to a 6. This is an advanced-only wave at that size. The very long period (18 secs) will make it bend around the reef perfectly at Mawi, but expect longer waits between sets.
The real standout window is Tuesday the 11th. Tuesday afternoon delivers a 10ft SSW swell with a 19-second period and a combined energy of 8739. The wind is a clean cross-off from the SSE at 12 mph. This is the best call of the whole outlook. It’s big, it’s lined up, and the direction is exactly where Mawi likes it (SW optimum). This is a day for the experienced crew only – that size is expert territory. You might have some company though, as crowds are listed as “sometimes.”
Wednesday the 12th through to the 20th sees the swell bouncing around between 5ft and 10ft, but the wind stays consistent from the SE. The overall quality is rated as marginal or just okay, with scores mostly in the 2-5 range. Nothing to get too excited about there.
Then, for the second week, look out for Friday the 21st. The morning shows an 12ft SSW swell with an 18-second period and a very strong 7426 of energy. Wind is a gentle 9 mph from the SE. That’s another big, powerful swell. It’s promising but it’s a long way out, so keep your fingers crossed. The direction is bang on, it’s just a case of whether the wind gods play nice.
So, the best on offer? Without a doubt, Tuesday the 11th. The Tuesday afternoon session has the biggest energy numbers and a perfect swell direction for Mawi. The second best is Friday the 21st, a promising late call with serious size. Everything else is just okay – clean enough, but not the quality you want for a standout session. It’s all for experts when it’s over 8ft, and there’s a lot of that around.

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.
