The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of swell on the cards for Mawi. The water temp is sitting at 80°, which is bang on average for this time of year, so nothing wild there.
The first real action kicks off on Sunday morning, the 30th of August. Mawi will be seeing a clean 5 ft SW groundswell with a long 13-second period, pushing moderate energy through the reef (1169). The wind is a gentle cross-off from the SE, so the face will be nice and clean. This is excellent for experienced surfers – the reef setup and the solid period will hold up well. It’s not huge, but it’s a quality start.
Monday the 31st is a step up in energy. The swell holds at 5 ft SW but the period jumps to 18 seconds, making it a very long-period groundswell. The energy kicks up to 1532. The breeze is still cross-off, but it’s blowing a bit harder at 16 mph. Still clean, but with that extra wind. The long period means Mawi’s reef will love it, but expect longer lulls between sets.
Tuesday the 1st of September sees the swell bump up to 7 ft SW, still with a long 18-second period. The energy is really humming now at 2817. The wind picks up to 19 mph from the ESE, still cross-off. This is getting into the more serious stuff – too big for beginners, but for the advanced crew, it’s a fun, powerful wave.
Wednesday the 2nd stays similar, with 7 ft SW and 17-second period, energy at 2495. The wind is still a fresh 19 mph cross-off. The quality is still there, but the wind is starting to push things around a bit.
Thursday the 3rd has the swell easing back to 6 ft SW, period dropping to 16 seconds, energy 1402. The wind drops to 16 mph. Still rideable, but losing that top-end power.
Friday the 4th is a bit of a lull. Swell drops to 5 ft SW, period to 14 seconds, energy down to 810. The wind is still cross-off but the waves are just okay. Not a standout.
Saturday the 5th sees a shift in direction to SSW, with 6 ft and 14-second period, energy 1103. The wind is a moderate 12 mph cross-off. It’s picking up again, but still not the top of the forecast.
Now, for the real standout action. Sunday the 6th of September is where things get spicy. Swell is 7 ft SSW, 15-second period, and the energy jumps to 2936. The wind is a moderate 16 mph cross-off. This is a proper groundswell, and Mawi will be firing.
The absolute best of the entire forecast, though, is Monday the 7th of September. The swell is 8 ft SSW, with a 14-second period, and the energy is 2144. The wind is 16 mph cross-off from the SE. This is a big, powerful day for the reef. Definitely for experts only at this size.
Tuesday the 8th of September afternoon is a major highlight. The swell jumps to 8 ft SSW, with a very long 18-second period, and the energy rockets to 4153. This is a very strong, long-period groundswell. The wind is a moderate 12 mph cross-off. The waves will be big, powerful, and clean. This is the best of the first week.
The second week kicks off with Wednesday the 9th of September, holding 8 ft SSW, 16-second period, energy 3350. Still big and powerful, but the wind is up a bit.
Thursday the 10th drops to 7 ft SSW, 16-second period, energy 2043. Wind is lighter at 9 mph. A nice, cleaner day.
Friday the 11th of September is another massive standout. The swell builds to 8 ft SW, with a 19-second period, and the energy is a massive 4967 in the morning, then peaking at 10 ft SW and 18 seconds in the afternoon with energy at 6368. This is a very strong, very long-period groundswell. The wind is a fresh 19 mph cross-off. This is a beast of a day for the reef. Only for experts.
Saturday the 12th stays big, with 10 ft SW, 17-second period, energy 4448. Still huge, still powerful.
The rest of the period, from Sunday the 13th to Monday the 14th, holds solid 7 ft to 10 ft SW groundswell with periods around 15-17 seconds, energy in the 3000 to 5000 range. The wind stays cross-off. It’s a consistent run of big, powerful surf. The best of the second week is definitely Friday the 11th of September, with those massive energy numbers.
Crowds at Mawi can be an issue sometimes, so with a run this good, expect it to be busy.
Rusty.

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.
