The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
We’ve got a solid run of swell coming into Mawi, a reef break that’s exposed to the southwest. It’s an advanced wave, takes a bit of knowledge to handle, but it’s fairly consistent. The water temperature is sitting at 80°, which is about average for this time of year, so nothing unusual there.
The first few days are a bit of a tease. Wednesday the 29th and Thursday the 30th, we’ve got clean, cross-off conditions from the SE, but the swell is only around 4 ft to 5 ft from the SSW. The energy is moderate, with readings around 900 to 1300 (combined energy of all swells directed here), but the forecast is calling it marginal. The period is a solid 14 to 15 seconds, so there’s some groundswell grunt, but the quality isn’t quite unlocking yet.
Friday the 31st, the period jumps to 17 seconds, still 4 ft to 5 ft, and the winds ease off to a moderate breeze. The energy climbs to 1600 to 1756. It’s getting better, but still not quite the standout.
Now, Saturday the 1st of August is where things start to turn. The swell picks up to 5 ft in the morning, then 6 ft in the afternoon, with a 16 to 17-second period. The wind drops to a gentle breeze, cross-off, and the energy jumps to 1882. The afternoon session is flagged as excellent for experienced surfers. This is the first real highlight of the run.
Sunday the 2nd of August is the peak of the first good pulse. Swell hits 7 ft from the SSW, period at 16 seconds, winds light and cross-off, and the energy is roaring at 2250 to 2368. This is proper, clean, powerful reef swell. For the advanced crew, this is the best on offer in the first week. The wave is going to be solid, so keep your wits about you.
The energy drops slightly into Monday the 3rd and Tuesday the 4th, with 6 ft to 6 ft, still excellent conditions, but the period drops back to 14 to 15 seconds. It’s still good, but the magic of Sunday is the real standout.
Wednesday the 5th into Thursday the 6th, the wind picks up to a fresh breeze, and the swell builds again. By Thursday the 6th, we’re looking at 8 ft with a 17-second period, and the energy is over 3000. It’s big, powerful, and cross-off, but the wind is moderate to fresh, so it’s not as clean as the weekend.
Then, Friday the 7th of August. This is a big one. Swell hits 8 ft in the morning, then 10 ft in the afternoon, with a 17 to 18-second period. The energy is massive – 5735 to 6157. That’s a lot of power. The wind is a fresh cross-off. This is a serious, heavy swell. For experts only – this is the standout of the whole period. It’s a promise from the long-range, so keep an eye on it, but it looks like a beast.
The following days, from the 8th to the 13th, we see a slow decline, but it remains solid. Swells hold between 7 ft and 8 ft, with periods of 14 to 18 seconds, and moderate cross-off winds. The energy stays in the 2300 to 4200 range. There’s a nice pulse on the 11th with a 20-second period, but it’s not quite as clean as Friday the 7th. The 12th and 13th stay big, but the wind is a bit stronger, so it’s less perfect.
So, to wrap it up: the best on offer is Sunday the 2nd of August for a clean, powerful session, and the absolute standout is Friday the 7th of August for the big, heavy, expert-level swell. The rest of the window is filled with solid, consistent surf, but those two are the gems.
Stay safe out there.
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.
