The Lowdown
Alright folks, Rusty here. Let’s break down what’s headed for Mawi.
We’ve got a solid run of south-west groundswell coming through. The water is sitting at about 80°, which is normal for this time of year. The consistency is fairly good, and the conditions are looking clean. The standout period is definitely the second week, with a big pulse that’ll have the experts fired up.
It kicks off Friday morning, August 7th, with a clean 8ft SSW swell at a very long 17 seconds. The wind is a cross-off from the ESE at 12 mph, keeping things tidy. The wave energy is strong. This is quality but advanced-only territory. The afternoon sees similar size and a slightly shorter period of 16 seconds, still very clean.
Saturday the 8th stays similar, with 8ft to 8ft SSW swell, but the wind picks up to 16 mph, making it a bit more textured. Sunday the 9th has the wind cranking up to 19 mph, so while the waves are there, the conditions get a bit lumpy.
Monday the 10th brings a shift. The morning sees a smaller 6ft swell, but with a monster 19-second period, packing a punch. Then the afternoon throws a bigger 10ft SSW swell at 18 seconds. This is a serious amount of water. The wind is a steady cross-off, so it’s clean but definitely for the experienced crew.
Tuesday the 11th holds onto that 10ft, 17-second swell in the morning, and drops to 8ft in the afternoon. Wednesday the 12th is a bit of a lull.
Now, here’s the real deal. Thursday the 13th sees a new pulse, with the swell jumping to 12ft from the SSW, with a 17-second period. This is a beast. The wind is moderate cross-off, so it’s going to be a big, powerful, clean day for experts only.
The weekend of the 15th and 16th sees the swell settle back into the 6ft to 8ft range, with periods around 14 to 17 seconds. The wind stays cross-off.
Looking further out, the real gem is Thursday, August 20th. The morning is absolutely pumping with an 12ft SSW swell, an 18-second period, and massive energy. The wind is a light 9 mph, making for a glassy, clean face. This is exceptional for experts. The afternoon holds similar size. This is the standout session of the whole 16-day window, but it’s a long-range call, so keep an eye on it.
The week before that, on the 18th and 19th, we’ve got consistent 10ft SW swell, but the wind is a fresh 19 mph, which makes it a bit of a battle. The energy is still strong, but the chop will be a factor.
The first few days (Aug 7-9) are your best bet for a solid, clean, but manageable session. The later period (Aug 20+) is the one to circle on the calendar for the true big-wave hunters. For a point break like Mawi, that long-period groundswell is going to wrap in beautifully, but those 10ft+ days are strictly for the experienced.
Rusty out.

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.
