The Lowdown

Right, Rusty here. Let's break it down.

We've got a solid, consistent run of surf coming our way. Mawi is the only spot, and she's looking good, but keep in mind this is a reef break for advanced surfers only. The water temp is bang on average for this time of year at about 80°.

This whole 16-day stretch has waves on offer, no real gaps to speak of. The action kicks off on Monday the 17th with a clean 5ft SSW groundswell and a healthy 14-second period. The wind is a cross-off breeze from the SE at 9 mph. It's got moderate energy (1107), and while it's good for experienced surfers, the conditions are just "marginal" in the afternoon, so get out early.

Tuesday the 18th looks similar but with a bump in period to 16 seconds. The combined energy jumps to 2314 in the morning, with 5ft SSW swell. Again, clean and cross-off. The afternoon gets a little bigger at 6ft and more energy (2594), though the tide might play games. Wednesday the 19th is the true standout of the whole run. The swell pulses to 8ft from the SW with a very long 18-second period. That's serious groundswell. The morning is clear with that steady 9 mph cross-off breeze and the wave energy is pumping at 4024. This is the day for it, but at 8ft, this is expert-only territory. The afternoon quality dips due to tidal issues and some clouds, but the numbers are even higher at 4510. That is some powerful water.

Thursday the 20th holds at a solid 10ft in the morning, but the wind picks up to 12 mph. Still cross-off, but it's not the same glass. The energy is still huge at 4109. This is another big, heavy day for the experts. The rest of that week into the weekend (21st to 24th) is a run of punchy 6 to 8ft SSW swell with a steady 9 to 16 mph cross-off wind. The energy levels drop but stay in the moderate-to-strong range. The winds are consistent, so the surface will be clean, but the tidal comments keep the scores down.

Moving into the second week, from the 25th onwards, the swell steps down. Tuesday the 25th offers 6ft SSW swell with a moderate 14-second period and energy levels just over 1200. The 27th of August is interesting; the swell is only 4ft, but the period stretches out to 18 seconds, giving a surprising 1411 energy reading. It's a tricky one for a reef. The end of the month, around the 30th and 31st, sees another pulse. On Sunday the 30th, we get 5ft SW swell with an 18-second period and 2019 energy. By Monday the 31st, it's up to 7ft from the SW with a 16-second period and 2494 energy. It's big, but the wind is still a moderate cross-off.

The real standout for the whole outlook is Wednesday the 19th of August. It's the biggest, cleanest, most powerful day of the whole run. The 8ft SW groundswell with that 18-second period is a proper event, but it is strictly for experts at this heavy reef. Get on it early.

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.
