The Lowdown

Alright, Rusty here again, but in feet this time. Let’s talk Mawi.

This reef break is looking pretty consistent from Sunday the 16th through the end of the month. No real gaps in the action.

Sunday morning kicks off with 7ft SSW groundswell, and it’s got some serious energy – the combined number is 2472 (strong). Water temp is 80°, about normal for this time of year. Winds are cross-off from the southeast, so it’s clean. Monday brings 5ft to 5ft, still clean and rideable. Tuesday the 18th drops a bit to 4ft in the morning, but the period stays at 16 seconds, keeping the shape nice.

The big one is Wednesday the 19th. We’ve got 8ft SW swell, with a period of 18 seconds – that’s a long-period groundswell, and on a reef, that’s going to line up beautifully. The combined energy hits 4009 in the morning and 4517 in the afternoon (very strong). Winds stay cross-off from the southeast at 15 km/h, so it’s clean. This is the standout window, but at 8ft, it’s for experts only.

Thursday the 20th stays big – 10ft in the morning, dropping to 8ft in the afternoon, still clean. Energy stays in the 4000s and 3000s. After that, the swell settles into the 6ft to 8ft range through the weekend and into the next week. Winds pick up a bit, hitting 25 to 30 km/h around the 21st and 22nd, but still cross-off.

Around the 26th, it drops off – 4ft to 5ft, energy under 1000. But it bounces back on the 27th with a 6ft to 7ft SW swell and a 19-second period, energy back up near 3000. That’s a promising window, but it’s further out, so a bit less certain.

Crowds at Mawi can show up sometimes, so don’t expect it to be empty, but it’s not a madhouse. Early mornings are your best bet for less company. Beginners, stick to the smaller days like the 18th or the 29th when the swell is under 5ft. Everything bigger is for the experienced crew.

Keep your eyes on Wednesday the 19th and that late-month swell around the 27th. That’s where the magic is. 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.
