The Lowdown
Alright, let’s get into it. The first few days are a bit of a grind, but the ocean’s got some life in it. We’ve got a solid window of SSW groundswell lining up, but it’s not all clean cut. The wind’s mostly cross-off, which keeps things semi-organized, but the tide is going to be your main enemy. Don't expect perfection until we get further into the run.
The early part of the week, starting Saturday the 8th, is looking average. There’s swell in the water – around 8ft at 16 seconds – but the scores are low due to tide issues. The energy is there, clocking in at 2900, but it's not coming together. Sunday the 9th is much the same, solid 8ft and 7ft sets, but still that 'marginal' tag hanging over it. You’ll get waves, but you’ll be working for them. The water temp is 79°, which is right on the money for this time of year, so no worries there.
Now, Monday the 10th is where things start to get interesting. The morning is a bit softer at 6ft, but the period jumps to 19 seconds – that’s real groundswell. The afternoon, though, is where the size kicks up to 10ft with an 18-second period. The energy is pumping at 5622. Still, the tide comment is a bit of a bummer, so you’ve got to pick your moment. Tuesday the 11th keeps that size around 10ft, with a slightly shorter 17-second period. The energy remains strong, over 5300. These two days have the best size and period combo, but the conditions are still not perfect.
The middle of the week, Wednesday the 12th and Thursday the 13th, settles into the 8ft to 10ft range. The period drops a touch, but the energy is still moderate to strong. The wind stays cross-off, which is okay. The tide is still a factor, but there are waves to be had. The standouts in this stretch are the Monday afternoon and Tuesday sessions – that’s where the size and period are lining up.
Then we get a bit of a lull from Friday the 14th through to Monday the 17th. Swell backs off to the 5ft to 7ft range, and the period drops too. It’s still rideable, but it loses that punch. The wind is lighter, which will help keep it clean, but the energy is way down. If you’re a beginner, this is actually a better window – the size is more manageable.
The back half of the run, from Tuesday the 18th, starts to build again. We see a push back up to 6ft and 6ft, and then Wednesday the 19th and Thursday the 20th bring back the 10ft swell with a 17-18 second period. The energy is strong, around 5000. The wind, though, is freshening up to 30 km/h, so it’s going to be a bit more challenging. Not ideal, but it’s big.
Now, for the real standout. The best looking day on the whole charts is Friday the 21st. The morning shows an 12ft SSW swell at 17 seconds, with an energy reading of 6578 – that’s the strongest we see. The wind is cross-off from the ESE at 25 km/h, which is the best wind direction we get. The afternoon is still solid at 10ft, but the morning is the pick. This is the one to circle. It’s a week and a half out, so don’t book your flights yet, but it’s the one with the most potential.
After that, Saturday the 22nd and Sunday the 23rd back off a bit, with the swell dropping to the 7ft to 8ft range. The period is still decent, but the energy is on the way down. The wind picks back up to 30 km/h on the Sunday, so it’ll be a bit lumpy.
So, for the pick of the litter, it’s Monday and Tuesday this coming week for the quality, but the Friday the 21st is the big one, provided the wind plays ball. It’s a long way out, so treat it as a promising possibility, not a guarantee. The break here at Mawi is a reef, so it handles the long-period swell a lot better than a beach break would. Just keep an eye on the tide.
Stay salty.

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.
