The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Mawi over the next couple of weeks.
Right off the bat, I gotta be straight with you: the surf is on the small side and the wind is a persistent cross-off. It’s not a total washout, but we’re not looking at anything firing for a while. The first proper recommendation doesn’t kick off until Sunday, the 19th of July. From there, we’ve got a long stretch of marginal conditions, with the best waves showing up much later.
The water temp is about average for this time of year, so no nasty surprises when you get in.
Sunday, July 19th – The swell is 4.3ft from the SW with a solid 13-second period. That’s decent groundswell energy, but the wind is a moderate to fresh breeze from the SE at 15-19 mph, keeping things a bit bumpy. The combined energy is moderate (854). It’s surfable, but nothing to write home about. The tide might mess with it a little.
Monday, July 20th – The swell bumps up to 6.6ft from the SSW, with a very long 17-second period. That’s proper groundswell, and the energy is strong (2639). But the wind is still cross-off at 19 mph. This is a big, powerful wave for Mawi, and it’s a reef break. At 6.6ft, it’s getting into expert territory, especially with that long period making it fat and fast. If you’re experienced, it could be a fun session, but it’s a bit of a battle.
Tuesday, July 21st – Still a solid 5.9ft from the SW with a 14-second period. Energy is moderate (1340). The wind hasn’t eased off. It’s a similar story – okay for the advanced crew, but not clean.
Through the rest of the week (July 22nd to 25th) – The swell drops steadily. By Thursday and Friday, we’re down to 3.3ft to 3.6ft from the SSW, with periods around 13-14 seconds. The energy is weak (under 750). The wind is still a fresh cross-off. It’s small, and it’s not clean. Honestly, not worth rushing out for.
Saturday, July 26th – A shift in direction: swell from the SE at 5.9ft, but the period is short, only 7-8 seconds. That’s weak windswell, and the energy is moderate (744). The wind is slightly lighter at 12 mph, but the waves will be a bit crumbly and disorganised. Not great.
Sunday, July 27th to Wednesday, July 29th – The swell goes back to a small SW groundswell, 3.0ft to 4.3ft, with periods of 13-17 seconds. The wind is a gentle to moderate breeze, so the first few days of this week are actually the cleanest we’ve seen. The energy is weak to moderate (555-768). It’s small, but if you’re patient, you might find a few nice, clean lines on the morning of the 27th or 28th. The best bet in this whole stretch is Tuesday, July 28th morning – 3.0ft from the SSW with a 17-second period, and a gentle breeze from the SE at 12 mph. That’s glassy, clean conditions. The wave will be small but well-shaped and long. It’s not a standout, but it’s the most pleasant option.
Thursday, July 30th to Friday, July 31st – The swell direction shifts back to a long-period SW groundswell, with periods of 18-21 seconds. The energy is strong (up to 1822). The swell height is 3.9ft to 4.3ft, but the wind is back up to a fresh 19 mph cross-off. The waves will have power, but they’ll be a bit messy.
Here’s the main event: Saturday, August 1st – This is the standout. The swell hits 7.9ft to 8.2ft from the SW, with a 17-18 second period. That’s a very strong groundswell, and the combined energy is very high (3696). The wind is a fresh cross-off from the ESE at 19 mph. This is a big, powerful, expert-only wave. At over 8ft, it’s only for the brave. The long period will make it break fast and straight on the reef, so it’s not for the faint-hearted. The wind is still cross-off, so it won’

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.
