The Lowdown

Alright folks, Rusty here. Let’s break down what’s cooking for the next couple of weeks. We’ve got one spot on the menu, and it’s a reef setup that knows how to handle a proper swell, but you’ve gotta be sharp to surf it.

The pattern kicks off with a solid, long-period groundswell from the southwest. This isn’t weak energy; we’re talking a serious push of power with combined energy readings in the thousands (3700+), which is strong to very strong. The water temperature is sitting at 80°F, which is pretty much spot on average for this time of year, so no surprises there.

The first real action starts on Tuesday, the 8th of September. The swell is a solid 6 ft from the SSW with a very long period of 18 seconds. That’s proper groundswell. The wind is a cross-off from the SSE, blowing at 12 mph – that’s going to keep the surface clean. This is a reef break, so that long period energy is going to wrap in nicely, offering up some well-shaped, powerful lines. The standouts here are the Wednesday, the 9th of September, with the swell jumping to 8 ft from the SSW (16 seconds), and Tuesday the 22nd of September, which is a real eye-popper. That Tuesday sees a big jump to 12 ft from the SSW with an 18-second period and combined energy hitting over 7600. That is serious, expert-level only, and it’s a week and a half out, so keep an eye on it, but it’s promising.

Most of the period is filled with waves in the 5 ft to 8 ft range, with that cross-off wind holding steady. The Friday the 18th of September morning and afternoon look particularly sweet. The swell drops to a more manageable 5-6 ft from the SSW, but the wind drops to a light breeze of 6 mph, making for glassy, nearly perfect conditions. That’s a true gem for experienced surfers looking for a clean session without the crowd being too crazy.

There is a slight dip in size around the 19th and 20th, with swell dropping to 5 ft, but it’s still rideable. The whole run is fairly consistent, so you won’t be staring at flat water. Just remember, this is a reef break for advanced surfers, and with that long-period swell, the sets will have some punch and the lulls between them will be longer, making the paddle out a bit easier. Crowds are only a sometimes thing here, so you’ve got a good chance of snagging some waves.

There are no gaps without surf to speak of; the swell keeps rolling in.

Rusty, signing off.

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.
