The Lowdown

Alright folks, Rusty here. We’ve got a 16-day window ahead for Mawi, and it’s a bit of a slow cooker. The forecast kicks off with some surf, but it’s not the kind you’ll be writing home about just yet. The whole period is dominated by a cross-offshore wind, which keeps things clean, but for the first week, the size and quality are just too marginal to get excited about. There’s a solid run of days from late July into early August where things really start to look up, so hold your horses.

The first real surf on offer is from Tuesday, July 21st. Mawi (reef) is seeing a 6ft SSW swell with a 14-second period. That’s a decent groundswell, but the wind is a fresh 22 mph cross-offshore. The combined energy is moderate at 1635, but the call is a 2/10 for a reason – it’s just not that good. The water temp is about average for the time of year, nothing wild. The wind stays strong and cross-off through the week, with the swell dropping to 3ft by Friday, July 24th. That afternoon, the period jumps to 17 seconds, but the height is tiny, so don’t get your hopes up.

Saturday, July 25th afternoon, things get a bit more interesting with a 8ft SE swell, but the period is a short 9 seconds, and the wind is still a fresh 22 mph cross-off. The energy is strong at 1466, but it’s still a marginal call. Sunday, July 26th is a write-off – strong breeze and poor conditions. Then Monday, July 27th morning, we get a 7ft swell with short period (8 seconds) and a moderate breeze, scratchy but clean.

Now, listen up. The standout window starts to appear on Thursday, July 30th. That morning, the wind goes glassy, dead calm from the SSE at 3 mph. The swell is a clean 5ft from the SSW with a long 16-second period. The energy is strong at 1395, and the report says it’s excellent for experienced surfers. This is the one to aim for. The tide conditions are questionable, but that glassy wind makes it the best early call in the whole forecast.

The real gem, however, is the first weekend of August. Saturday, August 1st is a cracker. Morning sees a 6ft SW swell with an 18-second period, light 6 mph cross-offshore wind, and an energy reading of 2390. The report calls it excellent for experienced surfers. The afternoon is even better – 7ft SW swell, 17-second period, same light wind, and energy jumping to 2835. This is the best of the best. The swell direction (SW) is right on the money for Mawi’s optimum (SW). The wind is light and clean, and the long period will produce some beautifully shaped, powerful lines on the reef. It’s solid, but at 7ft, it’s expert territory. Sunday, August 2nd is still good, with a 7ft SW swell and 16-second period, but the wind picks up to a moderate 12 mph cross-off, so it’s a step down.

The run continues into the following week. Monday, August 3rd has a 5ft SW swell with a 14-second period and gentle cross-off breeze. Then Tuesday, August 4th morning, the period jumps to a very long 20 seconds with a 5ft SSW swell – that’s a serious groundswell, but it’s going to be super straight at the beach. It’s a reef, so it should handle it, but the energy is moderate at 2350. The afternoon of the 4th sees a bigger 7ft SW swell with an 18-second period and a massive 3984 energy reading – that’s powerful stuff. The wind is a moderate 16 mph cross-off, but the size and period make it a heavy, expert-only proposition. Wednesday, August 5th morning keeps the 8ft SW swell going with a 17-second period and a strong 3202 energy reading, but again, that’s a big, powerful swell for the brave.

So, to wrap it up: the first week is a wash. The real standouts are Thursday, July 30th morning for the glassy conditions and clean 5ft SSW swell, and Saturday, August 1st for the absolute best combination of size, direction, period, and light wind. If you’re an experienced surfer, that Saturday is the one you’ve been waiting for. The later days (August 4th and 5th) are big and powerful, but only for the experts.

This is 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.
