Table - best surf conditions forecast for Scar Reef over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Scar Reef. This is a reef-and-point setup, an advanced wave that’s fairly consistent and handles a SW swell best. The water temp is sitting pretty much average for this time of year, so no weird surprises there.
We’ve got a solid run of surf ahead, but it’s a slow starter. The first real window opens up on Monday, July 13th, with a clean but modest 3ft SW swell pushing in. The energy’s already moderate at 615, and with glassy conditions in the morning, it’s a nice, easy paddle to warm up. By the afternoon, it drops a touch to 3ft, but the wind goes cross-off and the period jumps to 21 seconds – that’s a long-period groundswell that will wrap beautifully into the point, offering some proper lines, though the sets will be spaced out.
Now, the standout. Tuesday, July 14th is where it gets serious. The morning delivers 6ft of SSW swell with a 17-second period and combined energy hitting 2293 – that’s strong, pushy water. The wind is light cross-off, keeping it clean. This is excellent surf, but at this size, it’s firmly for experienced surfers only. It holds through the afternoon at 7ft and even builds into Wednesday, July 15th, with 7ft in the morning and a textbook offshore wind from the SE. The energy is huge at 2264. This is the best on offer: big, powerful, and clean. If you’re an expert, you do not want to miss that Wednesday morning session.
The quality stays high through Thursday and Friday, with 5ft to 5ft SW swells and offshore winds, keeping the surface smooth. The energy backs off a little but is still moderate. Saturday, July 18th sees a slight drop in energy, but the waves hold at 5ft with offshore winds, so there’s still fun to be had.
After a brief dip, there’s another pulse. Monday, July 20th brings back the big stuff: 7ft SSW swell, 17-second period, and a massive 2683 energy reading. That’s expert territory again, and it’s clean with light cross-off winds. The following days settle into the 5ft to 6ft range, with mostly cross-off or offshore winds, keeping the reef working well.
The last week of the forecast shows a gradual fade. Saturday, July 25th and Sunday, July 26th still have some punch – 6ft SSW with long periods and moderate energy – but the winds are more cross-off, so it’s still clean. By Monday, July 27th and Tuesday, July 28th, it’s dropping to 4ft to 5ft, smaller but still rideable for the keen ones.
Overall, the highlight is Wednesday, July 15th morning – that’s the one to circle. Big, clean, and powerful. The crowd factor at Scar Reef is occasional, so you might get a few out, but it’s worth the company.
Rusty.

Information about the Scar Reef Surf forecast
The above surf forecast table for Scar Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Scar Reef can be found by selecting the local surf guide option on the grey menu. Our Scar Reef 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 (Scar Reef) 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 Scar Reef 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.
Scar Reef is 55 km (34 miles) from the city of Praya. If you plan a holiday in Sumbawa, 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.
