The Lowdown

Alright, Rusty here, lookin' at the charts for Scar Reef. We've got a solid run of surf coming through, so get your gear ready.

The pattern is setting up nicely. We start on Tuesday, July 28th, with a clean 3ft SSW groundswell rolling in. It's a long period, 16 seconds, which means proper lines and easy paddling. The wind's light offshore from the SE, so it'll be glassy. Water temp is sitting at 80°, pretty much normal for this time of year. The combined swell energy is moderate, reading 557. It's a good, mellow start to the week.

Wednesday, July 29th, the swell bumps up to 4ft to 4ft with the same SSW direction. The period drops slightly to 14 seconds, but it's still solid groundswell. Offshore winds hold from the SE, keeping conditions clean. Energy builds to 727–779. Good fun on the cards.

Now, Thursday the 30th is where it starts getting tasty. We've got a 4ft SSW swell with a long 15-second period in the morning, and the energy jumps to 1338. Winds are light offshore again. The afternoon gets even better with a 3ft swell but a very long 19-second period, driving the energy to 1499. Clean, lined-up waves, and it's a reef and point setup at Scar Reef, so those long-period groundswells will wrap in beautifully.

Friday the 31st keeps the quality high. A 4ft SSW swell, 17-second period, with clean cross-offshore winds. Energy is strong at 1603. The afternoon glass-off with 4ft SW swell and 17 seconds is a beauty. This is a standout window for the first week.

Saturday, August 1st, is another ripper. Morning has 5ft SSW, 16-second swell, clean. Then by afternoon it goes glassy, with the swell pushing 6ft and 17 seconds. Energy at 1677. This is excellent.

Sunday, August 2nd, is the big one for the first week. Morning glass, 7ft SSW, 16-second groundswell. Energy is 2093. By afternoon, it's 7ft, 17 seconds, energy 2376. This is expert territory now—over 7ft—so if you're not confident, give it a miss. For those who are, it's unreal.

Monday the 3rd sees the swell drop back to a very clean 6ft, 15 seconds, still glassy. Energy is 1321–1315. A great follow-up day.

Tuesday the 4th to Wednesday the 5th sees the swell settle into a consistent 5ft to 6ft range, with clean cross-offshore winds. Period sits at 14 seconds. Good, solid surfing.

Now, here's where the second week really stands out. Thursday, August 6th, we're back up to 7ft SSW, 17 seconds, with light offshore wind. Energy is 2468. By afternoon, it's 7ft, 17 seconds, 2581. This is the best on offer for the entire outlook. Clean, powerful, groundswell wrapping into the reef. Expert territory, but for those ready for it, this is the session to target.

Friday the 7th stays solid but the wind picks up. Morning has 8ft, 16-second SSW groundswell, energy 3032, with a moderate offshore wind. By afternoon the wind gets stiffer, 16 mph, and the quality dips a bit—it's more for kite surfing than paddle boards. Still, the morning is excellent for experts.

Saturday the 8th brings a massive shift. Morning has a 4ft swell, but the period jumps to 23 seconds—very long period. Energy is still high at 2964. By afternoon, we get a 8ft, 20-second SSW groundswell and the energy rockets to 5653. Strong, long-period groundswell. Clean conditions. This is a standout for the second week, but the very long period means it'll be best on the reef and point at Scar Reef, not for a beach break.

Sunday the 9th sees the swell peak at 12ft, 18 seconds, but the wind turns cross-offshore and stiff. Conditions get messy. For all but the most expert, this is a pass.

Monday the 10th drops back to a cleaner 8ft, 16-second SSW swell, with moderate offshore winds. Energy holds strong between 3336–3740. Another excellent day for experienced surfers.

Tuesday the 11th stays at 8ft, 15-second period, with clean cross-offshore winds. A solid option.

Wednesday the 12th wraps it up with 8ft, 15-second SSW swell and clean offshore winds. Energy sits at 2261–2705. A great way to finish the outlook.

So, the standouts are clear: Thursday, August 6th is the absolute best day—clean, 7ft, long-period groundswell, perfect wind. Saturday, August 8th afternoon is the other one to circle: huge energy, very long period, clean. Both are expert waves. Crowds are possible at Scar Reef, but with this quality, a few more heads might be there. If you're good enough, you'll be smiling.

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.
