Alright folks, Rusty here with a look at the coming weeks. We've got a solid run of surf on the cards, so let's get into it.
This is all about Scar Reef – it's a sheltered reef and point, and right now it's firing. The water's sitting at a warm 82°, which is a touch warmer than normal for this time of year. Wind is looking like a major player in our favor, with offshore conditions locking in for a big stretch starting this afternoon.
The action kicks off Sunday morning (July 5th). It's glassy, dead calm, with a clean 6ft SSW groundswell pushing in at 15 seconds. The energy is solid (1483). This is the kind of session you dream about. That glassy, morning window with no wind is a gift.
The run stays strong through the week. Wednesday (July 8th) and Thursday (July 9th) are the true standouts here. Swell is pumping up to 7ft from the SSW, period holding at a long 15 seconds, and those clean, offshore winds are locked in. The energy is surging into the very strong range (2043 and 2096). This is big, powerful reef surf – definitely for the experienced crew only.
There's a solid stretch of good waves all the way through until the weekend of the 11th to 12th, where we see a drop in size down to 3ft and the energy fades to moderate (425). The wind stays favorable, so it's not a write-off, just smaller.
Looking further ahead, things pick up again. Monday, July 13th afternoon sees a jump back to 5ft with a very long 19-second period, and that’s followed by Tuesday, July 14th morning which delivers another excellent pulse of 7ft SSW swell, with very strong energy (2658) and clean offshore wind. Again, that's expert territory.
The pattern settles back into a fun, consistent groove for the second week, with clean 5ft to 6ft SSW swells holding period in the 14-15 second range. By Sunday, July 19th, we’re back to a very good 6ft SW swell. The whole run is persistent and clean. A really solid forecast.
Rusty out.

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.
