Right, let's get into it.
We've got a solid run of surf coming up here at Downtowns (reef) , starting right now. The water temp is about what you'd expect for this time of year, nothing unusual.
It starts off a bit slow on Tuesday with a modest 5ft SW groundswell. The period is a nice long 16 seconds, which will bring some good energy, but the cross-off wind will leave it a touch lumpy. Not the best. The combined energy (933) is moderate.
Then things really start to crank from Wednesday, July 8th. We see a nice jump, with a 6ft SSW swell pushing the energy up into a strong range (1811). The wind is still cross-off but lighter, making for much cleaner conditions. This is for the more experienced crew, as it's pushing 6-7ft.
Thursday, July 9th holds similar size, but the wind picks up a bit. Friday, July 10th is looking like a real standout. The swell sits nicely around 6ft to 6ft, coming from the SW with that long 16 second period. The wind is a gentle breeze from the ESE, keeping the surface clean. The energy is solid (1756). This window, from Friday morning through to Saturday afternoon, is where it's at.
Saturday, July 11th actually sees the wind go light offshore in the afternoon, which will be *primo* for a reef break like this. The swell drops a touch to 5ft, but that's a perfect size.
There's a drop-off on Sunday, July 12th. The swell fades to under 3ft with the wind going dead glassy. It'll be small and clean, okay for a log.
We get another pulse kicking in around Monday, July 13th, with a very long-period 21 second swell showing in the afternoon. That’s proper groundswell, and with glassy winds, it'll be super clean. The energy (874) is moderate, but the quality will be off the charts.
The middle of the second week, around Tuesday and Wednesday, July 14th and 15th, brings another solid push, with the swell back up over 6ft and energy in the strong range (2188). The wind turns offshore on the Tuesday afternoon, making for some excellent, powerful waves for experienced surfers.
The last few days of the run, from July 18th onward, see a drop in size but the quality holds, with light winds and clean, glassy conditions, especially on the 17th afternoon. Sunday, July 19th sees a final spike in size before it tails off again into the 20th.
The standout: For my money, the best windows are Friday, July 10th through Saturday, July 11th. You've got a solid 6ft SW groundswell with that long period, light winds, and clean surf. The second real highlight is Tuesday afternoon, July 14th, when the offshore wind meets a strong 6ft SSW swell. That’s top-tier quality for those who know what they're doing.
It's a proper reef, so it's an advanced wave. Crowds can be a factor here sometimes, so get on it early.

Information about the Downtowns Surf forecast
The above surf forecast table for Downtowns provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Downtowns can be found by selecting the local surf guide option on the grey menu. Our Downtowns 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 (Downtowns) 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 Downtowns 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.
Downtowns is 57 km (35 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.
