The Lowdown
G’day, Rusty here. Let’s talk about the outlook for Baya Reef. We’ve got an extended run of waves stretching all the way through the 16-day window, but it’s a mixed bag, so I’ll break it down for you.
The overall pattern is a persistent, long-period SSW groundswell hanging around, with a 17-second period to start. That kind of period means the waves have plenty of energy and shape, but at a reef break like this, it can also mean the sets push through a bit fast and straight. The combined swell energy kicks off at a solid 3289 (moderate-to-strong), so there’s plenty of push behind it. Water temp is sitting at 82° with a 0.9° anomaly, so pretty much average for this time of year.
The best window, and the true standout, is the morning of Thursday, 13th August. We’ve got a 8ft swell from the south, 17-second period, with gentle 9 mph cross-shore wind. That’s about as clean as it gets for this spot, with slight cross-chop but nothing to ruin your session. It’s an advanced reef break, so it’s not for beginners, and it can get crowded here sometimes, but the quality on offer early Thursday should be worth sharing a few waves.
Thursday afternoon the wind picks up to 19 mph, making it lumpy and less appealing. Friday morning, 14th August, still has a decent 7ft swell, 15-second period, but the cross-shore wind, while gentle, is still cross, so the surface gets a bit of ripple. Not the top pick.
Saturday, 15th August morning drops to 5ft but the wind is light at 6 mph from the south, and the swell direction swings to SSW. Still cross-shore, but the light breeze keeps it tidy. The combined energy is still moderate at 1814. It’s a good session, but not the best of the run.
Sunday and Monday see a dip in size and energy, with the swell dropping to 5ft and then 4ft. The wind stays manageable but cross-shore, so surfable but not pumping.
Things fire back up on Tuesday morning, 18th August, with a 7ft SSW swell at 16 seconds, and gentle cross-shore wind. The energy jumps back up to 2234, but the wind is still cross, not offshore, so you’ll have a bit of chop to deal with.
The biggest swell of the window arrives on Wednesday morning, 19th August: 8ft at 18 seconds, combined energy of 4403 (strong). That’s a serious amount of water. But it’s still cross-shore wind at 9 mph. For an advanced reef break, that’s a proper expert session. Wednesday afternoon gets even bigger at 10ft, but the wind goes fresh at 19 mph, so it’ll be bumpy and tough.
Thursday, 20th August morning holds at 8ft with gentle cross-shore wind, and the second week continues with similar flavours – mostly 5ft to 8ft swell, often with moderate to fresh cross-shore winds. The mornings are generally the call, with lighter breezes. By the latter part of the second week, from around 25th August, the swell drops below 7ft and the energy weakens into the hundreds, so the punch fades.
In the second week, keep an eye on Tuesday morning, 25th August – it’s only 4ft but the wind goes cross-offshore from the SE at 9 mph, which is as close to glassy as we get here. The period is 16 seconds, so the quality is there, just smaller.
Overall, the standout is Thursday morning, 13th August. Wednesday morning, 19th August is also a standout for size and energy, but with the cross-shore wind, it’s not as clean. If you’re an advanced surfer, those are your sessions.
Otherwise, it’s a long run of mostly cross-shore wind conditions, so the reef will offer waves but you’ll be working with a bit of surface texture most days. The crowd factor sometimes shows up, so keep that in mind.
Rusty.

Information about the Baya Reef Surf forecast
The above surf forecast table for Baya Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Baya Reef can be found by selecting the local surf guide option on the grey menu. Our Baya 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 (Baya 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 Baya 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.
Baya Reef is 35 km (22 miles) from the city of Pelabuhanratu. If you plan a holiday in West Java, look for hotels and other accommodation in Pelabuhanratu. Pelabuhanratu has rooms for a wide range of budgets as well as car hire and transport links.
