The Lowdown
G’day, I’m Rusty, and I’ve been chewing on the charts for your area. Right now, there’s a solid run of groundswell coming in, but it’s not all clean. The main spot is Baya Reef, a proper advanced reef break that’s open to the SW swell. The water temp is running about average for this time of year, so nothing wild.
The first recommended surf is on Tuesday morning, August 18th. A clear morning with a light cross breeze at 3.1 mph from the south. The swell is 6.9 ft from the SSW at a very long 16 seconds, packing in 2148 of combined energy. That’s a lot of power, but the reef will handle it well. The cross-shore wind is light, just a few ripples, so it’s glassy enough to be a real treat. This is a standout – clean, solid, and consistent.
The next morning, Wednesday, August 19th, the swell jumps to 8.2 ft from the SSW with an even longer 18-second period, and the energy is 4354. The wind is cross-on from the south at 6.2 mph, so it’s not perfect, but for the size, it’s still workable. The morning is the pick – that kind of energy on a reef will draw in some beautiful lines. The afternoon gets lumpy with a 12.4 mph wind.
Thursday, August 20th, the morning cleans up with a clear sky and a light cross breeze from the SSE at 6.2 mph. The swell is 8.2 ft from the SW, period 16 seconds, energy 3238. That’s another top session for experienced surfers – the reef will be handling the size, and the wind is nearly glassy. The afternoon gets messy with a 15.5 mph cross-breeze, so get on it early.
The pattern holds through Friday, August 21st and Saturday, August 22nd, with the swell at 6.6-6.9 ft from the SSW, 15-17 second periods. The mornings are the go with light cross breezes. The energy stays in the 1900-3100 range, so plenty of grunt.
There’s a rough patch from Sunday, August 23rd through to Tuesday, August 25th. The swell drops to 4.9-5.6 ft, and the wind gets stronger, with afternoon gusts up to 21.7 mph. The morning of the 25th offers a clean moment with a cross-off breeze from the SE at 12.4 mph and 4.9 ft swell, but it’s short-lived.
From Wednesday, August 26th to Friday, August 28th, the swell dips to 3.6-4.9 ft, and the energy drops to 767-1149. The mornings stay clean with cross-off winds, but the waves are small. The afternoons are blown out.
But Saturday, August 29th morning, the swell comes back strong. 4.9 ft from the SW at a very long 19 seconds, with 2086 of combined energy. The wind is light from the SSE at 6.2 mph, creating a cross-shore with just small ripples. That’s a sneaky good session.
The second week has a real standout: Sunday, August 30th morning. The swell is 6.9 ft from the SW, 17-second period, energy 2799. Light cross breeze from the SSE at 6.2 mph. The reef will be firing, and it’s clean. The best session of the week.
Monday, August 31st morning is another beauty – 6.9 ft from the SW, 16 seconds, and a huge 3854 of energy. The wind is a gentle cross breeze from the SSE at 9.3 mph, so just a little texture but still very good. The afternoon sees 7.9 ft and 5542 energy, but the wind jumps to 18.6 mph and gets lumpy, so the morning wins.
Tuesday, September 1st morning stays solid – 8.2 ft from the SW, 17 seconds, energy 3865. A gentle cross breeze keeps it clean. The afternoon has a risk of thunderstorms, so the morning is the move.
Wednesday, September 2nd morning wraps it up with 8.2 ft from the SSW, 16 seconds, energy 3996, and a light cross breeze from the SSE at 6.2 mph. Clean and powerful.
The absolute best of the whole 16-day window? The Tuesday, August 18th morning session – that light cross breeze, the 6.9 ft SSW groundswell at 16 seconds, and the reef working perfectly. And the Sunday, August 30th morning, with the swell back up and glassy conditions. Two standouts, both for the early morning crew.
This is a reef break for advanced surfers only – 8.2

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.
