G’day, Rusty here. Alright, we’ve only got one spot on the radar this time: Wanjapu. It’s a reef setup and exposed to the SW swell, so when the ocean sends something our way, this place can really light up. The water’s sitting at about 81°, which is pretty much bang on average for this time of year, so no surprises there.

The next couple of days are a bit of a write-off, to be honest. The swell’s there, around 5ft to 6ft from the SSW with a solid 14 to 15-second period, but the wind’s coming from the SE, putting a cross-chop on things. The energy’s there, but the quality is marginal. It’s frustrating because the building blocks are good, but the wind is just messing it up.

Then we get a window on Sunday morning, 5th July. This is your standout. The wind goes glassy, dead calm, and you’ve got a clean 5ft SSW groundswell with a lovely 15-second period. The combined energy is pumping. For an advanced reef break, this is about as good as it gets. The swell direction (SSW) is a perfect match for the optimum. Just know that crowds are a possibility here sometimes, so get in early. This is the best on offer by a country mile.

After that Sunday morning high, the wind gets messy again through the week. We’ve got a building swell from the SW from Wednesday 8th into Thursday 9th, pushing 6ft to 7ft with 15-second periods and big energy readings. But, the SE wind is cross or cross-shore all the way, so it’ll be chopped up. For experienced surfers, there’ll be some size out there, but it won’t be clean. Given the size and the wind, this setup might actually be more interesting for kite surfing than paddle surfing.

We get another little reprieve on Sunday morning, 12th July. The swell drops to 4ft from the SW, but it’s glassy again with a 14-second period. The forecast says “very good surf conditions,” so it’s worth a paddle if you’re keen on a clean, smaller session.

Then, another glassy slot on Monday 13th July. The swell is tiny in the morning, only 2ft from the SSW but with an incredibly long 20-second period—proper groundswell. The afternoon picks up a touch to 3ft from the SSW with an 18-second period. Again, glassy. These are clean, small days for those who just want to get wet without the wind hassle.

The rest of the fortnight into the third week is pretty average. Swell hangs around 3ft to 5ft from the SW, but it’s almost always crossed-up by the SE wind. Not much to get excited about. There’s no other standout beyond that Sunday 5th. That’s your session. Don’t sleep on it.

Rusty.

Information about the Wanjapu Surf forecast

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

Wanjapu is 24 km (15 miles) from the city of Adalara. If you plan a holiday in Sumba, look for hotels and other accommodation in Adalara. Adalara has rooms for a wide range of budgets as well as car hire and transport links.
