The Lowdown

Alright, grab your board – let’s talk about what’s coming up for Wanjapu over the next couple of weeks.

We’ve got a solid run of swell on the cards, but it’s not all clean, open windows. The whole period is dominated by a long-period SSW groundswell, with periods ranging from 15 down to 13 seconds, and at times topping out at 18 to 23 seconds – that’s proper energy, but it’ll be a bit straight at the beach. This is a reef break, so that long-period stuff will actually line up nicely, giving you some real shape. The combined wave energy is strong to very strong throughout, with values like 2672 at the start and even hitting 4484 at one point, so there’s plenty of push.

The water temp is around average for this time of year, nothing weird going on there.

The standout session is Saturday morning, August 15th. The wind goes glassy, the swell is 8ft from the SSW with a period of 19 seconds, and the combined energy is a beefy 3870. The conditions are rated excellent for experienced surfers – and that’s a proper call. It’s a reef break, so that long-period groundswell will groom into nice lines. You’ll have the place mostly to yourself too, as crowds are only occasional.

The other one to circle is Wednesday morning, August 19th. Again, glassy conditions, with an 8ft SW swell, 18-second period, and combined energy of 4156. Another excellent call for the seasoned crew. It’s a bit of a wait, but it looks promising.

The first week does have plenty of swell, but the wind is mostly cross or cross-onshore, which puts a bit of bump on the face. You’ll still find waves, but it’s not the cleanest. Thursday afternoon, August 6th, is a small highlight with clean conditions and a 7ft SW swell, and the cross-offshore wind will keep it tidy. After that, it’s a lot of ‘marginal’ notes with cross-chop, especially from the 10th through the 13th, where the wind picks up and the quality drops off.

From the 16th onwards, the swell starts to ease back, dropping from 7ft to 4ft by the 18th, and the energy falls off too. The wind stays mostly cross or cross-on, so it’s a bit of a fade-out. But again, that 19th is a cracker.

Overall, the best bet is definitely the two glassy mornings – August 15th and August 19th. If you’re happy with a little texture, the first week has plenty of size, but the real gold is waiting for that glass.

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.
