The Lowdown

Alright, Rusty here. Let’s break down what’s coming.

The surf kicks off on Tuesday, July 14th, and we’ve got a solid run of swell ahead, but for the first few days the wind is going to be a bit of a headache. It’s mostly coming across the face or on it, putting a little chop on the waves. That long-period groundswell from the SW is packing a lot of punch, but the wind isn't giving us the clean surface we’d want.

The real standout, the one to save your energy for, is Friday afternoon, July 17th at Wanjapu. The wind shifts just enough to go cross-offshore, cleaning up that 5ft SW swell perfectly. The period is a juicy 16 seconds, so those waves will have some serious power. The water temp feels pretty normal for this time of year at about 80°. That Friday afternoon session is the best quality you’re going to see. Just know it can be a bit of a zoo crowd-wise, as word gets out.

For the rest of the first week, mornings are honestly a bit of a grind. The breeze is light but cross-on, putting tiny ripples on a decent 5ft to 6ft swell. It’s not a write-off, but it’s not the gem that Friday is. The ocean energy stays solid right through the weekend, so there’s plenty of push, but that onshore element keeps it from being glassy.

Into the second week, the swell starts to drop. We see another pulse of 6ft+ SW swell on Monday, July 20th, but with the same cross-wind story. It’s a bit messy. By Thursday, July 23rd, the waves fade to around 4ft, but we get another window of clean surf on Thursday afternoon. After that, from around July 25th on, it’s a slow fade. The swell drops under 3ft, the energy falls off a cliff, and with the persistent cross-shore wind, it gets pretty marginal. By July 27th, it’s mostly flat and poor.

So, to put it simply: Friday the 17th afternoon is your golden window for some real quality. The rest is surfable, but you’ll be working for it. Don’t get your hopes up for the last week of the month.

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.
