The Lowdown

Alright, Rusty here. Let’s have a look at what’s in store for Wanjapu over the next couple of weeks.

Right off the bat, we’ve got a solid run of swell from the get-go, but the conditions are gonna be a bit of a mixed bag. The real standout window is shaping up to be Wednesday morning, July 15th. That’s the pick of the first week. We’re looking at a clean 7ft SSW swell with a 16-second period and glassy conditions. The water’s sitting at 80°, which is about normal for this time of year. That long-period groundswell is gonna have a heap of energy behind it (combined energy of 2212) and it’s exposed to the SW, so the reef at Wanjapu is going to be handling it nicely. This is one for the experienced crew though, as it’s a solid size and a reef break.

The rest of the week is a bit of a struggle. Tuesday afternoon, July 14th, is cross and a bit messy. Thursday the 16th and Friday the 17th see the swell dropping a little, with cross-shore winds keeping things from being truly clean. The mornings are generally the better call, but the wind is often cross or cross-on. Saturday afternoon, July 18th, is worth a mention too – the swell dips to 5ft from the SW, but we get a clean, cross-off breeze and the energy is still moderate (950). It’s not the standout, but it’s a nice little window.

Now, after a few days of average to poor conditions, the forecast picks up again. Monday July 20th brings a bigger pulse of swell – 7 to 8ft from the SSW with a period of 16 to 17 seconds. That’s a lot of water moving around (combined energy peaking at 2611). The Monday afternoon looks cleaner with a cross-off breeze, but it’s still a bit on the big side for the average punter. Tuesday July 21st and Wednesday July 22nd are a bit less interesting, with the swell dropping and the wind staying cross.

The second week settles into a more moderate pattern. There’s no huge standout, but a few mornings are worth a look. Friday July 24th afternoon has a clean 4ft SSW swell with a cross-off breeze and a combined energy of 596. Then the real dark horse comes in the final days. Tuesday July 28th morning is glassy, with a 3ft SW swell and a very long 20-second period. The energy is moderate (953), but that period is dreamy for a reef like Wanjapu. The real gem is Wednesday July 29th morning – glassy conditions, 4ft SW swell with an 18-second period, and a combined energy of 1044. This is going to be clean, lined-up, and perfect for the experienced surfer. It’s a long way out, so keep an eye on it, but it’s got the makings of a magic session.

Overall, Wanjapu is a consistent spot, but the conditions are only going to be truly good on a few select windows. The best bets are the morning of Wednesday July 15th and the glassy mornings of Tuesday July 28th and Wednesday July 29th.

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.
