Alright, Rusty here again. Let’s look at what’s cookin’ at Wanjapu.

Honestly, for the next couple of weeks, it’s a bit of a battle. There’s plenty of swell in the water, but the wind is gonna be a headache. We’ve got a solid run of decent-sized SW groundswell, but that cross-shore wind from the SE is going to be hanging around, putting a chop on almost everything. It ain’t a total bust, but you gotta pick your windows.

We start out Monday morning, July 6th. There’s 4ft of SSW swell at a long 14 seconds, but a light cross-shore breeze is already making it look marginal. The combined energy is strong at 1162, but the quality ain’t there. That afternoon the wind picks up to a moderate breeze, and it’s the same story. Tuesday and Wednesday are more of the same. The swell builds through Wednesday, hitting 6ft in the morning and 7ft in the afternoon from the SW, with a 15-second period. That’s real energy, with the combined readings hitting 1595 and 1990. But that moderate cross-shore wind is just gonna mess up the face. Frustrating.

The wind stays stiff from the SE right through to Saturday, July 11th, so the surf is gonna have that cross-chop on it every session.

But then, hold up. Sunday morning, July 12th. The wind drops out completely, and it’s glassy. The swell has backed off a touch to 4ft from the SW, but the period is a solid 14 seconds, and the combined energy is a more manageable 549. The data says “expect very good surf conditions.” That’s the morning to be out there. Get in early, because by the afternoon the wind swings back to a moderate cross-shore and it’s done.

The following week is more of the same grind, with a lot of moderate cross-shore wind. Monday afternoon, July 20th, stands out a little – the wind goes cross-offshore and the data says “excellent surf conditions for experienced surfers.” The swell is a clean 5ft from the SW at 15 seconds, with a combined energy of 1148. It’s a clean window, but the word “experienced” is key here.

Overall, the standout is that glassy Sunday morning, July 12th. It’s not the biggest swell, but with clean, glassy conditions and a long-period SW groundswell, that’s gonna be the most fun waves of the whole run. The water is sittin’ at 81°F, which is about normal for this time of year.

Crowds can show up at Wanjapu, so on that Sunday morning, go early.

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.
