Table - best surf conditions forecast for Wanjapu over the next 16 days.


Alright, Rusty here. Let’s have a look at what’s on the table for Wanjapu over the next few weeks.

First up, the water’s sitting at 81°, which is about average for this time of year, so nothing weird going on there.

Right now, we’re looking at a bit of a slow start. Saturday the 11th kicks off with a 6ft SW swell and a 15-second period, but the wind is cross-on from the south at 3 mph, and the wave comment calls it marginal. The combined swell energy is solid at 1286, but the conditions aren’t doing it any favours. Sunday the 12th morning is where it gets interesting – glassy conditions, a 4ft SW swell with a 14-second period, and the wave comment says “expect very good surf conditions.” That’s a clean, lined-up reef break setup, and for a spot that’s consistent and exposed to the SW, this is the standout of the first week. The energy drops to 578, but with glass, it’ll be pure. Crowds are possible at Wanjapu, so keep an eye out.

Monday the 13th morning is also glassy, but the swell has dropped to 3ft with a 13-second period – still clean, but smaller. After that, the wind turns cross or onshore for most of the next week, and we get a stretch of “marginal” days with bumpy conditions.

Now, looking ahead to the second week, there’s a serious pulse building. Monday the 20th morning sees an 8ft SSW swell with a 17-second period, and the combined energy jumps to 3876 – that’s strong energy. The wind is just a light cross from the SE at 6 mph, but the wave comment is still calling it marginal. That’s a powerful, long-period groundswell that will be breaking straight at a reef, so it’s going to be big and lined up – expert-only territory at over 8ft. This is a real standout for the crew who can handle it.

Then Tuesday the 21st morning is a beauty – glassy conditions again, with a 7ft SSW swell and a 15-second period. The wave comment says “excellent surf conditions for experienced surfers,” and the combined energy is 1762. With glass and that size, this is the other top pick. It’s a long-range promise, so keep the fingers crossed, but it looks like a ripper.

After that, the swell fades into the 22nd and beyond, with smaller waves and mostly cross or onshore wind. The last few days of the month drop to under 3ft, so it’ll be quiet.

Overall, the best windows are Sunday the 12th morning for clean, manageable waves, and then the Monday 20th and Tuesday 21st mornings for the bigger, more powerful stuff – but that’s strictly for the experienced. If you’re not up for the heavy juice, hit it on the 12th.

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.
