The Lowdown

Alright folks, Rusty here. Let’s have a look at what Sosanji has in store. Straight up, it’s a tough stretch. We’ve got a big, onshore-plagued start with a stormy vibe, and then a long wait until the second week for any real glimmer of hope. There's a gap of several days with nothing worth paddling out for before we get to the one true standout.

The first few days, from Saturday the 8th through to Sunday the 9th, are a write-off. We’re seeing a solid 10 ft swell on Saturday morning, but it’s coming with a strong 22 mph easterly wind blowing directly onshore. The combined energy is a massive 2610 (moderate to strong), but with that wind, it’s just a washing machine. Poor surf conditions all around.

Monday the 10th is a bit of a let-down too. The swell drops back, but it’s still onshore. The combined energy is down to around 1112 (moderate), but it’s onshore and the surf is only marginal at best.

Now, Tuesday the 11th is the first time we get a little whisper of something better. Early morning, the wind goes completely glassy (0 mph from the NE). The swell is a modest 4 ft from the east with a nice long 12-second period. Combined energy is 623 (moderate). This is the first time we get a “very good surf conditions” note. However, the waves are small, and the long period groundswell can make beach breaks a bit fat. It’s a session for a log or a longboard, and it’s clean. This is about the best we see until the second week.

But then it goes quiet again. From Wednesday the 12th until Saturday the 15th, it’s either onshore, cross-onshore, or just too small. There is a gap of no real recommendations for several days here. The surf is poor, or marginal at best. The combined energy drops into the weak range, hitting 198 and 160 (weak).

Sunday the 16th is the big one. That’s over a week away, so keep your fingers crossed. In the morning, we get a clean, glassy start again (0 mph from the NE). Swell picks up to a proper 6 ft from the east, with a long 12-second period. The combined energy jumps back up to 833 (moderate). The setup is “very good surf conditions”. That’s the standout of the entire run. It’s a solid, clean size with good energy. It’s a bit much for a beginner at 6 ft, but for intermediate and above, that’s the window.

After that, Monday the 17th is okay but cross-onshore, and then it’s back to small and messy for the rest of the run. Thursday the 20th shows a pulse of 5 ft from the ESE, but it’s a short period at 7 seconds and onshore, so not great. The combined energy of 316 (weak) tells the story.

So to sum it up: the best bet by far is Tuesday morning the 11th for a clean, small-wave session, and then keep an eye on Sunday the 16th for the best swell of the whole period, if that glassy wind holds. The rest is a battle with the wind. The water temp is a warm 84°, which is about normal for the time of year here.

Rusty.

Information about the Sosanji Surf forecast

The above surf forecast table for Sosanji provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sosanji can be found by selecting the local surf guide option on the grey menu. Our Sosanji 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 (Sosanji) 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 Sosanji 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.
