The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer at Tenia over the next couple of weeks. I’ll be straight with you – this forecast is a bit of a mixed bag. We’ve got some serious energy coming through, but the wind is gonna be a pain for a lot of it.

Right now, we’re looking at a pretty quiet start. The first real chance to get wet doesn’t come until Thursday morning, the 20th of August. The swell is a small 4ft from the S with a short period of 8 seconds, and the combined wave energy is pretty weak (385). It’s only marginal, but with a light breeze, it might be worth a look for the die-hards.

The rest of that week is a struggle. The wind is mostly cross or cross-offshore from the ESE, but it’s too strong for clean waves. The surf quality is poor. You’ll see a bit of a bump on Saturday morning, the 22nd, with 5ft from the SE, but it’s still a marginal call. The energy is moderate (599) but the cross-shore wind is messy.

Now, here’s a glimmer of hope. Sunday afternoon, the 23rd of August, things finally start to line up. We’ve got a 5ft swell from the SE and only a slight air movement. The wind is almost glassy, turning cross-offshore, and the forecast is calling for “good surf conditions.” The energy is moderate (408). This is easily the best bet in the first week – the waves won’t be huge, but they should be clean and fun. The water temp is about 73° F, which is bang on average for the time of year, so no surprises there.

After that, we fall into a long, quiet gap. The next few days into the end of August are all marginal or poor, with very small swell and onshore winds. It’s a real lull. You’d be better off waiting.

Then, things get interesting, but only for the experts. On Monday, the 31st of August, the swell starts to ramp up. By Monday afternoon, we’re looking at a massive 12ft SSW groundswell with a long period of 17 seconds. The combined energy is through the roof (7733), which is very strong. The wind is a fresh cross-shore, so it’s going to be lumpy. The forecast says the swell is too big for this break. At that size, with heavy 12ft sets, this is strictly for seasoned pros in the water. The long period will make it powerful and walled up, better suited for a reef or point, but Tenia is a reef, so it has that going for it. The crowds could be an issue, as it gets “sometimes” busy. This is the standout, but it’s a dangerous one.

That big swell hangs around into Tuesday morning, the 1st of September, with another 12ft from the SSW. The energy is still massive (5063). Again, too big for a casual session. The wind is a moderate cross-shore, so it’s a bit cleaner than Monday, but it’s still a heavy, expert-only day.

After that, the swell drops back down, but the wind gets nasty again. The rest of the forecast is a write-off with strong winds and poor conditions.

So, to wrap it up: the best clean, fun waves for everyone are on Sunday afternoon, the 23rd of August. For the big-wave chargers, the 31st of August and 1st of September offer massive, powerful swell, but it’s a serious, expert-only affair. Don’t bother with the rest.

Rusty.

Information about the Tenia Surf forecast

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

Tenia is 54 km (34 miles) from Thio. If you plan a holiday in New Caledonia, look for hotels and other accommodation in Thio. Thio has rooms for a wide range of budgets as well as car hire and transport links.
