The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming up for Tenia.
The next couple of weeks are a bit of a mixed bag, and honestly, the start is pretty ugly. We’ve got a big pulse of swell hitting early on the 18th, but the wind is just howling from the SE at 25 mph, creating messy, cross-chop conditions. That 10ft SSE swell has a moderate period of 12 seconds, and the combined wave energy is strong at 5421, but the wind is so bad that it’s not worth paddling out unless you want a fight. The water temp is sitting at 73°, about average for this time of year. The rest of that first week into the 19th and 20th is a struggle, with onshore winds and lumpy surf, though the morning of the 20th does see a dip in wind to just 3 mph, but the swell is small and weak with only 772 energy.
Now, here’s where it gets interesting. If you can wait, the afternoon of Monday the 24th is the standout of the entire forecast. We’ve got a very clean, glassy day with a long-period groundswell from the SSW at 20 seconds. The swell height is only 2ft, but the period is so long that it’ll wrap in beautifully at this reef break (Tenia). The winds are virtually nothing from the east, and the wave energy is a moderate 442. This is a session for the connoisseur – a clean, lined-up wave, perfect for an intermediate surfer.
The morning of Tuesday the 25th also looks promising, with a bigger 5ft SSW swell, also with a long 15-second period, and light winds, giving a combined energy of 1076. It’s a bit more size, but still manageable and clean. After that, the second week fades fast. Swell drops, winds turn cross or onshore again, and by the end of August and into September, it’s mostly flat and choppy. The long-range blip on Wednesday the 2nd of September shows a 5ft SW swell with a 12-second period, but the cross-shore wind from the SE kills the quality.
Overall, the best bet is to pencil in Monday the 24th for a clean, long-period session at Tenia. The 25th morning is a close second for a bit more size. The first week is a write-off for any decent paddling.

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.
