The Lowdown
Rusty here, let’s look at what Tenia has in store for us over the next couple of weeks.
The first bit is a total bummer for paddle surfing. From the 17th all the way until the 23rd, it's nothing but messy cross-shore winds and lumpy conditions. We’re talking strong breezes (25 mph on the Monday) and a real chop. There's plenty of swell out there, with some serious energy readings, but the wind is just shredding any chance of a clean wave. This is kite-surfing territory for sure. That’s a solid week of no good.
Things finally turn around on Thursday the 24th. A nice, long-period SSW groundswell shows up, and the wind starts to cooperate. Tuesday the 25th (morning) is the absolute pick of the forecast. We’re looking at a clean 4.6ft of SSW swell with a 15-second period, and the wind is dead calm and glassy. That’s about as perfect as it gets for a reef like Tenia. The energy is solid at 914, so the waves will have some real punch. The water is 72.9°F, right about average for this time of year.
Wednesday the 26th keeps the good vibes going with more SSW swell around 4.9ft to 5.2ft and that nice long period, but the wind shifts a little cross-on, so it won't be as clean as Tuesday. After that, as we head into the end of the month and September, the swell fades and the winds get flukey again. A few mornings might offer some waist-high waves, but nothing to write home about.
So, the one to aim for is Tuesday the 25th (morning) at Tenia. It has the size, the right direction (SSW), that beautiful long-period energy, and the wind is glassy as can be. It’s a fairly consistent spot, so you’ll get waves, but expect a few other people to have the same idea. That’s your window.

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.
