The Lowdown
Alright folks, Rusty here. Let's look at what Tenia has cooking for the next couple of weeks.
The first few days are nothing to write home about. You get a few rideable waves on Thursday the 20th with a 5ft S swell and a cross-off breeze keeping it clean, but the energy is only moderate (811). It's a so-so start.
Friday the 21st is a total loss. Strong cross-shore winds and a lumpy mess. Skip it. The weekend is a gamble. Saturday the 22nd has some size, 5ft to 6ft from the SE with clean conditions in the afternoon, but still just a marginal call. Sunday morning is tiny, but the afternoon shapes up alright with a light offshore breeze and a clean 4ft wave.
Here's where it gets proper. The standout window starts Tuesday the 25th. A serious, long-period groundswell from the SSW rolls in. Tuesday morning sees 6ft waves with a 16-second period and massive energy (1489). It's powerful. Tuesday afternoon is even better for size, hitting 6ft with a 15-second period and a clean surface. This is the biggest, most powerful swell of the whole outlook.
Wednesday the 26th afternoon is a top contender. The wind goes light offshore from the NNE, grooming that 5ft, 14-second SSW groundswell. It will be clean, lined-up, and offering proper shaped waves.
But the absolute best session? Without a doubt, Thursday the 27th morning. The ocean goes glassy – flat calm with a light southerly. You've got a clean 4ft, 15-second SSW groundswell. For a reef break like Tenia, that combo of glassy water and long-period energy is a dream. It'll be smooth, peeling waves for the experienced guys.
After that, the surf fades. The following week is a bust with small waves and strong cross-shore winds. There's a flash of 5ft on Sunday the 30th, but the onshore wind and short period (7 seconds) make it choppy and unrideable.
So the call is clear: Thursday the 27th morning is the gold watch. Get out there for that glassy, long-period SSW swell. For more power, hit Tuesday the 25th afternoon or Wednesday the 26th afternoon. Everything else is a washout.
Stay frothy,
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.
