The Lowdown
Hey, it's Rusty. Let’s be straight about Adraga.
It’s gonna be a tough stretch. For the first few days – from the 20th through to the morning of the 23rd – you can leave the board in the car. Tiny surf or solid-size swell absolutely wrecked by cross-onshore winds. Nothing doing.
Sunday the 23rd morning is the only real window. We get a clean cross-offshore breeze from the South at 15 mph, and a head-high-plus swell of about 6 ft rolling in from the West with an 11-second period, and the ocean’s got some moderate energy behind it. It’s still touch-and-go, but that’s your best bet across the whole 16 days.
After that, it’s back to the grind. Day after day of fresh onshore winds, lumpy conditions, and a mix of direction that just doesn’t line up. The standout remains that Sunday 23rd morning. The offshore wind will clean up the break and make the most of that West swell. Water temp at the start is pretty normal for this time of year.
If you’re not out there on that Sunday morning, you might as well save your energy. The rest of the period looks better for kite surfing than for a clean paddle session.
Rusty.

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