The Lowdown
Alright crews, Rusty here again, giving you the lowdown in good old feet and miles.
For Wednesday morning, we’ve got a tiny 3ft swell from the NNW, and it’s actually glassy with light S winds – surfable but nothing special. Water temp is about average for the season. By the afternoon, it turns messy with a cross-on W breeze. Thursday is a write-off with only 2ft and onshore winds. Friday pumps up to 6 to 7ft from the NNW, but paired with a 22 mph cross-on wind, it’s all bumpy and blown – not worth your time.
Actually, the whole stretch from Saturday the 22nd to Sunday the 30th is a tough watch. Swell runs from 4ft up to 8ft on Saturday, but the wind is almost always a strong cross-onshore, making the ocean lumpy and poor for surfing. The combined energy numbers go from moderate to strong (like 857 on Sunday morn), but without good wind, the quality is zero. Monday the 25th does have a smaller 3ft swell, but it’s still a bit choppy – nothing to rush for.
Now, here’s the only real standout: Thursday morning, September 3rd. That morning we’ve got a clean 5ft NW swell with a 9-second period and dead calm wind from the west – flat-out glassy at Adraga. Energy is moderate at 404. That’s your day. Everything else is either too small, too windy, or just plain messy. For the big swells over 8ft in early September, the cross-on wind ruins it for all but the hardcore. Beginners should stay out when it’s over 5ft, which is most of this run.
A long gap of poor surf is pretty normal for the area, but keep an eye on the forecasts. For now, that Thursday morning in September is the only one I’d bet on.
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.
