The Lowdown
Alright, grab a seat. Rusty here, and I’ve been staring at the charts for Adraga. Honestly, it’s a bit of a tough watch for the next week and a half. We’ve got a long, dry spell of lumpy, cross-onshore conditions that’ll have you wondering why you bothered dragging the board out. The first real glimmer of hope doesn’t show up until Sunday morning, the 13th of September – and that’s a long way off.
For the first ten days, it’s a story of fresh wind and messy surf. The wind is mostly from the north or north-northwest, slapping the surface at 18 to 25 mph, with swell heights bouncing between 3 ft and 7 ft, but it’s all short-period, wind-driven junk. The combined energy gets up there – over 700 at times – but it’s a rough, angry energy, not the kind you want to paddle into. The water is sitting at 68°, which is about normal for this time of year. Most of these sessions are a hard pass.
Then we get to Sunday, the 13th. That’s the standout. The morning looks like a whole different ocean. The wind drops to a whisper – a glassy 3 mph from the west-northwest – and the swell is a proper groundswell coming out of the northwest at 3 ft, with a very long period of 16 seconds. That’s a clean, lined-up wave with heaps of energy behind it (combined energy of 576). The optimum direction for Adraga is west-northwest, and a northwest swell is close enough to get the reefs and points working nicely. Expect clean, glassy conditions. The afternoon gets a bit of a cross-onshore breeze, and the swell jumps to 4 ft, but the morning session is the one to aim for.
Following that, Monday the 14th is a bit of a letdown with a light cross-shore breeze, but the swell is still there at 4 ft from the northwest. It’s surfable, but not as clean as Sunday. After that, the wind turns onshore again and the run of average to poor conditions takes over for the rest of the forecast period.
So, if you’ve got patience, keep your eyes on that Sunday the 13th. It’s the only real window of quality in the whole outlook. The rest is a waiting game.
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.
