The Lowdown
Alright mate, let’s talk Adraga. It’s been a rough patch of slop lately with a west to northwesterly swell coming in all messed up. The water temp is about what you’d expect for now, nothing crazy.
We kick off with two days you can just skip. Sunday the 23rd and Monday the 24th are trash – thunderstorms, heavy rain, and strong winds ruining a 6 ft to 8 ft swell. The wave energy is moderate (795 to 715 in the combined energy) but it’s all cross-off and cross-onshore junk.
Then on Tuesday the 25th morning, there’s a little break in the clouds. The wind goes glassy, just 3 mph from the SSE. Swell drops to 5 ft from the west at a short 7 seconds, with a weak combined energy of 208, but it’s clean. Not big, not powerful, but it’ll be smooth. That afternoon, the cross-shore wind comes back and it’s over.
After that, it’s a long, rough haul. From Wednesday the 26th all the way to September 7th, it’s mostly poor conditions. The wind is onshore or cross-onshore every day, from light to fresh to strong breezes. Swell sizes bounce between 2 ft and 7 ft, mostly from the NW to NNW, but periods are short – 5 to 10 seconds – and it’s all choppy, lumpy, or messy. Combined energy numbers go from as low as 53 up to 1028, but with the wind howling, none of it’s any good for surfing. A few sessions are marked “unknown” for wind state, but they’re still rated poor.
The one and only standout is that Tuesday morning (25th August) with the glassy conditions. It’s a tiny window, but if you’re keen, a clean 5 ft west swell with no wind is as good as it gets in this run. For the rest of the 16 days… honestly, this looks more like a kiteboarding forecast than a surf forecast, especially on the bigger, windier days. It’s a long, dry spell, nearly two weeks of nothing worth paddling for. But hey, forecasts change, and it won’t stay dead forever.

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.
