The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Adraga over the next couple of weeks. It’s a mixed bag, and to be honest, we’ve got a rough start ahead.
Right now, we’re looking at a long stretch of poor conditions. The surfable waves we do get are plagued by strong cross-onshore winds and messy chop. The water temperature is running about average for this time of year, so no surprises there.
The first real hope shows up on Tuesday morning, August 25th. The wind drops right out – glassy conditions, zero wind. The swell is small, only 4ft from the west, with a short period of 7 seconds. The combined energy is weak, just (164). This isn’t a standout in any way, but glassy conditions on a beach and reef set-up like Adraga mean the waves will be clean and user-friendly. It’s a window for a cruisey session when the rest of the week is blown out.
After that, we’re back into a relentless pattern of north and north-northwest winds, pumping 15 to 25 mph straight onshore, which ruins the face of every wave. This lasts for days, all the way through until early September. The swell size builds over this time, from around 5ft to over 8ft, and the swell period stretches out to 11 or 12 seconds – a proper long-period groundswell. The wave energy gets strong, hitting (1545) on Saturday, September 5th. But it doesn’t matter how much energy is out there – with those winds, it’s a washing machine. This setup, with significant swell and strong onshore wind, looks far more interesting for kite surfing than paddle surfing. You’d be battling a strong cross-onshore and messy conditions. It’s expert-only territory if you even try, with swell over 8ft. The long period (11-12 seconds) would normally mean good shape, but the wind kills it completely for Adraga.
There’s no true standout session here. The Tuesday morning, August 25th glass-off is your only real shot at something clean, but the swell is small and weak. The whole second week is a write-off for any quality waves at this break.
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.
