The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for Adraga over the next couple of weeks.
To be straight with you, the outlook for Adraga is a tough one. Right from the start on August 5th and running all the way through to the end of the forecast window, the conditions are persistently poor. We're looking at a solid 16-day stretch where the surf quality just isn't there for a good paddle. The wind is almost always coming from the north or north-northwest, and it's blowing cross-onshore at moderate to strong speeds, keeping the ocean lumpy, choppy, and messy. The swell is mostly under 5 ft, and the wave energy is generally on the weaker side, but none of it matters when the wind is working against you.
There is no real standout, no hidden gem hiding in this data. Every single session from the morning of the 5th through the afternoon of the 20th of August is rated as poor surf. The wind is just too strong and from the wrong angle to make any of these small, short-period swells worthwhile. It's a full blank run, which for this exposed beach-and-reef setup, isn't too unusual when the winds lock in from the north like this. The water temp is around 67°, which is about average for this time of year, but that's small comfort when you're staring at choppy, blown-out lines.
Forget the paddle; with that consistent 12 to 25 mph cross-onshore wind and the 1 to 5 ft waves, this setup is a lot more interesting for the kite surfers than us. There's plenty of energy there for them, but for a surfer looking for a clean face, it's a no-go.
Keep the board in the bag and wait for the forecast to shift. Things can't stay this poor forever.
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.
