The Lowdown

Alright, I’m lookin’ at the full 16-day window from now, and I gotta be straight with you: it’s a tough run to get excited about. The only real bright spot is Tuesday the 18th – that’s your one chance this week. After that, the wind just turns on us and it’s a long, messy stretch for a long time. Let’s get into it.

First up, Tuesday morning the 18th at Adraga, and this is the standout. It’s a beach and reef setup, exposed to the WNW swell. We’ve got a clean 5 ft swell from the NNW, with a period of 8 seconds, which is a bit short, but it’s workable. The wind is light out of the S at 9 mph, blowing cross-offshore, so the faces will be pretty clean. The combined energy is moderate at 255, so there’s some push. Water temp is sitting at 69°, which is about average for the time of year here. The morning session is the one to hit – it’s the only time in the whole outlook where the quality is genuine. Crowds are *sometimes* an issue here, so if you can get out early, you’ll have a better shot.

Tuesday afternoon sees the wind pick up a little from the SSW, still cross-off, but the tide or conditions drop the quality a notch. It’s marginal.

Wednesday the 19th, the swell drops to 3 ft from the NNW, period just 7 seconds. The morning is surfable but very ordinary, with a light S wind. The afternoon turns cross-on from the WSW, and it’s poor. Not worth paddling for.

From Thursday the 20th all the way through to the end of the month, we’re in a long, frustrating gap. The wind swings hard from the NNW, blowing 16 to 25 mph, cross-on or onshore, and the swell gets bigger but it’s completely blown out. On the 21st and 22nd, the swell hits 5 ft to 8 ft, but with that strong, messy wind, it’s a total write-off. The energy climbs into the hundreds, even over 1000 on the 23rd, but it’s all for nothing – it’s a kitesurfer’s paradise, not a surfer’s.

The last few days of the month and into early September stay poor. The wind stays onshore or cross-on, with swell around 3 ft to 6 ft, but the quality is just not there. The only flicker of hope is Monday the 31st of August in the morning – we get a glassy 3 ft from the WNW with a period of 10 seconds, and a light NE breeze at 3 mph. The energy is moderate at 181. It’s listed as “surfable but very ordinary,” so it’s a long shot, but if you’re desperate, that’s the only other window. The rest of that day and into September is poor again.

So, bottom line: Tuesday morning the 18th is your best bet. After that, it’s a long, windy wait. Don’t hold your breath for anything clean until maybe that glassy window on the 31st. Stay tuned and hope the forecasts change.

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.
