The Lowdown
Alright, this is Rusty. Let’s talk about what’s on offer at Adraga over the next couple of weeks.
Right now, we’re looking at a pretty grim stretch to start. Adraga is getting hammered by strong cross-shore and onshore winds for days on end, with messy, chopped-out conditions. The water is sitting at 67°, which is a bit colder than normal for this time of year.
Monday the 24th is a write-off. Solid 10ft swell from the WSW, but with 25 mph cross-winds and rain showers, it’s just nasty. The combined energy is strong (1059) but that doesn’t matter when it’s all cross-chop. The afternoon isn’t much better.
Tuesday the 25th morning is actually the only decent window in the near future. Glassy conditions, light winds from the SSW, with a small 5ft swell from the WNW at 7 seconds. The combined energy is weak (189) but for a clean, small-wave session, it’s the best you’ll get for a while. The crowd factor is "sometimes", so you might have company. That’s your only real chance for the next few days.
From Wednesday the 26th through the rest of the first week and well into the following week, it’s one long stretch of cross-onshore winds, moderate to strong breezes, and lumpy, choppy surf. We’re talking a solid 7 to 8 days of poor to marginal conditions. There are some bigger pulses – like Friday the 28th with 10ft WNW swell and strong energy (1791) in the morning, or Saturday September 5th with 7ft NW swell and strong energy (1441) – but all are ruined by the wind direction. Not worth paddling out.
The real standout comes on Monday September 7th. This is the one. Morning brings a 10ft swell from the WNW with a very long 17-second period, and offshore light winds from the NNW. The combined energy is massive (6506). This has all the makings of a proper groundswell hitting Adraga. Now, with that kind of long-period energy, the waves will have serious power, and on a beach-and-reef setup like this, it’s going to be for experienced surfers only. It’s a promising call at this range, but definitely one to watch. The afternoon holds similar size and quality, just with a slight cross-on wind shift.
Before that, there’s basically nothing worth suiting up for. A long, frustrating gap. But that September 7th window? That’s the one that could make the wait worthwhile.
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.
