The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Arna Plage.

The next couple of weeks are a bit of a mixed bag. We’ve got a slow start, but the second week is shaping up with some real potential, especially if you’re keen on clean conditions. The water temperature is sitting at 75° right now, which is much warmer than normal for this time of year—so you can leave the thick wetsuit at home.

First up, Thursday the 27th and Friday the 28th are a write-off. The swell is tiny at 1 ft to 3 ft, short period, and the wind is all over the place, making for poor surf. Not worth paddling out.

Saturday the 29th sees a bump in size to 6 ft, but the wind is cross or cross-on, so it’s messy. The energy is moderate (464), but the conditions just aren’t there.

Sunday the 30th is the first real bright spot. Sunday morning brings a clean 5 ft swell from the WNW with a 8-second period, and offshore winds from the ESE at 5 km/h. The water’s glassy, the combined energy is moderate (455), and it’s your best bet for a fun session early on. The morning is the window—by afternoon, it’s back to choppy cross-on.

Monday the 31st sees the swell hold at 5 ft to 6 ft, but the wind is onshore, so it’s going to be bumpy and tough to enjoy. Tuesday the 1st of September morning is clean again, with a 5 ft WNW swell, cross-off breeze from the NE, and clean conditions. The energy is moderate (386). That’s another solid window.

From Wednesday the 2nd through Friday the 4th, the swell drops right off—down to 2 ft to 3 ft. The energy is weak (60 to 99). Winds are light offshore or glassy on the mornings, but there’s just not enough swell to get excited about. Friday the 4th morning is glassy with 3 ft, surfable but very ordinary.

Now here’s the standout. Saturday the 5th of September morning is the pick of the whole outlook. You’ve got a 5 ft swell from the NW, a long 12-second period, and offshore winds from the ESE. The combined energy is strong (590), and it’s clean. That’s a proper groundswell with good shape—perfect for a long session. The afternoon gets chopped by onshore wind, so get in early.

Sunday the 6th morning is also good, with a 5 ft NW swell, 11-second period, and glassy conditions from the SSE. The energy is strong (496). Another clean, fun morning.

Monday the 7th is a write-off again with onshore wind and small swell. Then Tuesday the 8th of September morning is another standout. Clean 5 ft NW swell with 11-second period, offshore breeze from the ESE, and strong energy (630). That’s big, clean, and powerful—definitely the best of the second week.

Wednesday the 9th and Thursday the 10th are marginal with onshore or cross-shore wind and messy conditions. The swell gets up to 7 ft on Thursday the 10th morning, but with cross-shore wind and a 9-second period, it’s not going to be clean. The energy is strong (727), but the wind kills it.

Friday the 11th of September morning is a nice finish—clean 4 ft WNW swell, 11-second period, and a light cross-off breeze from the E. Energy is moderate (302). A good way to wrap things up.

Overall, the best windows are Sunday the 30th morning, Tuesday the 1st morning, Saturday the 5th morning, Sunday the 6th morning, and Tuesday the 8th morning. Saturday the 5th and Tuesday the 8th are the real standouts—clean, long-period groundswell with strong energy. Get out there early before the onshore wind messes it up.

Rusty.

Information about the Arna Plage Surf forecast

The above surf forecast table for Arna Plage provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Arna Plage can be found by selecting the local surf guide option on the grey menu. Our Arna Plage 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 (Arna Plage) 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 Arna Plage 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.
