The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next stretch.
Right off the bat, I gotta level with you – this is a tough one. The forecast is a long grind of messy, cross-onshore wind and lumpy conditions. The energy is there, but the quality is just not. For the first week and a half, we’re staring at a whole lot of “poor surf conditions” with only a few mornings that are barely worth a paddle. The wind is almost always from the SSW or SW, blowing right across the wave, and that’s keeping the surface choppy and frustrating.
The water temp is about average for the time of year, so no shock there, but that won’t help the shape.
The one true standout – and I mean the only highlight in this whole 16-day run – is Friday, the 4th of September. On the morning of the 4th, we get a complete reset. The wind drops to near nothing, glassy conditions. The swell is a clean 3 ft from the SSW with a period of 13 seconds, giving it some decent groundswell feel. The combined energy is moderate (548). That’s the window. If you’re waiting for a reason to get wet, that’s it. It’s over a week away, so keep an eye on it, but it looks promising.
Before that? There’s nothing you’d drive for. The whole period from 23 August through to the 3rd of September is a no-go. The wind is relentless, and the swell is either too choppy, too lumpy, or just plain messy. There are a few mornings with light breezes, like on the 29th and 30th of August, with 3 ft swell from the SSW, but the cross-on wind still ruins the surface. Not worth the effort.
After the 4th, the wind picks right back up, and we’re back to the same story. The 5th and 6th of September have cleaner mornings but the swell drops off and the wind gets up again by afternoon.
So, bottom line: if you’re after a good surf, hold out for the morning of the 4th of September at Arugam Bay. It’s the only time the stars align. The rest of the period is a write-off. Don’t waste your petrol.
Rusty.

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