Alright, Rusty here, and I’ve got the lowdown on the waves coming our way for Arugam Bay over the next couple of weeks. Things start off promising but get a bit ugly for a while, so you gotta pick your moments.
To kick it off, the water temp is sitting about where you’d expect for this time of year, so no surprises there. Just standard tropical vibes.
The first real window to get excited about is this Sunday morning, July 5th. We’ve got a clean 5ft swell pushing in from the SSW with a short, punchy 6-second period. The energy is moderate (430) but the key here is that it’s glassy—dead flat wind, not a breath of air. That’s going to make Arugam Bay look real pretty, with smooth, peeling lines. It’s a point break, it handles a south swell well even though the optimum is from the SE, and it’s fairly consistent. Just a heads up, it can get a little busy here sometimes, but early morning you’ll be fine.
Monday morning, July 6th, is where it gets really special. The swell drops to 2ft, but the period jumps to a very long 16 seconds from the SSW. That’s proper groundswell energy, and the combined energy is solid (517). With glassy conditions again, this is going to be some of the best small-wave surfing you’ll see—crisp, long walls, easy paddling. You could easily call this the standout session of the whole forecast.
The pattern continues Tuesday morning, July 7th, with another glassy morning and a tiny 2ft, 16-second swell. It’s super clean again, though maybe a little small for some. Still, if you’re on a log or a fish, you’ll be having a ball.
Now here’s the thing—come Tuesday afternoon the wind swings cross-onshore and the swell bumps up to 6ft with a short period, and it gets messy. From there on out, it’s a long stretch of poor conditions. The next couple of weeks are dominated by moderate to fresh cross-onshore winds from the SSW and SW, and while there’s plenty of swell (some days pushing 8ft), the quality just isn’t there. It’s going to be choppy, lumpy, and hard work. That 8ft on Wednesday afternoon, July 15th, with a 30 km/h cross-onshore wind? That’s more of a kitesurfing show than a paddle-in session.
To sum it up: the first three mornings (Sunday the 5th, Monday the 6th, and Tuesday the 7th of July) are your gold. Get out there early for glassy conditions and long-period groundswell. After that, the wind ruins it, and we’re looking at a blank run of poor surf that stretches all the way through to the end of the forecast on July 20th.
Stay sharp and get on it early.

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.
