The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for Arugam Bay over the next couple of weeks.

Right off the bat, I gotta be straight with you – the first few days are a write-off. Sunday the 16th through Monday the 17th, we’ve got choppy, cross-onshore winds messing everything up. The swell is there, but it’s ugly. There’s a bit of a wait for the magic to line up.

The real standout in this whole forecast is the morning of Tuesday the 18th of August. The stars align for a session. The wind goes glassy – dead calm – and the swell is a solid 6ft from the SSW, with a super long period of 19 seconds. That’s proper groundswell energy. The combined energy is pumping at 2411 (strong to very strong wave energy). This is a day for experienced surfers only, as it’s gonna be powerful. The water is warm, about 83°, which is pretty average for the time of year, so no surprises there. That Arugam Bay point is going to be absolutely firing, with that optimum SE direction matching up nicely. Just keep in mind, with that long period, the waves might stand up and wall up perfectly on the point, but it could be a bit too straight for the beach breaks. Crowds are possible here, so get out early.

The rest of the week is a bit of a mixed bag. Wednesday the 19th and Thursday the 20th mornings have some clean-ish conditions with light cross-onshore breezes, but the surf quality is marked as marginal. The swell holds around 6ft with a long period, so there’s power, but the wind isn’t perfect. You could get some fun ones if you pick your tide right.

After that, the wind turns into a bit of a headache. From Friday the 21st right through to the end of the month, we’re mostly looking at moderate to fresh cross-onshore winds, turning the ocean into a lumpy mess. There are a few windows of lighter wind, like the morning of Saturday the 22nd, where you’ve got a 8ft SSW swell at 17 seconds, but it’s described as marginal. For a surfer, that means it’s not the clean, groomed stuff you want.

The only other real glimmer in the second week is the morning of Wednesday the 26th of August. We get another glassy window, just like the 18th. The swell is a bit smaller at 3ft, but it’s a long 18-second period from the SSW. The energy is lower at 732 (moderate), but with glassy conditions, it’ll be clean and fun for a longboard or a fish. It’s a very different vibe to the 18th – more of a cruiser’s session than a charger’s day.

So, to sum it up: the absolute best days on offer are the morning of Tuesday the 18th of August for the big, powerful, glassy groundswell, and the morning of Wednesday the 26th of August for a cleaner, smaller, more forgiving session. The gaps in between are filled with wind-affected, choppy surf. Hang tight.

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.
