The Lowdown
Alright, listen up. It’s a slow start, but a promising finish. Water temp is a nice 84°, slightly warmer than the average, which is a bonus. We've got some small, choppy surf on tap for the first few days, with wind blowing cross or cross-on. Not great.
The morning of the 14th is the first time we get a break. The wind drops to glassy and the surf cleans up. You’ve got a little over three and a half feet of swell from the SSE at 11 second intervals. It’s not big, but it’s clean, and Arugam Bay (Eastern Province) will be the place to be. Energy is moderate, 802, so there’s a bit of push.
The morning of the 15th is also workable. Clean conditions with a cross-offshore breeze, and the swell holds at 4ft. Energy drops a bit to 546, but clean beats mushy every day. The afternoon turns onshore, so get it in the morning.
Then the 16th is another one. The morning is glassy with the swell easing slightly to 3ft. Energy is still moderate at 516, and the afternoon stays glassy with a touch more energy at 558. Small, clean, fun waves.
After that, the energy drops off for a few days. But then it gets interesting. Around the 18th, longer period SSW groundswell shows up. The swell bumps up to 6ft with a period of 19 seconds, and the energy jumps way up to 2377. The morning of the 18th is glassy, and this is going to be a standout. That kind of period on the point is a thing of beauty. It’s going to be an excellent paddle out.
The 19th morning is another big one. Similar size at 7ft, also from the SSW, with a 17 second period. The energy is strong at 2703 and the wind is dead glassy. This is bigger and more powerful, so it's for the experienced crew. Beginners should sit this one out, but for the rest of you, this is the session. It's the pick of the run.
After that, the winds get messy again, but the swell hangs on. The 23rd morning looks clean with a light cross-offshore breeze and the swell easing to 5ft. Less energy by then, but still good.
So, the best on offer is the morning of the 19th. The combination of size, period, and clean conditions is right up there. The morning of the 18th is a very close second.
Patience will pay off this fortnight.

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.
