The Lowdown

Alright, Rusty here again, getting a handle on the surf at Inside Reef (Hikkaduwa) for the next couple of weeks. Gotta be honest, it’s a tough stretch. The best I can say is there are a few sessions that might be more interesting than the rest, but nothing’s screaming “paddle out.”

The whole pattern is driven by a strong SSW groundswell that’s packing a serious punch, with energy readings from (1537) to (3723). That’s a lot of power from the deep south, and the period is long – 15 to 19 seconds – proper groundswell. For a reef, that’s good for shape, but the wind is the problem. It’s almost always blowing onshore or cross-onshore from the west, which messes up the surface. Water temp is 83°, which is about average for the year.

Let’s run through it. This Saturday afternoon, August 8th, we’ve got a 4ft SSW swell with a 15-second period, but the wind is a stiff 15 mph from the west. That’s a no-go – wind-affected and choppy.

Sunday the 9th morning has a smaller 3ft S swell with a very long 17-second period, but the wind is still on. The afternoon bumps up to 6ft S, still long period, but again, the wind ruins it. Same for Monday: 4ft and then 6ft, but it’s rough.

Tuesday the 11th morning has a 4ft S swell with a 19-second period – about as long as it gets. The reef should handle that nicely, but the wind is straight on. It’s just not clean.

From Thursday the 13th onward, the wind shifts to the WNW and goes cross-onshore, with swell from the SSE around 3ft to 4ft and a shorter 11-second period. The energy drops below 1000, and conditions are described as choppy. This stretch from the 13th through the 17th is flat and messy – nothing to get excited about.

Now, here’s the best of a bad bunch: around August 17th, Monday afternoon, we see a 3ft SSW swell with a 21-second period. That’s an incredibly long period, so the sets will be powerful but spaced out, and at a reef like Inside Reef, that could produce some nice, walled-up waves. The combined energy is (1489), so moderate. But again, the wind is cross-onshore from the west.

The 18th and 19th of August have the biggest swell – 7ft to 8ft from the SSW, with periods around 17-19 seconds. The energy is very strong (3538 to 3723). That’s a big, powerful groundswell hitting the reef. For advanced surfers, this could offer heavy, hollow waves, but the catch is the cross-onshore wind. The later afternoons are marked “clear” or “some clouds,” but the wind stays cross-on. It’s going to be lumpy and challenging. For beginners, this is far too big.

After the 20th, the swell eases from 7ft down to 5ft by the 23rd, but it remains S/SSW with periods dropping from 16 to 12 seconds. The wind is mostly onshore or cross-onshore, so the quality is always compromised.

So, is there any good surf? With all that west wind, this setup looks more interesting for kite surfing than a clean paddle session at Inside Reef. The wind and swell just aren’t coming together for us. The only reason to paddle out would be the 17th afternoon for the long-period lines, or the 18th-19th if you’re an experienced local who can handle a bumpy, powerful reef. But don’t expect perfection – just big, raw, windy surf. Crowds can show up here sometimes, but with conditions like this, it’ll be quiet.

Rusty.
