The Lowdown

G’day, Rusty here. Look, I’m not gonna sugarcoat it – this 16-day stretch for the Hikkaduwa region is a tough one. We’ve got a solid run of waves coming through, but the wind is going to be our biggest enemy. The water’s sitting at a warm 84°, which is a touch warmer than normal for this time of year, so at least you won’t need a wetsuit.

The big picture is this: consistent swell energy, but it’s almost always accompanied by a fresh cross-onshore breeze. That means lumpy, choppy, and generally poor surf conditions for the first 12 days straight. The combined swell energy is strong to very strong – often sitting between 1000 and 2389 (units) – so there’s plenty of power in the water, but it’s just not tidy.

Let’s start from Sunday, August 2nd. We’ve got a 8 ft swell from the west, but that 30 km/h cross-on wind from the west makes it a write-off. This pattern keeps up through Monday the 3rd, with 7 ft from the west and 35 km/h winds, and Tuesday the 4th drops to 4 ft from the SSW with a long 16-second period, but still those cross-on winds ruin it.

Wednesday the 5th sees a bit of a spike – 8 ft from the WNW, but with a short 8-second period and 30 km/h winds, it’s messy. For advanced surfers, that size is manageable, but the quality is poor. The rest of that first week and into the second week (August 6th to 11th) is more of the same: swells ranging from 3 ft to 6 ft, mostly from the south to SSW, with long periods (14-19 seconds) that would be great at a point or reef, but the wind is just relentless. The combined energy stays strong, often above 2000, which is a lot of moving water, but it’s all blown out.

Now, there’s a glimmer of hope around late in the second week. The first real standout is on Friday, August 14th. The afternoon sees a 2 ft swell from the SSW with a whopping 21-second period – that’s a very long-period groundswell – and the wind swings to a 20 km/h *on* direction from the WSW. This is marginal, but it’s the first time the wind is blowing straight onshore rather than cross-on, which could make it a little more rideable. The combined energy is still substantial at 1108.

Then Saturday, August 15th, could be our best bet. The morning and afternoon both have 3 ft to 4 ft swells from the SSW with an 18-second period, and again, 20 km/h onshore winds from the WSW. The scores are still a 1 out of 10, but these are the cleanest windows in the whole forecast. The combined energy jumps to 1544-1547, so there’s plenty of poke. For a reef break like Inside Reef, which is fairly consistent and exposed to the SW, this long-period SSW swell could actually wrap in nicely. The onshore wind won’t give you perfection, but compared to the rest of the fortnight, it’s the best on offer.

The crowd profile at Inside Reef says it can be “sometimes” busy, so you might not have it all to yourself, but with the poor conditions leading up to it, I’d expect a quieter lineup.

The final days, August 16th and 17th, drop back to the same old cross-on wind and poor to marginal surf. The forecast confidence for the second week is lower, so keep an eye on it, but right now, the 15th of August is the day to pencil in. It’s not a classic, but it’s got the best chance of a few clean ones.

Rusty.
