The Lowdown

Alright, Rusty here, and I’m giving it to you straight for the Hikkaduwa zone. It ain’t pretty. The swell is trying to show up from the south and south-southwest, with some long-period groundswell in the 13 to 19-second range, which could be nice on the reef, but the wind is the enemy. We’re stuck with a steady diet of moderate westerly and west-southwesterly winds, blowing right onshore or cross-onshore almost every single session. That’s gonna make it choppy and poor.

The water temp at the first spot is 83°F, with a 1°F anomaly, so pretty much what you’d expect for this time of year.

Let’s get into it. Starting Sunday afternoon, August 23rd, Inside Reef (Hikkaduwa) is showing 4ft of swell from the south, period 13 seconds, but that 20 km/h wind from the WSW is right on it. The combined energy is moderate (1089), but the call is poor surf conditions, and that’s the story right through.

Monday the 24th through the end of the month, we see swell sizes from 3ft up to 6ft, with periods between 13 and 19 seconds, giving us some nice groundswell potential, but every time that wind cranks up from the west at 20-25 km/h, it’s on or cross-onshore. You’ll see energy numbers in the thousands, like Thursday morning the 27th with a 6ft SSW swell, 19-second period, and strong energy (2816), but it’s all blown out.

Into the first week of September, it gets bigger but not better. On Monday August 31st morning, we’ve got 7ft from the SSW, 18-second period, very strong energy (2998), and the wind is 25 km/h onshore. By Tuesday September 1st, the wind picks up to 30 km/h, swell is still 7ft. That’s expert-size surf, but with that wind, it’s a mess. Not for beginners.

The only small ray of light is Friday September 4th afternoon. The sky clears, wind eases a bit to 20 km/h from the WSW (still onshore), and you’ve got 5ft from the south, period 11 seconds. The energy is moderate (824). It’s not clean, just the least poor of the lot.

After that, it fades fast. By Monday September 7th, we’re down to 2ft and 2ft, from the south-southwest and southeast, with cross-onshore wind and weak energy (435 and 195). Flat and choppy.

The Best of a Bad Bunch: There is no true standout. Inside Reef is the only break in the game, and it’s a constant fight with the wind. If you absolutely had to pick a session, Friday afternoon September 4th is your best bet, with lighter onshore wind and clearer skies. The biggest energy days, like August 27th and 31st, have size and long-period groundswell from the SSW, but they’re also blown out. The swell direction isn’t a perfect match for the optimum SW either. Honestly, with this wind pattern, it looks more promising for kite surfing than regular surfing. It’s a long, dry spell, and while forecasts can always change, this stretch looks like a write-off.

Rusty.
