The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Inside Reef (Hikkaduwa). To be straight with you, the next couple of weeks are looking pretty grim. The wind is mostly onshore from the west and southwest, and the whole forecast is littered with "poor surf conditions" – no getting around it. The water temperature is sitting at 84°, which is a touch warmer than normal for this time of year.

The first few days, from Friday the 4th through to the end of the first week, are a write-off. The swell is on the small side, but the bigger problem is the wind. It’s blowing straight onshore from the WSW at 9 to 12 mph, with a lot of risk of thunderstorms. The wave energy is moderate, with readings in the 300 to 700 range, but the quality is just not there. Even the longer period swells that do show up later in the week are getting hammered by that onshore wind.

We’ve got a bit of a gap before anything changes. The real energy starts to build from around Thursday the 10th, with the swell picking up to 4ft from the SSW, and the period climbing to 16-17 seconds. The combined energy jumps into the four-digit range, hitting 1311, but the wind is still raw onshore from the west. This swell is a proper groundswell, but it’s going to be messy.

Friday the 11th sees a 5ft SSW swell with a period of 21 seconds in the morning – that’s a very long period groundswell. The energy is strong at 2031. But again, the wind is onshore. For a reef break like Inside Reef, that long period can be a blessing, but not with the wind ruining the surface.

The best chance, and I’m using that term loosely, comes on Saturday the 12th. The swell is up to 6ft from the SSW, with an 18-second period. The combined energy is very strong at 2913. The wind is still onshore from the west at 16 mph, so it’s not going to be clean. For a break that’s rated for advanced surfers, this size is fine, but the onshore wind will make it lumpy and tough. This is the standout simply because it’s the biggest, most powerful swell of the window, but it’s a long way from perfect.

The second week doesn’t get any better. The swell stays solid, with 6ft to 7ft SSW swells, and the energy is consistently strong (well over 1000). But the wind never lets up, staying onshore from the west or WSW. Even on the 19th, the last day in the forecast, we get a 7ft SSW swell with a 16-second period and very strong energy (2070), but the wind is cross-onshore, making it only marginal.

Honestly, for the entire 16-day window, there’s no day where the conditions align for a good session. The wind is the killer. It’s a blank run, and for this part of Sri Lanka, that’s not unusual when the monsoon winds are in charge. Keep an eye on the forecasts, but this one’s a pass for paddle surfing.

Rusty.
