The Lowdown
Alright, let’s talk about it. The surf over at Inside Reef (Hikkaduwa) is a bit of a mixed bag for the next couple of weeks. We got a lot of westerly wind and it’s going to mess with the surface for a few days. Water temps are reading about 83°F, which is pretty normal for this time of year.
The first real window of interest is on Sunday, the 9th. We’ve got a 6ft south swell with a 17-second period and moderate energy at 2358. But the wind is still cross-onshore, so it’s not going to be clean. It’s a marginal call at best.
Through the middle of next week, the quality drops off. The swell shrinks, the period shortens, and the wind stays on it. It’s not great.
The real standout, and the one I’m hyped about, is the window from the 18th into the 19th. It’s a bit further out, so take it with a grain of salt, but the models are showing some serious power. The 18th has the swell at 7ft to 7ft from the SSW, with an 18-second period. The energy is kicking up – 2961 and 3029. That’s a strong pulse. The direction is perfect for this reef.
Then on Wednesday the 19th, it looks like the biggest day. The afternoon shows an 8ft SSW swell with a 19-second period and the energy jumps to 4917. That’s a big, powerful groundswell. At this size, on a reef, it’s strictly for the experts. The wind is onshore, but with that much juice, it’s going to be a heavy session for those who are keen.
There’s also a late shout for the 21st with 7ft and 7ft SSW swells, but the period drops and the energy is a bit less. It’s still good, but the best of the best is the 19th.
So, the short term is average at best. But that window from the 18th to the 19th has the potential to be a proper, powerful swell. It’s a long way out, so don’t get too locked in, but the ingredients are there for something special. For now, keep your gear ready and watch the sky.
