The Lowdown

Alright, Rusty here. Let's get into it.

Look, I'm not gonna lie to you, the next couple of weeks are a bit of a mixed bag for the Hikkaduwa area. We've got some serious swell energy coming through, but the wind is going to be a real pain in the neck for most of it. The real standout is going to be a short window of big, powerful groundswell, but you'll have to work for it and it's definitely not for the faint of heart.

The main break on offer is Inside Reef (Hikkaduwa). It's a reef setup, so it's for advanced surfers only, and it's fairly consistent. The water temp is sitting at 82°, which is bang on average for this time of year, so no surprises there.

We kick off with a pretty grim stretch. From Wednesday the 12th through to Sunday the 16th, it's a write-off. We're looking at onshore and cross-onshore winds around 12 mph to 16 mph, with a lot of "risk tstorm" in the forecast. Swell heights are tiny, between 3 ft and 5 ft, and the combined wave energy is weak to moderate (between 591 and 948). The surf is just poor, so don't bother.

We get a small glimmer on Monday the 17th afternoon. The wind is still a moderate cross-onshore breeze, but the swell starts to build. We see a 4 ft swell from the SSW with a very long period of 21 seconds. The combined energy jumps to 1691, which is moderate. The conditions are still only marginal, but it's a hint of what's coming.

Then, here's the highlight. Tuesday the 18th is the day to watch. The swell pumps up to 8 ft from the SSW with a 19-second period. The combined energy is massive, hitting 4343 for the morning and 4129 for the afternoon – that's strong wave energy. But, and it's a big but, the wind is still a moderate cross-onshore. The surf quality is poor, but the wave state is "moderate cross-onshore and choppy". This is a big, powerful groundswell, and with that long period, it's going to be powerful and walled up. For experts only, it's worth a look if you can handle the chop. The wind is a bit better on Thursday the 20th afternoon, turning to a gentle cross-onshore, but the swell is still 7 ft to 7 ft, so it's still a heavy, advanced-only wave.

After that, from Thursday the 20th through to Monday the 24th, the size drops back to a more manageable 5 ft to 6 ft, but the wind remains a constant cross-onshore or onshore breeze. The energy is moderate (between 1040 and 2252), but the conditions are consistently marginal. It's not great, but it's better than the flat spell at the start. The best of this run is probably Saturday the 22nd afternoon with a gentle breeze and 6 ft of S swell, or that Monday the 24th morning with a 6 ft S swell and a 16-second period, but the cross-onshore wind will mess it up.

The last few days from the 25th to the 27th look like a return to poor conditions with onshore winds and smaller swell. Honestly, for the whole 16 days, the only real standout is that massive pulse on Tuesday the 18th, but it's a choppy, expert-only mission. For the rest of us, it's a lot of waiting for a clean window that never really opens up.

Stay safe out there.
