The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for Inside Reef (Hikkaduwa).
Right off the bat, I gotta be straight with you – this stretch ain’t looking like it’s gonna dish out many smiles. The water temp’s sittin’ about average for this time of year, so no surprises there. But the vibe? It’s pretty grim for the next week. We’ve got onshore westerlies blowin’ 12 to 16 mph most days, and the swell energy is all over the place – moderate to strong (values like 2297, 2206, 1321) – but it’s wrapped in poor surf conditions. The swell direction is mostly SSW, which is off the optimum SW for this spot, and the period is long, around 14 to 16 seconds, which would normally mean some grunt, but the wind’s just ruining it. Thursday 20th August through Monday 24th August is a total write-off – scores are zeroes and the waves are messy.
There’s a glimmer on Saturday 22nd August afternoon, where the wind goes cross-onshore and the score crawls to a 1 out of 10, with 6 ft of S swell at 15 seconds. That’s marginal at best – think lumpy, questionable tide. Sunday 23rd August is similar, with 5 ft S swell and onshore wind, still a 1. Then we hit a real dry patch: from Monday 24th August afternoon through to early September, it’s all poor conditions, zero scores, and onshore or cross-onshore wind. The only slight uptick is on Wednesday 2nd September afternoon, when we get a 1 again – 6 ft SSW swell, 14 seconds, but still onshore.
The best of a bad bunch? Honestly, there’s no standout. The only day that even sniffs a recommendation is Saturday 22nd August afternoon, but it’s a long shot – just a 1 out of 10. If you’re desperate, you could paddle out for a sketchy session, but don’t expect much. The rest of the 16-day window is a ghost town for surf.
Rusty, signing off.
