The Lowdown
Alright folks, Rusty here. Let's take a look at what's on offer for the Hikkaduwa area over the next couple of weeks.
Straight up, I gotta be honest with you, it’s a rough stretch. This forecast is a tough read for a surfer. We’re looking at a solid 16-day window, but it’s going to be a long wait for anything even remotely decent. The swell is there at times, but the wind and conditions just won’t play ball.
For the first week, from the 12th right through to the 22nd of September, it’s pretty much a write-off. We’ve got constant risk of thunderstorms, and more importantly, the wind is almost always cross-onshore or straight onshore, often blowing at a solid 18 to 19 mph. That’s going to chop everything up something shocking. Even when we see some decent sized, long-period groundswell rolling in from the SSW, the wave energy is massive—reaching into the thousands (like 2718 on Saturday the 12th)—but with that wind, it’s just messy. The water is a balmy 84°, which is a touch warmer than normal for this time of year, but that’s small comfort when the surf is junk.
The only break we have to look at here is Inside Reef (Hikkaduwa). It’s an exposed reef setup, and it’s fairly consistent, which is the only upside. The optimum swell direction is from the SW, and we do get pulses from that direction, but the wind is all wrong. For the whole first week, the scores are flat zeros and ones, with notes saying "poor surf conditions" or "marginal." It’s just not worth paddling out.
Now, we do get a little spike in size around the 19th and 20th, with waves pushing up to 7 ft from the SSW. That’s proper groundswell with periods around 16 seconds. But again, it’s accompanied by strong onshore winds. For a reef break, that’s going to be a washing machine. Over 8 ft is expert-only territory, and while this is just under that, with the wind howling, it’ll still be a handful and not much fun.
We then roll into the second week, from the 22nd onwards, and the swell direction shifts to the WSW. The period drops right off to 7 or 8 seconds—that’s short-period windswell, not the good stuff. The energy levels drop too, with combined energy readings around 700-1000. It’s still blown out with onshore winds of 18-19 mph. There’s really nothing to get excited about.
Honestly, for the whole 16-day outlook, I can’t point to a single standout session. It’s a long stretch of poor conditions. If you’re desperate for a paddle, maybe check the odd early morning on the 12th or 13th when the wind is a bit lighter, but don’t expect any kind of quality. With the constant onshore flow and a beach-and-reef setup, this might look more interesting for the kite surfers than us paddle guys for a good chunk of it.
Keep your head up, though. Forecasts can change, and it can’t stay this ugly forever.
Rusty.
