The Lowdown
G’day, Rusty here, checking in from the Hikkaduwa side. Look, I’ll be straight with you—this stretch of 16 days is a tough one. The ocean’s churning up some solid energy, but the wind’s just not playing ball, and the wave quality is suffering for it. We’ve got a long run of days where the conditions are poor, so don’t plan any epic sessions just yet.
We kick things off on Thursday afternoon, the 3rd of September, at Inside Reef (Hikkaduwa). The swell’s coming in at 5 ft, from the SSW, with a period of 13 seconds. That’s a decent groundswell with some punch—the combined energy is sitting at 1040, which is moderate. But here’s the rub: the wind is howling from the WSW at 12 mph, straight onshore. It’s going to be choppy and messy, and with a risk of thunderstorms, it’s not a pretty picture. The water’s a warm 84°, which is a touch warmer than normal for this time of year, so at least you won’t need a wetsuit. But honestly, this is one for the hardcore only, and even then, it’s marginal.
From there, it’s a real slog. Friday the 4th through to Monday the 7th, the swell drops a bit—5 ft down to 2 ft—but the wind stays onshore from the WSW or W, 9 to 12 mph, with those same storm risks. The combined energy drops from 805 down to 356, so it’s getting weaker and weaker. The period hangs around 10 to 13 seconds, but the onshore breeze just kills it. Poor conditions across the board.
Then we hit a bit of a lull. Tuesday the 8th and Wednesday the 9th see the swell drop even more, 3 ft to 3 ft, with periods stretching out to 15 or 16 seconds—longer period groundswell, which would normally be a good sign, but the wind is still onshore at 12 to 16 mph. The energy picks up a bit, 567 to 774, but it’s all for nothing with that wind. The waves are likely to be too straight and weak for the reef.
Now, things get interesting, but not in a good way. On Thursday the 10th of September, the swell jumps back up to 5 ft from the SSW, period 17 seconds, and the combined energy rockets to 1528—strong wave energy. That’s a proper groundswell. But the wind is cross-onshore from the W at 16 mph, and the forecast says “moderate cross-onshore and choppy.” This is a setup that looks more interesting for kite surfing than paddle surfing, especially for a reef break like Inside Reef. It’s going to be a bumpy, lumpy mess.
The following days, from Friday the 11th to Tuesday the 15th, the swell holds steady between 4 ft and 5 ft, with periods of 14 to 18 seconds, and the combined energy stays high—often over 1000, peaking at 1943 on the morning of the 15th. That is a lot of energy in the water. But the wind is relentless: onshore from the W or WSW at 16 to 19 mph. It’s a fresh breeze, and it’s just going to trash the waves. The break is exposed, and with that wind direction, it’s not going to clean up. The water temperature anomaly isn’t provided for these days, but given the consistency of the wind, it’s a no-go.
As we move into the second week, the swell starts to fade. Wednesday the 16th drops to 4 ft, then 4 ft, with periods around 13 seconds, and the energy drops to 868. Still onshore wind. By Thursday the 17th and Friday the 18th, we’re down to 2 ft to 3 ft, with periods of 15 to 18 seconds, and the energy is moderate—617 to 974. But the wind is cross-onshore again, making it choppy. The last day, Friday the 18th, shows some clouds, but that’s about the only positive.
So, overall, there’s no standout session here. The best on offer, if you’re desperate, might be the morning of the 10th of September, with that 5 ft, 17-second groundswell, but the cross-onshore wind and chop make it a real gamble. It’s a reef break, so the long period could give some nice lines, but the wind will likely ruin it. For the rest, it’s a long stretch of poor conditions. Hang in there, though—it won’t stay this way forever.
Rusty.
