The Lowdown
G’day. Rusty here. Let’s be straight with you. The next couple of weeks around Hikkaduwa are looking pretty grim for a proper paddle session. We’ve got a solid South-Southwest groundswell wanting to push through, but the wind is just going to have its way with it, and it’s going to be messy more often than not.
The first few days, starting Wednesday the 9th and into Thursday the 10th, the ocean’s building from that SSW direction. We’re looking at chest to head high surf, with the swell energy climbing from a moderate 640 to a strong 1436 by Thursday morning. The water’s sitting at 84.2° and it’s a touch warmer than normal for this time of year, which is nice, but the onshore W wind at 12 mph is just going to make it lumpy and uninviting. Forget it for a proper surf, the conditions are just poor.
The swell really peaks on Saturday the 12th, with the energy at 2694 in the morning. That’s a strong pulse of SSW groundswell, pushing well overhead at 6.9ft. But, and it’s a big but, it’s all wind-blown and the forecast calls for poor surf conditions. This one’s not worth the paddle out. It settles down on Sunday to a still-strong 5.6ft, but again, it’s just onshore and choppy.
The middle of next week sees a weird drop in period on Tuesday the 15th, down to 8-9 seconds with a cross-onshore breeze. That’s a sign of a weaker, shorter-period swell mixing in and it’s going to be a washing machine out there. It’s still big at 8.2ft, but the quality just isn't there. This one’s not for the faint of heart, and honestly, looks more interesting for the kite surfers than us.
The story doesn't really change much through to the 24th. We get pulses of SSW groundswell, but it’s always onshore. The Ides of September, the 23rd, a Westerly swell with a super short 7-second period rolls through at 6.2ft, but it's junky. The best you can hope for are a few of the more protected corners, but for Inside Reef specifically, it’s going to be tough to find a clean one.
Honestly, the whole 16-day window is a write-off for any decent surf. There are no standouts. The wind just doesn’t give us a break. It’s one of those stretches where you’re better off leaving the board in the shed.
