The Lowdown
Alright, Rusty here, and I’m looking at a tough stretch for Hikkaduwa. There’s a big, empty gap in the forecast. No real surf on offer until the very first day of August, so that’s a long time to wait for a spot that usually delivers.
The culprit is the wind. Main Reef (Hikkaduwa) is wide open to the southwest, and we’ve got a constant flow of westerly cross-on and onshore breezes, with a lot of thunderstorm risk mixed in. The water is a touch warmer than normal at 83.3°, but that’s small comfort when the waves are all chopped up and messy.
The ocean has plenty of energy, just not the right wind. For most of the period, the combined energy is strong, hitting numbers like 1186 and 1502, and even peaking at 2064 on the 31st of July. But with the wind hitting it from the wrong angle, the quality is just poor. It’s one of those times where the ocean is angry, but not in a good way for us.
The one real highlight, and the only window that looks good, is the morning of the 1st of August. We’ve got a 5.6 ft swell from the SSW with a 16-second period – that’s proper groundswell energy. The wind eases off, coming from the WSW at 9 mph, and it’s blowing straight offshore. That’s our best bet. The combined energy is strong (1858), and with the offshore wind, Main Reef should look clean. It’s a long-range call, so keep your fingers crossed, but that morning is the one to circle on the calendar. The rest of that weekend is still a bit dubious, but that Monday morning has potential.
