The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer around Hikkaduwa.
Honestly, it’s a grim stretch ahead. For the next two weeks, we’re looking at a near-continuous run of poor surf conditions. The main issue is that persistent cross-onshore wind from the west, blowing at 15 to 19 mph, which just kills any chance of clean waves. The swell is hanging around, but it’s messy.
The first real glimmer of anything decent doesn’t show up until Monday, the 17th of August. Even then, it’s only a marginal call. The afternoon might see a slight improvement with a gentler breeze, but the swell is small at 4ft from the SSW, and the wave energy is moderate (1310). It’s still a bit choppy and borderline. Not something to get excited about.
The biggest pulse of the run hits on Tuesday, the 18th of August. The swell bumps up to 7ft to 7ft from the SSW, with a very long period of 18 to 19 seconds. That’s a serious groundswell with strong wave energy (3164 to 3652). But the wind is still cross-onshore or onshore, and with that size and period, Main Reef (Hikkaduwa) is going to be a washing machine. That’s strictly for the experts, and even then, conditions will be rough. For a regular surfer, it’s a no-go.
The water temperature is sitting at 84°F with a positive anomaly of 3°F, so it’s a touch warmer than normal for this time of year.
The real standout is that there just isn’t a good window in this 16-day outlook. The wind refuses to cooperate, and the swell that does show up is paired with terrible conditions. If you’re a kitesurfer, that 6ft+ swell with strong onshore wind might look interesting, but for paddle surfing, it’s a write-off. The sea is staying angry, and the forecasts can change, but right now, it’s a waiting game.
Rusty.
