The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu around Hikkaduwa.
Straight up, this is going to be a grim two weeks for anyone wanting a proper surf. For the entire 16-day window, there is not a single session that I’d be stoked on. The first good bit of news? There isn’t any. That’s how poor this run is.
We start off with a big blank gap right from today. The first recommendation would be the 20th of August, but it’s instantly a no-go. Through Thursday and Friday, we’ve got a solid 7 ft plus, long-period SSW groundswell hammering the coast, but the wind is howling onshore from the W and WSW at 15 mph. That’s creating poor, blown-out conditions with storm risks. Not even worth a paddle.
The whole pattern just doesn’t let up. From the 20th right through to the 4th of September, virtually every morning and afternoon is either cross-onshore or onshore wind from the west. Swell sizes flicker between 3 ft and 8 ft, and the periods are often long – up to 17 seconds – which at a reef like Inside Reef (Hikkaduwa) could line up nicely, but the wind absolutely murders any chance of a clean face. The combined energy is moderate to strong, with values like 2366 and up to 4108 on the 31st, but that’s just raw power wasted on chop.
There’s a tiny glimmer on the 23rd of August, Sunday afternoon, where the wind drops a notch and we get a “Gentle breeze” with an onshore direction, but the swell is only 5 ft, and the period drops to 13 seconds. The score is marginal at best. Still not good.
Even long-range, things don’t improve. The 30th and 31st of August see the biggest energy (2961 and 4108), but it’s all cross-onshore wind and messy. This setup, with consistent onshore breezes and a reef break, honestly looks more interesting for kite surfing right now than paddle surfing.
Truth is, this area often gets these blank runs when the trade winds lock in. Forecasts can change, but right now, for the next 16 days, there’s nothing I’d recommend. Leave the board in the bag.
Rusty.
