The Lowdown
Alright folks, Rusty here. Let's get into it. We’re looking at a stretch where the surf just isn't playing ball. I’ve got to be straight with you: for this entire 16-day window, there’s nothing I’d call a good session. It’s a rare blank run for this area, so if you’ve got the itch, maybe keep an eye on the forecasts because these things can turn around.
The main spot on the radar is Inside Reef (Hikkaduwa). It’s an exposed reef setup that wants a swell from the SW to be at its best. The water's sitting at 84°F, which is a touch warmer than normal for this time of year, so you won’t be needing a wetsuit.
Now, looking at the dates, from Tuesday the 4th of August all the way through to Monday the 17th of August, it’s just poor surf conditions day after day. We’ve got solid swell energy coming in – often strong to very strong (figures like 1672, 2144, 2532) – with waves ranging from 3 ft up to 6 ft. The problem is the wind. It’s blowing from the W and WSW at 12 to 19 mph, putting it right onshore or cross-onshore, which is just chopping everything up. A lot of these swells are long-period groundswell (16 to 20 seconds), which would usually be a treat, but with this wind, it’s a messy, blown-out affair. Thursday the 6th and Saturday the 8th morning see some waves pushing 5 ft to 6 ft, but again, the onshore wind ruins it.
There’s a tiny glimmer on Tuesday the 18th of August. The afternoon shows a "marginal" call with a score of 1 out of 10 – the best we get. Swell is 5 ft from the S at 17 seconds, and combined energy is very strong (2316). But the wind is still cross-onshore from the W at 12 mph. You’d be battling moderate cross-onshore chop and the risk of thunderstorms. It’s not worth the paddle.
The last few days, from the 15th of August onward, the swell drops off a bit (3 ft to 5 ft) and the period shortens, but the onshore wind pattern sticks around. No standout sessions here, folks.
Honestly, with the wind and the conditions, this setup looks more interesting for kite surfing than paddle surfing.
Stay tuned, things can change.
Rusty.
