The Lowdown
Righto, let’s dive into what’s happening at one of my local haunts.
Alright, so the outlook for the next 16 days is frustrating, to be honest. The first solid recommendation doesn’t appear for a while, so there’s a big gap of nothing good leading into some promising—but uncertain—swell.
The first bit of hope comes much later, so we gotta be patient.
Starting way down the line, around Thursday, August 28th, things start to get interesting. For a few days around there, we’ve got a very long-period swell rolling in from the SSW. The swell height will be building, getting into the 8 ft range by Monday, September 1st and into September. The energy behind this is massive, with the combined swell energy reading at 3350 to 3951 — that’s strong to very strong wave energy. The period is hitting 18 to 19 seconds, which is very long-period groundswell, meaning longer sets and more power, but it can be a bit straight at a beach break.
The problem is the wind. It’s a moderate breeze (12 to 19 mph) from the west, which for Inside Reef (Hikkaduwa) is onshore. That’s going to make things messy and choppy. The forecast is all “poor surf conditions,” “marginal,” or “risk tstorm.” Even with that big swell, the quality isn’t there. It’s looking more like a kite-surfing setup than a clean paddle-surf day. That’s a real shame because the size is there for the advanced crew.
The optimum swell direction is SW, and this swell is coming from the SSW, so it’s close but not perfect. The water temp is 83°F and the anomaly is only 1°F, so it’s about average for this time of year, no real shock there.
The only standout worth mentioning here is Inside Reef (Hikkaduwa) from August 31st into September 1st. The swell will be big (8 ft) and very long-period (17-19 seconds), with strong energy (over 3000). But it’s an advanced-only zone, and with onshore wind, it’s going to be a battle. Crowds are *sometimes* an issue there, but with the low-quality forecast, it might be less busy. This is a long-range call so treat it as promising but less certain. For the rest of the first week, it’s just no-go.
So, bottom line: a lot of waiting for a swell that looks powerful but likely blown out. Not the best week.
