The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the Samoa Peninsula over the next couple of weeks.
Right off the bat, I gotta be straight with you: it’s a rough start. The first week and a bit is pretty much a write-off for decent waves. From Thursday the 13th of August right through until about Tuesday the 18th, it’s all messy, onshore slop. We’ve got northwest winds messing up lines that are coming from the WNW and NW, with swells sitting around 2 ft to 6 ft. The combined wave energy is moderate, reading between 299 and 549, but it don’t matter when the wind’s got it all chopped out. The water temp is about what you’d expect for this time of year, nothing wild there.
Things start to look a little less bleak on Wednesday the 19th, but it’s still only marginal. There’s a tiny window on the Wednesday morning with a light onshore wind and a 3 ft swell from the WNW, but it’s nothing to get excited about. We get a bit of a lift heading into the weekend of the 22nd and 23rd. The standout window in this whole forecast, and the only one I’d really point you to, is Sunday the 23rd of August. We’ve got a solid 7 ft swell from the NW with an 8-second period pushing through, and the wind is blowing lightly from the NW, which for this spot means a clean, offshore texture. The combined energy is strong, hitting 678 to 721. This is the best we’re going to see. For the intermediate surfer, that’s a solid, clean day. Keep in mind, it can get a bit of a crowd here sometimes, so get out early.
After that little burst, it fades back into mediocrity. The final days, from the 24th on, see the swell dropping back into the 5 ft to 7 ft range but with those cross-onshore northerly winds messing it up again. There’s a sniff of some long-period groundswell from the SW on the 26th, but at just 2 ft, it’s not offering anything rideable.
So, to wrap it up: the whole first week is a dud. The only real chance for a decent paddle is Sunday the 23rd, with clean, 7 ft NW swell and light offshore wind. Everything else is a mix of wind-affected conditions or just too small. It’s a long stretch of quiet, but that one Sunday could be a gem.
Rusty.
