The Lowdown
Alright, Rusty here again, giving you the same rundown in feet and miles per hour. The water's a chilly 55°F, over a degree and a half colder than normal for this time of year—time to break out the booties.
Staring down this 16-day window, it's a pretty grim outlook. We're looking at a whole lot of days with poor conditions. The first time we see anything even close to rideable is the morning of Sunday, August 23rd, and that's only called marginal—nothing to write home about.
The main issue is a stubborn north-northwest to north wind that stays cross-onshore or onshore most of the time. The swell direction swings from a short-period northwest to a weak long-period southwest, but that wind just ruins every chance we get.
That first marginal window on the 23rd has the swell bumping to 5ft out of the northwest with a short 7-second period. The wind is a light westerly, still cross-onshore, so you'll be dodging some bumps, but there might be something to ride.
Then things get more powerful. From the 25th to the 27th of August, the wave energy jumps into strong territory (486 to 1325 combined energy). We're looking at a solid northwest groundswell hitting 8ft to 10ft by Wednesday the 26th, with a 9-second period. That's big, expert-only territory. But the wind is screaming out of the north at 12 to 16 mph, cross-onshore, turning it into a washing machine. For a beach like Samoa Peninsula, that's more of a kiteboarding setup than a wave for your shortboard.
Honestly, the pick of a terrible lot is the morning of Thursday, August 28th. The swell drops back to a still-chunky 5ft from the northwest, and the wind is a lighter cross-onshore breeze. It won't be clean, but it'll be the least messed up we've seen in a while. And with crowds sometimes an issue here, you might have some company.
So, plain speaking: this is a rough stretch of forecasts. If you absolutely have to get wet, aim for the 28th morning. Otherwise, it's time to find a new hobby for a couple weeks.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Samoa Peninsula may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
