The Lowdown
Alright folks, Rusty here. Let's break down what the next couple of weeks looks like for us.
Honestly, the outlook for Samoa Peninsula is a bit of a mixed bag. We've got some swell running through the period, but the wind and conditions are going to be the main thing to manage. It's not a total write-off, but you'll need to be picky.
Water temp is around 56°, pretty standard for the season.
The first week or so is a bit of a grind. Starting Sunday the 16th, we've got a super long-period (16 seconds) groundswell rolling in from the SW at 2ft. The energy is weak and it's coming with a light onshore breeze. It's marginal at best. That pattern of small, weak surf and onshore winds is the story through Monday and Tuesday. The swell tries to build a little mid-week, but the winds and short periods just mess it up.
The first real standout pops up a week from now, on Wednesday the 26th. We get a solid increase to 5ft of NW swell, still a short period, but the wind turns glassy in the afternoon. That's the moment. The combined energy is moderate, and with that glassy surface, it's going to be the cleanest and most user-friendly conditions on offer. It’s not a huge swell, so it's good for intermediates and the crowds might be around, but that clean face will be worth it.
The next day, Thursday the 27th, drops a little in size but still holds 5ft to 5ft from the NW. The wind goes cross-shore, so it'll be a bit chopped up, but still surfable.
Looking deeper into the second week, there's another pulse of NW swell hitting around Sunday the 30th and Monday the 31st, but it’s mostly meeting onshore winds and the energy is short-period, so it’s hard to get excited about it. You'll get a few 2ft to 3ft waves from the SW and W with a longer period, but the onshore wind will ruin the shape.
For the best surf on the cards, aim for Wednesday the 26th at Samoa Peninsula. That glassy afternoon window with a bit of swell is our only real highlight.
Rusty.

Information about the Samoa Peninsula Surf forecast
The above surf forecast table for Samoa Peninsula provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Samoa Peninsula can be found by selecting the local surf guide option on the grey menu. Our Samoa Peninsula surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Samoa Peninsula) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
