The Lowdown
Alright, this is Rusty, and I'm looking straight at the Samoa Peninsula forecast. It's a bit of a tough stretch for us over the next 16 days. The water temp is sitting at about 56°F which is pretty average for the time of year.
The first real swell we see is a long-period groundswell from the SW pushing through Sunday morning the 16th, around 2ft with a 16-second period. That's a classic groundswell pulse, but the winds are light and onshore, and the consensus is that it's marginal. Not the cleanest entry to the week.
Truth is, from that point, the outlook gets messy. We've got a bunch of days, from Sunday afternoon right through to the end of the first week, with poor conditions. The wind is cross-onshore or onshore, and the wave quality just isn't there. Swell mixes up from NW with short periods, often below 8 seconds, making for lumpy, weak surf. The combined energy during the middle of the week hits moderate levels (say, around 592 on Wednesday), but with those onshore winds, it's just not a good paddle.
There's a bit of a tease on Thursday the 20th, with a 3ft WNW groundswell (11-second period) and light onshore winds, but it's still tagged as marginal.
The real standout—and honestly, the only one that puts a grin on my face—is the window around Sunday the 23rd. We're looking at a 6ft NW swell rolling in on the morning. That's a solid push. The wind is coming from the west at just 3 mph, which is a slight, near-offshore breeze. That'll clean up the face nicely. For an intermediate-level spot like Samoa Peninsula, it’s a good size—not too big, not too small. The period sits at 8 seconds, so it's more of a windswell component, but the cleaner conditions will make it a fun, punchy session on the sets. Just keep in mind that the break can get crowded from time to time.
Towards the very end of the forecast, around the 30th and 31st, we get another SW groundswell with a 16-second period. The size is small, only 2ft, but with clear skies and light cross-offshore or onshore breezes, it’s at least clean. Probably worth a longboard if you're keen for a glassy paddle, but it's not the standout.
So to sum it up: the whole period is pretty marginal for paddle surfing, with the wind being the main villain. If you’re going to pick a time, make it the morning of Sunday the 23rd for that clean 6ft NW swell. Otherwise, this setup looks more interesting for kite surfing with the steady cross-onshore conditions we see most days.
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.
