The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks. We’re gonna talk about Samoa Peninsula – that’s our spot for this whole run.
The long story short? We’ve got a rough start ahead. The first swell pulse that shows up hits on Tuesday the 15th with 6ft of NW windswell at a short 8 seconds, but it’s blown out by a cross-onshore wind, so that’s a solid scratch. That sets the tone for the next several days – we’re looking at a dry spell from the 15th through to the 20th of September, where the conditions just aren't clicking. The swell sticks around in the 5ft to 6ft range from the NW, but the winds stay messy, and the scores are in the gutter. It’s frustrating because the water temp’s sitting at 57°, which is right about average for this time of year, so it’s not a matter of the water being weird – it’s just the atmosphere being uncooperative.
We finally get a glimmer of hope on Sunday the 20th with a bit more size (5ft) and a shift in direction, but that afternoon gets chunky again. Monday the 21st sees the swell up to 7ft, but it’s still cross-onshore and the wind state is messy. By Tuesday the 22nd, the swell leaps up to 8ft in the morning and 10ft in the afternoon from the NW, with moderate wave energy (1194), but the cross-onshore winds mean it's a messy, choppy mess. That’s really only for the experienced crew, if at all.
The standout moment, the one you want to mark on your calendar, is Wednesday the 23rd. The swell drops to a solid 7ft from the NW, but the wind goes glassy – dead calm, smooth as a lake. That’s the day it all comes together. With a period of 9 seconds, it’s not super long, but it’s workable, and the combined energy (833) is solid. That is your best bet. After that, the swell fades out through the following week, and we’re back to light, choppy conditions and smaller surf, with a few pulses of long-period (13-17 second) SW swell on the 26th and 29th, but those come with bad wind, so they’re just eyed from the beach.
So, if you’ve got one day to paddle out this fortnight, make it the 23rd. It’s the only time everything feels right.

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.
