The Lowdown
Alright, Rusty here again, this time with the numbers in feet for you. Let’s talk about Samoa Peninsula.
Right from the start, it’s a bit of a tough run. The swell is coming out of the NW, around 5 to 6 feet early on, with moderate energy. Problem is, the wind is blowing onshore or cross-onshore for almost the whole first week, and the period is short, about 7 to 8 seconds. Not giving us any proper shape. Water temps are about normal for this time of year.
Tuesday the 4th and Wednesday the 5th are frustrating – you’ll see 5 to 6 foot NW swell with light breezes, but the wind is either straight on the nose or cross-shore. You’ll get some bumpy little waves, but nothing you’d write home about.
Then we hit a real dry spell. From Thursday the 6th through to Monday the 11th, it’s mostly poor surf. Swell drops to 3 feet on Thursday and Friday, and even when it pushes back to 7 feet on Sunday the 9th, the wind is cross-onshore and ruining it.
There is one moment on Monday, August 10th that stands out. The afternoon shows 8 feet of NW swell with moderate-to-strong energy and a light cross-onshore breeze. That size is getting solid – too much for beginners, but for experienced surfers it’s the standout of the week. The wind is only light, so it should be cleaner than the rest of this period.
After that, Tuesday the 11th to Friday the 14th, the wind picks up. N and NNW winds at 10-15 mph make it choppy. Swell sticks around 5 to 10 feet, but with the cross-onshore chop, it’s going to be messy. That 10-foot swell on the afternoon of Wednesday the 12th is very strong but only for experts in those conditions.
Now look ahead to Sunday, August 16th. This is a whole different story. Swell direction shifts to WNW and the period jumps to 17 seconds – that’s proper long-period groundswell. Swell height is only 2 feet, but the energy is still moderate. The wind is light and onshore in the morning, keeping it glassy. This is the kind of swell that works best at reefs or point breaks. For a beach break, it might break too straight, but at Samoa Peninsula, the quality will be there, even if it’s small. Into Monday the 17th, we get 3 feet at 16 seconds with light onshore winds. Tuesday the 18th still has 4 feet at 12 seconds from the WNW. Small but beautiful.
The best call for the whole 16 days? Monday afternoon, August 10th, for the biggest, cleanest look at a proper NW swell under light wind. And for the second week – Sunday, August 16th – that long-period WNW groundswell is the real gem, even though it’s small. A long-range call, but if it comes through, that’s the one to wait for.
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.
Samoa Peninsula is 5 km (3 miles) from Eureka. If you plan a vacation in Humboldt County, look for hotels and other accommodation in Eureka. Eureka has rooms for a wide range of budgets as well as car hire and transport links.
