The Lowdown
Alright, Rusty here again, breaking down the same outlook but in feet and miles.
It’s a lean run for No Pass (O‘ahu) in the 16-day window. Most of it is just waiting through messy, onshore slop until one afternoon finally delivers.
Water temp is around 59°F, pretty average for the season.
From August 22nd through the end of the month, it’s almost all poor. Swells run from about 1ft up to 4ft, but the wind is consistently out of the NW, cross-onshore, and the wave shape is junk. There’s one afternoon on the 23rd with 5ft from the NW, but it’s a short-period 7-second windswell and cross-on, so it’s not surfable. The combined energy numbers are mostly in the hundreds, up to 991, which is moderate to strong, but the quality is missing. Nothing scores higher than a 1.
Come September, you’ve got a bigger pulse on the 2nd—7ft from the NW with a short 8-second period. That’s strong energy (1199), but it’s windy and bumpy. Only for experts, and even then, it’s a chore.
The standout is the 5th of September, Saturday afternoon. Swell is 4ft from the SSW, with a long 16-second period. The wind goes glassy. That’s the cleanest we’ll see all forecast. The morning is still a little cross-on, but by afternoon, it’s smooth. The guidance says “very good surf conditions.” That’s the one to aim for. Crowds are possible, but the quality makes it worth it.
Everything after that fades back into so-so conditions with onshore wind.
So, your best bet: wait it out, then hit that Saturday afternoon on the 5th of September. The rest is mostly choppy and cross-on.
Stay salty,
Rusty

Information about the No Pass Surf forecast
The above surf forecast table for No Pass provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at No Pass can be found by selecting the local surf guide option on the grey menu. Our No Pass 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 (No Pass) 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 No Pass 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.
No Pass is 86 km (53 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.
