The Lowdown
Alright, this is Rusty. Let's have a look at the local picture.
Honestly, the first week and a half are a write-off. The swell is tiny and messy, and the wind is mostly cross-onshore. From Monday the 17th of August right through to about Saturday the 22nd, it’s pretty lifeless. We’re looking at knee-high slop with a combined swell energy that barely gets going – the biggest number in that stretch is just 563 (moderate). Not worth the paddle.
There’s a real shift on Sunday the 23rd of August, though. The morning has a small window with an onshore wind, but it’s the Sunday afternoon that finally gives us something. No Pass will see a 4ft swell from the NW with a 9-second period. The wind drops to glassy. That's clean. It’s a reef break that can handle that direction, and with the glass, you’ll get a proper wave. The combined energy is up to 529 (moderate). This is the first standout. It’s still small enough for intermediates, and with a score that good, it’s your best bet this side of the month.
After that, Monday the 24th of August through the middle of the week is more knee-high dribble from the SW, with some glassy windows but no real power.
Now, look ahead to Thursday the 27th of August. The morning bumps up to a 6ft NW swell with a short 8-second period and a combined energy of 719 (moderate). It’s a little chunky and short-period, which can be a bit sectiony at a reef. The real highlight comes later. On Friday the 28th of August, we get a 5ft NW swell, 8-second period, and the wind goes glassy in the afternoon. That is going to be super clean, with a combined energy of 570 (moderate). That Friday afternoon is the second real standout. It’s got that long-period groundswell feel from the SW late in the month, but for the NW pulse, the wind is the winner.
The very tail end, Monday the 31st of August, throws up a serious contender. A 4ft SSW swell with a 16-second period – that’s proper groundswell. With glassy conditions, the combined swell energy hits 1060 (strong). That's a big number. The period is long, so it will be bowly and powerful on the reef, but might close out a beach break. For No Pass, this could be excellent, but it's for experienced surfers only at that size and period. It’s the best-looking energy of the whole forecast, but it’s far out, so keep an eye on it.
Bottom line: Sunday the 23rd afternoon and Friday the 28th afternoon are your clean, fun windows. The 31st has the most power, but that’s for the crew who know what they’re doing.
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.
