The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's cookin' at No Pass. Right off the bat, I gotta tell ya, it's a lean start. We've got a reef setup here that's exposed to the WNW, and for the first several days, it's pretty average.
Water temp's sittin' around 57°F, which is about normal for mid-August, so nothin' wild there.
The outlook kicks off on Monday the 17th, but honestly, it's more of a tease. We're looking at a small 3ft SSW swell with a solid 15-second period, but the wind is a light cross-onshore from the WNW. The combined energy is moderate (457), but it’s just that "marginal" kind of feeling. You'll be fighting a bit of wind chop for a wave that's not really gonna give you much.
This slump continues right through the 21st. A mix of small swells, mostly from the SSW, in the 1ft to 3ft range, but the wind never really plays ball. It's all cross-onshore. The energy levels are weak to moderate, with readings like 393 and 313, which just confirms the lack of punch. It's pretty flat and poor for a solid week.
Now, there’s a little flicker on the radar for Saturday the 22nd. The afternoon sees a sudden switch. The swell jumps up to 5ft, but it's a short-period 6-second churn from the NW (energy 380). The wind, however, goes glassy. That's the one real positive. For a few hours, it might look clean and smooth, but that period is so short it's going to be a bit fat and gutless.
Sunday the 23rd holds some hope too. Afternoon brings another glassy session, with a 4ft NW swell (8-second period, energy 475). It's still not big, but clean surf is clean surf. It's a decent entry point for the week if you're not fussy.
The pattern stays inconsistent. We see a few more glassy windows on the 24th and 25th, but the swell drops right back to 2ft - 3ft. The period is long again (16-18 seconds), which is nice for shape but those long gaps between sets will be noticeable.
We hit another dry patch from the 27th. The wind picks up from the NW and NNW, getting up to 19 mph. It's choppy and lumpy under clear skies. Swell heights are mixed but the conditions are just nasty. One afternoon on the 29th (Saturday) sees energy jump up to a very strong 1053, with a 4ft SSW swell at 18 seconds, but the cross-onshore wind ruins the party.
The Standout – Finally.
After all that mediocrity, things actually come together on the last day of August, Monday the 31st. The entire morning and afternoon is glassy. The swell is a clean 3ft to 4ft from the SSW, with a nice 15-second period (energy around 673). That's groundswell. That's proper lines. The wind is dead still, and the forecast calls for "very good surf conditions." This is the pick of the outlook – a proper reward for waiting it out. The waves will have shape, the face will be clean, and it won't be huge but it'll be excellent.
Following that, Tuesday the 1st of September afternoon gets a mention too. We get a glassy window again, with a bump up to 5ft from the NW. But the period is short, just 7 seconds. The energy is moderate (709). So while it's clean, that short period means it'll be a bit of a flurry. The 31st is your real target.
Signing off, 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.
