The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way for No Pass.
The next couple of weeks are a bit of a mixed bag. We’ve got some moderate energy coming in early, but the winds are going to be a problem for a lot of it, turning things messy. The water temp is sitting at 56°, which is about a degree cooler than usual for this time of year, so nothing too wild, just a touch of that autumn chill starting to sneak in.
The first proper chance to get wet kicks off on Saturday afternoon, the 15th. Swell is a clean 3ft from the SSW with a very long 16-second period. That’s proper groundswell energy. The combined energy is moderate at 564. Best of all? Glassy conditions with a light NW breeze. This is going to be clean. The long period will make for some nice, lined-up waves at this reef setup, though it might be a bit more walled-up on the take-off. Expect some good ones, but don’t be surprised if it’s a little straight.
Sunday the 16th has a similar story. Morning starts a bit onshore at 6 mph, but the afternoon glass-off is back. Same 3ft to 4ft SSW swell with that lovely 16-second period. Afternoon looks like the call.
Monday the 17th morning has glassy 3ft SSW swell, again with a decent 14 to 15-second period. Worth a paddle if you can get there early before it gets a bit cross-on in the afternoon.
Now, here’s the rub. From Tuesday the 18th all the way through till late in the month, we’re looking at a stretch of cross-onshore winds. Swell stays small, mostly in the 1ft to 3ft range, but the energy is there. The issue is the wind. It’s going to be bumpy and choppy. Not the quality we’re after. That run goes for over a week.
Things get interesting again around Wednesday the 26th of August. A new pulse of swell arrives, this time from the NW, but it’s short-period windswell at 8 to 9 seconds. The size jumps up to 6ft to 7ft, and the combined energy is strong, hitting 879. But that wind… still cross-onshore. At this size and with that period, these waves will be lumpy, fat, and hard to love. It’s going to be a battle against the chop for a wave that closes out.
The real standout, however, might be Thursday the 27th afternoon and Friday the 28th morning. We’re looking at solid 7ft to 8ft NW swell with a 9-second period. The combined energy is very strong, over 1000. This is big, powerful stuff, but it’s also right at that expert-only level. If the wind co-operates even a little, it could be a heavy, hollow session for the few who can handle it. But again, that cross-onshore wind is going to be a constant companion.
Honestly, for the majority of this 16-day window, the conditions just aren’t lining up for a classic session. Too much wind messing up what could be decent swell. The kite crew might enjoy some of those bigger, blowy days, but for a paddle surfer, it’s looking like a few early morning glass-offs in the first weekend are the best bets, and even then, the long-period swell can be a bit tricky.
Keep an eye on that last week of August, but don’t get your hopes up for perfection.
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.
