The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next few weeks at No Pass. Gotta be straight with you – it’s a mixed bag, and we’re gonna be hunting for the clean windows.
The overall pattern is one of on-and-off, small, long-period SSW swell, but the wind is the real story here. It’s mostly cross-onshore, and that’s going to mess up the surface more often than not. Water temp is sitting around 58°F for the first session, which is pretty much normal for this time of year, so no surprises there.
We start off on Wednesday the 19th of August. The swell is a small 3ft from the SSW with a very long 15-second period, giving us moderate energy (645). The wind is light cross-onshore from the NW though, so it’s going to be a little bumpy. It’s a reef break, and that long period groundswell loves a reef, but the conditions are just marginal. Honestly, not the one to get excited about.
Thursday the 20th and Friday the 21st are more of the same story – small 3ft to 2ft SSW swell, still with that long period, but the wind stays cross-onshore or onshore. The wave energy drops from moderate (516) down to weak (336). It’s just not doing it for me.
Then we hit a rough patch. Saturday the 22nd is a write-off. The swell drops to 2ft and the wind is onshore turning to a moderate cross-onshore in the afternoon. Poor conditions. The 23rd of August, Sunday morning, sees a jump in size to 5ft, but it’s a short-period NW windswell of only 7 seconds, and the wind is cross-onshore – it’s going to be a choppy mess. But hold on, Sunday afternoon is a real standout. The wind goes glassy, dead calm, with a 5ft NW swell at 8 seconds. The energy is moderate (505). This is the one to circle. Clean, glassy conditions on a reef break with a decent little swell. That’s the best we’ve got in the first week.
Monday the 24th and Tuesday the 25th drop back to tiny 2ft to 3ft SSW groundswell, with periods around 16-18 seconds. The wind is glassy or light onshore at times, giving us some clean but very small waves. Good for a longboard or a log, but not much push.
Another little gem pops up on Wednesday the 26th of August. It’s a tiny 2ft SW groundswell (16 seconds), but the wind goes dead calm in the afternoon – glassy. For a small wave, that’s as good as it gets. And again on Thursday the 27th of August, the afternoon goes glassy with a 6ft NW windswell (6 seconds). That’s a bit bigger, but short period, so it’ll be a bit bouncy. Still, on a glassy reef, it’ll be fun.
Now, the second week gets a bit wild. From Friday the 28th of August through to Tuesday the 1st of September, the wind picks up strong from the NW, 12 to 19 mph, cross-onshore. The swell gets a bit of size – 4ft to 7ft – and the energy readings get strong, hitting 1109 and even 1226. But the wind is going to ruin it. It’s going to be choppy and lumpy. This setup is honestly more interesting for kite surfing than paddle surfing. The conditions are poor for a surfboard.
We do get a couple of late bright spots. On Wednesday the 2nd of September, the morning is a tiny 2ft, but the afternoon goes glassy again with a 2ft SSW groundswell (16 seconds). Clean, small waves. And then on Thursday the 3rd of September, the afternoon is glassy with a 2ft NW groundswell (16 seconds). Another clean little session.
So, the real standouts are the glassy windows: Sunday the 23rd of August afternoon, Wednesday the 26th of August afternoon, and Thursday the 27th of August afternoon. The first one has the best size at 5ft, so that’s your best bet. The later ones are smaller but still clean. The rest of the time, you’re fighting the wind.
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.
