The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming up for North Jetty.
Right off the bat, I gotta be straight with you – it’s a slow start. We’ve got a long, quiet stretch ahead before anything worth paddling out for shows up. For the next week and a half, from Monday the 17th of August right through to Thursday the 27th of August, it’s mostly small, weak, and pretty ordinary. Lots of days with poor surf conditions. You'll see some weak swell energy, mostly under 100, with heights barely reaching 2ft and short periods – not really doing much. Winds are a mixed bag, but the swell just isn't there. You might find a tiny clean wave on a few mornings, but it’ll be frustrating.
Now, things finally start to change around Friday the 28th of August. We get a bit of a pulse. Thursday afternoon the 27th gets glassy with a small bump, but it’s the Friday that wakes things up. Friday morning the 28th brings in a 5ft swell from the NE, with a moderate energy reading (330) – that’s solid. It’s a bit short period at 6 seconds, but the wind is light and clean. Friday afternoon turns glassy with the swell pushing 5ft and energy up to 398. That’s the first real standout of the forecast.
Saturday the 29th looks like the pick of the run. Morning starts with offshore winds and a 6ft NE swell – period bumps up to 7 seconds, and energy is 381. By the afternoon, it’s 7ft from the NE with a gentle offshore and energy hitting 467. This is proper surf. It’s getting up there in size though – over 5ft means it’s no longer for beginners, and at 7ft, it’s getting into expert territory, especially with that short period making it dumpy. The wind staying offshore is a huge plus for clean waves at this exposed beach/pier setup.
Sunday the 30th still has some decent leftover energy – morning sees a 5ft NE swell with offshore wind, but it’s a step down. By the afternoon, it’s dropping. After that, Monday the 31st and Tuesday the 1st of September fade back into small, weaker conditions with onshore winds creeping in.
The water temp is sitting at 84°, which is bang on average for this time of year – no weird anomalies here. North Jetty is a fairly consistent spot, so this long stretch of nothing is a bit of a drag, but that Friday-Saturday window makes up for it. Just don't be a beginner on Saturday – that one’s for the experienced crew.
Crowds are often a thing here, so expect company on those good days.
This is Rusty, signing off.

Information about the North Jetty Surf forecast
The above surf forecast table for North Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at North Jetty can be found by selecting the local surf guide option on the grey menu. Our North Jetty 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 (North Jetty) 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 North Jetty 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.
