The Lowdown
Alright, Rusty here, let’s talk about what’s coming up for North Jetty. To be straight with you, this isn’t a period for the history books. We’ve got a long stretch of small, weak, and often messy surf to get through before anything worth getting excited about shows up.
For the first two weeks, from Thursday the 20th of August all the way through to around the start of September, it’s a real struggle. The swell is tiny, mostly hanging around 0.7ft to 1ft from the ESE. Wave energy is weak, often below 30 (26-57 range). Even when we get a few hours of glassy offshore wind – like Saturday the 22nd afternoon with a 0.7ft ESE swell and a 13-second period – the waves are just too small to bother with. It's surfable but very ordinary. The water temp sits at 86°, which is a touch warmer than normal for this time of year, so the water’s nice, but the surf isn’t.
The first real glimmer of hope comes right at the tail end of the period. On Thursday the 3rd of September, we finally see some size. The morning looks good: a 6ft swell from the ENE, with a short period of 7 seconds, and glassy conditions. Combined energy hits 269, which is moderate, and the wind is calm – that’s a green light. This is big enough for intermediates, but just over 5ft, so beginners might want to sit this one out. The afternoon gets messy as a 12 mph cross-shore wind kicks up, so surf the morning.
That Thursday morning is the standout. The next morning, Friday the 4th, is also a strong option: a 5ft ENE swell (7-second period) with a clean 6 mph cross-offshore wind. Combined energy is 256, again moderate. Get on it early.
Forget the rest of the window. The north coast is quiet for ages, but that first week of September offers a couple of proper dawn patrols. North Jetty is often crowded, so expect company on those clean mornings.

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.
