The Lowdown
Alright folks, Rusty here. Let’s break down what North Bar is serving up for the next couple of weeks. I gotta be honest, it’s a pretty lean stretch, with a lot of flat, wind-chewed days to sort through. The start of the period has the best look, but even then, it’s no hero.
We kick off on Tuesday, the 18th of August, with a small, clean window. The morning is glassy with a light NE breeze, and the water temp is about 72°, which is normal for this time of year. The swell is a modest 3ft out of the SSE, with a short period of 7 seconds, and the combined energy is moderate (102). It’s surfable, but very ordinary. The afternoon cleans up with a gentle offshore from the SW, though the swell drops a little. It’s a longboard or funboard session, just to get a paddle in.
From Wednesday the 19th through to the end of the month, it’s a rough patch. The swell drops right off, the wind turns onshore or cross-shore, and we get a string of days with poor surf conditions. There’s a gap of over a week where you’re really not going to find anything worth paddling out for. The energy is weak, and the wave heights just can’t get it together.
The one real standout in this whole outlook sneaks in on Friday, the 28th of August. The afternoon session is the pick of the bunch. We’re looking at a clean 5ft swell out of the south, with a 9-second period. The wind goes light and offshore from the SSW, which is going to put some nice lines on it. The combined energy jumps up to a solid 390 (moderate-strong), giving it some real push. This is the best wave of the forecast period. It’s a solid intermediate level, so the bigger sets will be too much for beginners. The crowd factor is "sometimes," so you might have a few others out, but with conditions this good, it’ll be worth sharing.
The following Saturday morning, the 29th, gets wrecked by a moderate cross-onshore wind, making it choppy and messy. The rest of the run into early September is a mix of onshore slop and small, inconsistent energy, with a few hints of very long-period, clean but tiny groundswell. Nothing to get excited about.
So, bottom line: if you’re keen, make the call for Friday the 28th afternoon. That’s your window. The rest is a bit of a write-off.
Rusty.

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