The Lowdown
Alright folks, Rusty here. I’ve got the goods on Joss Bay, and I’m not gonna sugarcoat it: this stretch of the next 16 days is about as flat as a pancake. Right from the start, Friday the 4th, there’s nothing. The wind is howling from the WSW at 25 mph, and the ocean is basically a lake. That sets the tone for a long, frustrating run.
We’re looking at a solid gap of poor surf conditions that stretches all the way from now until the middle of the second week. The swell energy is just non-existent, mostly showing zeros and ones. It’s a tough stretch for a spot that’s already inconsistent, so this kind of blank run is more normal for the area. Don’t get your hopes up for any quick change.
The first real glimmer of anything rideable doesn’t show up until Sunday the 13th. Even then, it’s weak. The morning offers a 3ft swell from the NNE with a short period of 5 seconds, giving us a combined energy of just 33 (weak). The wind is a light NW cross-off, which will keep it clean. It’s not much, but it’s the best we’ve seen in a week. The afternoon lightens up with a 2ft NE swell, period 4 seconds, and a light W cross-off.
The only other day that might get a nod is Wednesday the 16th. The morning shows a 4ft swell from the NNE, still a short 5-second period, but the combined energy climbs to 84 (still weak). The wind is NW at 19 mph, cross-off, so it’ll be clean. This is a long-range call, so promising but less certain. Even then, 4ft is small and weak, more of a longboard or funboard wave for the intermediates. The crowd situation at Joss Bay is often busy, so if you’re paddling out on that Wednesday morning, you’ll have company.
Honestly, there’s no standout here. The whole period is a disappointment. The water temperature is 68°F, which is a massive 5°F warmer than usual for this time of year – that’s very unusual. Just one more thing that feels off.
Keep your boards waxed and hope the forecasts change. This is a quiet one.

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