The Lowdown
Alright, surfers, Rusty here. Let’s have a look at what’s shaping up for Joss Bay over the next couple of weeks.
Honestly, I gotta be straight with you – this is a tough one. The whole 16-day window is a blank run. There’s just no good surf on offer. The waves are too small, or the wind is a mess, or both. We’re looking at a real flat spell.
The first few days are a write-off. Friday the 17th through the weekend, we’ve got tiny, weak swell, mostly under 2ft, coming from the NNE. The wind is onshore or cross-shore, making it choppy and bumpy. The combined wave energy is pathetic, barely cracking 100 (19). It’s not worth paddling out for.
The pattern keeps up. Monday the 20th, Tuesday the 21st, there’s no change. Just a continuation of knee-high slop with poor winds. You’d be better off finding a fish to talk to.
Then, around Wednesday the 22nd, something interesting happens for a moment – the wind goes light offshore from the SW, and the water is clean. Problem is, the swell is absolutely tiny, only 1ft. It’s glassy, but there’s nothing to ride. The water temp is a notable 68°, which is much warmer than normal for this time of year, but that’s not much comfort when you’re floating on a lake.
The next week, from the 23rd to the 29th, is more of the same. We get a few pulses of energy, like on Thursday the 23rd afternoon when the swell bumps up to 3ft from the NNE and the combined energy hits 138, which is at least moderate. But the wind is terrible, straight onshore, making it a messy close-out. On the 26th, we get some strong offshore winds, but the swell drops to 0.7ft. It’s clean, but you can’t surf it.
Towards the end of the run, on the 31st of July and the 1st of August, we finally see a consistent offshore wind pattern settle in. The swell is still small, around 3ft to 4ft, but it’s clean. The combined energy is moderate (109 on the 31st morning). It’s the best of a bad lot, but for a spot like Joss Bay, which is already inconsistent, a run like this is pretty normal. With the small swell and clean conditions, this setup might actually look more interesting for a kite surfer than a paddle surfer.
So, the outlook is grim. No standouts, no hidden gems. Keep your board in the car and wait for a better forecast.

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.
