The Lowdown
Alright, folks. Rusty here. Let’s be real about Joss Bay. The outlook for the next sixteen days is a tough one. There’s a long, empty stretch here, with hardly any surf worth paddling out for. The first decent recommendation doesn’t even show up until the very end of the period, so we’re looking at a gap of nearly two weeks with nothing recommended.
The water temperature is sitting at 68°, which is a whopping 7° warmer than usual for this time of year. That’s very unusual, and you’ll definitely feel that bath-like water if you do get in.
For the vast majority of the forecast, the waves are tiny, the wind is messy, and the energy is weak. The few moments where there’s a little bump of swell, like around the 20th and 23rd of July, the swell is coming from the north or north-northeast with a short period (6 to 7 seconds) and combined energy in the low teens to low forties (43 being the highest in that early window). The wind is onshore or cross-onshore, and the surf is described as poor. Not a single moment in the first two weeks cracks a decent score.
The only real standout, and I mean the *only* one, is at the very end of the run. On the morning of Saturday, the 1st of August, we get a bit of a surprise. The swell is pushing 3 feet from the east-northeast, with a period of 5 seconds. The combined energy is a weak 29, but the wind is a fresh offshore breeze from the west-southwest at 19 mph. That offshore wind is a major positive, and it’ll clean the waves right up. It’s small, but it’ll be glassy and rideable. If you’re desperate, that’s your window. The afternoon gets even windier, with a strong offshore at 25 mph, making it hard to paddle into but still clean as a whistle for the few waves that do pop.
Joss Bay: The only real chance comes on the morning of Saturday, the 1st of August. It’s a tiny 3-foot east-northeast swell, but with a strong offshore wind, it’s going to be clean. Don’t expect much, but it’s the only show in town.
Right, that’s the long and short of it. It’s a tough run, but forecasts can change. Keep an eye on it.
Rusty.

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.
