The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the next 16 days at Joss Bay are a total write-off. There’s not a single decent wave on the cards. The whole stretch from now through to the 2nd of September is a flat, blown-out mess. We’re talking about a solid two-week gap with no surf to speak of.
The first few days, the 18th through the 20th, you’ve got tiny 0.3ft to 0.7ft dribbles out of the north and northeast, with the combined swell energy barely registering (1). The wind is offshore, so it’s clean, but there’s just nothing to ride. Come the 21st through the 24th, the swell tries to bump up a little, hitting 3ft on the 22nd, but it’s all short-period, onshore slop. The energy climbs to a measly 48, still weak, and the wind is cross-onshore, making it choppy and lumpy. Honestly, the setup looks more interesting for kite surfing than paddle surfing.
The water temperature is sitting at 71°, which is a whopping 7° warmer than normal for this time of year – very unusual, but it won’t help the waves.
The rest of the period, from the 25th of August right through to the 2nd of September, is just more of the same. Tiny 0.3ft to 2ft waves, poor energy, and winds that are mostly cross-onshore, onshore, or just plain flat. There’s no stand-out, no hidden gem, nothing. If you’ve got a board, leave it at home. This is a blank run, and for this area, it’s not unusual when the weather patterns lock in like this.
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.
