The Lowdown
Alright, surfers, Rusty here. Let’s have a look at the charts for Joss Bay. Straight up, I gotta tell you, this is a tough one. We’re looking at a 16-day window, but there’s practically nothing on the table that’s going to get me excited. The whole run is a flat spell, so don't bother wiping the dust off your board just yet.
The surf starts off small and stays that way. Over the first week, from Tuesday the 11th right through to the 20th, we’ve got tiny, weak waves with barely any energy—the combined swell energy is sitting in the low 20s to single digits (20... 24... 58... 12...). That’s basically flat. Add to that a consistent onshore or cross-onshore wind from the east and north-east, and you’re looking at choppy, poor conditions. Forget about it. There’s a brief moment on the 14th and 15th with crisp offshore winds, but with wave heights of just 0.3 ft to 3 ft and a whopping 4-second period, it’s not even a ripple worth paddling for.
Moving into the second week, from the 21st onward, it only gets worse. For a solid stretch of days, the swell energy drops to a single digit (2, 0, 1, 1). The combined energy is zero on a few occasions. The winds do go clean offshore from the west and southwest on the 22nd, 23rd, and 25th, which is a tease, but the wave height is pitiful—0.3 ft and 0.7 ft. It’s not surfable. Even a period of 6 seconds on the 24th and 26th can’t save it when there's no height at all. You’d be better off practicing your pop-ups on the lawn.
Joss Bay (United Kingdom) is an inconsistent spot, and this forecast is a perfect example of why. If you absolutely have to get wet, the “best” window is tough to pick, but the 22nd of August Saturday morning shows a tiny 0.3 ft of north swell with a gentle offshore breeze, and the 25th of August Tuesday shows 2 ft to 3 ft from the north-east with a moderate offshore wind. But at that size and with that energy (1 or 13), you’re basically floating. It’s not a real surf.
No standouts here. The whole 16 days is a write-off for surf. Patchy, inconsistent, and flat. Sometimes it just be like that in this neck of the woods. Forecasts can change, but right now, there’s nothing doing.
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.
