The Lowdown
Hey crew, Rusty here. Let's get into the Joss Bay forecast for the next couple of weeks, and I’m not gonna sugarcoat it – it’s looking pretty grim.
We’re starting off with a proper flat spell. From Saturday the 5th all the way through the next week, there’s nothing doing. Wave heights are stuck under 2ft, mostly just tiny ankle-snappers around 0.3ft to 1ft, and the combined swell energy is pitiful, sitting at a 2 to 5. The wind direction is changing a lot, but it doesn’t matter when there’s no swell to work with. It’s a long dry run for surfers.
There is a little bump in energy toward the very end of the forecast. On Friday the 18th, we get a morning glass-off at Joss Bay (United Kingdom). We’re looking at a 3ft swell from the northeast, but it’s only a 4-second period – that’s super short-period, wind-driven slop, not proper groundswell. The energy ticks up to 29, which is still weak, but the water will be completely flat and clean with no wind. It’ll look pretty, but don’t expect any power or a decent wave face. The water temperature is sitting at 68°, which is much warmer than average for this time of year – about 5° warmer than usual, which is very unusual.
Then on Saturday the 19th, we get another tiny window. A 1ft, 6-second northeast swell with a glassy morning, but the energy drops back down to 11. Clean, but tiny.
So what’s the standout? Honestly, there isn’t one. If you absolutely have to get wet, the Friday morning of the 18th is the pick of a bad bunch. That 3ft glassy session is the biggest we see, but with such a short period, it’s going to be small and soft – strictly longboard or funboard territory. The waves will be mushy and close to the beach with that short period.
Crowds are listed as "often" at Joss Bay, but with this forecast, I’d be surprised if anyone shows up. This is a tough stretch of flatness for the area, just one of those spells you have to weather. Keep checking, things can change, but right now, leave the board in the car.
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.
