The Lowdown
Alright, gonna keep it straight with you. Joss Bay is looking pretty sad for the next couple of weeks. We've got a long stretch of nothing but tiny, weak waves, and the swell just isn't showing up.
Right off the bat, for the first week, we're looking at ankle-biters. Sunday the 30th has a pathetic 0.3ft of swell, and the energy reading is barely a whisper at 1. It's clean with a moderate offshore, but there's nothing to ride. This flatness is gonna hang around for days. Monday and Tuesday have the same story, just 0.3ft with weak energy (1 and 2). The wind is offshore, which is nice, but that doesn't mean a thing when there's no wave.
We finally see a little bump in period on Thursday the 3rd, up to 11 seconds, but the height is still stuck at that useless 0.3ft. The energy ticks up to 4, but it’s still just a ripple. It's a long-period groundswell, but with that size, it's a non-event. We're just staring at an ocean that's way too polite.
The first week is basically a write-off. There's over a week of almost nothing, so if you're desperate for a paddle, bring a floatie.
Now, as we push into the second week, around Saturday the 12th and Sunday the 13th, the size finally starts to show a pulse. We're looking at 3ft to 3ft from the E with energy readings in the 31 to 38 range. It’s more than we've seen, but the wind turns onshore (NE and ENE) with a fresher breeze, so it’s going to be lumpy and messy. Not great, but at least there’s something to look at.
The real highlight of the whole fortnight, if you can call it that, is Monday the 14th. The swell bumps up to 4ft from the ENE with a moderate 5-second period. The energy reading jumps to 62, which is the strongest we see. It's still onshore wind, but the size is there. This is the most interesting it gets for a paddle. It's right on the edge of being fun but it's not going to be a classic. The short, 5-second period means it's windswell, so expect it to be a bit crumbly and sectiony, not a clean point break peel.
But honestly, Joss Bay just isn't doing its thing. This whole forecast is a dull affair. For anyone thinking about it, this new E/ENE windswell on the 14th is the only thing that might get you out of bed. It's not a standout, but it's all we've got, and with a northeast onshore breeze, it might be one for the kites, not the surfboards. Crowds are often an issue here, but on a day like this, you might have it to yourself.
I'll be honest, this stretch looks more interesting for the foilers or the kitesurfers during that second week when the wind is up and the ocean is lumpy. For the rest of us, it's a waiting game.

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.
