The Lowdown
G’day, Rusty here. Look, I’m gonna level with you – this forecast for Japs Cove is a real tease. We’ve got one solid window of clean, fun waves right at the start, and then it’s basically a two-week wait for the next real chance. The water is a scorching 72°F – that’s over three degrees warmer than usual for this time of year, which is very unusual. It’s like a bath.
The standout session is hands down Saturday morning, September 5th. Japs Cove is a sheltered reef break, and it’s going to be absolutely glassy with a light SSW wind. We’re looking at a 3ft groundswell from the SSW with a long 16-second period, packing a solid moderate wave energy (602). That long period means the waves will have shape and power, perfect for the reef. It’s an advanced spot though, and it can be inconsistent, so don’t expect a constant barrage. Also, crowds are possible here.
Saturday afternoon goes south quickly – the wind swings cross and the surf quality drops. Sunday morning, September 6th, is worth a look too. It’s clean with a cross-offshore breeze, and a similar 3ft SSW swell at 15 seconds (430 energy). It’s a good backup, but not quite the peak of Saturday morning.
After that, the outlook turns grim. From Sunday afternoon all the way through to Sunday, September 20th, the conditions are mostly poor. The wind is nearly always onshore or cross-onshore, and the swell drops right off. We’re talking about a long stretch of 1.0ft to 3ft junk with short periods and weak energy – mostly in the 100s and low 200s. It’s a real bummer, but that’s the way it is for this spot. The only faint glimmer is Sunday morning, September 20th, where the swell energy climbs back up to 326 and the period hits 19 seconds, but it’s still cross-onshore. Don’t hold your breath.
So, here’s the deal: if you’re an advanced surfer, get on it this Saturday morning. That’s the one. The rest of the month is a write-off for Japs Cove.
Rusty.

Information about the Japs Cove Surf forecast
The above surf forecast table for Japs Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Japs Cove can be found by selecting the local surf guide option on the grey menu. Our Japs Cove 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 (Japs Cove) 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 Japs Cove 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.
