The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this next 16-day stretch is a tough one for Japs Cove. We’ve got a reef setup that’s sheltered and picks up swell from the SSW, but the numbers just aren’t coming together for a proper paddle session. The whole run is a bust.
Starting from Friday the 31st of July, we’ve got a little pulse of 3ft SSW swell with a period of 14 seconds, but the wind is already messing it up. Light cross-onshore breezes and a combined energy of 285 (moderate) just isn’t enough to overcome the poor conditions. Saturday the 1st of August drops to 2ft, and it’s the same story – light cross-onshore wind, poor surf. Sunday the 2nd of August sees the swell drop to 1ft, and the wind shifts to onshore, which is no good at all. The energy is weak, sitting at 125 (moderate).
We go through a long, flat, and choppy stretch. From Monday the 3rd of August all the way through to Saturday the 15th of August, the swell is stuck between 1.0ft and 2ft, almost always from the SW or SSW. The wind is a constant problem – mostly cross-onshore, with some onshore days mixed in. The combined energy fluctuates between 90 (weak) and 273 (moderate), but the “poor surf conditions” tag is on every single entry. There’s no clean, glassy moment to be found. The best period we see is a 19-second groundswell on Friday the 7th of August, but it’s 1ft and cross-onshore – that’s just a tease.
Truth is, there are no standout days here. The swell is too small, the wind is never offshore, and the waves are too weak to do anything with. For a reef that needs a clean SSW swell, this is a total write-off. If you’re thinking of kiting, the cross-onshore wind might offer something, but for a surfboard? Forget it. This is one of those blank runs that’s more normal for the area when the conditions just don’t align. Hang tight, the forecasts can change.
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.
