The Lowdown

Alright, surfers, Rusty here with the long-range outlook for Japs Cove. Let me tell you, this one's a bit of a tough read if you're itching to paddle out. The water's hanging in at a balmy 75°, which is a solid 9° warmer than usual for this time of year – that's some seriously tropical bathwater, way above normal.

Right now, through the end of August and into the first week of September, it's a write-off. The wind is mostly onshore or cross-onshore, and the swell is tiny, with weak energy levels (around 128 to 247). The reports are all calling it poor surf conditions. It's a long stretch of flat, choppy nothingness.

We get a little flicker of hope on the morning of Saturday, September 5th. A light onshore breeze from the southwest and a 3 ft swell from the SSW, with a 16-second period, giving a moderate energy reading of 457. But it's still being called marginal, so don't get your hopes up too high.

Now, the Sunday afternoon of September 6th is where things get interesting. The wind swings around to a clean offshore from the NNE at 16 mph, and the swell pushes up to 4 ft from the south, with a 15-second period. The combined energy climbs to a strong 768, and it's flagged as "expect good surf conditions." That's a solid window for a surf.

The highlight of the whole forecast, though, is the Monday morning of September 7th. The wind is a gentle offshore from the NNE, the swell is a clean 5 ft from the south, with a 14-second period, and the energy is pumping at a very strong 1112. It's tagged as "expect very good surf conditions." This is the one to circle on your calendar. The swell is getting a bit solid for beginners, but it's a welcome sight.

After that, it's a bit of a rollercoaster. Tuesday, September 8th, has a fresh offshore breeze in the morning pushing a 6 ft south swell, but the period drops to 11 seconds, and the conditions are only called "marginal." The afternoon flattens out again. From Wednesday, September 9th, onwards, it's back to the same old story: poor surf, small swell, and messy winds. The energy drops right back down to weak levels (from 93 to 323) for the rest of the run.

So, take it from me: the one true standout is that Monday morning, September 7th. It's not a perfect forecast, but it's the best we've got by a long shot. The rest of the time, you might as well save the wax.

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.
