The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next 16 days for Japs Cove are a tough watch. This is a sheltered reef setup that only works on a very specific SSW swell, and unfortunately the stars just aren’t lining up. Most of the period is plagued by poor surf quality and inconsistent, small swell. There’s a real gap of clean, rideable waves that stretches for days. Let’s break it down.
We start on Monday the 24th of August with nothing worth paddling for – just 1ft of weak, long-period SSW groundswell (231 combined energy), clocking in at a very long 18 seconds. That’s a classic sign of a drawn-out, straight-breaking wave at this kind of spot, and with a light cross-onshore breeze, it’s messy. The water is a noteworthy 73°F, which is a full 6°F warmer than usual for the time of year – very unusual, feels like a bath.
Tuesday the 25th is much the same story. A tiny 2ft SSW swell with a 16-second period on the morning glass-off, but the forecast calls it “poor surf conditions” and the scores back that up. The afternoon sees a moderate cross-shore wind chopping things up even more.
Wednesday the 26th through to Friday the 28th all blend together into a frustrating stretch. Swell height hovers around 2 to 3ft, but the period drops into the 10 to 13 second range, and winds are either cross-onshore or onshore. Every session gets a zero score – meaning no quality waves to be found. The combined energy stays moderate (between 171 and 281), but it’s just not enough to overcome the bad wind alignment for this sheltered reef.
The first and only flicker of hope comes on Saturday the 29th of August. For the morning session, we see a 3ft SSW swell with a 17-second period, combined energy jumping to 433, and the wind goes light offshore from the SSW. The forecast calls it “marginal surf forecast or questionable tide conditions,” which is the best we’ll see in this entire run. It scores a 1 out of 10. If you’re desperate and you know the reef, this might be worth a look at the right tide. But it’s an inconsistent break that rarely turns on, so don’t expect much.
Sunday the 30th through to Monday the 8th of September is just a long grind. Swell sizes bob around 2ft to 3ft, but winds are almost always cross-onshore or onshore, and the scores stay at zero. The period from September 1st onwards does see a slight uptick in swell height to 3-3ft, and the combined energy regularly sits in the moderate to strong range (300 to 643), especially around the 4th and 8th of September. But the wind is never clean and offshore – it’s always a cross-onshore breeze, ruining the surface for this sheltered break. The water temperature anomaly is unknown for the rest of the period.
Thursday the 5th of September afternoon offers a small chance with 3ft SSW swell and a light onshore wind, scoring a 1 out of 10 – marginal at best. Monday the 7th of September morning also gets a 1 out of 10, with 3ft S swell and light cross-shore wind, but again, it’s a marginal call.
In short: Japs Cove is a very picky break, and this 16-day stretch is almost a total blank. The consistent conditions that produce decent surf just aren’t here. The only real standout – if you can call it that – is the morning of Saturday the 29th of August. That’s your best bet of the window. Take it or leave it.
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.
