The Lowdown

Alright, surfers, Rusty here. Let’s get straight into it for Japs Cove.

Look, I’ve gotta be honest with you – this 16-day run is a bit of a dud for a paddle. The swell is tiny, the winds are mostly messy, and the guidance is telling the same story. We are looking at small, weak SSW-SW groundswells, but the problem is the wind just won’t play nice. The wave energy here is all in the weak to moderate range, so nothing is going to have any punch.

Japs Cove is a tricky little reef setup for advanced surfers only. It’s inconsistent, which is not unusual for a spot this sheltered. The water is much warmer than usual for this time of year at 72.7°, which is a noticeable 3.5° above the norm – a real anomaly. But that’s the only highlight.

Starting off this Tuesday, the 8th, we have a rain shower and a cross-shore wind at 15.5 mph. The swell is a pathetic 1.6 ft from the SSW with a period of 13 seconds. The combined energy is weak at 230, and it’s described as poor surf conditions. Zero out of ten. It’s grim.

The whole first week is a write-off. Wednesday, Thursday, Friday, Saturday – you name it. Swell heights bobble between 1.0 ft and 2.6 ft, but every session has a cross-shore or cross-onshore wind. The period gets up to 17-19 seconds on a few occasions, which would be lovely groundswell, but it’s so small and poorly directed that it’s just not worth the paddle. The wave energy peaks at a moderate 329 on Thursday the 10th, but the wind on the afternoon is SSW at 6.2 mph, which is onshore, making for a sloppy mess.

The second week doesn’t get much better. The swell tries to hold in the 1.6 ft to 2.6 ft range, but the wind remains stubbornly cross-onshore from the SE or WSW. There’s a slight spark on Monday the 21st morning with the swell at 2.6 ft from the SW and a near offshore wind from the SSW at 3.1 mph. The energy climbs to a moderate 383, which is the strongest in the whole period. But it’s still a small wave, and Japs needs more size to be any fun. The rest of that week is more of the same: cross-onshore breezes and mediocre waves.

Honestly, if the swell was bigger, the constant cross-winds and choppy conditions would make this spot look more interesting for kite surfing. But for a paddle surfer, there is genuinely nothing to get excited about here. This is one of those blank runs that can happen here; the forecast will change eventually, but don’t hold your breath on this run.

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.
