The Lowdown
Alright, Rusty here. I’ll be honest with you—this 16-day run for Japs Cove is a total bust. This is a sheltered, inconsistent reef break for advanced surfers only, and the forecast shows nothing worth paddling out for. The first week is a complete write-off, and the second week is a real long shot.
From now through the end of July, we’re looking at tiny, weak swell. The water temp is 70°—that’s *much warmer than normal* for this time of year, nearly 5° above average, which is pretty unusual. But the waves? Forget it. For the first 10 days, it’s 1ft to 2ft of swell from the SSW, with light to moderate side-onshore winds. The wave energy is weak, running from 139 to 341 (moderate energy at best), and the period is long—12 to 18 seconds—so it’s groundswell, but it’s just too tiny to ride. The wave comment is ‘poor surf conditions’ across the board.
Even when the swell nudges up a little around July 22, the conditions don’t get better. The wind is still side-onshore, and the energy climbs to moderate levels like 572 (strong-ish). The period drops to 14 seconds, and the swell shifts to SSE and then S. It’s a bit bigger—2ft to 4ft—but we’re still stuck with ‘poor’ or ‘marginal’ wave comments. The only slight glimmer is on July 24, Friday morning, when there’s a 4ft S swell with a 15-second period and light side-onshore breeze. The energy hits 746—strong—but it’s still not clean. The wind is light, but it’s side-onshore, so it’s choppy. Not a standout.
The best of a bad bunch is July 26, Sunday morning. We’ve got a 2ft swell from the SW with a 19-second period—real long-period groundswell—and the wind is light onshore. The energy is 688 (strong). For a reef break like Japs Cove, that long period can mean nice, lined-up waves, but it’s inconsistent, and the onshore wind will still mess with the face. It’s a ‘marginal’ call. Not something I’d drive for.
Honestly, there’s no standout session here. The gap of good surf is the entire 16-day window. The first 10 days are a waste, and the second week only offers maybe a couple of mornings that are barely worth a look if you’re desperate. This spot is inconsistent at the best of times, and this forecast is a perfect example of a blank run. It’s normal for the area to have long gaps like this. Keep an eye on it, but don’t hold your breath.
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.
