Alright, Rusty here with a look at what’s on the cards for A-Bay. Straight up, it's going to be a real test of patience for the first week or more. We’ve got a long stretch of flat or barely-there conditions coming our way.
The first decent sign of life doesn’t show up until the afternoon of Monday, July 13th. That’s over a week away of poor surf. On that Monday afternoon, we finally get a bit of wave energy (97 combined energy), with a tiny 1.3ft WNW groundswell, but the real story is the glassy conditions with a light westerly. It’s surfable, but very ordinary.
Now, the standout window is the afternoon of Tuesday, July 14th. The swell bumps up to 2.3ft from the west, with a very long 19-second period (343 combined energy). The wind goes glassy from the northwest. That’s clean, long-period groundswell hitting the reef and point. For A-Bay, with that long period, the point side will be handling it better than the beach. It’s not huge, but for this stretch, it’s the best wave we’ll see.
The following morning, Wednesday the 15th, has similar-sized swell (2.6ft, 16 seconds) but a light cross-onshore breeze. The afternoon glass-off on Wednesday looks good again, with the same 2.6ft swell. Thursday the 16th stays glassy but the swell drops a fraction.
After that, it fades back into small, weak stuff for the rest of the run. The water temp is about average for the time of year, so no surprises there.
Overall, if you’ve got a window, target the afternoon of July 14th and maybe the 15th. The rest is a flat spell.
