Right then, let’s have a proper look at what’s on offer. I’m gonna level with you, the next couple of weeks are a bit of a struggle. We’re looking at Rivermouth_Wailuku, a reef setup, and it’s fairly consistent for swell but the wind is just not playing ball. The water temp is 79° with a slight anomaly of 0.5°, so pretty average for this time of year, nothing wild to report there.
From Thursday the 2nd of July right through the entire 16-day run, every single session is getting a cross-onshore wind. Morning and afternoon, day after day. We’ve got swell sizes hanging between 4 ft and 6 ft, coming from the ENE with a short period of 7 to 8 seconds. The combined energy builds from 217 up to a peak of 417 on Tuesday the 7th of July afternoon which is moderate energy (417) but it’s just not clean surf. The wind is either a gentle or moderate breeze and it’s making everything choppy.
There is no standout session. Not one. The wave comment on every record is “poor surf conditions,” and that’s the honest truth. There’s a gap of surf on offer the whole time, but it’s all pretty average. The swell direction is ENE and the optimum for this spot is NNE, so it’s not even hitting the reef right. With that onshore wind and short-period swell, the setup looks more interesting for kite surfing than paddle surfing at this point.
Because the break is fairly consistent, keep the faith – things don’t stay poor forever and forecasts can turn around. But for this outlook, there’s nothing I’d paddle out for.
