Rainbow Bay Surf Forecast and Surf Report

Alright folks, Rusty here. I’ve been staring at the charts for this stretch, and it’s a bit of a slow-burner, but there’s a proper payoff if you’re patient.

Right now, the first week is pretty flat and ordinary. The swell is small, around 2ft to 3ft, with a weak period well under 10 seconds. The combined energy is low, barely getting into the triple digits (165 at best), and it’s mostly from the east or east-northeast—which isn’t the ideal direction for Rainbow Bay. A few mornings offer glassy conditions, like Thursday morning, but the waves are just too weak to get excited about. It’s not until Saturday morning, the 8th, that we see "surfable waves but very ordinary conditions" with a 3ft ENE swell and a clean cross-off breeze. The water temperature is sitting at 69°F, about average for the time of year, so no surprises there.

The real standout, the one you’ve been waiting for, kicks off on Thursday, the 13th of August. This is the gem of the forecast. We’ve got a solid 8ft swell from the SSE, with a period of 9-10 seconds, and the combined energy just jumps into the very strong range (1047-1114). The wind is a moderate offshore from the south, and the forecast calls for "very good surf conditions." This is the kind of day that gets the heart pumping. The swell direction is right on the money for the optimum from the southeast, and that offshore breeze will keep the faces clean and lined up. For experienced surfers, this is a proper session. Beginners, be warned—this is pushing into the “too big” zone.

The excellent conditions roll into Friday, the 14th, with 8ft waves from the south in the morning (combined energy of 1610, the biggest of the run) and offshore winds. It’s big, powerful, and for experts only. The period drops to 8 seconds by the afternoon, but it’s still a solid 7ft. The run continues through the weekend and into the following week with a consistent 5ft to 7ft range from the SSE, mostly under offshore winds. The wave quality holds up as "good" through Monday, the 17th, and Tuesday, the 18th, before it starts to ease off by Wednesday, the 19th.

The only real caveat with this spot, Rainbow Bay, is that it is a point break and it’s "fairly consistent," but it can get crowded. The "often" crowds label means you won’t be alone out there, especially when the swell lights up. That’s just the price of a good wave.

So, the bottom line: the first week is a write-off. Don’t bother. But from Thursday, the 13th of August, through to the following Wednesday, the 19th, this place is on. The standout is definitely Thursday, the 13th, and Friday, the 14th, for the biggest, cleanest, most powerful swell. The long-range stuff is promising, but keep an eye on it as we get closer.

Rusty.
