The Lowdown
Alright, Rusty here. Let’s cut right through it. This 16-day window is a tough slog for Waimea Bay/Pinballs. If you’re sitting on the beach waiting for the North Shore to light up, you’re looking at a real dry spell. For the first twelve days, from August 8th right up until the morning of August 20th, it’s a total bust. The swell barely tickles the reef, with wave heights mostly hanging around 0.7 ft to 1 ft and the energy is weak, often below 50. It’s a long, flat gap. There’s just nothing to paddle into.
The one and only window in this whole forecast comes as a bit of a surprise. On Thursday morning, August 20th, a pulse of swell shows up from the northeast. We’re looking at 4 ft of swell, with a period of 8 seconds. That’s a short period, so the energy (234) is moderate but a bit disorganized, making it better for a beach break feel than a proper point setup. The wind is light from the east at 6 mph, keeping the surface clean. It’s not a classic Waimea day—far from it—but compared to the weeks of flatness, it’s the only game in town. The water temp is sitting at about 80°, which is bang on average for this time of year, so grab the shorty if you get cold easy.
That Thursday morning is the standout. It’s the only day with a score worth mentioning. The rest of the forecast after that drops right back into tiny, weak surf with onshore or cross-off winds. For the next few days, you’ll be looking at ankle-biters at best. So, if you’ve got a window, hit it on August 20th.
Rusty.
