Waimea Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let's get into what's cooking for the next couple of weeks.

Right now, it's pretty quiet. The water temp is about 80°F, which is right on the money for this time of year, so no need for a wetsuit.

We've got a slow start, but it builds. The first real action kicks off on Wednesday morning the 19th of August. There's a tiny bit of swell, but nothing special. The real story starts Thursday the 20th. We've got a long period SW groundswell with an 18-second period. That's a proper groundswell, meaning better shaped waves and more energy, but with longer waits between sets. The wind is glassy, which is a huge plus for clean conditions.

The pick of the early window is Friday the 21st of August. We've got glassy conditions, light winds, and a clean 2ft of SSW swell. The combined energy is moderate (250), so it's not a monster, but it's clean and fun. The break is Waimea Rivermouth, which is exposed to the south and works best on a south swell. It's a fairly consistent beginner-friendly spot, but crowds can show up sometimes. This is a solid option for a quiet session.

The weekend of the 22nd and 23rd brings a change. The swell direction swings to the east, and the period drops to 7 seconds. That's short-period windswell, so the waves will be a bit lumpier and less organized. The height picks up to 4ft to 5ft. The combined energy climbs into the moderate range (400-375). It's clean, but don't expect the same quality as the groundswell earlier. Monday the 24th holds similar, with east swell at 5ft and a 10-second period, which is a bit better.

Then there's a lull mid-week, with the swell dropping right back down on the 26th. But don't sleep on Wednesday the 26th of August afternoon. The combined energy jumps to 518 (moderate), with a long period 18-second S swell. It's a solid, clean punchy groundswell again. A real standout for the second half of the week.

The real fireworks are looking like they could be in the second week. The morning of the 29th of August sees a 6ft east swell, combined energy at 624 (strong), and clean conditions. The afternoon jumps to 7ft, energy at 639. That's a big, powerful east swell, but at 7ft, it's getting into expert territory. The period is a short 7 seconds, so it's a windswell, but with that much energy and clean wind, it could be a wild ride. The 31st of August and the 1st of September also hold solid east swell in the 5ft-6ft range with moderate to strong energy.

Remember, this is a long-range forecast. The second week is promising, but less certain. Keep an eye on it.

So, to sum it up: Friday the 21st of August is your best bet for a clean, fun, glassy session. If you're after size and power, look to the 29th of August, but that's for the experienced crew.

Stay salty, and I'll see you out there.
