Waimea Rivermouth Surf Forecast and Surf Report

Alright, let's get into it. This is a 16-day look for the Waimea Rivermouth.

First off, we've got a slow start here. The first couple of days are tiny, with swell around 1 ft to 2 ft. The water temp is sitting at 80°, which is about average for this time of year, so the wetsuit’s staying in the car. The real story starts to build from the 17th onward. The wind is looking pretty good for this spot, mostly light and offshore or cross-offshore, which is going to keep the waves clean.

The standout stretch kicks off on the morning of Friday the 18th. We're looking at a solid 3 ft of SSW groundswell with a long 17-second period, and the combined wave energy is pumping at 899 (moderate wave energy). That long period means proper, lined-up waves, but because it's a rivermouth setup, it should handle that nicely. The wind is a clean cross-offshore from the East at 9 mph. This is your best bet in the first week.

Then, hold on for the 22nd and 23rd of September. The swell jumps up to 6 ft, coming from the East with a period around 8 to 10 seconds. The energy is up there at 639 on Wednesday morning. That size is getting into the fun zone for most experienced surfers. The wind stays clean and cross-off. This is the other big highlight, offering some punchy, workable waves.

There’s a little hiccup on the afternoon of the 23rd when it drops right off to 2 ft, but it picks right back up on the 24th with more 5 ft East swell. The last few days of the month see it drop back down to the 2 ft to 5 ft range with clean conditions, so there’s plenty of rideable surf right through to the end. The 28th and 29th get a bit tricky with the wind turning onshore from the South, making things choppy on the 29th, so that's the one to skip.

Overall, for a beginner-friendly spot, the standouts are Friday the 18th for that long-period glass and the 22nd through 24th for the bigger, punchier east swell. Don't sleep on it.
