Kahalu'u Surf Forecast and Surf Report

Alright, this is Rusty. Let’s talk about what’s on the menu for Kahalu'u over the next couple of weeks.

Right off the bat, it’s a slow start. The surf is small and the conditions are a bit average for the first week and a half or so. The real standout window is at the end of the run, and it’s promising enough to keep an eye on.

For Wednesday the 15th, the morning is a write-off. The swell is weak at 3ft from the WNW, but the wind is cross-on and choppy. The combined energy is only 468, so there’s not much push. The afternoon cleans up nicely though – the wind goes light cross-off, the swell bumps to 3ft with a very long 16 second period, and the energy climbs to 529. It’s clean, but still small. Thursday the 16th and Friday the 17th are pretty marginal. The swell drops and the wind is onshore or cross, so the face is messy. Small waves, nothing to get excited about.

The weekend of the 18th and 19th is flat and weak. Swell drops to 1ft to 2ft, and the energy is low (250-286). The water temp is about average for this time of year, so no drama there.

Monday the 20th afternoon is a brief bright spot. The wind goes glassy – perfect conditions – and the swell is 3ft from the south with a 15 second period. The energy is 433, and it’s described as good surf. That’s a nice little session if you can sneak out.

Things get a bit more interesting around Wednesday the 22nd morning. The swell is only 2ft, but the period hits 24 seconds – that’s a very long period groundswell. The energy is 599, so there’s some pulse. For a reef break like Kahalu'u, that long period should wrap in nicely, making for some lined-up, clean waves. The wind is a light cross-shore, so it’s rideable. This is a solid option for the experienced surfer who knows the reef.

The real standout, though, is Saturday the 25th afternoon. This is your best bet. The swell bumps to 4ft from the SSW, with an 18 second period – classic groundswell. The wind goes glassy, dead calm. The combined energy rockets to 900. That’s a solid, clean, powerful swell at a beginner-friendly reef break. It’s going to be the best waves of the whole forecast. Because it’s Kahalu'u, it can get crowded, so get out there early or late.

After that, the last few days of July and into the 30th, the surf drops back down to knee-to-waist high, with marginal conditions and onshore winds. Nothing to plan around.

So, if you’re waiting for a session, hold out for Saturday the 25th afternoon. That’s the one. The Monday afternoon the 20th is a backup, and the Wednesday morning the 22nd is a wildcard for the long-period swell but only for the skilled crew.
