The Lowdown

Alright, this is Rusty. Let's get into it.

Alright, so for the next couple of weeks, it's a bit of a mixed bag here at James Kealoha Beach Park. We've got some swell on the way, but the wind is gonna be a constant battle. It's not going to be a total write-off, but you've gotta pick your moments.

The first real chance for a wave comes on Monday, July 20th, but it's nothing to write home about. We're looking at a weak 4ft swell from the east, with a short period, and a light cross breeze. The combined energy is pretty weak (171), and the report says "poor surf conditions." Honestly, it's a skunk session.

Tuesday the 21st is a bit more promising size-wise, with 5ft from the east, but the wind is still a cross-breeze, and the energy is moderate (369). The morning and afternoon are both rated as "marginal." You might get a few, but it's not going to be pretty.

We get a bit of a long-period pulse on Wednesday the 22nd, with a 12-second period from the east, but the wind turns cross-onshore, chopping it up. The energy is moderate (465), but the quality is poor. Not the day.

The rest of the first week and into the second is a similar story. We see a few pulses of energy, like on Saturday the 25th afternoon where the energy jumps to very strong (1020) with a 17-second period, but it's a cross-onshore wind and the report says "marginal." The same goes for Sunday the 26th, where the energy hits (1746) and (2212) with a 16-second period, but again, moderate cross-onshore breeze. For a reef break like Kealoha, that long period groundswell is good, but the wind is the enemy.

The best looking window in the whole 16-day stretch is shaping up for Wednesday, July 29th. The swell is a solid 8ft to 8ft from the NE, with an 11-second period, and the energy is very strong (1720). The key here is the wind lays down to a light breeze, and it's a cross-onshore, which is the best we're going to get. The morning and afternoon both get a "marginal" rating, but given the size and the lighter wind, this is the standout. The water temp is about 80°F, which is pretty normal for this time of year.

After that, the swell drops right off. From Thursday the 30th through to the end of the outlook, we're back to small, weak swell with cross or cross-onshore winds. The energy drops back to the 200-600 range. It's a lot of "marginal" and "poor" calls.

So, if you're looking for the one real window, circle Wednesday, July 29th. It's not perfect, but with that size and the wind as light as it's going to be, it's the best on offer. The rest of the days are a gamble for a few grovelly ones.
