The Lowdown
Right, Rusty here, and we've got a frustrating 16 days ahead. The only spot in the game is James Kealoha Beach Park, a reef that's open to the swell.
For the first week and a half, it's a grind. We've got short-period ENE swell fighting us, and the wind is mostly a nasty cross-on or onshore. The swell energy ramps up from a moderate level to a strong one, but it's all blown out and messy. Water's around 81°, which is about normal for this time of year.
A real change comes on Wednesday, September 9th. That afternoon, a light cross-offshore breeze from the ESE finally cleans things up. We get a 6ft NE swell. The period's short at 8 seconds, and the energy is moderate, but after all that chop, clean waves are a life-saver.
Thursday the 10th and Friday the 11th of September give us clean faces from a strong cross-offshore wind, with the swell around chest-to-head high. But the wind cranks to 19 mph on Friday, which means it's getting more interesting for kite-surfers than us paddlers.
For the best call, look at Sunday, September 13th. In the afternoon, we get a glassy 5ft E swell with a light cross-offshore breeze. It's not huge, but the break is *fairly consistent*. For a beginner-friendly reef, that's a quality session, though expect a few others in the water as crowds are *sometimes* an issue.
Bottom line: wait for Wednesday the 9th afternoon or Sunday the 13th afternoon. The rest is a wash.
