The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up.
The first few days are a total bust. We’re looking at a gap of nearly a week with nothing to ride. The water temp is about 81°, which is normal for the season.
Finally, on Sunday afternoon, the 6th of September, we get a tiny pulse. Laniakea Reef and Holtons sees a 2ft southwest swell with a long 15-second period. The combined energy is moderate at 206, but it’s only marginal, so don’t rush out. The wind is a cross-off from the ENE at 16 mph, keeping things tidy but the swell is way too small.
Things start to wake up on Monday the 7th. By the afternoon, the southwest swell is 3ft with a 12-second period, and energy jumps to 281. The wind drops to a light 9 mph cross-off from the E, which is clean. That’s the first surfable wave. Tuesday the 8th improves. The morning is 3ft, but the afternoon is the pick: 5ft of southwest swell, 14-second period, and a solid 671 energy. With gentle ESE cross-off winds, it’ll be smooth. Wednesday the 9th holds 4ft in the morning, but the energy is lower and the wind picks up a bit.
The absolute best session is Sunday, the 13th of September. The morning brings a meaty 8ft northeast swell at a 10-second period. The combined energy is a whopping 1185 – that’s serious power. This is expert-only territory, it’s going to be a beast. The afternoon settles to 7ft with 9-second period and 798 energy, and the wind is a gentle cross-off from the E. This is the real deal for the reef, and it’s the standout of the whole forecast. If you’re not experienced, give it a miss.
After that, Monday the 14th drops to 6ft, and the rest of the week fades away. The 16th shows a weird 2ft southwest swell with a very long 19-second period and 269 energy, but it’s rated poor, so don’t count on it.
So, a slow start, but circle the 13th. That’s the big one.
Rusty.
