The Lowdown
Alright, let me take a good look at what's on offer for Laniakea Reef and Holtons.
Honestly, it’s a pretty flat and frustrating run we’ve got ahead of us. The next 16 days are looking like a write-off for any kind of decent session. The swell is just too weak to get the reef working properly.
We do have a few days with some energy around the 19th and 21st of August. Wednesday morning the 19th will see a weak 0.7m NE windswell pushing in with a period of just 6 seconds. The combined energy is pretty low (112), so it’s small and soft. The wind is a cross-offshore from the east at 9 mph, which will keep the surface clean, but honestly, it’s just not enough to get excited about. The water temp is about average for this time of year.
Thursday the 20th is even weaker, and by Friday the 21st, we get a brief bump in size to 0.9m from the NE in the morning, combined energy up to (113), but still with that same short 7-second period. The wind goes glassy-light in the morning at 3 mph, which is a major positive for a clean surface, but the waves themselves are just chunky and unshaped.
After that, it’s a long, bleak stretch. From Saturday the 22nd right through to the 3rd of September, it’s almost entirely poor conditions. The swell drops away completely, with heights mostly below 0.5m, and the combined energy values are in the double digits—weak at best. The wind stays cross-off but picks up strong, with gusts up to 25 mph around the 24th, and even a risk of thunderstorms that afternoon. It’s not surfable.
Honestly, for a spot like this which is a consistent reef break, this is a really unusual blank run. It just doesn’t stay this poor for long. Keep an eye on the forecasts, because right now there is nothing worth paddling out for.
