The Lowdown
Alright, Rusty here again. Let’s be real – this 16-day forecast is a total bummer. Anaehoomalu Bay (A-Bay) is a consistent reef and point, but the ocean is giving us nothing. Not a single session worth paddling out for. The water is about 82°, which is normal for this time of year, so no surprises there.
From Saturday, August 29, it’s a joke – a 0.3ft SW swell with a 18-second period, but energy is weak (12) and the wind is cross-on. Just a ripple. Sunday and Monday are flat and glassy. Tuesday, September 1st, a tiny 0.7ft W swell shows up, but it’s cross-shore and messy. Wednesday and Thursday are the same – 0.7ft to 1ft, weak energy (7-9), and poor conditions.
Friday, September 4th brings a little bump: 2ft NNE swell, period only 6 seconds, energy still low (33), and cross-shore chop. Not worth it. After that, it’s a dead zone from the 5th to the 8th – flat, glassy, nothing. A few 1ft SW pulses around the 7th and 9th are weak (energy 33-36) and the wind is never right.
The biggest “event” is Saturday, September 12th: a 2ft SW swell, 8-second period, energy hits 100 – the only moderate pulse in the whole 16 days. But it’s cross-onshore, short-period, and weak. Not enough. The rest is tiny, glassy, and flat.
This is a full 16-day stretch of poor surf. Kite surfers might find something in the wind, but for paddle surfing, it’s a blank run. The break is consistent, but the ocean isn’t playing ball. Forecasts can change, so keep watching, but right now, don’t get your hopes up.
Rusty.
