The Lowdown
G’day, I’m Rusty. Look, I’ll be straight with you – this is one of those outlooks where you might wanna take up golf for a couple of weeks. The whole 16-day window is a write-off for decent surf at Waiehu Beach Park. Every single session from Thursday 13th August right through to Friday 28th August gets a big fat zero. That’s over two weeks with nothing worth paddling out for.
The winds are pretty much stuck in a cross-onshore groove the whole time, and that keeps the surface messy – choppy, lumpy, just plain ugly. Even when the swell tries to pump up a bit, it’s all wrong. Friday 15th August morning has a 10ft swell from the east with a 10-second period and a combined energy of 1620 (that’s strong energy), but the cross-onshore wind is 19 mph and the whole thing is labelled “poor surf conditions”. That kind of size and power is only for experts anyway, and with those winds, it’s more likely to be a washing machine than a surf session. For the kite surfers out there, that Saturday setup with strong cross-onshore wind and lumpy conditions might be your ticket – but for us paddle surfers, it’s a solid pass.
Water temp is about average for this time of year, nothing unusual there.
There are a couple of mornings around Wednesday 19th and Friday 21st August where the swell drops to 3ft with light breezes, but the period is a short 7-8 seconds, the energy is weak (127-143), and it’s still cross-onshore. Just not worth the effort.
For any beginner thinking of paddling out – on the rare occasions the swell gets over 5ft, like Friday 15th and Saturday 16th, it’s gonna be too big for you, and with those winds, it’ll just be messy.
So, I’m sorry, but there’s nothing to get excited about here. Forecasts do change, and it’s a consistent break, so it won’t stay poor forever – but right now, it’s a hard no.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Waiehu beach park may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
