The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Waiehu beach park. It’s a reef and point set-up, so when conditions line up, it can offer some fun lines. The water’s sitting at 80°, which is pretty much normal for this time of year – nothing unusual there.
Right now, we’re looking at a bit of a flat spell. The first few days are a write-off, to be honest. Monday the 10th through to the end of the first week, the wind is blowing cross-on from the ENE, and the swell is small and short-period. Surf heights are around 3ft to 5ft, but the periods are short (7-8 seconds), and the wind is just making it choppy and messy. The combined energy is weak to moderate (229 to 268), and the wave comment says it’s poor. Not worth paddling out for.
Now, we’ve got a gap of a few days here with nothing to recommend. It’s not until the weekend of the 15th that things start to get interesting. The swell builds, but on Saturday the 15th the wind is still nasty – fresh to strong cross-on, with rain and moderate rain. The swell’s getting up to 7ft to 7ft from the ENE, but it’s still short-period (10 seconds), and the energy is building (740 to 835). Still, the wind is wrecking it, so it’s a no-go.
Here’s the standout. Sunday the 16th of August. For the first time in this outlook, the wind switches to a cross-off from the south, and the swell is building nicely. You’re looking at 8ft to 8ft from the ENE, with a period of 10 to 11 seconds. The combined energy jumps right up to 1115 to 1328, which is strong. The wave comment says it’s marginal due to tide, but the wind is clean. This is the best on offer, and it’s the only real shot at something decent. For a beginner, this size is getting a bit big, but it’s not out of control. The break is consistent, so you can expect waves. The optimum swell direction is NNE, and we’ve got ENE, which is good, but not perfect. The crowds are often there, so expect some company.
Monday the 17th still has some size, 8ft to 8ft, but the wind goes back to a light cross-on from the ENE, which will put a bit of texture on the face. The energy is still high (1174 to 1175), but it’s not as clean as Sunday. It’s a “maybe” if you’re desperate.
After that, from Tuesday the 18th onwards, we’re back to small, weak, and choppy. Swell drops to 3ft to 4ft, periods are short (7-8 seconds), and the wind is cross-on again. The energy drops way down (108 to 281), and the wave comment is poor or very marginal. The run from the 18th through to the 25th is a long stretch of nothing much. The last few days of the outlook, the 24th and 25th, have a bit more size (5ft to 6ft) but still cross-on wind and short period, so it’s not going to be clean.
So, to sum it up: the only real window is Sunday the 16th of August. That’s the one to keep an eye on. The rest of the 16 days is mostly a waiting game. Keep your hopes up, the forecasts can change.
Rusty.

Information about the Waiehu beach park Surf forecast
The above surf forecast table for Waiehu beach park provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Waiehu beach park can be found by selecting the local surf guide option on the grey menu. Our Waiehu beach park surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Waiehu beach park) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
