The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Waiehu beach park.
Honestly, the next week and a half is a bit of a grind. We’ve got a solid stretch of poor surf conditions from now through to the end of July. The wind is stuck in a cross-on pattern from the ENE or NE, blowing at 9 to 16 mph, which is keeping the surface choppy and messy. The swell is mostly small, between 4 ft and 6 ft, with a short period of 6 to 8 seconds, so the wave energy is weak to moderate. It’s just not clean enough to get excited about. There’s a gap of about eight days here where I wouldn’t bother paddling out.
Now, look sharp for the morning of Wednesday, the 29th of July. That’s the standout. We’ve got a 13 ft swell from the east with a 14-second period, and the wind is offshore from the NNE at 9 mph. The combined swell energy is strong. That’s the real deal. It’s a big, powerful groundswell, and with the offshore wind, Waiehu beach park should have some proper, clean lines. But listen, this is a big one – 13 ft is expert territory, and this is a reef and point setup, so those long-period swells will wrap in nicely. The afternoon gets even bigger, with a 20 ft swell and a very strong energy reading, but still with that offshore wind. That is massive, and only for the brave. The morning of the 30th of July still has a strong 10 ft swell from the east with light offshore winds, but the period drops to 9 seconds, so it’s a bit less organised.
The water temperature is sitting at 79°F, which is about average for this time of year, so no surprises there.
So, to sum it up: the first week is a write-off. The real action is on the 29th of July morning and afternoon, and the 30th of July morning, with serious, clean, offshore swell for the experts. It’s a long way out, so keep an eye on it, but the potential is huge.
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.
