The Lowdown
Alright, surfers, Rusty here. Let’s break down what’s cookin’ for the next couple of weeks.
Honestly, it’s a rough start for Waiehu beach park (Maui). We’re looking at a solid block of poor surf conditions right through the rest of July and into the start of August. The wind is coming from the ENE and cross-onshore, just choppin’ everything up. The swell is around 3ft to 6ft, but it’s mostly short period, weak energy, and that cross-wind is making it a mess. Forget about a paddle for the first week – it’s not worth it.
We do have a bit of a tease around Saturday the 27th of July. The morning sees a pulse of 6ft easterly swell with a 14-second period, and the wind switches to onshore, but it’s still a light breeze. The combined energy is strong (1521), but the forecast is callin’ it marginal due to questionable tide conditions. It’s close, but it’s not a clean winner. The following days, Monday the 28th and Tuesday the 29th, the swell gets bigger – 7ft to 7ft – and the wind turns light and onshore, which is a lot better. The period is droppin’ from 14 seconds to 12 seconds, but it’s still a decent groundswell. The energy is very strong (over 1300 and up to 1688). The problem is the tide and the fact that this is a reef and point break. A long-period swell from the east can run straight at a point, but it can also be tricky. For a bigger surfer, this is the window. The best morning looks to be Tuesday the 29th of July: 7ft from the ENE, 12-second period, and a slight air from the NNE (5 km/h). That’s almost glassy. That’s the standout for the whole forecast. Water’s about 80°F, which is pretty normal for this time of year.
After that, it drops off again. From Thursday the 30th of July through to the 4th of August, we’re back to poor surf and cross-onshore wind. The swell comes down to 5ft and then 2ft, and the energy drops hard. It’s a blank run for the second week all over again.
So, the honest truth: don’t bother for the first week. The best you’ll get is that Tuesday the 29th of July morning. If you’re an expert, the 7ft waves are on the bigger side, but with that light wind, it could be a special session. For everyone else, it’s a miss.
Rusty.

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.
