Alright, Rusty here. Let's check the waves.
Honestly, I'm not hyped on this forecast at all. For Waimanalo, from Thursday the 2nd all the way through to Friday the 17th, every single report says "poor surf conditions." That's a full 16-day stretch with no good options.
The water temp is 26°, pretty much dead normal for the season.
The main problem is a brutal onshore wind – out of the ENE at 18 to 25 mph – just tearing across the exposed beach. The swell is short-period junk, 2 ft to 7 ft, coming from the same ENE direction as the wind, which is totally wrong for this spot. Waimanalo likes a nice NE groundswell. All that wind and short-period chop gives us wave energy figures like 292 to 503, but it's all energy you don't want.
With a beach break like this getting hammered by onshore wind, it's honestly a better setup for the kite crew than for us surfers. It's a fairly consistent spot, so there will be waves, but they'll be a total mess. We just have to hope the forecast changes.
Keep your head up.
Rusty.

Information about the Waimanalo Surf forecast
The above surf forecast table for Waimanalo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Waimanalo can be found by selecting the local surf guide option on the grey menu. Our Waimanalo 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 (Waimanalo) 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 Waimanalo 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.
