Table - best surf conditions forecast for Kailua Beach over the next 16 days.
Alright folks, Rusty here. Gotta be straight with you – this outlook is a tough one. We're looking at a 16-day window for Kailua Beach, and honestly, the news isn't great. The whole period is a bit of a write-off for decent paddle surfing. The wind is the main culprit, and it just doesn't let up.
The problem starts right away and runs all the way through. We've got a persistent ENE wind that's blowing onshore or cross-onshore nearly every single day, from 9 mph all the way up to a fresh 22 mph at times. That's going to chop up the surface and make things messy. The swell is there, but it's not doing us any favours. It's a short-period, wind-driven ENE swell, with periods of just 6 to 8 seconds, and the combined energy is moderate. It's a lot of lumpy, bumpy, weak energy, not the kind of clean, lined-up groundswell we'd want to see for a point break. The water temp is sitting about average for this time of year at 79°.
So, the hard truth is there are no good surf options in this 16-day window. The surf data is consistently reporting "poor surf conditions" and scoring a flat zero across the board. From the afternoon of July 11th through to the afternoon of July 26th, there's not a single window where the conditions line up. The wind is either too strong, coming from the wrong direction, or both. It's a long, blank run.
Given that the wind is so strong and consistent, and the wave quality is poor for paddling, this setup looks a lot more interesting for kite surfing than paddle surfing. The 4ft to 7ft windswell and the steady trade winds will provide plenty of power for a kite. For a surfer, you're better off waiting for a lighter wind day or a proper swell from a better direction. Forecasts can change, but right now, this is a solid miss for the waves.
Rusty.

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