Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

To be straight with ya, the whole 16-day window is a bit of a dud. We’ve got a big gap right at the start with nothing worth paddling out for, and honestly, the whole run looks pretty grim. There’s a solid block of onshore and cross-onshore winds from the ENE that just won’t quit, and the swell is mostly short-period, wind-driven stuff. It’s a long stretch of poor surf conditions, so if you’re itching for a wave, you might be better off tuning in again next week.

The first real stretch of surf we see kicks off on Friday the 10th of July, but it’s a bust. Kailua Beach is showing a 6ft swell from the ENE with a short period of 7 seconds, and a fresh breeze from the ENE is blowing straight onshore. The combined energy is moderate at 348, but it’s all wind chop – no shape, no joy. That theme is gonna stick around for the whole weekend and into the start of the next week. The water temp is about 79°, which is pretty much average for this time of year, so at least you won’t be cold while you’re getting frustrated.

By Tuesday the 14th, the swell drops a bit to 5ft, but the wind is still onshore, so it’s not cleaning up. The brief window of slightly lighter winds mid-week doesn’t save it because the swell is small and the period is still a short 7 seconds. The energy drops into the moderate range (around 254), but the quality is poor.

We get a little bump in size around Saturday the 18th and Sunday the 19th, with the swell hitting 7ft from the ENE, but the wind is cross-onshore and the period is still short. The energy climbs into the moderate range (477), but it’s lumpy, choppy, and messy. This is the kind of setup that’s more interesting for kite surfing than paddle surfing – the beach break is just gonna be a washing machine.

The very end of the forecast, around Wednesday the 22nd and into the 25th, shows a weird little spike in period – 14 seconds on the 22nd – but the swell is tiny (2ft to 2ft) and the wind is still fresh and cross-onshore. The energy is moderate (357), but that long period groundswell is too small to do anything useful, and at a beach break, it’s gonna break too straight.

There’s no standout here. No day worth chasing. The whole 16-day window is a washout for Kailua Beach. The trade winds are just locked in, and the swell is all short-period and wind-affected. Keep your stick in the car, but don’t hold your breath.

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.
