The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
First off, I gotta be straight with you – the outlook for Kailua Beach is a bit of a bummer for the near future. The swell is coming in from the ENE, which is not the direction this point likes to see. We’re looking at strong to moderate onshore and cross-onshore winds for the first several days, and the surf is just small and messy. The combined swell energy is weak at best, starting at 521 on Friday the 24th, and the conditions are just poor. There’s a lot of chop and lumpy water, and the swell period is short, around 7 to 8 seconds, so it’s not got any real punch. The water temperature is about average for this time of year, nothing to write home about.
We’re looking at a dry spell for a while. The first week is pretty much a write-off. The wind is relentless from the east-northeast, and the wave quality is zero. The best I can see in the first week is a brief moment on Wednesday afternoon the 29th, where the swell picks up to 10ft from the ENE, but it’s still a risk of thunderstorms and a cross-shore wind, making it marginal at best. The combined energy jumps to 1297, but the conditions are just not clean. It’s not a day to get excited about.
There’s a gap of several days with no real quality surf. The wind stays on it, and the swell is inconsistent. We’re looking at a long stretch of poor to marginal conditions until we get past the first week of August.
Now, hold on a second. We get a little glimmer of hope on the 2nd of August. The swell drops to 3ft, but the period stretches out to a very long 16 seconds, turning into a proper groundswell. The combined energy is moderate at 853. The wind is still onshore, though, so it’s going to be a bit of a battle. This is a long way out, so it’s a promising but uncertain prospect. The long period will make it better for a point like Kailua, but the onshore wind will spoil the party.
The real standout, if the forecast holds, is the morning of Wednesday the 5th of August. The swell is 6ft from the ENE, with a period of 12 seconds and a combined energy of 964. The wind is a moderate cross-onshore, which is ‘moderate cross-onshore and choppy’. It’s not perfect, but it’s the best we’ve got on offer in the whole run. It’s a solid, intermediate-sized swell. Keep your eyes on that one.
After that, it tails off again. The wind stays on it, and the swell drops. The 6th and 7th of August have some knee-to-waist high stuff, but the wind is still cross-onshore, and the energy is weak. The 8th of August is the same story.
So, the bottom line is: the first week is a no-go. The second week has a couple of flickers, but the best bet is the morning of the 5th of August. It’s not a classic, but it’s the best we’ve got. Kailua Beach is a point break, so it needs that clean, offshore wind, and we’re just not getting it. It’s a tough run.
Rusty out.

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.
