The Lowdown

Alright folks, Rusty here. Let's be real with you. I've scanned the charts for the next couple of weeks, and it's a bit of a rough stretch for us here in Kailua. The short version: the ocean is going to be working, but not in our favor. It's a waiting game.

We're looking at a long, flat, and bumpy run of days to start. The waves will be there, but they'll be a mess – all short-period, wind-blown junk. The energy is weak, sitting in that 162 to 462 range, which means the ocean just doesn't have any push behind it. It's the kind of surf that'll have you paddling around more than actually riding.

This all starts Wednesday the 26th and runs right through the first week of September. Every morning and afternoon is just more of the same: onshore ENE winds, swell hovering around 5ft to 6ft from the east-northeast with a pitiful 6-8 second period. The conditions are going to be lumpy, choppy, and just plain poor. Honestly, for the paddle surfers, it’s a write-off.

There's no two ways about it, you're better off doing something else until this blows over. The wind is just too strong and too on it to make anything work.

Now, here's the light at the end of the tunnel. Things start to shift around the 7th of September. We finally see that ENE wind swing around to the northwest, giving us a cross-off breeze and some cleaner conditions. It's a sign, but the swell is still weak. Then on Monday the 8th of September, it gets interesting. The wind goes light and offshore from the southwest, and the ocean finally cleans up. We've got 6ft of east-northeast swell, and the energy is starting to build. It's the first day that has any real potential.

But the real standout, the one I'm circling on the calendar, is Thursday the 10th of September. The guidance is showing a serious pulse of energy, jumping to 1289, which is a strong signal. We're looking at a 8ft east-northeast swell with a moderate offshore breeze. This is the day. It’s a big, powerful swell for Kailua Beach, but with that offshore wind, it could be proper. A word of caution though: that size and power is for experienced surfers only. It'll be pushing limits. Also, with this being a point break, the longer-period energy can make it a bit tricky and line-y, but the quality should be there. It's a promising outlook, but being that far out, we keep our fingers crossed.

The water temp is running about average for this time of year, so nothing out of the ordinary there. Just the usual boardies and maybe a light vest.

So, keep your head up. Suffer through the flat, bumpy days, and get ready for that Thursday the 10th. It could be worth the wait.

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.
