The Lowdown

Alright, Rusty here. Let's talk about what's on the menu for Kailua Beach.

Right off the bat, I gotta be straight with you—this 16-day stretch is looking pretty grim for a paddle. We’ve got a lot of days with the wind blowing onshore or cross-onshore, and the swell, while sometimes showing some decent height, is just getting mangled. The wave energy is moderate to strong, hitting values like 678 up to 2193, but with that wind, it’s not translating into anything decent for a surfer.

The water temperature is sitting at about 80°F, which is about what you’d expect for this time of year, nothing unusual there.

Here’s how it shakes out. The whole run from now through the start of August is basically a write-off. Sunday the 26th and Monday the 27th have a mix of short-period swell from the east and northeast, but with onshore winds blowing at 15 to 22 mph, the conditions are just poor. Tuesday the 28th actually sees a bump in swell height up to 8 ft, and the energy spikes to over 2000, but it’s still that onshore wind and a risk of thunderstorms in the morning. Not the kind of session you’re gonna enjoy.

You get a slight glimmer on Wednesday morning, July 29th. The wind drops right off to a light 6 mph from the north, and we’ve got a 10 ft swell from the northeast with an 11-second period. That’s a lot of water moving, solidly in the expert-only zone. The energy is strong at 1729. But here’s the catch – it’s a cross-onshore wind, and the forecast only gives it a marginal nod because of tide or other factors. It’s the only morning in the whole window that even gets a rating above zero, but I wouldn’t call it a standout. It’s a maybe, if you’re an experienced local who knows the sandbar.

After that short-lived hope, it’s back to the doldrums. From Thursday the 30th all the way through to Monday, August 10th—that’s nearly two weeks straight of poor conditions. The wind stays relentless, mainly from the east or northeast, anywhere from 9 to 25 mph, and it’s either onshore or cross-onshore the entire time. The swell sticks around, sometimes chest to head high, but the period is short and the wind chops it all to bits. For a point break like Kailua Beach, that’s a mess. Honestly, with that kind of wind and consistent swell, this setup looks way more interesting for kite surfing than it does for paddle surfing.

There is a tiny window on Tuesday morning, August 4th, where the swell drops a bit to 5 ft, but the wind picks up again and it’s still cross-onshore. Nothing to get excited about.

Bottom line: there is no true standout session here. The only day that even flirts with being surfable is Wednesday the 29th, and that’s a long shot. For the rest of the 16 days, you’re better off checking the forecast for another break or just taking the time off.

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.
