The Lowdown

Alright, Rusty here, and I’m looking at a rough stretch for Kailua Beach. The water’s a warm 81°F, which is about what you’d expect for the season, but that’s the only easy part of this outlook.

We’ve got a long run of onshore and cross-onshore winds from the ENE, just tearing up the face. Even when the swell’s coming from the right NE direction, that wind makes it a mess. Starting Monday the 14th, we get a tiny 3ft NE swell with a short 8-second period, but the wind is straight on it. The combined energy is a weak 94—hardly worth paddling out for.

The poor conditions don’t let up for almost two weeks. By Thursday the 17th, the swell jumps to 7ft from the ENE, with the energy climbing to a moderate 498, but the gusty cross-onshore wind makes it lumpy and choppy. That size is pushing into “not for beginners” territory, but it’s all blown out anyway.

The real gap here is long. You’re looking at a blank run until the very end of the month. Finally, around Monday the 28th, things get a little better. The wind eases right down to a light breeze. On Tuesday the 29th, we see a 7ft NE swell with a strong combined energy of 694. The wind goes light and cross-shore from the SE. The swell period is still short at 8 seconds, so it’s wind swell, but with the light wind, it might just clean up enough for some grovelly peaks.

Kailua Beach (Oahu) is a point break that breaks fairly consistently. When there’s a pulse of NE swell, it gets exposed. Crowds are possible, so if that Tuesday morning window opens up, be ready to share the water. The swell direction is spot on for the break’s preference, which is the only real positive in this whole stretch.

That’s the skinny: a long quiet spell with just one slim window late in the game. It can’t stay flat forever, and forecasts can change.

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.
