The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s in store for Kailua Beach.

Straight up, I gotta be honest with you – the outlook for the next two weeks is a tough one. It’s not looking good at all. There’s no real standout swell window for clean surfing. The wind is just relentless, coming in from the ENE and E, which is cross-on or onshore for almost every session. That’s a real heartbreaker for a spot that can be magic.

The combined energy of the swells is moderate, with values in the hundreds (like 374), but it doesn’t matter because the conditions are just messy. The water temperature is at 80°, which is about average for this time of year, no surprises there.

The first few days are a write-off. Monday the 3rd starts us off with a 5ft ENE swell, but with a stiff 12 mph NE wind straight onshore, it’s just blown out. Tuesday the 4th isn’t any better, with a 5ft swell and a cross-on breeze making it choppy.

We grind through the rest of the week with the same story. Wednesday the 5th, Thursday the 6th, Friday the 7th – all showing poor surf conditions. The swell is there, between 2ft and 5ft, but the wind is ruining it. The periods are short, too, mostly 8 seconds or less, so there’s no real punch to the waves.

The weekend of the 9th and 10th sees the swell pushing up to 6ft and 6ft, but the wind cranks up to 19 mph. That’s a fresh breeze, creating lumpy, choppy conditions. The combined energy hits 340 to 397, but it’s all for nothing if you can’t get a clean face.

The second week doesn’t offer any relief. From Monday the 11th through to Monday the 18th, it’s the same pattern. The swell actually gets bigger, hitting 7ft and 8ft by the 14th and 15th, with combined energy climbing into the 500s and 600s. That’s some serious power, but the wind is still cross-on or onshore, and the period is short, around 7 to 8 seconds. At 8ft, that’s expert territory if it were clean, but with that wind, it’s a battle. For a beach and point setup like this, it’s honestly looking more like a kite-surfing session than a paddle-in day.

So, the bottom line is this: there are no good surf options in this 16-day window. It’s a blank run, plain and simple. The consistent ENE wind is the villain here. It’s a tough run for the area, but forecasts can change, so keep your eyes peeled. For now, I’d leave the board at home.

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.
