Alright, let’s get into it. This is Rusty, and I’m looking at Kailua Beach for the next couple of weeks.

Right now, and for the foreseeable future, we’ve got a persistent trade wind pattern cranking out of the ENE, which is directly onshore or cross-onshore for this spot. That’s not what you want at a point break – it’s going to mess up the face of the wave and leave the surface choppy and lumpy. On top of that, the swell is almost entirely windswell, with short periods of 7 to 8 seconds, so we’re not getting any real push or shape. The combined swell energy is stuck in the moderate range, but it’s all wind-driven junk. There isn’t a single day in this whole 16-day run that scores well – every entry is flagged as “poor surf conditions.”

For a spot like Kailua Beach (Oahu), which is fairly consistent and exposed to the NE, you’d typically expect some rideable days, but this run is a total dud. The water temperature on July 2nd morning is around 79°, with a tiny anomaly, so it’s about average for the time of year – not that it helps with the surf.

We start on Thursday, July 2nd, morning – clear skies, but 16 mph onshore winds and a 5 ft ENE swell at 8 seconds. Choppy, poor. That same pattern holds through the weekend: Saturday morning, July 4th, 6 ft at 8 seconds, 19 mph onshore. For the Fourth of July, the only fireworks will be the wind blowing out the surface. Sunday, July 5th, gets a little bump in size – 6 ft – but the period drops to 7 seconds and winds pick up to 22 mph onshore. It’s just messy.

The second week doesn’t offer any relief. Monday, July 6th, through to the final day, Friday, July 17th, it’s the same story: ENE windswell between 5 ft and 7 ft, periods mostly 7 seconds, and winds never dropping below 12 mph. There’s one morning on Saturday, July 11th, where the swell drops to 5 ft from the NE, period of 8 seconds – still onshore wind at 19 mph. No improvement.

There are no standouts here. Nothing to get excited about. If you’re a kitesurfer, that 7 ft+ ENE swell with 19-22 mph winds might look interesting for a downwinder, but for a paddle surfer, this is a two-week blank. Honestly, for this spot, that’s not normal – it tends to have more going on, so this stretch is a real bummer. Hang in there, forecasts change, but for now, leave the board in the car.

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.

Kailua Beach is 0 km (0 miles) from Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
