The Lowdown
Alright, this is Rusty. Let's talk about what's on the menu for the next couple of weeks.
Right off the bat, for Kailua Beach, it's a tough stretch. The onshore trade winds are on the nose or cross-on for the vast majority of the forecast period, which is a real bummer. The water temperature is sitting right around 80°F, which is pretty much average for this time of year, nothing weird there.
The first real chance of anything surfable doesn't show up until Monday, July 27th, and even then it's a marginal call. You'll see a new groundswell push in from the east, around 5 feet, but the period is a solid 14 seconds. That's a long-period swell, which brings a lot of energy, but it's breaking straight at a beach break. You'd want a point or reef for that kind of power. The wind is onshore, so it’s not going to be clean.
Tuesday, July 28th, is the best of a bad bunch. The swell eases slightly to about 6 feet from the east, still with a decent 13-second period, and the wind turns light from the north-northeast (9 mph). That's the best wind we see all period, and it's onshore, but it's light enough that it might be workable. This is your only real window to consider paddling out, but keep expectations low.
After that, it's back into the grinder of poor conditions. The wind picks up again, and the swell gets messy and choppy. We get a big pulse of swell around August 1st and 2nd, with heights pushing 8 feet, but the wind is howling at 19 mph, cross-on, making it a complete washout. That much swell with that wind is more of a kitesurfing setup than a paddle-surfing one.
Honestly, with the consistency of the trades being so persistent, this is a pretty blank run. Keep an eye on the Tuesday morning window (July 28th) for a possible quick session, but otherwise, this stretch is a write-off.

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.
