The Lowdown

Alright, Rusty here. Let’s take a look at what’s on offer for Kailua Beach over the next couple of weeks.

To be straight with you, the entire 16-day window is a bit of a struggle. Every single time slot is marked as having poor surf conditions, so I can’t really point to a standout session. It’s a tough run.

We start off Tuesday afternoon, July 14th, with a weak, short-period swell from the NE at 4ft and a period of only 7 seconds. The wind is a gentle onshore breeze at 9 mph, but the water temp is a normal 79° for this time of year. The combined wave energy is low (219). It’s not looking good.

The whole first week stays in this same rut. Swell heights bounce between 3ft and 5ft, but the period is usually a short 6 to 8 seconds, meaning weak, messy waves. The wind is almost always a cross-onshore breeze from the E or ENE, ranging from 9 to 19 mph, keeping the surface choppy and lumpy. Thursday morning the 16th is a good example: 4ft from the E at 6 seconds, with a moderate cross-onshore wind at 12 mph. The energy is weak (143). Not something you’d paddle out for.

The second week doesn’t break the pattern. From Sunday the 19th through to the end of the month, every day is either a cross-onshore or onshore wind, with only a few morning slots showing onshore winds. The swell stays small to moderate, with heights up to 6ft on the 25th, but always with a short period of 6-7 seconds. The combined energy does climb into the moderate range, hitting 466 on the 25th and 571 on the 26th, but the poor surf quality rating sticks.

There’s a glimmer on Monday the 27th, where the swell period jumps to 14-15 seconds and the energy hits 685-741, but look at the size – only 3ft. That’s a long-period, small groundswell that would be better suited for a reef or point break, not a beach setup like this. The wind is onshore, but even then, the forecast still says “poor surf conditions.”

So, honestly, there are no good options here. The consistency is low, the wind is nearly always wrong, and the wave quality never breaks through. For a spot like Kailua Beach, a blank run like this is more normal than you’d hope. It tends not to stay poor for long, but for now, the forecasts can change. Keep an eye on it, but don’t hold your breath.

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.
