The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this stretch of the forecast is a tough one for the paddle crew. We’re looking at Kailua Beach, a point break setup that’s exposed to the NE, and right now it’s locked into a pattern that’s more about frustration than fun.
The whole 16-day window is a gnarly run of onshore and cross-onshore winds from the ENE, cranking at 15 to 25 mph for most of it. That’s blowing the guts out of any potential. The wave energy is actually moderate to strong, with combined energy readings hitting three and four-digit numbers like 323 all the way up past 1000 (moderate to strong wave energy), but it’s all messy. The swell is short-period windswell, mostly 7 to 8 seconds, and it’s coming from the same direction as the wind – ENE. That’s a recipe for lumpy, choppy, poor surf conditions. The score is a flat zero for days on end.
There’s a bit of a change around the 28th of July. The wind eases to a gentle breeze, the swell period stretches to 13 seconds, and the combined energy is still strong at 1042 (strong wave energy). The surf is still a bit marginal, with a 1 on the scoreboard, but it’s the best we’ve got. Swell is 5 ft from the E. The wind is onshore from the NE, so it’s not clean, but it’s a whole lot better than the gale-force stuff before it.
Then on the 29th of July, a light breeze, clear skies, and a 6 ft swell from the E with a 12-second period. That’s the closest we get to a window. The water temp is about average for the time of year, nothing freaky. The wave energy is still up there at 932 (strong wave energy). The catch? The wind is still onshore from the NE, so it’s not glassy, but it’s light enough that it might be doable for an intermediate willing to battle the onshore texture.
The rest of the run into early August is just more of the same: strong winds, short period junk, and poor conditions. From the 30th of July through to the 6th of August, it’s a solid block of onshore wind and lumpy surf. The spot can be inconsistent, and crowds are possible at Kailua Beach, but honestly, with conditions this average, you might have it to yourself.
If you’re a kite surfer, this setup looks way more interesting than for paddle surfing. The strong cross-onshore winds and decent swell energy will be a blast for you. For the rest of us, it’s a waiting game. The near-term is a write-off, and the long-range stuff is a big “maybe.” It tends not to stay this poor for long, but right now, there’s no standout. Keep your eyes on the 29th, but don’t get your hopes too high.
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.
