The Lowdown

Alright, this is Rusty, and I gotta be straight with you – looking at the full 16-day window for Kailua Beach, it's a tough one. There’s no real standout window here, and the forecast is pretty much a long stretch of poor surf conditions. The water temperature is sitting at 80°, which is about average for this time of year.

We’re looking at a gap of no good surf right from the start. The entire first week, from Sunday the 2nd of August through to Saturday the 8th, is a write-off. The wind is hammering in from the ENE, mostly onshore or cross-onshore, with speeds up to 22 mph. That’s blowing the top off any potential. The swell is coming from the ENE, which is not the ideal NE direction for this point break, and the period is short, around 8 seconds or less, meaning weak, messy, wind-affected waves. The combined wave energy is moderate at best, hitting 856 on Sunday morning but dropping fast, and the conditions are described as "poor" across the board.

We get into the second week—from Sunday the 9th of August through to Monday the 17th—and it's more of the same. The wind relaxes a little, but it's still onshore or cross-onshore, with speeds of 15-18 mph. The swell height bounces between 4 ft and 6 ft, with a short period of 7-8 seconds, coming from the ENE. The combined energy stays low to moderate, mostly in the 100-300 range, and the condition comments are consistently "poor" or "lumpy." There's a brief moment on Tuesday morning the 4th where the swell period stretches to 11 seconds and the score creeps up to a 1, but with the wind still onshore and the size around 5 ft, it's only marginal at best. Honestly, nothing here is worth getting excited about. The whole 16 days feels like a big blank run for paddle surfing. If you’re a kiter, the consistent onshore wind and lumpy chop might be your thing, but for waves, it’s a no-go.

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.
