The Lowdown
G'day, Rusty here. It's a tough stretch ahead for Kealia. The whole 16-day window is pretty much a write-off, with no good surf options on the menu. We're looking at a solid two-week gap where the conditions just aren't friendly.
The water temperature is about average for this time of year, nothing unusual there. But the real story is the wind. We've got a persistent moderate breeze from the east and east-northeast, blowing straight onshore for the entire first week and a half. That's wrecking any chance of clean waves. The swell is all short-period windswell, mostly under 8 seconds, so the energy is weak to moderate (usually between 300 and 500). It's gonna be choppy and messy.
From Saturday the 30th of August right through to the end of the first week, it's all "poor surf conditions" with a big fat zero score. The swell hangs around 5 ft to 7 ft, but with that onshore wind, it's just a washing machine. Not worth paddling out for.
The second week starts to get a bit more interesting, but it's still not good. On Monday the 7th of September, the energy jumps up big time, hitting 1055 (moderate) in the morning, and then 2346 (strong) in the afternoon with an 8 ft swell from the east. The wave comment changes to "marginal" – a glimmer of hope, but still with onshore wind. That size is pushing into expert territory, and with the wind, it's a mess.
Tuesday the 8th sees the swell peak at 10 ft, but it's still onshore and the energy is strong (over 1000). That's purely for the hardcore, and even then, the conditions are poor. Later in the week, the wind drops to a light breeze on Thursday the 10th, and the swell drops to 6 ft with the energy around 500. The wave comment is "marginal" again, but with a cross-onshore wind, it's still not clean. The last few days of the outlook fade back to poor surf with small, weak windswell.
Honestly, for a beach and reef setup like Kealia, this pattern is often more interesting for kite surfing than paddle surfing. It's a blank run, but these things don't last forever. Keep an eye on the forecasts, things can change.
Rusty.

Information about the Kealia Surf forecast
The above surf forecast table for Kealia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kealia can be found by selecting the local surf guide option on the grey menu. Our Kealia 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 (Kealia) 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 Kealia 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.
