The Lowdown
Alright, Rusty here. Let's have a look at what's coming down the pipe for Kealia.
Honestly, it’s a bit of a heartbreaking outlook for a spot that can get really good. We’ve got a solid 16 days ahead, but it’s mostly a write-off. The first real session that’s even worth talking about doesn’t show up until Tuesday the 8th. Before that, Monday the 7th is a total mess with a risk of thunderstorms, a strong onshore wind, and a jumbled 12 ft of slop.
So, we have a dry spell for a few days to start.
The standout window is a very narrow one on Tuesday afternoon, the 8th of September. That afternoon, the wind finally swings offshore from the southwest, and we’ll see a clean 6 ft swell coming out of the ENE with an 11-second period. The combined energy is moderate at 828, and with the wind cleaning it right up, that’s your best bet. Kealia is a beach and reef set-up, fairly consistent, but it draws an "often" crowd, so expect company in the water. The water temp is sitting right on average for this time of year at 81°, so no surprises there.
After that brief window of hope, it’s back to mediocrity. Wednesday the 9th drops down to 4 ft with a cross-shore breeze, and from Thursday the 10th all the way through to the end of the forecast on the 22nd, it’s a grim run of poor surf. Winds are mostly onshore or cross-onshore, and the swell is consistently small and weak. The energy values dip as low as 100, which is barely a ripple.
For the second week, there’s nothing to get excited about. The swell tries to push back up around 7 ft on the 17th and 18th, but it’s coming straight onshore with a short period (8 seconds) and a fresh breeze in the 19 mph range. That’s going to be a messy, blown-out wall. A couple of mornings further out on the 21st and 22nd show a marginal tide call, but the wind remains onshore, so it’s a no-go.
Honestly, for this stretch, I’d be looking at a different hobby. With the persistent onshore wind and building swell in the second week, this look is more interesting for kite surfing than paddle surfing.
Keep the dream alive, though. It won't stay this poor forever.
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.
