The Lowdown
Alright, Rusty here. Let’s talk about Kealia for the next couple weeks. It’s a tough one – we got some size coming through, but the wind is just gonna wreck it. Onshore and sideshore winds are the story, and it’s not a good one.
Kealia is a beach and reef setup, pretty consistent, and it wants swell from the NE. Water’s about normal for the season.
We kick off Thursday, July 30th, with 1.4m to 1.6m swell from the ENE, period a short 8 seconds. Energy is weak to moderate (255 to 299). But we got a cross-onshore breeze turning onshore. It’s poor and choppy – don’t bother.
Friday the 31st sees the swell hit 1.8m from the east, still short period. Energy is moderate (609 to 625). Wind is howling onshore at 25 km/h. Choppy, blown out. Saturday the 1st of August pushes to 2.5m from the east, 8 seconds, with strong energy at 1096. But with 30 km/h onshores, that’s a kiteboarding day, not a surfing one.
Sunday the 2nd stays big at 2.5m from the ENE, period 9 seconds, energy very strong at 1175. Wind is still onshore at 25-30 km/h. Monday the 3rd drops to 1.8m, but the wind is the same story.
Tuesday the 4th offers a glint of hope – 1.6m from the ENE, but the period jumps to 11-12 seconds, a proper groundswell. Energy is moderate to strong (582 to 669). But for a beach and reef, that long period will make it close out and wall up. And it’s still onshore wind at 15-20 km/h. It’s poor.
From Wednesday the 5th, it’s all downhill. Swell fades from 1.3m down to under 1m in the second week. Period goes short, and the wind is still from the east or northeast, always on it. There’s no clean window.
It’s a long stretch of bad surf. Kealia is usually pretty consistent, so this is a rough patch, but it’s what we’ve got. No standout days here. Keep your board dry.
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.
