The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Kealia.
Alright, so the honest truth is, we’ve got a rough stretch ahead. For the first week and a half, from Monday the 20th of July all the way through to around Friday the 31st, the onshore winds are just relentless. The swell is up and down, but the wind is blowing straight onshore from the ENE or E, 15 to 16 mph, and it’s just trashing the surface. The energy is there, but the quality is not. We’re looking at a lot of "poor surf conditions" here, and the scores reflect that. It’s a long gap of nothing special.
The real story starts to change around Monday the 27th of July. The combined swell energy jumps into the four-figure range (1712), and by Tuesday the 28th, the wind shifts. For the first time, we get a cross-on breeze from the NNE on the Tuesday afternoon, and the surf is called "marginal". That’s still not great, but it’s a sign of life.
The best window of the whole 16-day run, and it’s not even close, is Wednesday the 29th of July. The morning is looking like the best on offer. Swell is a solid 8ft out of the ENE, and the wind is a gentle 9 mph from the NE – that’s onshore, but it’s light. The combined energy is a massive 2064, so there’s plenty of push. The water temp is 80°, which is about normal for this time of year. For a fairly consistent, advanced break like Kealia, this is the one to pencil in. It’s big enough to be for experienced surfers only, over 8ft, so keep that in mind. The direction is NE, which is solid for this exposed spot, but the optimum is NE, so it’s a good match.
After that Wednesday, it drops off again. The swell sticks around but the energy fades, and by the end of the first week of August, the swell is dropping below 3ft, even though the period gets long (14 seconds). That long period on a beach and reef setup with small waves can be a bit weird, and the wind is still onshore. Thursday the 4th of August is about the last day that has any real energy, but it’s weak.
So, to wrap it up: if you’re a local or a keen traveler, hold your horses until Wednesday the 29th of July. That’s your standout. The rest of the run is a write-off for quality surfing. The conditions are just too windy and messy for most of it.
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.
