The Lowdown

G'day, I'm Rusty, and I'm looking at the surf outlook for your local stretch of coast. We've got a long 16-day window ahead, but fair warning – it's a slow start with a lot of onshore wind and poor conditions. The first real standout doesn't appear until Wednesday the 9th of September, so there's a solid gap of over a week where the surf is just not worth paddling out for.

The main break on the radar is Kealia, a beach and reef setup that's fairly consistent. Right now, the water temperature is about average for this time of year, so nothing unusual there.

From Wednesday the 26th of August all the way through to Tuesday the 8th of September, the story is all onshore winds – mostly from the east and east-northeast, blowing between 12 mph and 18 mph. The swell is small, mostly 4ft to 6ft from the east, with a short period around 7 seconds, which means weak, choppy, and messy waves. The combined energy is moderate, ranging from 119 to 544 (moderate), but it's all poor surf conditions and zero scores. You'll want to leave the board in the car for this stretch.

Now, finally, on Wednesday the 9th of September, things start to look up. The morning brings a light offshore wind from the west at 3 mph, and the swell is 6ft from the east-northeast with a 7-second period – still short period, but the offshore wind will clean it up. The combined energy is 441 (moderate), and the wave comment says "expect good surf conditions." This is your best window. The afternoon of the 9th gets even better with a moderate offshore breeze from the west-southwest at 12 mph, still 6ft from the east-northeast, but the combined energy jumps to 532 (moderate), and the comment says "expect very good surf conditions." This is the standout – clean, offshore winds, and a decent size for advanced surfers. Keep in mind, Kealia is an advanced spot, and the swell direction is from the east-northeast, which is close to its optimum from the northeast, so it should wrap in nicely.

Thursday the 10th of September is a bit more marginal. The morning shows a 6ft swell from the east with an 8-second period, combined energy at 716 (strong), and a cross-offshore wind from the south at 15 mph. The comment says "marginal surf forecast or questionable tide conditions," but it's still clean. It's a secondary option, but the real prize is Wednesday.

The crowds at Kealia can be a problem, as they're often there, but with the quality on offer on the 9th, it's worth the company.

So, if you're an advanced surfer, pencil in Wednesday the 9th of September. The rest of the window is a write-off. Keep an eye on the forecasts, as things can change, but for now, that's the call.

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.
