The Lowdown
G'day, Rusty here. We've got a decent run of surf lining up at Conchalio over the next couple of weeks. The water is sitting at a warm 86°, which is about normal for this time of year.
Things kick off this Friday morning, August 14, with a glassy 4ft SW swell rolling in. The period is a very long 18 seconds, so it's proper groundswell with plenty of energy (799), and the water is completely flat. This combo is going to produce some clean, well-shaped waves. The best bet of the whole forecast is Saturday morning, August 15. We're looking at a slightly bigger 5ft SW swell, still with a very long 16-second period, the energy is pumping (1074), and it's glassy. This is the standout—excellent conditions for experienced surfers.
Sunday morning, August 16, holds clean 4ft SW swell with a 15-second period and a light cross-offshore breeze, keeping things tidy. Monday morning, August 17, serves up clean 4ft SW swell, and Tuesday morning, August 18, has glassy 3ft SW swell. Wednesday morning, August 19, is another glassy morning with 3ft SSW swell, though there's a risk of thunderstorms later.
The surf drops off a bit toward the end of the week. Thursday morning, August 20, has glassy 2ft SW swell, and Friday morning, August 21, is flat with only 2ft SSW swell. There's a small spike on Saturday morning, August 22, with 3ft S swell and a glassy morning, but the period is short at 10 seconds.
The following week starts quiet. Sunday, August 23, through Wednesday, August 26, mornings are glassy with small 2ft to 3ft SSW swells. Thursday morning, August 27, is glassy but tiny at 2ft. Then, on Friday morning, August 28, we see a nice pulse of 3ft SSW swell with a very long 17-second period, glassy conditions, and strong energy (771). Saturday morning, August 29, is also looking promising with a glassy 4ft SSW swell, 16-second period, and solid energy (739).
So, to wrap it up: Saturday morning, August 15, is your absolute standout. The clean conditions and solid groundswell will be magic. The end of the month, around August 28-29, is also worth keeping an eye on as a promising but less certain long-range option.

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