The Lowdown
Alright, grab a coffee and listen up. Rusty here, giving you the lowdown on your local stretch.
There’s a nice little run of surf coming our way, starting real soon. We’re looking at a solid, consistent pulse of SSW groundswell that’s gonna keep things interesting for quite a while. The water is sitting at a warm 86°F, which is a touch warmer than usual for this time of year, so you can leave the extra rubber at home.
The first call is for Friday morning, August 7th. Head down to Conchalio for some clean, glassy conditions, with a 2-foot swell coming from the SSW with a very long 18-second period. The combined energy is weak (313), but those long-period lines will offer some shape. The offshore NE wind at 3 mph will have it looking like a pond. The afternoon gets messy as the wind swings onshore, so get your session in early.
Saturday morning, August 8th is where it starts to get good. The swell bumps up to 3 feet from the SSW, still with a long 16-second period. The energy is building (621), and with glassy conditions and a light N wind, it’s going to be a beauty. The morning is the standout for the weekend.
Sunday morning, August 9th is another winner. The swell holds at 4 feet from the SSW, period drops a touch to 14 seconds, but the energy is still strong (609). The wind is dead calm, glassy, and perfect. This is your call for the weekend.
We then have a run of solid, clean mornings through the next week. Monday morning, August 10th (3 feet, 13s, 445 energy), Tuesday morning, August 11th (3 feet, 13s, 451 energy), Wednesday morning, August 12th (3 feet, 16s, 501 energy), and Thursday morning, August 13th (2 feet, 15s, 292 energy) all offer clean, glassy conditions with light offshore wind. The crowd factor is ‘sometimes’ at Conchalio, so you might have some company, but the quality will be worth it.
Looking further ahead, the real highlight might be the following week. Friday morning, August 14th sees a nice jump in swell to 4 feet from the SW, 18-second period, and a big jump in energy (867). The wind is light and glassy from the east. Saturday morning, August 15th is the best of the bunch for the whole outlook. The swell hits 5 feet from the SW with a 16-second period, and the combined energy is pumping (959). It’s dead calm, glassy, and looks like it will be firing. This is a bit of a standout, but it’s a week and a half away, so keep an eye on it.
The mornings of Sunday, August 16th (4 feet, 15s, 543 energy) and Monday, August 17th (4 feet, 14s, 553 energy) still look good with clean conditions. After that, the pattern continues with clean mornings from Tuesday, August 18th through Saturday, August 22nd, with swell sizes hovering around 3 feet to 4 feet and a mix of SSW and SW swell. The energy stays moderate, and the wind is light and offshore or glassy most mornings.
The afternoons are a write-off for most of the period, with cross-onshore or onshore winds and choppy conditions. Stick to the morning sessions and you'll be laughing. The best best of the lot is Saturday morning, August 15th.

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.
