The Lowdown

Hey folks, Rusty here with the rundown for ADs/Doubles. Staring down the next 16 days, and it’s a rough stretch. The wind is blowing cross-shore or cross-onshore, mostly out of the east-northeast, with fresh to strong breezes that are keeping things messy and lumpy. The swell is coming from different directions at times, creating a chop that’s no good for clean surfing. It’s gonna be a real grind, so don’t count on much to ride.

From Saturday, August 10 through Tuesday, August 13, the swell sits around 5ft, but the period is short—only 6 to 8 seconds—and the wind is cross-shore from the east-northeast or northeast at 19 to 25 mph. The combined energy is low to moderate, mostly between 273 and 1122 units, but the bumpy conditions ruin any chance of decent surf. The water temp is about average for this time of year, so no surprises there, but that doesn’t help when the surf is so poor.

Things get bigger but nastier toward the end of the week. On Friday, August 14, the swell jumps to 10ft with a short 8-second period, and winds crank up to 31 mph from the east-northeast—near gale force—making it a total mess with crossing waves. Then Saturday, August 15, sees the biggest swell of the entire outlook at 13ft to 15ft from the east, but again the period is short at 9 seconds, and the wind is cross-shore to cross-onshore at 25 to 28 mph. The combined energy hits 3650 units, but it’s all chaos—big, ugly, and dangerous for anyone but experts, and even then the wind will make it a frustrating session.

After that, Sunday, August 16 brings a 10ft swell from the south with a longer period of 12 seconds, which would normally be promising, but the cross-shore wind at 25 mph from the east-northeast kills it. The energy is massive at 3962 units, but the strong cross-shore mess ruins any chance of clean waves.

From Monday, August 17 through the end of the outlook on Sunday, August 23, the swell drops back to 2ft to 6ft, with periods mostly short at 6 to 8 seconds, and the wind stays stubbornly cross-shore from the east-northeast at 12 to 22 mph. The combined energy falls to between 250 and 810 units, and it’s all lumpy cross-chop. No standouts here—just a string of poor surf days.

The only glimmer might be the early morning of Sunday, August 16, where the south swell has some period to it, but the wind spoils it. Honestly, there’s nothing in this 16-day stretch worth paddling out for. If you’re itching, you might find a tiny window on the smaller days with lighter wind, but it’s a long shot. Keep your board in the car and wait for a better pattern to roll in.

Information about the ADs/Doubles Surf forecast

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