The Lowdown
Alright, surfers, Rusty here. We've got a solid run of swell headed our way, all at one spot.
The forecast is basically an extended run of strong, consistent SSW groundswell at Impossibles. This is a proper reef break, a real wave for advanced surfers only, and it’s very consistent. It’s going to be on for nearly two straight weeks, starting from Tuesday, August 4th. The water temp is sitting at 79°, which is bang on average for the time of year, so no need for a thick suit.
The first standout session kicks off Tuesday afternoon, August 4th. Clean, moderate offshore winds from the ESE are grooming a solid 6ft SSW swell with a 14-second period. The combined swell energy is already pumping at 1148 (moderate to strong). It’s a clean, powerful wave, but the size is pushing into the territory where beginners should be wary.
The real absolute standout, the one you don’t want to miss, is Monday, August 10th, through to Tuesday morning, August 11th. We’re looking at a huge 10ft SSW swell. The Monday afternoon session has a very long period of 18 seconds and a massive combined energy of 5377 (very strong wave energy). Tuesday morning is similar with a 17-second period and 4809 energy. The winds are offshore, keeping it smooth. This is purely for experts – 10ft on a reef is no joke. The long period means it’s a proper groundswell, perfect for a point/reef setup like this, with long lulls between sets. It’s going to be a dream for the guys who can handle it. Expect crowds to be likely, this spot is known for them.
The run continues strong through the rest of the week and into the next. Sunday, August 16th morning still has a clean 6ft swell with a 16-second period, and Monday, August 17th morning packs a punch with a 6ft swell and a very long 19-second period, giving it 3015 energy. The quality holds up well, but the very best of the best is definitely that Monday/Tuesday window around the 10th and 11th.

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