The Lowdown

Alright, this is Rusty checkin' in from the water’s edge. We’ve got a solid run of surf on the way at Impossibles, a standout reef break that’s been cranking. The water temp is sitting at 79°F, which is pretty much dead on average for this time of year—no wetsuit needed, just a board and some wax.

The pattern kicks off with a nice pulse. Tuesday afternoon, August 25th, we’re looking at a clean 6ft SSW groundswell with a long 16-second period, pushed by a moderate offshore breeze from the SE. The energy is moderate to strong (1335), and the conditions are shaping up for experienced surfers. This is a reef break, so that long period will wrap in nicely.

Wednesday, August 26th, keeps the goods coming with a 5ft to 5ft SSW swell, still offshore winds, and very clean conditions. The energy drops a bit (845-1016), but it’s still quality surf. Thursday the 27th gets a little trickier with cross-offshore winds, but the swell stays at 5ft from the SW with a 15-second period, and the energy jumps up (2829). It’s a bit more marginal, but there’s still plenty of push.

Friday, August 28th, is a standout. Morning brings a clean 8ft SSW swell, 16-second period, and light offshore winds. The energy is strong (3616), and it’s excellent for experienced surfers. This is the kind of day that gets the heart pumping. Saturday, August 29th, stays solid with 7ft SSW swell, clean conditions, and energy around 1671. Sunday the 30th drops a bit to 5ft, but still offshore and clean.

Then we hit a bit of a lull. Monday, August 31st, picks up again with a 6ft SSW swell and a very long 18-second period. The energy is strong (2146), and the winds are offshore. This long period will work well at Impossibles, a reef break, so expect some proper lines. Tuesday, September 1st, keeps it going with 6ft to 7ft SW swell, still offshore, and energy over 2000. The conditions are good, but it’s a bit more questionable on the tide.

The first week of September holds steady. Wednesday the 2nd has 6ft SW swell, offshore winds, and strong energy (2048). Thursday and Friday the 3rd and 4th taper off a bit to 4ft-5ft, but still with offshore winds. Saturday, September 5th, brings a bit of rain and a cross-offshore breeze, but the swell is 6ft SSW with a long 18-second period and energy at 2387. It’s a bit messy, but there’s raw power.

Sunday, September 6th, sees 7ft SSW swell, cross-offshore winds, and energy around 2152. Not the cleanest, but it’s big. By Monday the 7th, we’re back to cleaner conditions with 5ft SSW swell and gentle offshore winds.

Now, here’s the real standout: Tuesday, September 8th, and Wednesday, September 9th. Tuesday morning has a 3ft SSW swell but with a super long 22-second period and energy at 1449. That’s a deep ocean swell, and at Impossibles, it’ll translate into smooth, powerful waves. Wednesday the 9th is the absolute highlight: 8ft SSW swell, 18-second period, and massive energy (4707 in the morning, 4324 in the afternoon). Offshore winds all day, clean conditions. This is a top-tier day for experienced surfers only—it’s big, powerful, and perfect. If you’re an expert, mark your calendar.

Crowds are possible at Impossibles, especially on the best days, but it’s worth it. The reef break handles the long-period swells beautifully, and the offshore winds are a major plus. No beginner stuff here—this is for the crew who know what they’re doing.

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.
