Impossibles Surf Forecast and Surf Report

G’day, it’s Rusty. We’ve only got one break on the menu this outlook, but what a run it’s shaping up to be. Impossibles is the name, and it’s a reef setup that’s very consistent and rated for advanced crew only. The water temp is sitting at 78°, which is about average for this time of year. The overall pattern is a long sequence of solid, clean surf, almost non-stop from Thursday August 13 through Friday August 28.

First up, Thursday August 13 afternoon. Clear skies, a steady offshore wind from the SE at 16 mph, and a solid 10ft SSW groundswell humming in at 16 seconds. That’s very long-period energy, and with the combined swell energy reading 4103 (strong to very strong wave energy), this is serious stuff. Over 8ft means experts only. The reef will handle this kind of long-period swell beautifully.

Friday August 14 morning keeps the clean theme going with SE offshore at 12 mph, and 7ft SSW swell, still 16 seconds. The energy is 2725, still strong. By the afternoon the wind turns cross-off but the swell holds at 7ft, 15 seconds. It stays solid and workable but not quite as tidy.

Saturday August 15 has a gorgeous morning: cloudy but 9 mph offshore from the SE, 7ft SSW swell with a very long 17-second period. Energy at 2895. The afternoon is just a tick bigger at 8ft, 17 seconds, with 12 mph offshore. This is prime.

Sunday August 16 brings clear skies and gentle offshore from the ESE at 9 mph, 7ft SSW, 16 seconds, energy 2243. The afternoon backs off slightly to 6ft with SE offshore. Still excellent.

Monday August 17 sees the swell drop to 5ft in the morning and 5ft in the afternoon, both with 14-second periods and clean offshore wind. Energy around 900 – moderate now. Still very good, but not the standout window.

We get a boost again Tuesday August 18: morning 6ft, afternoon 6ft, both with 16-second SSW groundswell and offshore ESE/SE winds, energy back into the strong range (2317 and 2577). Clean and powerful.

Wednesday August 19 is a standout. Morning brings 8ft at 18 seconds – that’s a monster very-long-period groundswell – with SE offshore 12 mph. Energy 3762. The afternoon is even chunkier: 8ft, 18 seconds, energy 4374. This is the heart of the swell window. Experts only.

Thursday August 20 keeps the heavy stuff coming: 10ft SW at 16 seconds in the morning, energy 4281. Afternoon holds at 8ft, 16 seconds. Offshore wind both sessions. This is world-class reef surf.

Friday August 21 has morning 7ft at 15 seconds, afternoon 8ft at 18 seconds with energy peaking at 4399 – the highest reading in the run. Offshore wind maintains.

Saturday August 22 starts with 8ft SSW, 16 seconds, offshore, then the afternoon goes cross-off with 7ft. Still good but not glassy.

Sunday August 23 through Tuesday August 25, the swell eases. Sizes run from 6ft down to 3ft, periods between 13 and 17 seconds. Still offshore winds, still clean. Energy stays in the moderate range. A nice run of smaller but well-shaped waves.

Wednesday August 26 to Friday August 28, we see a slight bump: 6ft to 7ft, periods 14–15 seconds, mostly offshore but a couple of afternoon cross-off sessions. Energy climbs back into the strong range, especially Friday afternoon at 3505.

The one true standout here is Wednesday August 19 through Thursday August 20 – that’s the peak. Huge 8ft to 10ft very-long-period SSW groundswell, clean offshore winds, max energy readings. If you’re an experienced surfer and you love a heavy reef, that’s your window. Don’t even think about it if you’re a beginner – this is well over 8ft.

Impossibles can get crowded sometimes, so expect company on the best days. The consistency is very high across this whole 16-day run – no gaps, just solid, clean surf for the crew who know what they’re doing.

Stay safe out there.
