The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking at Impossibles. This is a solid, very consistent reef break that handles a good south-west swell, and it's looking like a real mixed bag over the next couple of weeks, with a serious payoff if you're willing to wait.

The pattern starts off a bit average. The water temperature is about normal for this time of year, nothing out of the ordinary. We’ve got a moderate offshore breeze from the SE keeping things clean, but the swell is a bit messy. Wednesday the 22nd through Friday the 24th, we’re seeing waves around 4ft to 3ft, but the guidance is calling it marginal. The combined energy is moderate (733 to 878), but the period is a mix of 13 to 17 seconds, so there’s some groundswell in there. It’s surfable, but nothing to write home about.

The weekend of the 25th and 26th picks up a little. Saturday morning has a clean 4ft from the SSW with a 15-second period, and the energy jumps to 1146. That’s solid moderate energy. But Sunday sees the swell direction swing to the SE, with a shorter 9-second period and a bump in size to 6ft – 7ft. The wind stays offshore, but that short period windswell is less exciting. It’s a bit of a mixed bag.

We hit a bit of a lull from Monday the 27th through Tuesday the 28th. The swell drops back to 5ft to 3ft, and while the period stretches back out to 15-16 seconds, the energy is weaker (577 to 750). The wind is still offshore, but it’s a fresh breeze, so it’s not the glassiest. Still, it’s clean.

Now, the real standout starts to build from Wednesday the 29th. The consistency is there, and the swell direction locks back into the SSW. The energy climbs through the week, and by Thursday the 30th and Friday the 31st, we’re talking about some serious quality. Wave heights are 4ft with a long, clean 15 to 19-second period. The combined energy is strong (1356 to 1634). This is groundswell with power, and the offshore wind is moderate. The guidance says "excellent surf conditions for experienced surfers" for those mornings. This is the pick of the first week.

The first week of August keeps the party going. Saturday the 1st and Sunday the 2nd see waves push up to 5ft to 7ft, with a solid 15 to 16-second period and energy in the 1400s to 1800s. It’s getting bigger, but it’s still clean and manageable for a good surfer.

But the absolute bomb is sitting out there on Monday the 4th and Tuesday the 5th of August. The finder is showing a massive pulse of swell. On Tuesday the 4th, we’re looking at 12ft from the SSW with an 18-second period. The combined energy? It’s 8096. That’s very strong, heavy-duty energy. Wednesday the 5th is still pumping at 10ft with 16-second period (4423 energy). This is expert-only territory. The swell is over 8ft, with a very long period, so it’s going to be a freight train at this reef. Not for the faint of heart. Even into Thursday the 6th, it’s still 7ft with a 14-second period and 2050 energy. The wind is offshore for all of it, so it should be clean and terrifying. Crowds are listed as "sometimes", so it might not be a zoo, but for a wave this size, you’ll want your wits about you.

This is a classic case of waiting for the big one. The early days are just warm-ups. The real show is the last few days of July kicking off, and then that monster swell in early August. If you’re an experienced surfer, mark your calendar for Tuesday the 4th and Wednesday the 5th of August. That’s the one.

Rusty.

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.
