Alright, Rusty here, checking in on the surf. We’ve got a solid run of waves coming up for Impossibles, a reef break that’s as reliable as they come. The water is sitting at 81°, which is about average for this time of year.
The first real swell hits on Thursday, July 9th. It’s a 7ft SSW groundswell with a very long 15-second period. The wind is a fresh offshore from the ESE, keeping things clean. The combined energy is a hefty 2171, so there’s a lot of power in the water. This is a big one, best left for the experienced crew. This pattern continues into Friday, July 10th, with a 6ft swell and the same fresh offshore wind.
By Saturday, July 11th, the swell drops to 5ft from the SW, but the period is still a solid 14 seconds. The wind is a moderate offshore, and the conditions are looking very good. The energy drops to 1164, but it’s still a solid pulse. This is a good day for the advanced surfers.
Sunday, July 12th, through Monday, July 13th, the swell fades to around 3ft, but the wind stays offshore. The energy is weak, dropping to 399. These are small, clean days for the longboard or a fun fish.
Then we get a second pulse on Tuesday, July 14th. The swell jumps to 6ft from the SSW, with a 17-second period. The energy is massive at 2603, and the wind is a fresh offshore. This is a standout for the experts. The swell stays solid through the middle of the month, with the best of the second week looking like Tuesday, July 21st. The swell is 6ft from the SSW, period at 16 seconds, and the wind is a gentle offshore. The energy is 1371, and the forecast is calling for excellent conditions for experienced surfers.
The final days, from July 22nd to the 24th, ease off to 4ft to 4ft, with the wind staying offshore or cross-off. The energy is lower, but it’s still clean and rideable.
The standout is Saturday, July 11th, for the best mix of size and clean conditions, and Tuesday, July 21st, for the excellent quality. Impossibles is a very consistent reef, and if you can handle the power, it’s going to be great. Crowds are possible, but the reef usually keeps the lineup manageable.
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.
