The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

We’re looking at a solid run of surf at Impossibles, a very consistent reef break that’s fairly exposed to the SW swell. The water temp is about average for the time of year, nothing to write home about.

The first week kicks off from Tuesday the 21st with a moderate groundswell from the SSW. The combined wave energy is strong at 1326, with swell heights around 5.6 ft. Winds are a steady offshore ESE breeze, so the lineup will be clean. This is a solid, rippable wave for experienced surfers, though it’s not the standout of the forecast. There’s a bit of rain around, but the wind is good.

Wednesday the 22nd sees the swell drop a notch, still clean with offshore winds, but the energy comes down to 771. It’s a bit smaller, but still plenty of fun for the crew who know the break.

Thursday the 23rd stays clean, with a long-period 14s SSW swell. The energy is moderate at 830, and the wind is cross-offshore, so the wave face will be well shaped. The swell is smaller, around 3.9 ft, so it’s very user-friendly.

Friday the 24th is interesting. The swell is small, 2.3 ft to 3.0 ft, but the period jumps to 17s – that’s a very long groundswell. The energy is moderate at 722 and 888. With a clean offshore breeze, these waves will have a lot of push for their size, but that long period can make it break a bit straight at the reef. Still, it’ll be clean and fun for the attentive surfer.

Saturday the 25th picks up again with a 4.3 ft SSW swell, 15s period, and strong energy at 1136. Fresh offshore winds keep it clean. This is a cracking morning session.

Sunday the 26th has a shift. The swell turns to the SE, shorter period at 8s, and a bigger 6.9 ft. The energy is still strong at 895, but the wind is a strong offshore ESE at 25 mph. The wave comment says “hard to paddle into.” That’s your caveat: the wind is almost too strong, making the surface lumpy and choppy despite being offshore. The swell is also short-period windswell, so the shape won’t be as good. This is more for the hardcore chargers.

Monday the 27th is similar. The SE swell is 7.9 ft in the morning, again short period, but the wind is a bit lighter. The energy is very strong at 1300, but the quality is still being held back by the short period and strong wind. Not the best day.

Tuesday the 28th sees a return to a long-period SSW groundswell. The afternoon has a moderate 3.0 ft with 16s period and 779 energy, and the wind is lighter. The comment says “expect very good surf conditions.” This is a clean, glassy-feeling session.

Now for the standout. Wednesday the 29th and Thursday the 30th are the pick of the forecast. On Wednesday, the wind drops to a light 6 mph offshore, making it clean as a whistle. The swell is 3.6 ft, 14s SSW, with moderate energy. On Thursday the 30th, conditions are absolutely prime: glassy conditions in the morning with a 4.9 ft SSW swell, 16s period, and strong energy at 1328. The afternoon gets even better with 4.6 ft, 15s, and energy at 1460, and the comment says “excellent surf conditions for experienced surfers.” This is the best on offer – clean, strong, long-period groundswell, and light winds. The crowds are possible at Impossibles, and with waves this good, you’ll want to be out there early.

The weekend of the 31st and 1st of August sees a shift. The wind turns cross-shore, and the swell direction swings to the SW. The combined energy is very high, hitting 2081 and 2581 on the 1st, with 5.6 ft to 6.9 ft swell. The period is very long again at 18s. The wind is light, so it’s clean, but the cross-shore element will put a bit of a crinkle on the face. For the 1st of August, the afternoon comment says “excellent surf conditions for experienced surfers.” This is a solid option for the advanced crew.

Sunday the 2nd of August holds a strong 6.6 ft SW swell with 16s period, energy at 1932, and gentle offshore winds. Clean and powerful.

The second week continues to deliver. Monday the 3rd is a bit smaller, 4.9 ft, still clean. Then Tuesday the 4th and Wednesday the 5th of August see a powerful SSW groundswell with a period of 20s and 18s, and energy skyrocketing to 2249 and 3333. That’s very strong wave energy. The winds are moderate offshore, so the waves will

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.
