The Lowdown
Hey, Rusty here. Impossibles is your only real option for the next couple weeks, and it's a proper advanced reef break that's very consistent. It loves a SW groundswell, and that's exactly what's coming. Water temp is about 80.4°F, right around average. Offshore winds from the ESE/SE keep things clean, though the wind can be a bit strong at times. Crowds can happen, but it's worth it.
This Sunday afternoon starts with a 4ft SW swell, 13 sec period, moderate energy (899). Fresh offshore, clean but marginal tide. Monday morning jumps to 5.2ft, 14 sec, strong energy (2074). Monday afternoon hits 6.9ft, 16 sec from the SSW – that's a solid groundswell, strong energy (2325). Long period means the reef will shape up nicely, but that size is for experienced surfers only. Tuesday eases to 5.6ft, then 5.2ft, still offshore. Wednesday and Thursday drop to 3.3–4.3ft, clean but weaker energy. Friday the 24th is small, 2.6–3ft, with 17–18 sec periods – very long period, but fat.
Saturday the 25th is a standout – 4.3ft SSW, 15 sec, moderate energy (1059), and "very good" conditions. Moderate offshore winds, clean. That's a solid day. Sunday the 26th has 3.3–4.6ft, but the afternoon shifts to a short-period 8 sec SE swell – messy, skip it. Monday the 27th is tiny, 1.6–2ft, but with a 19 sec period – super long period, weak but maybe fun if you're patient.
Then the real action. Tuesday the 28th: 3.3–3.9ft SSW, 16 sec, moderate energy (909–1287), "very good." Wednesday the 29th and Thursday the 30th are the best. Wednesday morning: 5.9ft SSW, 16 sec, strong energy (1676), "excellent for experienced surfers." Afternoon: 6.2ft, 15 sec, even stronger (1645). Thursday morning: 5.6ft, 14 sec, energy (1322), "very good" – afternoon: 5.2ft, 13 sec, energy (1461), "excellent" again.

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.
